ADSP-21364  
GENERAL DESCRIPTION  
The ADSP-21364 SHARC processor is a member of the SIMD  
SHARC family of DSPs that feature Analog Devices’ Super Har-  
vard Architecture. The ADSP-21364 is source code compatible  
with the ADSP-2126x, and ADSP-2116x DSPs as well as with  
first generation ADSP-2106x SHARC processors in SISD (sin-  
gle-instruction, single-data) mode. The ADSP-21364 is a 32-  
bit/40-bit floating-point processor optimized for professional  
audio applications with a large on-chip SRAM, multiple internal  
buses to eliminate I/O bottlenecks, and an innovative digital  
audio interface (DAI).  
• On-chip mask-programmable ROM (4M bit)  
• 8-bit or 16-bit parallel port that supports interfaces to off-  
chip memory peripherals  
• JTAG test access port  
The block diagram of the ADSP-21364 on Page 7, illustrates the  
following architectural features:  
• DMA controller  
• Six full duplex serial ports  
• Two SPI-compatible interface ports—primary on dedi-  
cated pins secondary on DAI pins  
As shown in the functional block diagram on Page 1, the  
ADSP-21364 uses two computational units to deliver a signifi-  
cant performance increase over previous SHARC processors on  
a range of signal processing algorithms. Fabricated in a state-of-  
the-art, high speed, CMOS process, the ADSP-21364 processor  
achieves an instruction cycle time of 3.0 ns at 333 MHz. With its  
SIMD computational hardware, the ADSP-21364 can perform 2  
GFLOPS running at 333 MHz.  
• Digital audio interface that includes two precision clock  
generators (PCG), an input data port (IDP), an S/PDIF  
receiver/transmitter, eight channels asynchronous sample  
rate converters, six serial ports, eight serial interfaces, a 20-  
bit parallel input port, 10 interrupts, six flag outputs, six  
flag inputs, three timers, and a flexible signal routing unit  
(SRU)  
Table 1 shows performance benchmarks for the ADSP-21364  
running at 333 MHz.  
Figure 2 on Page 5 shows one sample configuration of a SPORT  
using the precision clock generators to interface with an I2S  
ADC and an I2S DAC with a much lower jitter clock than the  
serial port would generate itself. Many other SRU configura-  
tions are possible.

The ADSP-21364 is code compatible at the assembly level with  
the ADSP-2126x, ADSP-21160 and ADSP-21161, and with the  
first generation ADSP-2106x SHARC DSPs. The ADSP-21364  
shares architectural features with the ADSP-2126x and  
ADSP-2116x SIMD SHARC processors, as detailed in the fol-  
lowing sections.

SIMD Computational Engine

The ADSP-21364 contains two computational processing ele-  
ments that operate as a single-instruction multiple-data (SIMD)  
engine. The processing elements are referred to as PEX and PEY  
and each contains an ALU, multiplier, shifter, and register file.  
PEX is always active, and PEY may be enabled by setting the  
PEYEN mode bit in the MODE1 register. When this mode is  
enabled, the same instruction is executed in both processing ele-  
ments, but each processing element operates on different data.  
This architecture is efficient at executing math intensive signal  
processing algorithms.  
The ADSP-21364 continues SHARC’s industry-leading stan-  
dards of integration for DSPs, combining a high performance  
32-bit DSP core with integrated, on-chip system features.  
The block diagram of the ADSP-21364 on Page 1, illustrates the  
following architectural features:  
• Two processing elements, each of which comprises an  
ALU, multiplier, shifter and data register file  
• Data address generators (DAG1, DAG2)  
• Program sequencer with instruction cache  
Entering SIMD mode also has an effect on the way data is trans-  
ferred between memory and the processing elements. When in  
SIMD mode, twice the data bandwidth is required to sustain  
computational operation in the processing elements. Because of  
this requirement, entering SIMD mode also doubles the band-  
width between memory and the processing elements. When  
using the DAGs to transfer data in SIMD mode, two data values  
are transferred with each access of memory or the register file.  
• PM and DM buses capable of supporting four 32-bit data  
transfers between memory and the core at every core pro-  
cessor cycle  
• Three programmable interval timers with PWM genera-  
tion, PWM capture/pulse width measurement, and  
external event counter capabilities  
• On-chip SRAM (3M bit)

