GENERAL DESCRIPTION
The ADSP-BF70x processor is a member of the Blackfin®
family of products. The Blackfin processor combines a dual-
MAC 16-bit state-of-the-art signal processing engine, the
advantages of a clean, orthogonal RISC-like microprocessor
instruction set, and single-instruction, multiple-data (SIMD)
multimedia capabilities into a single instruction-set architec-
ture. New enhancements to the Blackfin+ core add 32-bit MAC
and 16-bit complex MAC support, cache enhancements, branch
prediction and other instruction set improvements—all while
maintaining instruction set compatibility to previous Blackfin
products.
The processor offers performance up to 400 MHz, as well as low
static power consumption. Produced with a low-power and low-
voltage design methodology, they provide world-class power
management and performance.
By integrating a rich set of industry-leading system peripherals
and memory (shown in Table 1), the Blackfin processor is the
platform of choice for next-generation applications that require
RISC-like programmability, multimedia support, and leading-
edge signal processing in one integrated package. These applica-
tions span a wide array of markets, from automotive systems to
embedded industrial, instrumentation, video/image analysis,
biometric and power/motor control applications.

ADSP-BF700/701/702/703/704/705/706/707
BLACKFIN+ PROCESSOR CORE
As shown in Figure 1, the processor integrates a Blackfin+
processor core. The core, shown in Figure 2, contains two 16-bit
multipliers, one 32-bit multiplier, two 40-bit accumulators
(which may be used together as a 72-bit accumulator), two
40-bit ALUs, one 72-bit ALU, four video ALUs, and a 40-bit
shifter. The computation units process 8-, 16-, or 32-bit data
from the register file.
The compute register file contains eight 32-bit registers. When
performing compute operations on 16-bit operand data, the
register file operates as 16 independent 16-bit registers. All
operands for compute operations come from the multiported
register file and instruction constant fields.
The ALUs perform a traditional set of arithmetic and logical
operations on 16-bit or 32-bit data. In addition, many special
instructions are included to accelerate various signal processing
tasks. These include bit operations such as field extract and pop-
ulation count, divide primitives, saturation and rounding, and
sign/exponent detection. The set of video instructions include
byte alignment and packing operations, 16-bit and 8-bit adds
with clipping, 8-bit average operations, and 8-bit subtract/abso-
lute value/accumulate (SAA) operations. Also provided are the
compare/select and vector search instructions.
For certain instructions, two 16-bit ALU operations can be per-
formed simultaneously on register pairs (a 16-bit high half and
16-bit low half of a compute register). If a second ALU is used,
quad 16-bit operations are possible.
The 40-bit shifter can perform shifts and rotates and is used to
support normalization, field extract, and field deposit
instructions.
The core can perform two 16-bit by 16-bit multiply-accumu-
lates or one 32-bit multiply-accumulate in each cycle. Signed
and unsigned formats, rounding, saturation, and complex mul-
tiplies are supported.

The program sequencer controls the flow of instruction execu-
The assembly language, which takes advantage of the proces-
sor’s unique architecture, offers the following advantages:
• Seamlessly integrated DSP/MCU features are optimized for
both 8-bit and 16-bit operations.
• A multi-issue load/store modified-Harvard architecture,
which supports two 16-bit MAC or four 8-bit ALU + two
load/store + two pointer updates per cycle.
tion, including instruction alignment and decoding. For
program flow control, the sequencer supports PC relative and
indirect conditional jumps (with dynamic branch prediction),
and subroutine calls. Hardware supports zero-overhead loop-
ing. The architecture is fully interlocked, meaning that the
programmer need not manage the pipeline when executing
instructions with data dependencies.
• All registers, I/O, and memory are mapped into a unified
4G byte memory space, providing a simplified program-
ming model.
• Control of all asynchronous and synchronous events to the
processor is handled by two subsystems: the core event
controller (CEC) and the system event controller (SEC).
The address arithmetic unit provides two addresses for simulta-
neous dual fetches from memory. It contains a multiported
register file consisting of four sets of 32-bit index, modify,
length, and base registers (for circular buffering), and eight
additional 32-bit pointer registers (for C-style indexed stack
manipulation).
The Blackfin processor supports a modified Harvard architec-
ture in combination with a hierarchical memory structure. Level
1 (L1) memories are those that typically operate at the full pro-
cessor speed with little or no latency. At the L1 level, the
instruction memory holds instructions only. The data memory
holds data, and a dedicated scratchpad data memory stores
stack and local variable information.
In addition, multiple L1 memory blocks are provided, offering a
configurable mix of SRAM and cache. The memory manage-
ment unit (MMU) provides memory protection for individual
tasks that may be operating on the core and can protect system
registers from unintended access.
• Microcontroller features, such as arbitrary bit and bit-field
manipulation, insertion, and extraction; integer operations
on 8-, 16-, and 32-bit data-types; and separate user and
supervisor stack pointers.
• Code density enhancements, which include intermixing of
16-bit and 32-bit instructions (no mode switching, no code
segregation). Frequently used instructions are encoded
in 16 bits.
PROCESSOR INFRASTRUCTURE
The following sections provide information on the primary
infrastructure components of the ADSP-BF70x processor.
The architecture provides three modes of operation: user mode,
supervisor mode, and emulation mode. User mode has
restricted access to certain system resources, thus providing a
protected software environment, while supervisor mode has
unrestricted access to the system and core resources.
DMA Controllers
The processor uses direct memory access (DMA) to transfer
data within memory spaces or between a memory space and a
peripheral. The processor can specify data transfer operations
and return to normal processing while the fully integrated DMA
controller carries out the data transfers independent of proces-
sor activity.
DMA transfers can occur between memory and a peripheral or
between one memory and another memory. Each memory-to-
memory DMA stream uses two channels, where one channel is
the source channel, and the second is the destination channel.
All DMAs can transport data to and from all on-chip and off-
chip memories. Programs can use two types of DMA transfers,
descriptor-based or register-based. Register-based DMA allows
the processor to directly program DMA control registers to ini-
tiate a DMA transfer. On completion, the control registers may
be automatically updated with their original setup values for
continuous transfer. Descriptor-based DMA transfers require a
set of parameters stored within memory to initiate a DMA
sequence. Descriptor-based DMA transfers allow multiple
DMA sequences to be chained together and a DMA channel can
be programmed to automatically set up and start another DMA
transfer after the current sequence completes.
INSTRUCTION SET DESCRIPTION
The Blackfin processor instruction set has been optimized so
that 16-bit opcodes represent the most frequently used instruc-
tions, resulting in excellent compiled code density. Complex
DSP instructions are encoded into 32-bit opcodes, representing
fully featured multifunction instructions. The Blackfin proces-
sor supports a limited multi-issue capability, where a 32-bit
instruction can be issued in parallel with two 16-bit instruc-
tions, allowing the programmer to use many of the core
resources in a single instruction cycle.
The Blackfin processor family assembly language instruction set
employs an algebraic syntax designed for ease of coding and
readability. The instructions have been specifically tuned to pro-
vide a flexible, densely encoded instruction set that compiles to
a very small final memory size. The instruction set also provides
fully featured multifunction instructions that allow the pro-
grammer to use many of the processor core resources in a single
instruction. Coupled with many features more often seen on
microcontrollers, this instruction set is very efficient when com-
piling C and C++ source code. In addition, the architecture
supports both user (algorithm/application code) and supervisor
(O/S kernel, device drivers, debuggers, ISRs) modes of opera-
tion, allowing multiple levels of access to core processor
resources.
The DMA controller supports the following DMA operations.
• A single linear buffer that stops on completion.
• A linear buffer with negative, positive, or zero stride length.
• A circular, auto-refreshing buffer that interrupts when each
buffer becomes full.

