description
†
The TMS470R1VC336 and TMS470R1VC346 devices are members of the Texas Instruments TMS470R1x
family of general-purpose16/32-bit reduced instruction set computer (RISC) microcontrollers. These microcon-
trollers offer high performance utilizing the high-speed ARM7TDMI 16/32-bit RISC central processing unit
(CPU), resulting in a high instruction throughput while maintaining greater code efficiency. The ARM7TDMI 16/
32-bit RISC CPU views memory as a linear collection of bytes numbered upwards from zero. The
TMS470R1VC3x6 utilizes the big-endian format, where the most significant byte of a word is stored at the
lowest numbered byte and the least significant byte at the highest numbered byte.
High-end embedded control applications demand more performance from their controllers while maintaining
low costs. The VC3x6 RISC core architecture offers solutions to these performance and cost demands while
maintaining low power consumption.

description (continued)
The VC3x6 device has six communication interfaces: two SPIs, two SCIs, an SCC, and a C2SIa. The SPI
provides a convenient method of serial interaction for high-speed communications between similar shift-register
type devices. The SCI is a full-duplex, serial I/O interface intended for asynchronous communication between
the CPU and other peripherals using the standard Non-Return-to-Zero (NRZ) format. The SCC uses a serial,
multimaster communication protocol that efficiently supports distributed real-time control with robust
communication rates of up to 1 megabit per second (Mbps). The SCC is ideal for applications operating in noisy
and harsh environments (e.g., automotive and industrial fields) that require reliable serial communication or
multiplexedwiring. TheC2SIaallowstheVC3x6totransmitandreceivemessagesonaclassIInetworkfollowing

an SAE J1850 standard. For more detailed functional information on the SPI, SCI, and SCC peripherals, see
the specific TMS470R1x Peripheral Reference Guides (literature numbers SPNU195, SPNU196, and
SPNU197, respectively). For more detailed functional information on the C2SIa peripheral, see the TMS470R1x
Class II Serial Interface A (C2SIa) Reference Guide (literature number SPNU218).
The HET is an advanced intelligent timer that provides sophisticated timing functions for real-time applications.
The timer is software-controlled, using a reduced instruction set, with a specialized timer micromachine and
an attached I/O port. The HET can be used for compare, capture, or general-purpose I/O. It is especially well
suited for applications requiring multiple sensor information and drive actuators with complex and accurate
time pulses. For more detailed functional information on the HET, see the TMS470R1x High-End Timer (HET)
Reference Guide (literature number SPNU199). The VC3x6 HET peripheral contains the XOR-share feature.
This feature allows two adjacent HET high-resolution channels to be XORed together, making it possible to
output smaller pulses than a standard HET. For more detailed information on the HET XOR-share feature, see
the TMS470R1x High-End Timer (HET) Reference Guide (literature number SPNU199).
The VC3x6 device has a 10-bit-resolution sample-and-hold MibADC. The MibADC channels can be converted
individually or can be grouped by software for sequential conversion sequences. There are three separate
groupings, two of which are triggerable by an external event. Each sequence can be converted once when
triggered or configured for continuous conversion mode. For more detailed functional information on the Mi-
bADC, see the TMS470R1x Multi-Buffered Analog-to-Digital Converter (MibADC) Reference Guide (literature
number SPNU206).
The zero-pin phase-locked loop (ZPLL) clock module contains a phase-locked loop, a clock-monitor circuit, a
clock-enable circuit, and a prescaler (with prescale values of 1–8). The function of the ZPLL is to multiply the
‡
external frequency reference to a higher frequency for internal use. The ZPLL provides ACLK to the system
(SYS) module. The SYS module subsequently provides system clock (SYSCLK), real-time interrupt clock
(RTICLK), CPU clock (MCLK), and peripheral interface clock (ICLK) to all other VC3x6 device modules. For
more detailed functional information on the ZPLL, see the TMS470R1x Zero-Pin Phase-Locked Loop (ZPLL)
Clock Module Reference Guide (literature number SPNU212).
The VC3x6 device also has an external clock prescaler (ECP) module that when enabled, outputs a continuous
external clock (ECLK) on a specified GIO pin. The ECLK frequency is a user-programmable ratio of the pe-
ripheral interface clock (ICLK) frequency. For more detailed functional information on the ECP, see the
TMS470R1x External Clock Prescaler (ECP) Reference Guide (literature number SPNU202).
device characteristics
The TMS470R1VC3x6 device is a derivative of the F05 system emulation device SE470R1VB8AD. Table 1
identifies all the characteristics of the TMS470R1VC3x6 device except the SYSTEM and CPU, which are
generic. The COMMENTS column aids the user in software-programming and references device-specific in-
formation.
† SAE Standard J1850 Class B Data Communication Network Interface
‡ ACLK should not be confused with the MibADC internal clock, ADCLK. ACLK is the continuous system clock from an external resonator/crystal
reference.

