TMS570 Transportation and Safety Microcontrollers



ARM® Floating Point MCU Family for Transportation Applications

TMS570 Transportation MCUs are the industry’s first ARM® Cortex™-R4F based floating point MCUs that meet IEC61508/SIL3 safety standards. Targeted transportation safety applications include automotive chassis and stability control, electric power steering, hybrid and electric vehicles, aerospace, railway communications, and off-road vehicle engine control.

The TMS570 family integrates dual Cortex™-R4F processors in lock-step and is designed to meet automotive and transportation safety standards. These devices provide system-wide protection through seamless support for error detection from the processor, through the bus interconnect, and into the memories. The TMS570 development process and safety concept has been IEC61508/SIL3 certified by Exida, an independent 3rd party assessor.

TMS570 MCUs also have an integrated high-performance Floating Point Unit (FPU) which can provide both single and double precision. The FPU along with flexible control peripherals simplifies the development of real-time auto coded applications generated from physical based modeling tools.
