Texas Instruments: TMDX570LS31USB Development Kit

Kit Overview

The TMS570LS31xTMS570LS31x Hercules USB Development Stick is ideal for evaluating the Hercules platform of safety microcontrollers. The USB Stick features an integrated XDS100v2 JTAG emulator, access to several key peripheral pins and is completely powered by a PC’s USB port. The kit also contains a quick start guide, a USB extension cable, a LED flashlight and a software installation DVD that includes Code Composer Studio IDE, HALCoGen, nowFlash, HET IDE, demo software and code examples.

The TMS570LS3137 is a high performance automotive grade microcontroller family for safety systems. The safety architecture includes Dual CPUs in lockstep, CPU and Memory Built-In Self Test (BIST) logic, ECC on both the Flash and the data SRAM, parity on peripheral memories, and loop back capability on peripheral IOs. The TMS570LS3137 integrates the ARM Cortex-R4F Floating Point CPU which offers an efficient 1.6 DMIPS/MHz, and has configurations which can run up to 180MHz providing up to 288 DMIPS. The device supports the big-endian [BE32] format.

The TMS570LS3137 has up to 3MB integrated Flash and up to 256KB data RAM configurations with single bit error correction and double bit error detection. The flash memory on this device is a nonvolatile, electrically erasable and programmable memory implemented with a 64-bit-wide data bus interface. The flash operates on a 3.3V supply input (same level as I/O supply) for all read, program and erase operations. When in pipeline mode, the flash operates with a system clock frequency of up to 180MHz. The SRAM supports single-cycle read/write accesses in byte, halfword, and word modes.

Key Applications: Braking systems (ABS and ESC), Electric power steering (EPS), HEV/EV inverter systems, Battery management systems, Active driver assistance systems, Aerospace and avionics, Railway communications, Railway communications, Off road vehicles.