memory selects
Memory selects allow the user to address memory arrays (i.e., ROM, RAM, and HET RAM) at user-defined
addresses. Each memory select has its own set (low and high) of memory base address registers (MFBAHRx
and MFBALRx) that, together, define the array’s starting (base) address, size, and protection.
The base address of each memory select is configurable to any memory address boundary that is a multiple
of the decoded block size. The decoded block size for the ROM memory on this device is 0x00100000. For
more information on how to control and configure these memory select registers, see the bus structure and
memory sections of the TMS470R1x System Module Reference Guide (literature number SPNU189).

RAM
The VC3x6 device contains 8K bytes of internal static RAM configurable by the SYS module to be addressed
within the range of 0x0000_0000 to 0xFFE0_0000. This VC3x6 RAM is implemented in one 8K array selected
by two memory-select signals. These configurations impose an additional constraint on the memory map for
RAM; the starting addresses for both RAM memory selects cannot be offset from each other by the multiples
of the size of the physical RAM (i.e., 8K for the VC3x6 device). The VC3x6 RAM is addressed through memory
selects 2 and 3.
The RAM can be protected by the memory protection unit (MPU) portion of the SYS module, allowing the user
finer blocks of memory protection than is allowed by the memory selects. The MPU is ideal for protecting an
operating system while allowing access to the current task. For more detailed information on the MPU portion
of the SYS module and memory protection, see the memory section of the TMS470R1x System Module
Reference Guide (literature number SPNU189).
ROM
The VC3x6 program ROM consists of 128K bytes mask programmable read-only memory. The program ROM
is used for permanent storage of data or instructions. Programming the mask ROM is performed at the time of
device fabrication.
HET RAM
The VC3x6 device contains HET RAM. The HET RAM has a 64-instruction capability. The HET RAM is con-
figurable by the SYS module to be addressed within the range of 0x0000_0000 to 0xFFE0_0000. The HET
RAM is addressed through memory select 4.

peripheral selects and base addresses
The VC3x6 device uses ten of the sixteen peripheral selects to decode the base addresses of the peripherals.
These peripheral selects are fixed and transparent to the user since they are part of the decoding scheme used
by the SYS module.

interrupt priority
The central interrupt manager (CIM) portion of the SYS module manages the interrupt requests from the device
modules (i.e., SPI1 or SPI2, SCI1 or SCI2, and RTI, etc.).
Although the CIM can accept up to 32 interrupt request signals, the VC3x6 device only uses 21 of those interrupt
request signals. The request channels are maskable so that individual channels can be selectively disabled.
All interrupt requests can be programmed in the CIM to be of either type:
z
z
Fast interrupt request (FIQ)
Normal interrupt request (IRQ)
The precedences of request channels decrease with ascending channel order in the CIM (0 [highest] and
31 [lowest] priority). For these channel priorities and the associated modules, see Table 4.

