TMS570LS1227 is a 16- and 32-Bit RISC Flash Microcontroller

This post sponsored by Texas Instruments.

The TMS570LS1227 device is a high-performance automotive-grade microcontroller family 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 TMS570LS1227 device integrates the ARM Cortex-R4F floating-point CPU, which offers an efficient 1.66 DMIPS/MHz and has configurations that can run up to 180 MHz. It supports the word-invariant big-endian [BE32] format. The TMS570LS1227 device has 1.25MB of integrated flash and 192KB of data RAM 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 3.3-V supply input for all read, program, and erase operations. The TMS570LS1227 device features peripherals for real-time control-based applications, including two Next Generation High-End Timer timing coprocessors with up to 44 I/O terminals, seven Enhanced Pulse Width Modulator modules with up to 14 outputs, six Enhanced Capture modules, two Enhanced Quadrature Encoder Pulse modules, and two 12-bit Analog-to-Digital Converters supporting up to 24 inputs.
