TMS470R1A384 100-Pin PZ Package (Top View)




DESCRIPTION

TMS470R1A384


The TMS470R1A384 (1) devices are members of the Texas Instruments TMS470R1x family of general-purpose16/32-bit reduced instruction set computer (RISC) microcontrollers. The A384 microcontroller offers highperformance utilizing the high-speed ARM7TDMI 16/32-bit RISC central processing unit (CPU), resulting in ahigh instruction throughput while maintaining greater code efficiency. The ARM7TDMI 16/32-bit RISC CPU viewsmemory as a linear collection of bytes numbered upwards from zero. The A384 utilizes the big-endian formatwhere the most significant byte of a word is stored at the lowest-numbered byte and the least significant byte atthe highest-numbered byte.

High-end embedded control applications demand more performance from their controllers while maintaining lowcosts. The A384 RISC core architecture offers solutions to these performance and cost demands whilemaintaining low power consumption.

The A384 devices contain the following:• ARM7TDMI 16/32-bit RISC CPU• TMS470R1x system module (SYS) with 470+ enhancements• 384K-byte flash• 32K-byte SRAM• Zero-pin phase-locked loop (ZPLL) clock module• Analog watchdog (AWD) timer• Enhanced real-time interrupt (RTI) module• Interrupt expansion module (IEM)• Two serial peripheral interface (SPI) modules• Two serial communications interface (SCI) modules• Two standard CAN controllers (SCC)• Three inter-integrated circuit (I2C) modules• Class II serial interface B (C2SIb) module• 10-bit multi-buffered analog-to-digital converter (MibADC), with 12 input channels• High-end timer (HET) controlling 12 I/Os• External clock prescale (ECP)• Expansion bus module (EBM)• Up to 87 I/O pins and 1 input-only pin (PGE suffix only), up to 51 I/O pins and 1 input-only pin (PZ suffix only)

The functions performed by the 470+ system module (SYS) include:• Address decoding• Memory protection• Memory and peripherals bus supervision• Reset and abort exception management• Prioritization for all internal interrupt sources• Device clock control• Parallel signature analysis (PSA)

The enhanced real-time interrupt (RTI) module on the A384 has the option to be driven by the oscillator clock.This data sheet includes device-specific information such as memory and peripheral select assignment, interruptpriority, and a device memory map. For a more detailed functional description of the SYS module, see theTMS470R1x System Module Reference Guide (literature number SPNU189).

The A384 memory includes general-purpose SRAM supporting single-cycle read/write accesses in byte,half-word, and word modes.

The flash memory on this device is a nonvolatile, electrically erasable and programmable memory implementedwith a 32-bit-wide data bus interface. The flash operates with a system clock frequency of up to 24 MHz. Whenin pipeline mode, the flash operates with a system clock frequency of up to 48 MHz. For more detailedinformation on the flash, see the Flash section of this data sheet and the TMS470R1x F05 Flash ReferenceGuide (literature number SPNU213).(1) Throughout the remainder of this document, the TMS470R1A384 is referred to as either the full device name or as A384.




TMS470R1A384


The A384 device has ten communication interfaces: two SPIs, two SCIs, two SCCs, a C2SI, and three I2Cs. TheSPI provides a convenient method of serial interaction for high-speed communications between similarshift-register type devices. The SCI is a full-duplex, serial I/O interface intended for asynchronous communicationbetween the CPU and other peripherals using the standard non-return-to-zero (NRZ) format. The SCC uses aserial, multimaster communication protocol that efficiently supports distributed real-time control with robustcommunication rates of up to 1 megabit per second (Mbps). The SCC is ideal for applications operating in noisyand harsh environments (e.g., industrial fields) that require reliable serial communication or multiplexed wiring.The C2SIb allows the A384 to transmit and receive messages on a class II network following an SAE J1850 (2)standard. The I2C module is a multi-master communication module providing an interface between the A384microcontroller and an I2C-compatible device via the I2C serial bus. The I2C supports both 100 Kbps and400 Kbps speeds. For more detailed functional information on the SPI, SCI, and CAN peripherals, see thespecific reference guides (literature numbers SPNU195, SPNU196, and SPNU197). For more detailed functionalinformation on the I2C, see the TMS470R1x Inter-Integrated Circuit (I2C) Reference Guide (literature numberSPNU223). For more detailed functional information on the C2SI, see the TMS470R1x Class II Serial Interface B(C2SIb) Reference Guide (literature number SPNU214).