MibADC
The multi-buffered analog-to-digital converter (MibADC) accepts an analog signal and converts the signal to a
10-bit digital value.
The VC3x6 MibADC module can function in two modes: compatibility mode, where its programmer’s model is
compatible with the TMS470R1x ADC module and its digital results are stored in digital result registers; or in
buffered mode, where the digital result registers are replaced with three FIFO buffers, one for each conversion
group[event, group1(G1), andgroup2(G2)]. Inbufferedmode, theMibADCbufferscanbeservicedbyinterrupts
or by the DMA.
MibADC event trigger enhancements
The MibADC includes two major enhancements over the event-triggering capability of the TMS470R1x ADC.
z
z
Both group1 and the event group can be configured for event-triggered operation, providing up to two event-
triggered groups.
The trigger source and polarity can be selected individually for both group 1 and the event group from the
three options identified in Table 5.

external reference resonator/crystal oscillator clock option
The oscillator is enabled by connecting the appropriate fundamental 4–20 MHz resonator/crystal and load
capacitors across the external OSCIN and OSCOUT pins as shown in Figure 4a. The oscillator is a single-
stage inverter held in bias by an integrated bias resistor. This resistor is disabled during leakage test measure-
ment and HALT mode. TI strongly encourages each customer to submit samples of the device to the
resonator/crystal vendors for validation. The vendors are equipped to determine what load capacitors will
best tune their resonator/crystal to the microcontroller device for optimum start-up and operation over temper-
ature/voltage extremes.
An external oscillator source can be used by connecting a 1.8 V clock signal to the OSCIN pin and leaving the
OSCOUT pin unconnected (open) as shown in Figure 4b.

† X = {1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16}. X is the interface clock divider ratio determined by the PCR0.[4:1] bits in the SYS module.
‡ N = {1 to 256}. N is the ECP prescale value defined by the ECPCTRL.[7:0] register bits in the ECP module.
§ CLKOUT/ECLK pulse durations (low/high) are a function of the OSCIN pulse durations when PLLDIS is active.

high-end timer (HET) timings
minimum PWM output pulse width:
This is equal to one High Resolution Clock Period (HRP). The HRP is defined by the 6-bit High Resolution
Prescale Factor (hr) which is user defined, giving prescale factors of 1 to 64, with a linear increment of codes.
Therefore, the minimum PWM output pulse width = HRP(min) = hr(min)/SYSCLK = 1/SYSCLK
For example, for a SYSCLK of 30 MHz, the minimum PWM output pulse width = 1/30 = 33.33ns
minimum input pulses we can capture:
The input pulse width must be greater or equal to the Low Resolution Clock Period (LRP), i.e., the HET loop
(the HET program must fit within the LRP). The LRP is defined by the 3-bit Loop-Resolution Prescale Factor
(lr), which is user defined, with a power of 2 increment of codes. That is, the value of lr can be 1, 2, 4, 8, 16, or 32.
Therefore, the minimum input pulse width = LRP(min) = hr(min) * lr(min)/SYSCLK = 1 * 1/SYSCLK
For example, with a SYSCLK of 30 MHz, the minimum input pulse width = 1 * 1/30 = 33.33 ns
Note: Once the input pulse width is greater than LRP, the resolution of the measurement is still HRP. (That is,
the captured value gives the number of HRP clocks inside the pulse.)
Abbreviations:
High resolution clock period = HRP = hr/SYSCLK
Loop resolution clock period = LRP = hr*lr/SYSCLK
hr = HET high resolution divide rate = 1, 2, 3,...63, 64
lr = HET low resolution divide rate = 1, 2, 4, 8, 16, 32

multi-buffered A-to-D converter (MibADC)
The multi-buffered A-to-D converter (MibADC) has a separate power bus for its analog circuitry that enhances
the A-to-D performance by preventing digital switching noise on the logic circuitry which could be present on
V
and V
from coupling into the A-to-D analog stage. All A-to-D specifications are given with respect to