• A similar buffer that interrupts on fractional buffers (for
Trigger Routing Unit (TRU)
example, 1/2, 1/4).
The TRU provides system-level sequence control without core
intervention. The TRU maps trigger masters (generators of trig-
gers) to trigger slaves (receivers of triggers). Slave endpoints can
be configured to respond to triggers in various ways. Common
applications enabled by the TRU include:
• Automatically triggering the start of a DMA sequence after
a sequence from another DMA channel completes
• 1D DMA—uses a set of identical ping-pong buffers defined
by a linked ring of two-word descriptor sets, each contain-
ing a link pointer and an address.
• 1D DMA—uses a linked list of 4 word descriptor sets con-
taining a link pointer, an address, a length, and a
configuration.
• 2D DMA—uses an array of one-word descriptor sets, spec-
ifying only the base DMA address.
• 2D DMA—uses a linked list of multi-word descriptor sets,
specifying everything.
• Software triggering
• Synchronization of concurrent activities
General-Purpose I/O (GPIO)
Each general-purpose port pin can be individually controlled by
manipulation of the port control, status, and interrupt registers:
• GPIO direction control register—Specifies the direction of
each individual GPIO pin as input or output.
• GPIO control and status registers—A write one to modify
mechanism allows any combination of individual GPIO
pins to be modified in a single instruction, without affect-
ing the level of any other GPIO pins.
• GPIO interrupt mask registers—Allow each individual
GPIO pin to function as an interrupt to the processor.
GPIO pins defined as inputs can be configured to generate
hardware interrupts, while output pins can be triggered by
software interrupts.
Event Handling
The processor provides event handling that supports both nest-
ing and prioritization. Nesting allows multiple event service
routines to be active simultaneously. Prioritization ensures that
servicing of a higher-priority event takes precedence over ser-
vicing of a lower-priority event. The processor provides support
for five different types of events:
• Emulation—An emulation event causes the processor to
enter emulation mode, allowing command and control of
the processor through the JTAG interface.
• Reset—This event resets the processor.
• Nonmaskable interrupt (NMI)—The NMI event can be
generated either by the software watchdog timer, by the
NMI input signal to the processor, or by software. The
NMI event is frequently used as a power-down indicator to
initiate an orderly shutdown of the system.
• GPIO interrupt sensitivity registers—Specify whether indi-
vidual pins are level- or edge-sensitive and specify—if
edge-sensitive—whether just the rising edge or both the ris-
ing and falling edges of the signal are significant.
• Exceptions—Events that occur synchronously to program
flow (in other words, the exception is taken before the
instruction is allowed to complete). Conditions such as
data alignment violations and undefined instructions cause
exceptions.
• Interrupts —Events that occur asynchronously to program
flow. They are caused by input signals, timers, and other
peripherals, as well as by an explicit software instruction.
Pin Interrupts
Every port pin on the processor can request interrupts in either
an edge-sensitive or a level-sensitive manner with programma-
ble polarity. Interrupt functionality is decoupled from GPIO
operation. Three system-level interrupt channels (PINT0–3) are
reserved for this purpose. Each of these interrupt channels can
manage up to 32 interrupt pins. The assignment from pin to
interrupt is not performed on a pin-by-pin basis. Rather, groups
of eight pins (half ports) can be flexibly assigned to interrupt
channels.
Every pin interrupt channel features a special set of 32-bit mem-
ory-mapped registers that enable half-port assignment and
interrupt management. This includes masking, identification,
and clearing of requests. These registers also enable access to the
respective pin states and use of the interrupt latches, regardless
of whether the interrupt is masked or not. Most control registers
feature multiple MMR address entries to write-one-to-set or
write-one-to-clear them individually.
System Event Controller (SEC)
The SEC manages the enabling, prioritization, and routing of
events from each system interrupt or fault source. Additionally,
it provides notification and identification of the highest priority
active system interrupt request to the core and routes system
fault sources to its integrated fault management unit. The SEC
triggers core general-purpose interrupt IVG11. It is recom-
mended that IVG11 be set to allow self-nesting. The four lower
priority interrupts (IVG15-12) may be used for software
interrupts.
Pin Multiplexing
The processor supports a flexible multiplexing scheme that mul-
tiplexes the GPIO pins with various peripherals. A maximum of
4 peripherals plus GPIO functionality is shared by each GPIO
pin. All GPIO pins have a bypass path feature—that is, when the

active, the data signal before the pad driver is looped back to the
receive path for the same GPIO pin.

MEMORY ARCHITECTURE
The processor views memory as a single unified 4G byte address
space, using 32-bit addresses. All resources, including internal
memory, external memory, and I/O control registers, occupy
separate sections of this common address space. The memory
portions of this address space are arranged in a hierarchical
structure to provide a good cost/performance balance of some
very fast, low-latency core-accessible memory as cache or
SRAM, and larger, lower-cost and performance interface-acces-
sible memory systems. See Figure 3.

The core has its own private L1 memory. The modified Harvard
architecture supports two concurrent 32-bit data accesses along
with an instruction fetch at full processor speed which provides
high-bandwidth processor performance. In the core, a 64K byte
block of data memory partners with an 64K byte memory block
for instruction storage. Each data block is multibanked for effi-
cient data exchange through DMA and can be configured as
SRAM. Alternatively, 16K bytes of each block can be configured
in L1 cache mode. The four-way set-associative instruction
cache and the 2 two-way set-associative data caches greatly
accelerate memory access performance, especially when access-
ing external memories.

regardless of the size of the device used.
• AES in ECB, CBC, ICM, and CTR modes with 128-, 192-,
and 256-bit keys
• DES in ECB and CBC mode with 56-bit key
• 3DES in ECB and CBC mode with 3x 56-bit key
Dynamic Memory Controller (DMC)
The following hardware-accelerated hash functions are
supported:
• SHA-1
• SHA-2 with 224-bit and 256-bit digest
• HMAC transforms for SHA-1 and SHA-2
Public key accelerator is available to offload computation-inten-
sive public key cryptography operations.
Both a hardware-based nondeterministic random number gen-
erator and pseudo-random number generator are available. The
TRNG also provides HW post-processing to meet NIST
requirements of FIPS 140-2, while the PRNG is ANSI X9.31
compliant.
Secure boot is also available with 224-bit elliptic curve digital
signatures ensuring integrity and authenticity of the boot
stream. Optionally, confidentiality is also ensured through AES-
128 encryption.
The DMC includes a controller that supports JESD79-2E com-
patible double-data-rate (DDR2) SDRAM and JESD209A low-
power DDR (LPDDR) SDRAM devices. The DMC PHY fea-
tures on-die termination on all data and data strobe pins that
can be used during reads.
I/O Memory Space
The processor does not define a separate I/O space. All
resources are mapped through the flat 32-bit address space. On-
chip I/O devices have their control registers mapped into mem-
ory-mapped registers (MMRs) at addresses in a region of the
4G byte address space. These are separated into two smaller
blocks, one which contains the control MMRs for all core func-
tions, and the other which contains the registers needed for
setup and control of the on-chip peripherals outside of the core.
The MMRs are accessible only in supervisor mode and appear
as reserved space to on-chip peripherals.
Booting
The processor has several mechanisms for automatically loading
internal and external memory after a reset. The boot mode is
defined by the SYS_BMODE input pins dedicated for this pur-
pose. There are two categories of boot modes. In master boot
mode, the processor actively loads data from serial memories. In
slave boot modes, the processor receives data from external host
devices.
The boot modes are shown in Table 2. These modes are imple-
mented by the SYS_BMODE bits of the reset configuration
register and are sampled during power-on resets and software-
initiated resets.
CAUTION
This product includes security features that can be
used to protect embedded nonvolatile memory
contents and prevent execution of unauthorized
code. When security is enabled on this device
(either by the ordering party or the subsequent
receiving parties), the ability of Analog Devices to
conduct failure analysis on returned devices is
limited. Contact Analog Devices for details on the
failure analysis limitations for this device.
Secure debug is also employed to allow only trusted users to
access the system with debug tools.

