Code Composer Studio is a trademark of Texas Instruments. The TMS470R1VF338, TMS470R1VF348, TMS470R1VF3382, and TMS470R1VF3482 High-end embedded control applications demand more performance from their controllers while maintaining low costs. The VF3x8x RISC core architecture offers solutions to these performance and cost demands while maintaining low power consumption. The VF338/VF348/VF3382/VF3482 device contains the following:
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; and parallel signature analysis (PSA). This data sheet includes devicespecific 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 VF3x8x 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. 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 F05 flash section of this data sheet and the TMS470R1x F05 Flash Reference Guide (literature number SPNU213). The VF3x8x device has six communication interfaces: two SPIs, two SCIs, an SCC, and a C2SIb. 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 VF3x8x to transmit and receive messages on a class II network following an SAE J1850 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 VF3x8x 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 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 The VF3x8x 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). |
