TMS570 Product Overview[edit]

ARM® based 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 and Cortex-R5F 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. More information can be found at the TMS570LS ARM CortexR4F Series Overview.

Safety[edit]

Real-Time Safety Architecture

The TMS570 Family of MCUs is based on dual Cortex-R4F or dual Cortex-R5F processors in lock-step, these new devices are designed to meet safety standard requirements and provide system-wide protection through seamless support for error detection from the processor, through the interconnect and into the memories. TI recognizes that no single safety concept is optimal for all systems. Lockstep and AMP approaches give customers flexible options for system implementation to achieve IEC61508/SIL3 and ISO 26262 ASIL-C/D' -->safety standards.