Figure 2. ADSP-21364 System Sample Configuration  
Independent, Parallel Computation Units  
Single-Cycle Fetch of Instruction and Four Operands  
Within each processing element is a set of computational units.  
The computational units consist of an arithmetic/logic unit  
(ALU), multiplier, and shifter. These units perform all opera-  
tions in a single cycle. The three units within each processing  
element are arranged in parallel, maximizing computational  
throughput. Single multifunction instructions execute parallel  
ALU and multiplier operations. In SIMD mode, the parallel  
ALU and multiplier operations occur in both processing ele-  
ments. These computation units support IEEE 32-bit, single-  
precision floating-point, 40-bit, extended-precision floating-  
point, and 32-bit, fixed-point data formats.  
The ADSP-21364 features an enhanced Harvard architecture in  
which the data memory (DM) bus transfers data and the pro-  
gram memory (PM) bus transfers both instructions and data  
(see Figure 1 on Page 1). With the ADSP-21364’s separate pro-  
gram and data memory buses and on-chip instruction cache,  
the processor can simultaneously fetch four operands (two over  
each data bus) and one instruction (from the cache), all in a sin-  
gle cycle.  
Instruction Cache  
The ADSP-21364 includes an on-chip instruction cache that  
enables three-bus operation for fetching an instruction and four  
data values. The cache is selective—only the instructions whose  
fetches conflict with PM bus data accesses are cached. This  
cache allows full-speed execution of core, looped operations  
such as digital filter multiply-accumulates, and FFT butterfly  
processing.  
Data Register File  
A general-purpose data register file is contained in each  
processing element. The register files transfer data between the  
computation units and the data buses, and store intermediate  
results. These 10-port, 32-register (16 primary, 16 secondary)  
register files, combined with the ADSP-2136x enhanced Har-  
vard architecture, allow unconstrained data flow between  
computation units and internal memory. The registers in PEX  
are referred to as R0–R15 and in PEY as S0–S15.  
Data Address Generators with Zero-Overhead Hardware  
Circular Buffer Support  
The ADSP-21364’s two data address generators (DAGs) are  
used for indirect addressing and implementing circular data  
buffers in hardware. Circular buffers allow efficient program-  
ming of delay lines and other data structures required in digital

ADSP-21364  
signal processing, and are commonly used in digital filters and  
Fourier transforms. The two DAGs of the ADSP-21364 contain  
sufficient registers to allow the creation of up to 32 circular buff-  
ers (16 primary register sets, 16 secondary). The DAGs  
automatically handle address pointer wraparound, reduce over-  
head, increase performance, and simplify implementation.  
Circular buffers can start and end at any memory location.  
On-Chip Memory  
The ADSP-21364 contains three megabits of internal SRAM.  
Each block can be configured for different combinations of code  
and data storage (see Table 2 on Page 6). Each memory block  
supports single-cycle, independent accesses by the core proces-  
sor and I/O processor. The ADSP-21364 memory architecture,  
in combination with its separate on-chip buses, allow two data  
transfers from the core and one from the I/O processor, in a sin-  
gle cycle.  
Flexible Instruction Set  
The 48-bit instruction word accommodates a variety of parallel  
operations, for concise programming. For example, the  
ADSP-21364 can conditionally execute a multiply, an add, and a  
subtract in both processing elements while branching and fetch-  
ing up to four 32-bit values from memory—all in a single  
instruction.  
The ADSP-21364’s SRAM can be configured as a maximum of  
96K words of 32-bit data, 192K words of 16-bit data, 64K words  
of 48-bit instructions (or 40-bit data), or combinations of differ-  
ent word sizes up to three megabits. All of the memory can be  
accessed as 16-bit, 32-bit, 48-bit, or 64-bit words. A 16-bit float-  
ing-point storage format is supported that effectively doubles  
the amount of data that may be stored on-chip. Conversion  
between the 32-bit floating-point and 16-bit floating-point for-  
mats is performed in a single instruction. While each memory  
block can store combinations of code and data, accesses are  
most efficient when one block stores data using the DM bus for  
transfers, and the other block stores instructions and data using  
the PM bus for transfers.