Multi-Parity-Bit-Protected L1 Memories
In the processor’s L1 memory space, whether SRAM or cache,
each word is protected by multiple parity bits to detect the single
event upsets that occur in all RAMs. This applies both to L1
instruction and data memory spaces.
SECURITY FEATURES
The ADSP-BF70x processor supports standards-based hard-
ware-accelerated encryption, decryption, authentication, and
true random number generation.
ECC-Protected L2 Memories
Error correcting codes (ECC) are used to correct single event
upsets. The L2 memory is protected with a single error correct-
double error detect (SEC-DED) code. By default ECC is
enabled, but it can be disabled on a per-bank basis. Single-bit
errors are transparently corrected. Dual-bit errors can issue a

system event or fault if enabled. ECC protection is fully trans-
parent to the user, even if L2 memory is read or written by 8-bit
or 16-bit entities.
Watchdog
The on-chip software watchdog timer can supervise the
Blackfin+ core.
CRC-Protected Memories
Bandwidth Monitor
While parity bit and ECC protection mainly protect against ran-
dom soft errors in L1 and L2 memory cells, the CRC engines can
be used to protect against systematic errors (pointer errors) and
static content (instruction code) of L1, L2, and even L3 memo-
ries (DDR2, LPDDR). The processor features two CRC engines
which are embedded in the memory-to-memory DMA
Memory-to-memory DMA channels are equipped with a band-
width monitor mechanism. They can signal a system event or
fault when transactions tend to starve because system buses are
fully loaded with higher-priority traffic.
Signal Watchdogs
controllers. CRC checksums can be calculated or compared on
the fly during memory transfers, or one or multiple memory
regions can be continuously scrubbed by a single DMA work
unit as per DMA descriptor chain instructions. The CRC engine
also protects data loaded during the boot process.
The eight general-purpose timers feature modes to monitor off-
chip signals. The watchdog period mode monitors whether
external signals toggle with a period within an expected range.
The watchdog width mode monitors whether the pulse widths
of external signals are within an expected range. Both modes
help to detect undesired toggling (or lack thereof) of
system-level signals.
Memory Protection
The Blackfin+ core features a memory protection concept,
which grants data and/or instruction accesses to enabled mem-
ory regions only. A supervisor mode vs. user mode
programming model supports dynamically varying access
rights. Increased flexibility in memory page size options sup-
ports a simple method of static memory partitioning.
Up/Down Count Mismatch Detection
The GP counter can monitor external signal pairs, such as
request/grant strobes. If the edge count mismatch exceeds the
expected range, the GP counter can flag this to the processor or
to the fault management unit of the SEC.
System Protection
Fault Management
The system protection unit (SPU) guards against accidental or
unwanted access to the MMR space of a peripheral by providing
a write-protection mechanism. The user is able to choose and
configure the peripherals that are protected as well as configure
which ones of the four system MMR masters (core, memory
DMA, the SPI host port, and Coresight debug) the peripherals
are guarded against.
The SPU is also part of the security infrastructure. Along with
providing write-protection functionality, the SPU is employed
to define which resources in the system are secure or non-secure
and to block access to secure resources from non-secure
masters.
The fault management unit is part of the system event controller
(SEC). Any system event, whether a dual-bit uncorrectable ECC
error, or any peripheral status interrupt, can be defined as being
a fault. Additionally, the system events can be defined as an
interrupt to the core. If defined as such, the SEC forwards the
event to the fault management unit, which may automatically
reset the entire device for reboot, or simply toggle the
SYS_FAULT output pin to signal off-chip hardware. Optionally,
the fault management unit can delay the action taken through a
keyed sequence, to provide a final chance for the Blackfin+ core
to resolve the issue and to prevent the fault action from being
taken.
Synonymously, the system memory protection unit (SMPU)
provides memory protection against read and/or write transac-
tions to defined regions of memory. There are two SMPU units
in the ADSP-BF70x processors. One is for the L2 memory and
the other is for the external DDR memory.
The SMPU is also part of the security infrastructure. It allows
the user to not only protect against arbitrary read and/or write
transactions, but it also allows regions of memory to be defined
as secure and prevent non-secure masters from accessing those
memory regions.
ADDITIONAL PROCESSOR PERIPHERALS
The processor contains a rich set of peripherals connected to the
core through several high-bandwidth buses, providing flexibility
in system configuration as well as excellent overall system per-
formance (see the block diagram on Page 1). The processor
contains high-speed serial and parallel ports, an interrupt con-
troller for flexible management of interrupts from the on-chip
peripherals or external sources, and power management control
functions to tailor the performance and power characteristics of
the processor and system to many application scenarios.
Watchpoint Protection
The following sections describe additional peripherals that were
not previously described.
The primary purpose of watchpoints and hardware breakpoints
is to serve emulator needs. When enabled, they signal an emula-
tor event whenever user-defined system resources are accessed
or the core executes from user-defined addresses. Watchpoint
events can be configured such that they signal the events to the
fault management unit of the SEC.
Timers
The processor includes several timers which are described in the
following sections.

