TI Hercules TMS570LS12x/11x and RM46x microcontrollers

Texas Instruments (TI) has announced that its Hercules TMS570LS12x/11x and RM46x microcontrollers (MCUs) are certified by TÜV SÜD to meet the relevant requirements of ISO 26262:2011 and IEC 61508:2010 functional safety standards to ASIL D and SIL 3 levels of safety integrity.

The Hercules TMS570LS12x/11x MCUs help developers create functional-safety-related applications for the automotive and transportation industry, offering frequencies up to 180 MHz. The automotive-qualified MCUs offer a variety of performance, memory and peripheral options to help meet a range of system needs.

The high-performance Hercules RM46x MCUs meanwhile support industrial and general-purpose functional-safety-related applications and offer frequencies up to 220 MHz. They provide various performance and memory configurations as well as targeted motor control capabilities.

The company’s MCUs integrate diagnostic features that detect and respond to runtime faults and help establish a ‘safe island’ to perform safety-critical processing without significant software overhead. Integrated diagnostics include dual ARM Cortex-R4 floating-point CPUs in lockstep; CPU and SRAM built-in-self-test (BIST); and transaction-based error correction codes (ECC) on the flash and RAM interfaces and memory, which can detect dual-bit faults and correct single-bit faults.