ADSP-21364  
Using the DM bus and PM buses, with one dedicated to each  
memory block assures single-cycle execution with two data  
transfers. In this case, the instruction must be available in the  
cache.  
Digital Audio Interface (DAI)  
The digital audio interface (DAI) provides the ability to connect  
various peripherals to any of the SHARC’s DAI pins  
(DAI_P20–1).  
DMA Controller  
Programs make these connections using the signal routing unit  
(SRU, shown in Figure 3).  
The ADSP-21364’s on-chip DMA controller allows data trans-  
fers without processor intervention. The DMA controller  
operates independently and invisibly to the processor core,  
allowing DMA operations to occur while the core is simulta-  
neously executing its program instructions. DMA transfers can  
occur between the ADSP-21364’s internal memory and its serial  
ports, the SPI-compatible (serial peripheral interface) ports, the  
IDP (input data port), the parallel data acquisition port (PDAP),  
or the parallel port. Twenty-five channels of DMA are available  
on the ADSP-21364—two for the SPI interface, two for mem-  
ory-to-memory transfers, 12 via the serial ports, eight via the  
input data port, and one via the processor’s parallel port. Pro-  
grams can be downloaded to the ADSP-21364 using DMA  
transfers. Other DMA features include interrupt generation  
upon completion of DMA transfers, and DMA chaining for  
automatic linked DMA transfers.  
The SRU is a matrix routing unit (or group of multiplexers) that  
enables the peripherals provided by the DAI to be intercon-  
nected under software control. This allows easy use of the DAI-  
associated peripherals for a much wider variety of applications  
by using a larger set of algorithms than is possible with noncon-  
figurable signal paths.  
The DAI also includes six serial ports, two precision clock gen-  
erators (PCGs), eight channels of asynchronous sample rate  
converters, an input data port (IDP), an SPI port, six flag out-  
puts and six flag inputs, and three timers. The IDP provides an  
additional input path to the ADSP-21364 core, configurable as  
either eight channels of I2S serial data or as seven channels plus  
a single 20-bit wide synchronous parallel data acquisition port.  
Each data channel has its own DMA channel that is indepen-  
dent from the ADSP-21364’s serial ports.

The ADSP-21364 features six synchronous serial ports that pro-  
vide an inexpensive interface to a wide variety of digital and  
mixed-signal peripheral devices such as Analog Devices’  
AD183x family of audio codecs, ADCs, and DACs. The serial  
ports are made up of two data lines, a clock, and frame sync. The  
data lines can be programmed to either transmit or receive and  
each data line has a dedicated DMA channel.

The serial ports operate at a maximum data rate of 50M bits/s.  
Serial port data can be automatically transferred to and from  
on-chip memory via dedicated DMA channels. Each of the  
serial ports can work in conjunction with another serial port to  
provide TDM support. One SPORT provides two transmit sig-  
nals while the other SPORT provides the two receive signals.  
The frame sync and clock are shared.

sample on the high segment of the frame sync, the other on the  
low segment of the frame sync. Programs have control over var-  
ious attributes of this mode.