General-Purpose Timers
configuration, one SPORT provides two transmit signals while
the other SPORT provides the two receive signals. The frame
sync and clock are shared.
There is one GP timer unit, and it provides eight general-pur-
pose programmable timers. Each timer has an external pin that
can be configured either as a pulse width modulator (PWM) or
timer output, as an input to clock the timer, or as a mechanism
for measuring pulse widths and periods of external events.
These timers can be synchronized to an external clock input on
the TIMER_TMRx pins, an external TIMER_CLK input pin, or
to the internal SCLK0.
These timer units can be used in conjunction with the UARTs
and the CAN controller to measure the width of the pulses in
the data stream to provide a software auto-baud detect function
for the respective serial channels.
Serial ports operate in six modes:
• Standard DSP serial mode
• Multichannel (TDM) mode
• I2S mode
• Packed I2S mode
• Left-justified mode
• Right-justified mode
General-Purpose Counters
The GP timers can generate interrupts to the processor core,
providing periodic events for synchronization to either the sys-
tem clock or to external signals. Timer events can also trigger
other peripherals through the TRU (for instance, to signal a
fault). Each timer may also be started and/or stopped by any
TRU master without core intervention.
A 32-bit counter is provided that can operate in general-pur-
pose up/down count modes and can sense 2-bit quadrature or
binary codes as typically emitted by industrial drives or manual
thumbwheels. Count direction is either controlled by a level-
sensitive input pin or by two edge detectors.
A third counter input can provide flexible zero marker support
and can alternatively be used to input the push-button signal of
thumbwheel devices. All three pins have a programmable
debouncing circuit.
Internal signals forwarded to a GP timer enable this timer to
measure the intervals between count events. Boundary registers
enable auto-zero operation or simple system warning by inter-
rupts when programmed count values are exceeded.
Core Timer
The processor core also has its own dedicated timer. This extra
timer is clocked by the internal processor clock and is typically
used as a system tick clock for generating periodic operating
system interrupts.
Watchdog Timer
The core includes a 32-bit timer, which may be used to imple-
ment a software watchdog function. A software watchdog can
improve system availability by forcing the processor to a known
state, through generation of a hardware reset, nonmaskable
interrupt (NMI), or general-purpose interrupt, if the timer
expires before being reset by software. The programmer initial-
izes the count value of the timer, enables the appropriate
interrupt, then enables the timer. Thereafter, the software must
reload the counter before it counts down to zero from the pro-
grammed value. This protects the system from remaining in an
unknown state where software that would normally reset the
timer has stopped running due to an external noise condition or
software error.
Parallel Peripheral Interface (PPI)
The processor provides a parallel peripheral interface (PPI) that
supports data widths up to 18 bits. The PPI supports direct con-
nection to TFT LCD panels, parallel analog-to-digital and
digital-to-analog converters, video encoders and decoders,
image sensor modules, and other general-purpose peripherals.
The following features are supported in the PPI module:
• Programmable data length: 8 bits, 10 bits, 12 bits, 14 bits,
16 bits, and 18 bits per clock.
• Various framed, non-framed, and general-purpose operat-
ing modes. Frame syncs can be generated internally or can
be supplied by an external device.
• ITU-656 status word error detection and correction for
ITU-656 receive modes and ITU-656 preamble and status
word decode.
After a reset, software can determine if the watchdog was the
source of the hardware reset by interrogating a status bit in its
timer control register that is set only upon a watchdog-gener-
ated reset.
Serial Ports (SPORTs)
• Optional packing and unpacking of data to/from 32 bits
from/to 8 bits, 16 bits and 24 bits. If packing/unpacking is
enabled, endianness can be configured to change the order
of packing/unpacking of bytes/words.
• RGB888 can be converted to RGB666 or RGB565 for trans-
mit modes.
• Various de-interleaving/interleaving modes for receiv-
ing/transmitting 4:2:2 YCrCb data.
• Configurable LCD data enable (DEN) output available on
Frame Sync 3.
Two synchronous serial ports (comprised of four half-SPORTs)
provide an inexpensive interface to a wide variety of digital and
mixed-signal peripheral devices such as Analog Devices’ audio
codecs, ADCs, and DACs. Each half-SPORT is made up of two
data lines, a clock, and frame sync. The data lines can be pro-
grammed to either transmit or receive and each data line has a
dedicated DMA channel.
Serial port data can be automatically transferred to and from
on-chip memory/external memory through dedicated DMA
channels. Each of the serial ports can work in conjunction with
another serial port to provide TDM support. In this

The UART ports support automatic hardware flow control

Serial Peripheral Interface (SPI) Ports
The processors have three industry-standard SPI-compatible
ports that allow it to communicate with multiple SPI-compati-
ble devices.
output with programmable assertion FIFO levels.
To help support the local interconnect network (LIN) protocols,
a special command causes the transmitter to queue a break
command of programmable bit length into the transmit buffer.
Similarly, the number of stop bits can be extended by a pro-
grammable inter-frame space.
The baseline SPI peripheral is a synchronous, four-wire inter-
face consisting of two data pins, one device select pin, and a
gated clock pin. The two data pins allow full-duplex operation
to other SPI-compatible devices. An additional two (optional)
data pins are provided to support quad SPI operation. Enhanced
modes of operation such as flow control, fast mode, and dual
I/O mode (DIOM) are also supported. In addition, a direct
memory access (DMA) mode allows for transferring several
words with minimal CPU interaction.
The capabilities of the UARTs are further extended with sup-
port for the Infrared Data Association (IrDA®) serial infrared
physical layer link specification (SIR) protocol.
2-Wire Controller Interface (TWI)
The processor includes a 2-wire interface (TWI) module for
providing a simple exchange method of control data between
multiple devices. The TWI module is compatible with the
widely used I2C bus standard. The TWI module offers the
capabilities of simultaneous master and slave operation and
support for both 7-bit addressing and multimedia data arbitra-
tion. The TWI interface utilizes two pins for transferring clock
(TWI_SCL) and data (TWI_SDA) and supports the protocol at
speeds up to 400k bits/sec. The TWI interface pins are compati-
ble with 5 V logic levels.
With a range of configurable options, the SPI ports provide a
glueless hardware interface with other SPI-compatible devices
in master mode, slave mode, and multimaster environments.
The SPI peripheral includes programmable baud rates, clock
phase, and clock polarity. The peripheral can operate in a multi-
master environment by interfacing with several other devices,
acting as either a master device or a slave device. In a multimas-
ter environment, the SPI peripheral uses open-drain outputs to
avoid data bus contention. The flow control features enable slow
slave devices to interface with fast master devices by providing
an SPI Ready pin which flexibly controls the transfers.
Additionally, the TWI module is fully compatible with serial
camera control bus (SCCB) functionality for easier control of
various CMOS camera sensor devices.
The SPI port’s baud rate and clock phase/polarities are pro-
grammable, and it has integrated DMA channels for both
transmit and receive data streams.
Mobile Storage Interface (MSI)
SPI Host Port (SPIHP)
The mobile storage interface (MSI) controller acts as the host
interface for multimedia cards (MMC), secure digital memory
cards (SD), and secure digital input/output cards (SDIO). The
following list describes the main features of the MSI controller:
• Support for a single MMC, SD memory, and SDIO card
• Support for 1-bit and 4-bit SD modes
• Support for 1-bit, 4-bit, and 8-bit MMC modes
• Support for eMMC 4.5 embedded NAND flash devices
• Support for power management and clock control
The processor includes one SPI host port which may be used in
conjunction with any available SPI port to enhance its SPI slave
mode capabilities. The SPIHP allows a SPI host device access to
memory-mapped resources of the processor through a SPI
SRAM/FLASH style protocol. The following features are
included:
• Direct read/write of memory and memory-mapped
registers
• Support for pre-fetch for faster reads
• An eleven-signal external interface with clock, command,
optional interrupt, and up to eight data lines
• Support for SPI controllers that implement hardware-
based SPI memory protocol
• Card interface clock generation from SCLK0 or SCLK1
• SDIO interrupt and read wait features
• Error capture and reporting for protocol errors, bus errors,
and over/underflow
UART Ports
Controller Area Network (CAN)
The processor provides two full-duplex universal asynchronous
receiver/transmitter (UART) ports, which are fully compatible
with PC-standard UARTs. Each UART port provides a simpli-
fied UART interface to other peripherals or hosts, supporting
full-duplex, DMA-supported, asynchronous transfers of serial
data. A UART port includes support for five to eight data bits,
and none, even, or odd parity. Optionally, an additional address
bit can be transferred to interrupt only addressed nodes in
multi-drop bus (MDB) systems. A frame is terminated by a con-
figurable number of stop bits.
A CAN controller implements the CAN 2.0B (active) protocol.
This protocol is an asynchronous communications protocol
used in both industrial and automotive control systems. The
CAN protocol is well suited for control applications due to its
capability to communicate reliably over a network. This is
because the protocol incorporates CRC checking, message error
tracking, and fault node confinement.

