Description

The TMS470R1VF689/VF688⁽¹⁾ devices are members of the Texas Instruments TMS470R1x family of generalpurpose16/32-bit reduced instruction set computer (RISC) microcontrollers. The VF68x microcontroller offers 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 TMS470R1VF68x 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 VF68x RISC core architecture offers solutions to these performance and cost demands while maintaining low power consumption.

The VF68x devices contain the following:

• ARM7TDMI 16/32-Bit RISC CPU
• TMS470R1x system module (SYS) with 470+ enhancements
• 384K-byte Flash (VF689 only)
• 256K-byte Flash (VF688 only)
• 16K-byte SRAM (VF689 only)
• 12K-byte SRAM (VF688 only)
• Zero-pin phase-locked loop (ZPLL) clock module
• Analog watchdog (AWD) timer
• Enhanced real-time interrupt (RTI) module
• Two serial peripheral interface (SPI) modules
• Two serial communications interface (SCI) modules
• Two standard CAN controllers (SCC)
• Class II Serial Interface (C2SIb)
• Three inter-integrated circuit (I2C) modules
• 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), up to 51 I/O pins and 1 input-only pin (PZ Suffix)

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 VF68x has the option to be driven by the oscillator clock. This data sheet includes device-specific information such as memory and peripheral select assignment, interrupt priority, and a device memory map. For a more detailed functional description of the SYS module, see the TMS470R1x System Module Reference Guide (literature number SPNU189).

The VF68A 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 implemented with a 32-bit-wide data bus interface.The Flash operates with a system clock frequency of up to 24 MHz. When in pipeline mode, the Flash operates with a system clock frequency of up to 48 MHz. For more detailed information on the Flash, see the Flash section of this data sheet and the TMS470R1x F05 Flash Reference Guide (literature number SPNU213).

The VF68x device has ten communication interfaces: two SPIs, two SCIs, two SCCs, a C2SIb, and three I2Cs. 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 multiplexed wiring. The C2SIb allows the VF68xB to transmit and receive messages on a class II network following an SAE Standard J1850 Class B Data Communication Network Interface standard. The I2C module is a multi-master communication module providing an interface between the VF68x microcontroller and an I2Ccompatible device via the I2C serial bus. The I2C supports both 100 Kbps and 400 Kbps speeds. For more detailed functional information on the SPI, SCI, and SCC peripherals, see the specific reference guides (literature numbers SPNU195, SPNU196, and SPNU197). For more detailed functional information on the C2SIb peripheral, see the TMS470R1x Class II Serial Interface B (C2SIb) Reference Guide (literature number SPNU214). For more detailed functional information on the I2C, see the TMS470R1x Inter-Integrated Circuit (I2C) Reference Guide (literature number SPNU223).

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 VF68x 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 VF68x device has one 10-bit-resolution, sample-and-hold MibADC. Each of 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 can be triggered 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 MibADC, 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 VF68x 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).

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

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

The VF68x 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 peripheral interface clock (ICLK) frequency. For more detailed functional information on the ECP, see the TMS470R1x External Clock Prescaler (ECP) Reference Guide (literature number SPNU202).