ADSP-21364  
Each of the serial ports supports the left-justified sample pair  
and I2S protocols (I2S is an industry standard interface com-  
monly used by audio codecs, ADCs and DACs such as the  
Analog Devices AD183x family), with two data pins, allowing  
four left-justified sample pair or I2S channels (using two stereo  
devices) per serial port, with a maximum of up to 24 I2S chan-  
nels. The serial ports permit little-endian or big-endian  
transmission formats and word lengths selectable from 3 bits to  
32 bits. For the left-justified sample pair and I2S modes, data-  
word lengths are selectable between 8 bits and 32 bits. Serial  
ports offer selectable synchronization and transmit modes as  
well as optional μ-law or A-law companding selection on a per  
channel basis. Serial port clocks and frame syncs can be inter-  
nally or externally generated.  
The sample rate converter (SRC) contains four SRC blocks and  
is the same core as that used in the AD1896 192 kHz stereo  
asynchronous sample rate converter providing up to 140 dB  
SNR. The SRC block is used to perform synchronous or asyn-  
chronous sample rate conversion across independent stereo  
channels, without using internal processor resources. The four  
SRC blocks can also be configured to operate together to con-  
vert multichannel audio data without phase mismatches.  
Finally, the SRC is used to clean up audio data from jittery clock  
sources such as the S/PDIF receiver.  
Pulse-Width Modulation  
The PWM module is a flexible, programmable, PWM waveform  
generator that can be programmed to generate the required  
switching patterns for various applications related to motor and  
engine control or audio power control. The PWM generator can  
generate either center-aligned or edge-aligned PWM wave-  
forms. In addition, it can generate complementary signals on  
two outputs in paired mode or independent signals in non-  
paired mode (applicable to a single group of four PWM  
waveforms).  
Parallel Port  
The parallel port provides interfaces to SRAM and peripheral  
devices. The multiplexed address and data pins (AD15–0) can  
access 8-bit devices with up to 24 bits of address, or 16-bit  
devices with up to 16 bits of address. In either mode, 8- or 16-  
bit, the maximum data transfer rate is 55M bytes/sec.  
DMA transfers are used to move data to and from internal  
memory. Access to the core is also facilitated through the paral-  
lel port register read/write functions. The RD, WR, and ALE  
(address latch enable) pins are the control pins for the parallel  
port.  
The entire PWM module has four groups of four PWM outputs  
each. Therefore this module generates 16 PWM outputs in total.  
Each PWM group produces two pairs of PWM signals on the  
four PWM outputs.  
The PWM generator is capable of operating in two distinct  
modes while generating center-aligned PWM waveforms: single  
update mode, or double update mode. In single update mode  
the duty cycle values are programmable only once per PWM  
period. This results in PWM patterns that are symmetrical  
around the midpoint of the PWM period. In double update  
mode, a second updating of the PWM registers is implemented  
at the mid-point of the PWM period. In this mode, it is possible  
to produce asymmetrical PWM patterns that produce lower  
harmonic distortion in three-phase PWM inverters.  
Serial Peripheral (Compatible) Interface  
The ADSP-21364 SHARC processor contains two serial periph-  
eral interface ports (SPIs). The SPI is an industry standard  
synchronous serial link, enabling the ADSP-21364 SPI-compat-  
ible port to communicate with other SPI-compatible devices.  
The SPI consists of two data pins, one device select pin, and one  
clock pin. It is a full-duplex synchronous serial interface, sup-  
porting both master and slave modes. The SPI port can operate  
in a multimaster environment by interfacing with up to four  
other SPI-compatible devices, either acting as a master or slave  
device. The ADSP-21364 SPI-compatible peripheral implemen-  
tation also features programmable baud rate and clock phase  
and polarities. The ADSP-21364 SPI-compatible port uses open  
drain drivers to support a multimaster configuration and to  
avoid data contention.  
Timers  
The ADSP-21364 has a total of four timers: a core timer able to  
generate periodic software interrupts and three general-purpose  
timers that can generate periodic interrupts and be indepen-  
dently set to operate in one of three modes:  
• Pulse waveform generation mode  
• Pulse width count/capture mode  
• External event watchdog mode  
S/PDIF-Compatible Digital Audio Receiver/Transmitter  
and Synchronous/Asynchronous Sample Rate Converter  
The S/PDIF transmitter has no separate DMA channels. It  
receives audio data in serial format and converts it into a  
biphase encoded signal. The serial data input to the transmitter  
can be formatted as left-justified, I2S, or right-justified with  
word widths of 16, 18, 20, or 24 bits.  
The core timer can be configured to use FLAG3 as a timer  
expired signal, and each general-purpose timer has one bidirec-  
tional pin and four registers that implement its mode of  
operation: a 6-bit configuration register, a 32-bit count register,  
a 32-bit period register, and a 32-bit pulse width register. A sin-  
gle control and status register enables or disables all three  
general-purpose timers independently.  
The serial data, clock, and frame sync inputs to the S/PDIF  
transmitter are routed through the signal routing unit (SRU).  
They can come from a variety of sources such as the SPORTs,  
external pins, the precision clock generators (PCGs), or the  
sample rate converters (SRC) and are controlled by the SRU  
control registers.  
Program Booting  
The internal memory of the ADSP-21364 boots at system  
power-up from an 8-bit EPROM via the parallel port, an SPI  
master, an SPI slave or an internal boot. Booting is determined