The CAN controller offers the following features:
• 32 mailboxes (8 receive only, 8 transmit only, 16 configu-
rable for receive or transmit)
• Dedicated acceptance masks for each mailbox
• Additional data filtering on first two bytes
• Support for both the standard (11-bit) and extended
(29-bit) identifier (ID) message formats
• Support for remote frames
• Active or passive network support
• CAN wake-up from hibernation mode (lowest static power
consumption mode)
• Interrupts, including: TX complete, RX complete, error
and global
An additional crystal is not required to supply the CAN clock, as
the CAN clock is derived from a system clock through a pro-
grammable divider.
• Auto sequencing capability with up to 4 autoconversions in
a single session. Each conversion can be programmed to
select any input channel.
• Four data registers (individually addressable) to store con-
version values
System Crossbars (SCB)
The system crossbars (SCB) are the fundamental building
blocks of a switch-fabric style for (on-chip) system bus inter-
connection. The SCBs connect system bus masters to system
bus slaves, providing concurrent data transfer between multiple
bus masters and multiple bus slaves. A hierarchical model—
built from multiple SCBs—provides a power and area efficient
system interconnect, which satisfies the performance and flexi-
bility requirements of a specific system.
The SCBs provide the following features:
• Highly efficient, pipelined bus transfer protocol for sus-
tained throughput
• Full-duplex bus operation for flexibility and reduced
latency
USB 2.0 On-the-Go Dual-Role Device Controller
The USB 2.0 on-the-go (OTG) dual-role device controller pro-
vides a low-cost connectivity solution for the growing adoption
of this bus standard in industrial applications, as well as con-
sumer mobile devices such as cell phones, digital still cameras,
and MP3 players. The USB 2.0 controller allows these devices to
transfer data using a point-to-point USB connection without
the need for a PC host. The module can operate in a traditional
USB peripheral-only mode as well as the host mode presented
in the OTG supplement to the USB 2.0 specification.
The USB clock is provided through a dedicated external crystal
or crystal oscillator.
The USB OTG dual-role device controller includes a phase
locked loop with programmable multipliers to generate the nec-
essary internal clocking frequency for USB.
• Concurrent bus transfer support to allow multiple bus
masters to access bus slaves simultaneously
• Protection model (privileged/secure) support for selective
bus interconnect protection
POWER AND CLOCK MANAGEMENT
The processor provides three operating modes, each with a dif-
ferent performance/power profile. Control of clocking to each
of the processor peripherals also reduces power consumption.
See Table 5 for a summary of the power settings for each mode.
System Crystal Oscillator and USB Crystal Oscillator
The processor can be clocked by an external crystal (see
Figure 4), a sine wave input, or a buffered, shaped clock derived
from an external clock oscillator. If an external clock is used, it
should be a TTL compatible signal and must not be halted,
changed, or operated below the specified frequency during nor-
mal operation. This signal is connected to the SYS_CLKIN pin
of the processor. When an external clock is used, the SYS_XTAL
pin must be left unconnected. Alternatively, because the proces-
sor includes an on-chip oscillator circuit, an external crystal
may be used.
For fundamental frequency operation, use the circuit shown in
Figure 4. A parallel-resonant, fundamental frequency, micro-
processor grade crystal is connected across the SYS_CLKIN and
SYS_XTAL pins. The on-chip resistance between SYS_CLKIN
and the SYS_XTAL pin is in the 500 kΩ range. Further parallel
resistors are typically not recommended.
Housekeeping ADC (HADC)
The HADC provides a general-purpose, multichannel succes-
sive approximation analog-to-digital converter. It supports the
following features:
• 12-bit ADC core (10-bit accuracy) with built-in sample and
hold
• 4 single-ended input channels
• Throughput rates up to 1 MSPS
• Single external reference with analog inputs between 0 V
and 3.3 V
• Selectable ADC clock frequency including the ability to
program a prescaler
The two capacitors and the series resistor shown in Figure 4
fine-tune phase and amplitude of the sine frequency. The capac-
itor and resistor values shown in Figure 4 are typical values
only. The capacitor values are dependent upon the load capaci-
tance recommendations of the crystal manufacturer and the
PCB physical layout. The resistor value depends on the drive
• Adaptable conversion type: allows single or continuous
conversion with option of autoscan

The clock generation unit (CGU) generates all on-chip clocks
and synchronization signals. Multiplication factors are pro-
grammed to define the PLLCLK frequency. Programmable
values divide the PLLCLK frequency to generate the core clock
(CCLK), the system clocks (SYSCLK, SCLK0, and SCLK1), the
LPDDR or DDR2 clock (DCLK), and the output clock (OCLK).
Writing to the CGU control registers does not affect the behav-
ior of the PLL immediately. Registers are first programmed with
a new value, and the PLL logic executes the changes so that it
transitions smoothly from the current conditions to the new
ones.
Figure 4. External Crystal Connection
A third-overtone crystal can be used for frequencies above
25 MHz. The circuit is then modified to ensure crystal operation
only at the third overtone by adding a tuned inductor circuit as
shown in Figure 4. A design procedure for third-overtone oper-
ation is discussed in detail in application note (EE-168) Using
Third Overtone Crystals with the ADSP-218x DSP (www.ana-
log.com/ee-168).
SYS_CLKIN oscillations start when power is applied to the
VDD_EXT pins. The rising edge of SYS_HWRST can be
applied after all voltage supplies are within specifications, and
SYS_CLKIN oscillations are stable.
The same recommendations may be used for the USB crystal
oscillator.
Real-Time Clock
The real-time clock (RTC) provides a robust set of digital watch
features, including current time, stopwatch, and alarm. The
RTC is clocked by a 32.768 kHz crystal external to the processor.
Connect RTC pins RTC_CLKIN and RTC_XTAL with external
components as shown in Figure 5.
The RTC peripheral has dedicated power supply pins so that it
can remain powered up and clocked even when the rest of the
processor is in a low power state. The RTC provides several pro-
grammable interrupt options, including interrupt per second,
minute, hour, or day clock ticks, interrupt on programmable
stopwatch countdown, or interrupt at a programmed alarm
time.
Clock Out/External Clock
The SYS_CLKOUT output pin has programmable options to
output divided-down versions of the on-chip clocks. By default,
the SYS_CLKOUT pin drives a buffered version of the SYS_
CLKIN input. Clock generation faults (for example, PLL
unlock) may trigger a reset by hardware. The clocks shown in
Table 3 can be output on the SYS_CLKOUT pin.
The 32.768 kHz input clock frequency is divided down to a 1 Hz
signal by a prescaler. The counter function of the timer consists
of four counters: a 60-second counter, a 60-minute counter, a
24-hour counter, and a 32,768-day counter. When the alarm
interrupt is enabled, the alarm function generates an interrupt
when the output of the timer matches the programmed value in
the alarm control register. There are two alarms. The first alarm
is for a time of day. The second alarm is for a specific day and
time of that day.

As shown in Table 4, the processor supports multiple power
domains, which maximizes flexibility while maintaining com-
pliance with industry standards and conventions. There are no
sequencing requirements for the various power domains, but all
domains must be powered according to the appropriate Specifi-
cations table for processor operating conditions; even if the
feature/peripheral is not used.
Hibernate State—Maximum Static Power Savings
The hibernate state maximizes static power savings by disabling
the voltage and clocks to the processor core and to all of the
peripherals. This setting signals the external voltage regulator
supplying the VDD_INT pins to shut off using the SYS_
EXTWAKE signal, which provides the lowest static power
dissipation.
Any critical information stored internally (for example, mem-
ory contents, register contents, and other information) must be
written to a nonvolatile storage device (or self-refreshed
DRAM) prior to removing power if the processor state is to be
preserved.

Because the VDD_EXT pins can still be supplied in this mode, all of

allows other devices that may be connected to the processor to
still have power applied without drawing unwanted current.