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 anattached I/O port. The HET can be used for compare, capture, or general-purpose I/O. It is especially well suitedfor applications requiring multiple sensor information and drive actuators with complex and accurate time pulses.The HET used in this device is the high-end timer lite. It has fewer I/Os than the usual 32 in a standard HET. Formore detailed functional information on the HET, see the TMS470R1x High-End Timer (HET) Reference Guide(literature number SPNU199).

The A384 HET peripheral contains the XOR-share feature. This feature allows two adjacent HET high- resolutionchannels to be XORed together, making it possible to output smaller pulses than a standard HET. For moredetailed information on the HET XOR-share feature, see the TMS470R1x High-End Timer (HET) ReferenceGuide (literature number SPNU199).

The A384 device has one 10-bit-resolution sample-and-hold MibADC. Each of the MibADC channels can beconverted individually or can be grouped by software for sequential conversion sequences. There are threeseparate groupings, two of which can be triggered by an external event. Each sequence can be converted oncewhen triggered or configured for continuous conversion mode. For more detailed functional information on theMibADC, see the TMS470R1x Multi-Buffered Analog-to-Digital Converter (MibADC) Reference Guide (literaturenumber SPNU206).

The zero-pin phase-locked loop (ZPLL) clock module contains a phase-locked loop, a clock-monitor circuit, aclock-enable circuit, and a prescaler (with prescale values of 1–8). The function of the ZPLL is to multiply theexternal 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 A384 device modules. For moredetailed functional information on the ZPLL, see the TMS470R1x Zero-Pin Phase-Locked Loop (ZPLL) ClockModule Reference Guide (literature number SPNU212).

NOTE:

ACLK should not be confused with the MibADC internal clock, ADCLK. ACLK is thecontinuous system clock from an external resonator/crystal reference.

The expansion bus module (EBM) is a stand-alone module that supports the multiplexing of the GIO functionsand the expansion bus interface. For more information on the EBM, see the TMS470R1x Expansion Bus Module(EBM) Reference Guide (literature number SPNU222).

The A384 device also has an external clock prescaler (ECP) module that, when enabled, outputs a continuousexternal clock (ECLK) on a specified GIO pin. The ECLK frequency is a user-programmable ratio of theperipheral interface clock (ICLK) frequency. For more detailed functional information on the ECP, see theTMS470R1x External Clock Prescaler (ECP) Reference Guide (literature number SPNU202).

(2) SAE Standard J1850 Class B Data Communication Network Interface.

Figure 1. TMS470R1A384 Memory Map




Memory Selects

TMS470R1A384


Memory selects allow the user to address memory arrays (i.e., flash, RAM, and HET RAM) at user-definedaddresses. Each memory select has its own set (low and high) of memory base address registers (MFBAHRxand MFBALRx) that, together, define the array's starting (base) address, block size, and protection.

The base address of each memory select is configurable to any memory address boundary that is a multiple ofthe decoded block size. For more information on how to control and configure these memory select registers, seethe bus structure and memory sections of the TMS470R1x System Module Reference Guide (literature numberSPNU189).

For the memory selection assignments and the memory selected, see Table 3.

Table 3. TMS470R1A384 Memory Selection AssignmentMEMORY MEMORY SELECTED MEMORY STATIC MEMMPU MEMORY BASE ADDRESS REGISTERSELECT (ALL INTERNAL) SIZE (1) CTL REGISTER

(1) x8 refers to size of memory in 8-bits; x16 refers to size of memory in 16-bits.(2) The starting addresses for both RAM memory-select signals cannot be offset from each other by a multiple of the user-defined block

size in the memory-base address register.

RAMThe A384 device contains 32K-bytes of internal static RAM configurable by the SYS module to be addressedwithin the range of 0x0000_0000 to 0xFFE0_0000. This A384 RAM is implemented in one 32K-byte arrayselected by two memory-select signals.

NOTE:

This A384 configuration imposes an additional constraint on the memory map forRAM; the starting addresses for both RAM memory selects cannot be offset fromeach other by the multiples of the size of the physical RAM (i.e., 32K bytes for theA384 device). The A384 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 userfiner blocks of memory protection than is allowed by the memory selects. The MPU is ideal for protecting anoperating system while allowing access to the current task. For more detailed information on the MPU portion ofthe SYS module and memory protection, see the memory section of the TMS470R1x System Module ReferenceGuide (literature number SPNU189).




