The TMS5703137CZWTQQ1 is a 32-bit high-performance automotive-grade RISC flash Microcontroller for safety systems. The safety architecture includes dual CPUs in lockstep, CPU and memory BIST logic, ECC on both the flash and the data SRAM, parity on peripheral memories and loopback capability on peripheral I/Os. The device integrates the ARM Cortex-R4F floating-point CPU which offers an efficient 1.66 DMIPS/MHz and has configurations which can run up to 180MHz providing up to 298 DMIPS. The device supports the word-invariant big-endian [BE32] format. The TMS570LS3137 device has 3MB of integrated flash and 256kB of data RAM. Both the flash and RAM have single-bit error correction and double-bit error detection. The flash memory on this device is a non-volatile, 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.