by the boot configuration (BOOTCFG1–0) pins (see Table 6 on  
Page 14). Selection of the boot source is controlled via the SPI as  
either a master or slave device.  
For complete information on Analog Devices’ SHARC DSP  
Tools product line of JTAG emulator operation, see the appro-  
priate “Emulator Hardware User's Guide”.  
Phase-Locked Loop  
DEVELOPMENT TOOLS  
The ADSP-21364 uses an on-chip phase-locked loop (PLL) to  
generate the internal clock for the core. On power up, the  
CLKCFG1–0 pins are used to select ratios of 32:1, 16:1, and 6:1  
(see Table 7 on Page 14). After booting, numerous other ratios  
can be selected via software control. The ratios are made up of  
software configurable numerator values from 1 to 64 and soft-  
ware configurable divisor values of 1, 2, 4, and 8.  
The ADSP-21364 is supported with a complete set of  
CROSSCORE® software and hardware development tools,  
including Analog Devices emulators and VisualDSP++® devel-  
opment environment. The same emulator hardware that  
supports other SHARC processors also fully emulates the  
ADSP-21364.  
The VisualDSP++ project management environment lets pro-  
grammers develop and debug an application. This environment  
includes an easy to use assembler (which is based on an alge-  
braic syntax), an archiver (librarian/library builder), a linker, a  
loader, a cycle-accurate instruction-level simulator, a C/C++  
compiler, and a C/C++ run-time library that includes DSP and  
mathematical functions. A key point for these tools is C/C++  
code efficiency. The compiler has been developed for efficient  
translation of C/C++ code to DSP assembly. The SHARC has  
architectural features that improve the efficiency of compiled  
C/C++ code.  
Power Supplies  
The ADSP-21364 has separate power supply connections for the  
internal (VDDINT), external (VDDEXT), and analog (AVDD/AVSS  
)
power supplies. The internal and analog supplies must meet the  
1.2 V requirement for K and B grade models, and the 1.0 V  
requirement for W grade models. The external supply must  
meet the 3.3 V requirement. All external supply pins must be  
connected to the same power supply.  
Note that the analog supply pin (AVDD) powers the ADSP-  
21364’s internal clock generator PLL. To produce a stable clock,  
it is recommended that PCB designs use an external filter circuit  
for the AVDD pin. Place the filter components as close as possi-  
ble to the AVDD/AVSS pins. For an example circuit, see Figure 4.  
(A recommended ferrite chip is the muRata  
The VisualDSP++ debugger has a number of important fea-  
tures. Data visualization is enhanced by a plotting package that  
offers a significant level of flexibility. This graphical representa-  
tion of user data enables the programmer to quickly determine  
the performance of an algorithm. As algorithms grow in com-  
plexity, this capability can have increasing significance on the  
designer’s development schedule, increasing productivity. Sta-  
tistical profiling enables the programmer to nonintrusively poll  
the processor as it is running the program. This feature, unique  
to VisualDSP++, enables the software developer to passively  
gather important code execution metrics without interrupting  
the real-time characteristics of the program. Essentially, the  
developer can identify bottlenecks in software quickly and effi-  
ciently. By using the profiler, the programmer can focus on  
those areas in the program that impact performance and take  
corrective action.  
BLM18AG102SN1D). To reduce noise coupling, the PCB  
should use a parallel pair of power and ground planes for  
VDDINT and GND. Use wide traces to connect the bypass capac-  
itors to the analog power (AVDD) and ground (AVSS) pins. Note  
that the AVDD and AVSS pins specified in Figure 4 are inputs to  
the processor and not the analog ground plane on the board—  
the AVSS pin should connect directly to digital ground (GND) at  
the chip.

Target Board JTAG Emulator Connector  
Analog Devices DSP Tools product line of JTAG emulators uses  
the IEEE 1149.1 JTAG test access port of the ADSP-21364 pro-  
cessor to monitor and control the target board processor during  
emulation. Analog Devices DSP Tools product line of JTAG  
emulators provides emulation at full processor speed, allowing  
inspection and modification of memory, registers, and proces-  
sor stacks. The processor's JTAG interface ensures that the  
emulator will not affect target system loading or timing.

ADSP-21364  
The VisualDSP++ IDDE lets programmers define and manage  
DSP software development. Its dialog boxes and property pages  
let programmers configure and manage all of the SHARC devel-  
opment tools, including the color syntax highlighting in the  
VisualDSP++ editor. This capability permits programmers to:  
access port (TAP) on each JTAG DSP. Nonintrusive in-circuit  
emulation is assured by the use of the processor’s JTAG inter-  
face—the emulator does not affect target system loading or  
timing. The emulator uses the TAP to access the internal fea-  
tures of the processor, allowing the developer to load code, set  
breakpoints, observe variables, observe memory, and examine  
registers. The processor must be halted to send data and com-  
mands, but once an operation has been completed by the  
emulator, the processor system is set running at full speed with  
no impact on system timing.  
• Control how the development tools process inputs and  
generate outputs  
• Maintain a one-to-one correspondence with the tool’s