TMS470R1A384


F05 FlashThe F05 flash memory is a nonvolatile electrically erasable and programmable memory implemented with a32-bit-wide data bus interface. The F05 flash has an external state machine for programming and erasefunctions. See the Flash Read and Flash Program and Erase sections.

Flash Protection Keys

The A384 device provides flash protection keys. These four 32-bit protection keys preventprogram/erase/compaction operations from occurring until after the four protection keys have been matched bythe CPU loading the correct user keys into the FMPKEY control register. The protection keys on the A384 arelocated in the last 4 words of the first 8K sector. For more detailed information on the flash protection keys andthe FMPKEY control register, see the "Optional Quadruple Protection Keys" and "Programming the ProtectionKeys" portions of the TMS470R1x F05 Flash Reference Guide (literature number SPNU213).

Flash Read

The A384 flash memory is configurable by the SYS module to be addressed within the range of 0x0000_0000 to0xFFE0_0000. The flash is addressed through memory selects 0 and 1.

NOTE:

The flash external pump voltage (VCCP) is required for all operations (program, erase,and read).

Flash Pipeline Mode

When in pipeline mode, the flash operates with a system clock frequency of up to 48 MHz (versus a systemclock frequency of 24 MHz in normal mode). Flash in pipeline mode is capable of accessing 64-bit words andprovides two 32-bit pipelined words to the CPU. Also, in pipeline mode the flash can be read with no wait stateswhen memory addresses are contiguous (after the initial 1- or 2-wait-state reads).

NOTE:

After a system reset, pipeline mode is disabled (FMREGOPT[0] = 0). In other words,the A384 device powers up and comes out of reset in non-pipeline mode.Furthermore, setting the flash configuration mode bit (GBLCTRL[4]) overrides pipelinemode.




Peripheral Selects and Base Addresses

Flash Program and Erase

The A384 device flash contains three 128K-byte memory arrays (or banks), for a total of 384K-bytes of flash, andconsists of 18 sectors. These 18 sectors are sized as follows:

(128K Bytes)2 32K Bytes 0x0005_0000 0x0005_7FFF3 32K Bytes 0x0005_8000 0x0005_FFFF

The minimum size for an erase operation is one sector. The maximum size for a program operation is one 16-bitword.

NOTE:

The flash external pump voltage (VCCP) is required for all operations (program, erase,and read).

Execution can occur from one bank while programming/erasing any or all sectors of another bank. However,execution cannot occur from any sector within a bank that is being programmed or erased.

NOTE:

When the OTP sector is enabled, the rest of the flash memory is disabled. The OTPmemory can only be read or programmed from code executed out of RAM.

For more detailed information on flash program and erase operations, see the TMS470R1x F05 Flash ReferenceGuide (literature number SPNU213).

HET RAMThe A384 device contains HET RAM. The HET RAM has a 64-instruction capability. The HET RAM isconfigurable by the SYS module to be addressed within the range of 0x0000_0000 to 0xFFE0_0000. The HETRAM is addressed through memory select 4.

The A384 device uses 10 of the 16 peripheral selects to decode the base addresses of the peripherals. Theseperipheral selects are fixed and transparent to the user because they are part of the decoding scheme used bythe SYS module.

Control registers for the peripherals, SYS module, and flash begin at the base addresses shown in Table 4.

Direct Memory Access (DMA)

TMS470R1A384


The DMA controller transfers data to and from any specified location in the A384 memory map (except forrestricted memory locations like the system control registers area). The DMA manages up to 16 channels, andsupports data transfer for both on-chip and off-chip memories and peripherals. The DMA controller is connectedto both the CPU and peripheral buses, enabling these data transfers to occur in parallel with CPU activity and,thus, maximizing overall system performance.

Although the DMA controller has two possible configurations for the A384 device, the DMA controllerconfiguration is 32 control packets and 16 channels.

For the A384 DMA request hardwired configuration, see Table 5.

(1) For DMA channels with more than one assigned request source (I2C2/C2SIb), only one of the sources listed can be the DMA requestgenerator in a given application. The device has software control to ensure that there are no conflicts between requesting modules.

Each channel has two control packets attached to it, allowing the DMA to continuously load RAM and generateperiodic interrupts so that the data can be read by the CPU. The control packets allow for the interrupt enable,and the channels determine the priority level of the interrupt.

DMA transfers occur in one of two modes:• Non-request mode (used when transferring from memory to memory)• Request mode (used when transferring from memory to peripheral)

For more detailed functional information on the DMA controller, see the TMS470R1x Direct Memory Access(DMA) Controller Reference Guide (literature number SPNU194).