Reset Control Unit
The dynamic power management feature of the processor
allows the processor’s core clock frequency (fCCLK) to be dynam-
ically controlled.
The power dissipated by a processor is largely a function of its
clock frequency and the square of the operating voltage. For
example, reducing the clock frequency by 25% results in a 25%
reduction in dynamic power dissipation.
Reset is the initial state of the whole processor or the core and is
the result of a hardware- or software-triggered event. In this
state, all control registers are set to their default values and func-
tional units are idle. Exiting a full system reset starts with the
core being ready to boot.
The reset control unit (RCU) controls how all the functional
units enter and exit reset. Differences in functional require-
ments and clocking constraints define how reset signals are
generated. Programs must guarantee that none of the reset
functions puts the system into an undefined state or causes
resources to stall. This is particularly important when the core is
reset (programs must ensure that there is no pending system
activity involving the core when it is being reset).
See Table 5 for a summary of the power settings for each mode.
Full-On Operating Mode—Maximum Performance
In the full-on mode, the PLL is enabled and is not bypassed,
providing capability for maximum operational frequency. This
is the power-up default execution state in which maximum per-
formance can be achieved. The processor core and all enabled
peripherals run at full speed.
From a system perspective, reset is defined by both the reset tar-
get and the reset source described as follows in the following list.

available software add-ins to support real time operating sys-
tems, file systems, TCP/IP stacks, USB stacks, algorithmic
software modules, and evaluation hardware board support
packages. For more information, visit www.analog.com/cces.
EZ-KIT Lite Evaluation Board
Voltage Regulation
For processor evaluation, Analog Devices provides a wide range
of EZ-KIT Lite® evaluation boards. Including the processor and
key peripherals, the evaluation board also supports on-chip
emulation capabilities and other evaluation and development
features. Also available are various EZ-Extenders®, which are
daughter cards delivering additional specialized functionality,
including audio and video processing. For more information,
visit www.analog.com and search on “ezkit” or “ezextender”.
The processor requires an external voltage regulator to power
the VDD_INT pins. To reduce standby power consumption, the
external voltage regulator can be signaled through
SYS_EXTWAKE to remove power from the processor core.
This signal is high-true for power-up and may be connected
directly to the low-true shut-down input of many common
regulators.
While in the hibernate state, all external supply pins (VDD_
EXT, VDD_USB, and VDD_DMC) can still be powered, elimi-
nating the need for external buffers. The external voltage
regulator can be activated from this power down state by assert-
ing the SYS_HWRST pin, which then initiates a boot sequence.
SYS_EXTWAKE indicates a wake-up to the external voltage
regulator.
EZ-KIT Lite Evaluation Kits
For a cost-effective way to learn more about developing with
Analog Devices processors, Analog Devices offer a range of EZ-
KIT Lite evaluation kits. Each evaluation kit includes an EZ-KIT
Lite evaluation board, directions for downloading an evaluation
version of the available IDE, a USB cable, and a power supply.
The USB controller on the EZ-KIT Lite board connects to the
USB port of the user’s PC, enabling the chosen IDE evaluation
suite to emulate the on-board processor in-circuit. This permits
the customer to download, execute, and debug programs for the
EZ-KIT Lite system. It also supports in-circuit programming of
the on-board Flash device to store user-specific boot code,
enabling standalone operation. With the full version of Cross-
Core Embedded Studio installed (sold separately), engineers can
develop software for supported EZ-KITs or any custom system
utilizing supported Analog Devices processors.
SYSTEM DEBUG
The processor includes various features that allow for easy sys-
tem debug. These are described in the following sections.
System Watchpoint Unit
The system watchpoint unit (SWU) is a single module which
connects to a single system bus and provides for transaction
monitoring. One SWU is attached to the bus going to each
system slave. The SWU provides ports for all system bus address
channel signals. Each SWU contains four match groups of regis-
ters with associated hardware. These four SWU match groups
operate independently, but share common event (interrupt,
trigger, and others) outputs.
ADSP-BF706 EZ-KIT Mini
TM
The ADSP-BF706 EZ-KIT Mini product (ADZS-BF706-
EZMini) contains the ADSP-BF706 processor and is shipped
with all of the necessary hardware. Users can start their evalua-
tion immediately. The EZ-KIT Mini product includes the
standalone evaluation board and USB cable. The EZ-KIT Mini
ships with an on-board debug agent.
Debug Access Port
The debug access port (DAP) provides IEEE-1149.1 JTAG
interface support through its JTAG debug and serial wire debug
port (SWJ-DP). SWJ-DP is a combined JTAG-DP and SW-DP
that enables either serial wire debug (SWD) or a JTAG emulator
to be connected to a target. SWD signals share the same pins as
The evaluation board is designed to be used in conjunction with
the CrossCore Embedded Studio (CCES) development tools to
test capabilities of the ADSP-BF706 Blackfin processor.

registers. The emulators require the target board to include a
Blackfin Low Power Imaging Platform (BLIP)
header(s) that supports connection of the processor’s DAP to
the emulator for trace and debug.
The Blackfin low power imaging platform (BLIP) integrates the
ADSP-BF707 Blackfin processor and Analog Devices software
code libraries. The code libraries are optimized to detect the
presence and behavior of humans or vehicles in indoor and out-
door environments. The BLIP hardware platform is delivered
preloaded with the occupancy software module.
Analog Devices emulators actively drive JTG_TRST high.
Third-party emulators may expect a pull-up on JTG_TRST and
therefore will not drive JTG_TRST high. When using this type
of third-party emulator JTG_TRST must still be driven low
during power-up reset, but should subsequently be driven high
externally before any emulation or boundary-scan operations.
See Power-Up Reset Timing on Page 61 for more information
on POR specifications.
For more details on target board design issues including
mechanical layout, single processor connections, signal buffer-
ing, signal termination, and emulator pod logic, contact the
factory for more information.
Software Add-Ins for CrossCore Embedded Studio
Analog Devices offers software add-ins which seamlessly inte-
grate with CrossCore Embedded Studio to extend its capabilities
and reduce development time. Add-ins include board support
packages for evaluation hardware, various middleware pack-
ages, and algorithmic modules. Documentation, help,

RELATED SIGNAL CHAINS
A signal chain is a series of signal-conditioning electronic com-
ponents that receive input (data acquired from sampling either
real-time phenomena or from stored data) in tandem, with the
output of one portion of the chain supplying input to the next.
Signal chains are often used in signal processing applications to
gather and process data or to apply system controls based on
analysis of real-time phenomena.

12 mm × 12 mm 88-LEAD LFCSP (QFN) SIGNAL DESCRIPTIONS
The processor’s pin definitions are shown in Table 11. The col-
• General-Purpose Port: The Port column in the table shows
whether or not the signal is multiplexed with other signals
on a general-purpose I/O port pin.
• Pin Name: The Pin Name column in the table identifies the
name of the package pin (at power on reset) on which the
signal is located (if a single function pin) or is multiplexed
(if a general-purpose I/O pin).
umns in this table provide the following information:
• Signal Name: The Signal Name column in the table
includes the signal name for every pin and (where applica-
ble) the GPIO multiplexed pin function for every pin.
• Description: The Description column in the table provides
a verbose (descriptive) name for the signal.