The VisualDSP++ Kernel (VDK) incorporates scheduling and  
resource management tailored specifically to address the mem-  
ory and timing constraints of DSP programming. These  
capabilities enable engineers to develop code more effectively,  
eliminating the need to start from the very beginning, when  
developing new application code. The VDK features include  
threads, critical and unscheduled regions, semaphores, events,  
and device flags. The VDK also supports priority-based, pre-  
emptive, cooperative, and time-sliced scheduling approaches. In  
addition, the VDK was designed to be scalable. If the application  
does not use a specific feature, the support code for that feature  
is excluded from the target system.  
To use these emulators, the target board must include a header  
that connects the processor’s JTAG port to the emulator.  
For details on target board design issues including mechanical  
layout, single processor connections, multiprocessor scan  
chains, signal buffering, signal termination, and emulator pod  
logic, see the EE-68: Analog Devices JTAG Emulation Technical  
Reference on the Analog Devices website (www.analog.com)—  
use site search on “EE-68.” This document is updated regularly  
to keep pace with improvements to emulator support.  
Evaluation Kit  
Analog Devices offers a range of EZ-KIT Lite evaluation plat-  
forms to use as a cost-effective method to learn more about  
developing or prototyping applications with Analog Devices  
processors, platforms, and software tools. Each EZ-KIT Lite  
includes an evaluation board along with an evaluation suite of  
the VisualDSP++ development and debugging environment  
with the C/C++ compiler, assembler, and linker. Also included  
are sample application programs, power supply, and a USB  
cable. All evaluation versions of the software tools are limited  
for use only with the EZ-KIT Lite product.  
Because the VDK is a library, a developer can decide whether to  
use it or not. The VDK is integrated into the VisualDSP++  
development environment, but can also be used via standard  
command line tools. When the VDK is used, the development  
environment assists the developer with many error-prone tasks  
and assists in managing system resources, automating the gen-  
eration of various VDK-based objects, and visualizing the  
system state, when debugging an application that uses the VDK.  
VisualDSP++ Component Software Engineering (VCSE) is  
Analog Devices’ technology for creating, using, and reusing  
software components (independent modules of substantial  
functionality) to quickly and reliably assemble software applica-  
tions. It also can be used for downloading components from the  
Web, dropping them into the application, and publishing com-  
ponent archives from within VisualDSP++. VCSE supports  
component implementation in C/C++ or assembly language.  
The USB controller on the EZ-KIT Lite board connects the  
board to the USB port of the user’s PC, enabling the Visu-  
alDSP++ 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 allows in-  
circuit programming of the on-board Flash device to store user-  
specific boot code, enabling the board to run as a standalone  
unit without being connected to the PC.  
Use the expert linker to visually manipulate the placement of  
code and data on the embedded system. View memory utiliza-  
tion in a color-coded graphical form, easily move code and data  
to different areas of the processor or external memory with a  
drag of the mouse, and examine run-time stack and heap usage.  
The expert linker is fully compatible with the existing linker def-  
inition file (LDF), allowing the developer to move between the  
graphical and textual environments.  
With a full version of VisualDSP++ installed (sold separately),  
engineers can develop software for the EZ-KIT Lite or any cus-  
tom defined system. Connecting one of Analog Devices JTAG  
emulators to the EZ-KIT Lite board enables high speed, non-  
intrusive emulation.

PIN FUNCTION DESCRIPTIONS  
ADSP-21364 pin definitions are listed below. Inputs identified  
as synchronous (S) must meet timing requirements with respect  
to CLKIN (or with respect to TCK for TMS and TDI). Inputs

to CLKIN (or to TCK for TRST). Tie or pull unused inputs to  
• DAI_Px, SPICLK, MISO, MOSI, EMU, TMS, TRST, TDI,  
and AD15–0 (Note: These pins have pull-up resistors.)  
The following symbols appear in the Type column of Table 3:  
A = asynchronous, G = ground, I = input, O = output,  
P = power supply, S = synchronous, (A/D) = active drive, (O/D)  
= open drain, and T = three-state, (pd) = pull-down resistor,

Parallel Port Address/Data. The ADSP-21364 parallel port and its corresponding  
DMA unit output addresses and data for peripherals on these multiplexed pins. The  
multiplex state is determined by the ALE pin. The parallel port can operate in either  
8-bit or 16-bit mode. Each AD pin has a 22.5 kΩ internal pull-up resistor. See Address  
Data Modes on Page 14 for details of the AD pin operation.  
For 8-bit mode: ALE is automatically asserted whenever a change occurs in the upper  
16 external address bits, A23–8; ALE is used in conjunction with an external latch to  
retain the values of the A23–8.

registers of these peripherals then determines the exact behavior of the pin. Any input  
or output signal present in the SRU may be routed to any of these pins. The SRU  
provides the connection from the serial ports, input data port, precision clock gener-  
ators and timers, sample rate converters and SPI to the DAI_P20–1 pins These pins  
have internal 22.5 kΩ pull-up resistors which are enabled on reset. These pull-ups can  
be disabled in the DAI_PIN_PULLUP register.

