TMS570LS1227 datasheet



The TMS570LS1227 device is a high-performance automotive-grade microcontroller family for safety systems. The safety architecture includes the following:

• 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

• 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 180 MHz providing up to 298 DMIPS. The device supports the word-invariant big-endian [BE32] format.


1. Dual CPUs Running in Lockstep

2. ECC on Flash and RAM Interfaces

3. Built-In Self-Test (BIST) for CPU and On-chip RAMs

4. Error Signaling Module With Error Pin
