1.2 Description
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 ARM® Cortex™-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.
The TMS570LS devices feature peripherals for real-time control-based applications, including up to 32
nHET timer channels and two 12-bit A to D converters supporting up to 24 inputs. There are multiple
communication interfaces including a 2-channel FlexRay, 3 CAN controllers supporting 64 mailboxes
each, and 2 LIN/UART controllers.
With integrated SIL3 certified safety features and a wide choice of communication and control peripherals,
the TMS570LS series is an ideal solution for high performance real time control applications with safety
critical requirements.