SPICLK  
I/O  
(pu)  
Three-state with

Serial Peripheral Interface Clock Signal. Driven by the master, this signal controls  
the rate at which data is transferred. The master may transmit data at a variety of baud  
rates. SPICLK cycles once for each bit transmitted. SPICLK is a gated clock that is active  
during data transfers, only for the length of the transferred word. Slave devices ignore  
the serial clock if the slave select input is driven inactive (HIGH). SPICLK is used to shift  
out and shift in the data driven on the MISO and MOSI lines. The data is always shifted  
out on one clock edge and sampled on the opposite edge of the clock. Clock polarity  
and clock phase relative to data are programmable into the SPICTL control register  
and define the transfer format. SPICLK has a 22.5 kΩ internal pull-up resistor.  
SPIDS  
I
Input only  
Serial Peripheral Interface Slave Device Select. An active low signal used to select  
the processor as an SPI slave device. This input signal behaves like a chip select, and  
is provided by the master device for the slave devices. In multimaster mode the  
processor’s SPIDS signal can be driven by a slave device to signal to the processor (as  
SPI master) that an error has occurred, as some other device is also trying to be the  
master device. If asserted low when the device is in master mode, it is considered a  
multimaster error. For a single-master, multiple-slave configuration where flag pins  
are used, this pin must be tied or pulled high to VDDEXT on the master device. For  
processor to processor SPI interaction, any of the master processor’s flag pins can be  
used to drive the SPIDS signal on the SPI slave device.

SPI Master Out Slave In. If the ADSP-21364 is configured as a master, the MOSI pin  
becomes a data transmit (output) pin, transmitting output data. If the processor is  
configured as a slave, the MOSI pin becomes a data receive (input) pin, receiving input  
data. In an SPI interconnection, the data is shifted out from the MOSI output pin of the  
master and shifted into the MOSI input(s) of the slave(s). MOSI has a 22.5 kΩ internal  
pull-up resistor.  
I/O (O/D)  
(pu)  
Three-state with

SPI Master In Slave Out. If the ADSP-21364 is configured as a master, the MISO pin  
becomes a data receive (input) pin, receiving input data. If the processor is configured  
as a slave, the MISO pin becomes a data transmit (output) pin, transmitting output  
data. In a SPI interconnection, the data is shifted out from the MISO output pin of the  
slave and shifted into the MISO input pin of the master. MISO has a 22.5 kΩ internal  
pull-up resistor. MISO can be configured as O/D by setting the OPD bit in the SPICTL  
register.  
Note: Only one slave is allowed to transmit data at any given time. To enable broadcast  
transmission to multiple SPI-slaves, the processor’s MISO pin may be disabled by

greater than those indicated in the operational sections of this specification is not implied.  
Exposure to absolute maximum rating conditions for extended periods may affect device  
reliability.  
ESD SENSITIVITY  
CAUTION  
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily  
accumulate on the human body and test equipment and can discharge without detection.  
Although the ADSP-21364 features proprietary ESDprotectioncircuitry, permanent damage may  
occur on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD  
precautions are recommended to avoid performance degradation or loss of functionality.

ADSP-21364  
Table 9. Clock Periods  
TIMING SPECIFICATIONS  
The ADSP-21364’s internal clock (a multiple of CLKIN) pro-  
vides the clock signal for timing internal memory, processor  
core, serial ports, and parallel port (as required for read/write  
strobes in asynchronous access mode). During reset, program  
the ratio between the processor’s internal clock frequency and  
external (CLKIN) clock frequency with the CLKCFG1–0 pins.  
To determine switching frequencies for the serial ports, divide  
down the internal clock, using the programmable divider con-  
trol of each port (DIVx for the serial ports).

The ADSP-21364’s internal clock switches at higher frequencies  
than the system input clock (CLKIN). To generate the internal  
clock, the processor uses an internal phase-locked loop (PLL).  
This PLL-based clocking minimizes the skew between the sys-  
tem clock (CLKIN) signal and the processor’s internal clock (the  
clock source for the parallel port logic and I/O pads).  
SR = serial port-to-peripheral clock ratio (wide range, determined by  
SPORT CLKDIV)  
SPIR = SPI-to-peripheral clock ratio (wide range, determined by  
SPIBAUD register)  
DAI_Px = serial port clock  
SPICLK = SPI clock  
Switching Characteristics specify how the processor changes its  
signals. Circuitry external to the processor must be designed for  
compatibility with these signal characteristics. Switching char-  
acteristics describe what the processor will do in a given  
circumstance. Use switching characteristics to ensure that any  
timing requirement of a device connected to the processor (such  
as memory) is satisfied.  
Note the definitions of various clock periods that are a function  
of CLKIN and the appropriate ratio control shown inTable 8.

