The TMS570LS series is a high performance automotive grade microcontroller family which has been certified for use in IEC 61508 SIL3 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 TMS570LS family integrates the ARMç Cortexâ-R4F Floating Point CPU which offers an efficient 1.6 DMIPS/MHz, and has configurations which can run up to 160 MHz providing more than 250 DMIPS. The TMS570LS series also provides different Flash (1MB or 2MB) and data SRAM (128KB or 160KB) options with single bit error correction and double bit error detection.