ADSP-BF700/701/702/703/704/705/706/707
ADSP-BF70x DESIGNER QUICK REFERENCE
Table 15 provides a quick reference summary of pin related
information for circuit board design. The columns in this table
provide the following information:
• Power Domain: The Power Domain column in the table
specifies the power supply domain in which the signal
resides.
• Signal Name: The Signal Name column in the table
includes the signal name for every pin and (where applica-
ble) the GPIO multiplexed pin function for every pin.
• Pin Type: The Type column in the table identifies the I/O
type or supply type of the pin. The abbreviations used in
this column are na (none), I/O (input/output), a (analog), s
(supply), and g (ground).
• Driver Type: The Driver Type column in the table identi-
fies the driver type used by the pin. The driver types are
defined in the output drive currents section of this data
sheet.
• Internal Termination: The Int Term column in the table
specifies the termination present when the processor is not
in the reset or hibernate state. The abbreviations used in
this column are wk (weak keeper, weakly retains previous
value driven on the pin), pu (pull-up), or pd (pull-down).
• Reset Termination: The Reset Term column in the table
specifies the termination present when the processor is in
the reset state. The abbreviations used in this column are
wk (weak keeper, weakly retains previous value driven on
the pin), pu (pull-up), or pd (pull-down).
• Reset Drive: The Reset Drive column in the table specifies
the active drive on the signal when the processor is in the
reset state.
• Hibernate Termination: The Hiber Term column in the
table specifies the termination present when the processor
is in the hibernate state. The abbreviations used in this col-
umn are wk (weak keeper, weakly retains previous value
driven on the pin), pu (pull-up), or pd (pull-down).
• Hibernate Drive: The Hiber Drive column in the table
specifies the active drive on the signal when the processor is
in the hibernate state.
• Description and Notes: The Description and Notes column
in the table identifies any special requirements or charac-
teristics for the signal. If no special requirements are listed
the signal may be left unconnected if it is not used. Also, for
multiplexed general-purpose I/O pins, this column identi-
fies the functions available on the pin.
If an external pull-up or pull-down resistor is required for any
signal, 100 kΩ is the maximum value that can be used unless
otherwise noted.
Note that for Port A, Port B, and Port C (PA_00 to PC_14),
when SYS_HWRST is low, these pads are three-state. After
SYS_HWRST is released, but before code execution begins,
these pins are internally pulled up. Subsequently, the state
depends on the input enable and output enable which are
controlled by software.
Software control of internal pull-ups works according to the
following settings in the PADS_PCFG0 register. When
PADS_PCFG0 = 0: For PA_15:PA_00, PB_15:PB_00, and
PC_14:PC_00, the internal pull-up is enabled when both the
input enable and output enable of a particular pin are
deasserted. When PADS_PCFG0 = 1: For PA_15:PA_00,
PB_15:PB_00, and PC_14:PC_00, the internal pull-up is
enabled as long as the output enable of a particular pin is
deasserted.
There are some exceptions to this scheme:
• Internal pull-ups are always disabled if MSI mode is
selected for that signal.
• The following signals enabled the internal pull-down when
the output enable is de-asserted: SMC0_AMS[1:0],
SMC0_ARE, SMC0_AWE, SMC0_AOE, SMC0_ARDY,
SPI0_SEL[6:1], SPI1_SEL[4:1], and SPI2_SEL[3:1].

1 SYS_CLKOUT jitter is dependent on the application system design including pin switching activity, board layout, and the jitter characteristics of the SYS_CLKIN source. Due
to the dependency on these factors the measured jitter may be higher or lower than this typical specification for each end application.
2 The value in the Typ field is the percentage of the SYS_CLKOUT period.
3 The maximum achievable frequency for any peripheral in external clock mode is dependent on being able to meet the setup and hold times in the ac timing specifications
section for that peripheral. Pay particular attention to setup and hold times for VDD_EXT = 1.8 V which may preclude the maximum frequency listed here.
4 The peripheral external clock frequency must also be less than or equal to the fSCLK that clocks the peripheral.

Clock Current
Total Internal Power Dissipation
The dynamic clock currents provide the total power dissipated
by all transistors switching in the clock paths. The power dissi-
pated by each clock domain is dependent on voltage (VDD_INT),
operating frequency and a unique scaling factor.
Total power dissipation has two components:
1. Static, including leakage current (deep sleep)
2. Dynamic, due to transistor switching characteristics for
each clock domain
Many operating conditions can also affect power dissipation,
including temperature, voltage, operating frequency, and pro-
cessor activity. The following equation describes the internal
current consumption.

DDINT_PLLCLK_DYN (mA) = 0.012 × fPLLCLK (MHz) × VDD_INT (V)
DDINT_SYSCLK_DYN (mA) = 0.120 × fSYSCLK (MHz) × VDD_INT (V)
DDINT_SCLK0_DYN (mA) = 0.110 × fSCLK0 (MHz) × VDD_INT (V)
DDINT_SCLK1_DYN (mA) = 0.068 × fSCLK1 (MHz) × VDD_INT (V)
DDINT_DCLK_DYN (mA) = 0.055 × fDCLK (MHz) × VDD_INT (V)

The dynamic component of the USB clock is a unique case. The
USB clock contributes a near constant current value when used.
IDDINT_USBCLK_DYN
Table 20. IDDINT_USBCLK_DYN Current
IDDINT_DEEPSLEEP is the only item present that is part of the static
power dissipation component. IDDINT_DEEPSLEEP is specified as a
function of voltage (VDD_INT) and temperature (see Table 21).
There are eight different items that contribute to the dynamic
power dissipation. These components fall into three broad cate-
gories: application-dependent currents, clock currents, and data
transmission currents.

Application-Dependent Current
The application-dependent currents include the dynamic cur-
rent in the core clock domain.
Core clock (CCLK) use is subject to an activity scaling factor
(ASF) that represents application code running on the processor
cores and L1/L2 memories (Table 22). The ASF is combined
with the CCLK frequency and VDD_INT dependent data in
Table 23 to calculate this portion.
Data Transmission Current
The data transmission current represents the power dissipated
when transmitting data. This current is expressed in terms of
data rate. The calculation is performed by adding the data rate
(MB/s) of each DMA-driven access to peripherals, L1, L2, and
external memory. This number is then multiplied by a weighted
data-rate coefficient and VDD_INT
DDINT_DMADR_DYN (mA) = Weighted DRC × Total Data Rate
(MB/s) × VDD_INT (V)
:
I
I
DDINT_CCLK_DYN (mA) = Table 23 × ASF
A weighted data-rate coefficient is used because different coeffi-
cients exist depending on the source and destination of the
transfer. For details on using this equation and calculating the
weighted DRC, see the related Engineer Zone material. For a
quick maximum calculation, the weighted DRC can be assumed
to be 0.0497, which is the coefficient for L1 to L1 transfers.

TIMING SPECIFICATIONS
Specifications are subject to change without notice.
Clock and Reset Timing
Table 29 and Figure 8 describe clock and reset operations related to the clock generation unit (CGU). Per the CCLK, SYSCLK, SCLK0,
SCLK1, DCLK, and OCLK timing specifications in Table 17 on Page 51 and Table 18 on Page 52, combinations of SYS_CLKIN and clock
multipliers must not select clock rates in excess of the processor’s maximum instruction rate.

Power-Up Reset Timing
A power-up reset is required to place the processor in a known state after power-up. A power-up reset is initiated by asserting
SYS_HWRST and JTG_TRST. During power-up reset, all pins are high impedance except for those noted in the ADSP-BF70x Designer
Quick Reference on Page 38.
Both JTG_TRST and SYS_HWRST need to be asserted upon power-up, but only SYS_HWRST needs to be released for the device to boot
properly. JTG_TRST may be asserted indefinitely for normal operation. JTG_TRST only needs to be released when using an emulator to
connect to the DAP for debug or boundary scan. There is an internal pull-down on JTG_TRST to ensure internal emulation logic will
always be properly initialized during power-up reset.
Table 30 and Figure 9 show the relationship between power supply startup and processor reset timing, related to the clock generation unit
(CGU) and reset control unit (RCU). In Figure 9, VDD_SUPPLIES are VDD_INT, VDD_EXT, VDD_DMC, VDD_USB, VDD_RTC, VDD_OTP, and VDD_HADC
.
There is no power supply sequencing requirement for the ADSP-BF70x processor. However, if saving power during power-on is import-
ant, bringing up VDD_INT last is recommended. This avoids a small current drain in the VDD_INT domain during the transition period of I/O
voltages from 0 V to within the voltage specification.