Use the exact timing information given. Do not attempt to  
derive parameters from the addition or subtraction of others.  
While addition or subtraction would yield meaningful results  
for an individual device, the values given in this data sheet  
reflect statistical variations and worst cases. Consequently, it is  
not meaningful to add parameters to derive longer times. See

1 Valid VDDINT/VDDEXT assumes that the supplies are fully ramped to their 1.2 and 3.3 volt rails. Voltage ramp rates can vary from microseconds to hundreds of milliseconds  
depending on the design of the power supply subsystem.  
2 Assumes a stable CLKIN signal, after meeting worst-case startup timing of crystal oscillators. Refer to your crystal oscillator manufacturer’s data sheet for startup time.  
Assume a 25 ms maximum oscillator startup time if using the XTAL pin and internal oscillator circuit in conjunction with an external crystal.  
3 Applies after the power-up sequence is complete. Subsequent resets require a minimum of 4 CLKIN cycles for RESET to be held low in order to properly initialize and  
propagate default states at all I/O pins.  
4 The 4096 cycle count depends on tSRST specification in Table 12. If setup time is not met, 1 additional CLKIN cycle may be added to the core reset time, resulting in 4097  
cycles maximum.

CLKIN pin description in Table 3 on Page 11. The user applica-  
tion program can configure the ADSP-21364 to use its internal  
clock generator by connecting the necessary components to the  
CLKIN and XTAL pins. Figure 8 shows the component connec-  
tions used for a fundamental frequency crystal operating in  
parallel mode.  
Note that the clock rate is achieved using a 16.67 MHz crystal  
and a PLL multiplier ratio 16:1 (CCLK:CLKIN achieves a clock  
speed of 266.72 MHz). To achieve the full core clock rate, pro-  
grams need to configure the multiplier bits in the PMCTL

Serial Ports  
To determine whether 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) SCLK width.  
Serial port signals (SCLK, FS, data channel A, data channel B)  
are routed to the DAI_P20–1 pins using the SRU. Therefore, the  
timing specifications provided below are valid at the  
DAI_P20–1 pins.

For the serial output port, the frame-sync is an input and should  
meet setup and hold times with regard to SCLK on the output  
port. The serial data output, SDATA, has a hold time and delay  
specification with regard to SCLK. Note that SCLK rising edge is  
the sampling edge and the falling edge is the drive edge.

SPDIF Transmitter  
Serial data input to the SPDIF transmitter can be formatted as  
left-justified, I2S, or right-justified with word widths of 16, 18,  
20, or 24 bits. The following sections provide timing for the  
transmitter.  
SPDIF Transmitter—Serial Input Waveforms  
Figure 28 shows the right-justified mode. LRCLK is HI for the  
left channel and LO for the right channel. Data is valid on the  
rising edge of SCLK. The MSB is delayed 12-bit clock periods  
(in 20-bit output mode) or 16-bit clock periods (in 16-bit output  
mode) from an LRCLK transition, so that when there are 64  
SCLK periods per LRCLK period, the LSB of the data will be  
right-justified to the next LRCLK transition.

CAPACITIVE LOADING  
Figure 36 shows typical I-V characteristics for the output driv-  
ers of the ADSP-21364. The curves represent the current drive  
capability of the output drivers as a function of output voltage.  
Output delays and holds are based on standard capacitive loads:  
30 pF on all pins (see Figure 37). Figure 41 shows graphically  
how output delays and holds vary with load capacitance. The  
graphs of Figure 39, Figure 40, and Figure 41 may not be linear  
outside the ranges shown for Typical Output Delay vs. Load  
Capacitance and Typical Output Rise Time (20% to 80%, V =  
Min) vs. Load Capacitance.

The ADSP-21364 processor is rated for performance over the  
temperature range specified in Recommended Operating Con-  
ditions on Page 15.  
Table 39 through Table 42 airflow measurements comply with  
JEDEC standards JESD51-2 and JESD51-6 and the junction-to-  
board measurement complies with JESD51-8. Test board and  
thermal via design comply with JEDEC standards JESD51-9  
(BGA) and JESD51-5 (integrated heat sink LQFP). The junc-  
tion-to-case measurement complies with MIL-STD-883. All  
measurements use a 2S2P JEDEC test board.

Table 41. Thermal Characteristics for LQFP (With heat slug  
not soldered to PCB)  
Industrial applications using the BGA package require thermal  
vias, to an embedded ground plane, in the PCB. Refer to JEDEC  
standard JESD51-9 for printed circuit board thermal ball land  
and thermal via design information. Industrial applications  
using the LQFP package require thermal trace squares and ther-  
mal vias, to an embedded ground plane, in the PCB. The bottom  
side heat slug must be soldered to the thermal trace squares.  
Refer to JEDEC standard JESD51-5 for more information.