Interrupt Priority (IEM to CIM)

TMS470R1A384


Interrupt requests originating from the A384 peripheral modules (i.e., SPI1 or SPI2, SCI1 or SCI2, RTI, etc.) areassigned to channels within the 48-channel interrupt expansion module (IEM) where, via programmable registermapping, these channels are then mapped to the 32-channel central interrupt manager (CIM) portion of the SYSmodule.

Programming multiple interrupt sources in the IEM to the same CIM channel effectively shares the CIM channelbetween sources.

The CIM request channels are maskable so that individual channels can be selectively disabled. All interruptrequests can be programmed in the CIM to be of either type:• Fast interrupt request (FIQ)• Normal interrupt request (IRQ)

The CIM prioritizes interrupts. The precedences of request channels decrease with ascending channel order inthe CIM [0 (highest) and 31 (lowest) priority]. For IEM-to-CIM default mapping, channel priorities, and theirassociated modules, see Table 6.

Expansion Bus Module (EBM)

TMS470R1A384


The expansion bus module (EBM) is a standalone module used to bond out both general-purpose input/outputpins and expansion bus interface pins. The module supports 8- and 16-bit expansion bus memory interfacemappings, as well as mapping of the following expansion bus signals:• 22-bit address bus (EBADDR[21:0]) for x8, 19-bit address bus (EBADDR[18:0]) for x16• 8- or 16-bit data bus (EBDATA[7:0]or EBDATA[15:0])• Two write strobes (EBWR[1:0])• Two memory chip selects (EBCS[6:5])• One output enable (EBOE)• One external hold signal for interfacing to slow memories (EBHOLD)

Table 7 shows the multiplexing of I/O signals with the expansion bus interface signals. The mapping of thesepins varies depending on the memory mode.

MibADC

TMS470R1A384


The multi-buffered analog-to-digital converter (MibADC) accepts an analog signal and converts the signal to a10-bit digital value.

The A384 MibADC module can function in two modes: compatibility mode, where its programmer's model iscompatible with the TMS470R1x ADC module and its digital results are stored in digital result registers; or inbuffered mode, where the digital result registers are replaced with three FIFO buffers, one for each conversiongroup [event, group1 (G1), and group2 (G2)]. In buffered mode, the MibADC buffers can be serviced byinterrupts or by the DMA.

NOTE:

The MibADC on this device does not support the DMA.

MibADC Event Trigger EnhancementsThe MibADC includes two major enhancements over the event-triggering capability of the TMS470R1x ADC.• 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 group1 and the event group from the

options identified in Table 9.

For group1, these event-triggered selections are configured via the group1 source select bits (G1SRC[1:0]) in theAD event source register (ADEVTSRC[5:4]). For the event group, these event-triggered selections are configuredvia the event group source select bits (EVSRC[1:0]) in the AD event source register (ADEVTSRC[1:0]).

Device and Development-Support Tool Nomenclature

TMS470R1A384


To designate the stages in the product development cycle, TI assigns prefixes to the part numbers of all DSPdevices and support tools. Each DSP commercial family member has one of three prefixes: TMX, TMP, or TMS(e.g., TMS470R1A384). Texas Instruments recommends two of three possible prefix designators for its supporttools: TMDX and TMDS. These prefixes represent evolutionary stages of product development from engineeringprototypes (TMX/TMDX) through fully qualified production devices/tools (TMS/TMDS).

Device development evolutionary flow:

TMX Experimental device that is not necessarily representative of the final device's electrical specificationsTMP Final silicon die that conforms to the device's electrical specifications but has not completed quality and

reliability verification

TMS Fully qualified production deviceSupport tool development evolutionary flow:

TMDX Development-support product that has not yet completed Texas Instruments internal qualification testing.TMDS Fully qualified development-support productTMX and TMP devices and TMDX development-support tools are shipped against the following disclaimer:

"Developmental product is intended for internal evaluation purposes."

TMS devices and TMDS development-support tools have been characterized fully, and the quality and reliabilityof the device have been demonstrated fully. TI's standard warranty applies.

Predictions show that prototype devices (TMX or TMP) have a greater failure rate than the standard productiondevices. Texas Instruments recommends that these devices not be used in any production system because theirexpected end-use failure rate still is undefined. Only qualified production devices are to be used.

Figure 3 illustrates the numbering and symbol nomenclature for the TMS470R1x family.