SMC Read Cycle Timing With Reference to SYS_CLKOUT
The following SMC specifications with respect to SYS_CLKOUT are given to accommodate the connection of the SMC to
programmable logic devices. These specifications assume that SYS_CLKOUT is outputting a buffered version of SCLK0 by
setting CGU_CLKOUTSEL.CLKOUTSEL = 0x3. However, SCLK0 must not run faster than the maximum fOCLK specification.
For this example, RST = 0x2, RAT = 0x4, and RHT = 0x1.

Serial Ports
To determine whether serial port (SPORT) communication is possible between two devices at clock speed n, the following specifications
must be confirmed: 1) frame sync delay and frame sync setup and hold, 2) data delay and data setup and hold, and 3) serial clock
(SPT_CLK) width. In Figure 27 either the rising edge or the falling edge of SPT_CLK (external or internal) can be used as the active
sampling edge.
When externally generated the SPORT clock is called fSPTCLKEXT
:

t
= ------------------------------
SPTCLKEXT

When internally generated, the programmed SPORT clock (fSPTCLKPROG) frequency in MHz is set by the following equation where CLKDIV
is a field in the SPORT_DIV register that can be set from 0 to 65,535:

Serial Peripheral Interface (SPI) Port—Master Timing
Table 54 and Figure 31 describe serial peripheral interface (SPI) port master operations.
When internally generated, the programmed SPI clock (fSPICLKPROG) frequency in MHz is set by the following equation where BAUD is a
field in the SPI_CLK register that can be set from 0 to 65,535:
f
SCLK0
f
= -------------------------------
SPICLKPROG

Note that:
• In dual mode data transmit, the SPI_MISO signal is also an output.
• In quad mode data transmit, the SPI_MISO, SPI_D2, and SPI_D3 signals are also outputs.
• In dual mode data receive, the SPI_MOSI signal is also an input.
• In quad mode data receive, the SPI_MOSI, SPI_D2, and SPI_D3 signals are also inputs.
• To add additional frame delays, see the documentation for the SPI_DLY register in the hardware reference manual.

Serial Peripheral Interface (SPI) Port—Slave Timing
Table 55 and Figure 32 describe serial peripheral interface (SPI) port slave operations. Note that:
• In dual mode data transmit, the SPI_MOSI signal is also an output.
• In quad mode data transmit, the SPI_MOSI, SPI_D2, and SPI_D3 signals are also outputs.
• In dual mode data receive, the SPI_MISO signal is also an input.
• In quad mode data receive, the SPI_MISO, SPI_D2, and SPI_D3 signals are also inputs.
• In SPI slave mode, the SPI clock is supplied externally and is called fSPICLKEXT

Enhanced Parallel Peripheral Interface Timing
The following tables and figures describe enhanced parallel peripheral interface timing operations. The POLC bits in the EPPI_CTL
register may be used to set the sampling/driving edges of the EPPI clock.
When internally generated, the programmed PPI clock (fPCLKPROG) frequency in MHz is set by the following equation where VALUE is a
field in the EPPI_CLKDIV register that can be set from 0 to 65,535:
fSCLK0
fPCLKPROG = --------------------------------
VALUE + 1
1
tPCLKPROG = ------------------------

When externally generated the EPPI_CLK is called fPCLKEXT

Mobile Storage Interface (MSI) Controller Timing
Table 64 and Figure 49 show I/O timing, related to the mobile storage interface (MSI).
The MSI timing depends on the period of the input clock that has been routed to the MSI peripheral (tMSICLKIN) by setting the
MSI0_UHS_EXT register. See Table 63 for this information.

(fMSICLKPROG) frequency in MHz is set by the following equation where DIV0 is a field in the MSI_CLKDIV register that can be set from 0 to

:

signal switches to when the output voltage reaches VTRIP (high)
or VTRIP (low). For VDD_EXT (nominal) = 1.8 V, VTRIP (high) is
1.05 V, and VTRIP (low) is 0.75 V. For VDD_EXT (nominal) = 3.3 V,
VTRIP (high) is 1.9 V, and VTRIP (low) is 1.4 V. Time tTRIP is the
interval from when the output starts driving to when the output
reaches the VTRIP (high) or VTRIP (low) trip voltage.

Time tENA is calculated as shown in the equation:

tENA = tENA_MEASURED – tTRIP

Output balls are considered to be disabled when they stop driv-
ing, go into a high impedance state, and start to decay from their
output high or low voltage. The output disable time tDIS is the
difference between tDIS_MEASURED and tDECAY as shown on the left
side of Figure 63.

Figure 61. Driver Type B and Device Driver C (DDR Drive Strength 60 Ω)
TEST CONDITIONS
All timing requirements appearing in this data sheet were mea-
sured under the conditions described in this section. Figure 62
shows the measurement point for ac measurements (except out-
put enable/disable). The measurement point VMEAS is VDD_EXT/2
for VDD_EXT (nominal) = 1.8 V/3.3 V.
tDIS = tDIS_MEASURED – tDECAY
The time for the voltage on the bus to decay by ΔV is dependent
on the capacitive load, CL and the load current, IL. This decay
time can be approximated by the equation:
tDECAY = CLV IL
INPUT
OR
OUTPUT
V
V
MEAS
MEAS
The time tDECAY is calculated with test loads CL and IL, and with
V equal to 0.25 V for VDD_EXT (nominal) = 3.3 V and 0.15 V for
VDD_EXT (nominal) = 1.8V.
Figure 62. Voltage Reference Levels for AC Measurements
(Except Output Enable/Disable)
The time tDIS_MEASURED is the interval from when the reference
signal switches, to when the output voltage decays ΔV from the
measured output high or output low voltage.
Output Enable Time Measurement
Example System Hold Time Calculation
Output balls are considered to be enabled when they have made
a transition from a high impedance state to the point when they
start driving.
The output enable time tENA is the interval from the point when
a reference signal reaches a high or low voltage level to the point
when the output starts driving as shown on the right side of
Figure 63.
To determine the data output hold time in a particular system,
first calculate tDECAY using the previous equation. Choose ΔV to
be the difference between the processor’s output voltage and the
input threshold for the device requiring the hold time. CL is the
total bus capacitance (per data line), and IL is the total leakage or
three-state current (per data line). The hold time will be tDECAY
plus the various output disable times as specified in the Timing
Specifications on Page 60.

Capacitive Loading
35
Output delays and holds are based on standard capacitive loads
of an average of 6 pF on all balls (see Figure 64). VLOAD is equal
to VDD_EXT/2. The graphs of Figure 65 through Figure 68 show
how output rise time varies with capacitance. The delay and
hold specifications given should be derated by a factor derived
from these figures. The graphs in these figures may not be linear
outside the ranges shown.

ENVIRONMENTAL CONDITIONS
To determine the junction temperature on the application
printed circuit board, use the following equation:
TJ = TCASE + JT PD
where:
TJ = Junction temperature (°C).
T
CASE = Case temperature (°C) measured by customer at top
center of package.
JT = From Table 65 and Table 66.
PD = Power dissipation (see Total Internal Power Dissipation
on Page 56 for the method to calculate PD).
Values of JA are provided for package comparison and printed
circuit board design considerations. JA can be used for a first
order approximation of TJ by the equation:
TJ = TA + JA PD
where:
TA = Ambient temperature (°C).
Values of JC are provided for package comparison and printed
circuit board design considerations when an external heat sink
is required.
In Table 65 and Table 66, airflow measurements comply with
JEDEC standards JESD51-2 and JESD51-6. The junction-to-
case measurement complies with MIL-STD-883 (Method
1012.1). All measurements use a 2S2P JEDEC test board.
