Hercules™ safety microcontrollers are based on Texas Instrument's 20+ years of safety-critical system expertise, industry collaboration and proven hardware for the automotive market. The platform consists of three ARM® Cortex™-based microcontroller families (RM4, TMS570 and TMS470M) that deliver scalable performance, connectivity, memory and safety features. Unlike many microcontrollers that rely heavily on software for safety capabilities, Hercules™ microcontrollers implement safety in hardware to maximize performance and reduce software overhead.

Applications:

RM4 ARM Cortex-R4F

The Hercules™ RM4x Safety MCU family enables customers to easily develop safety critical industrial and medical applications. Developed to meet the requirements the IEC 61508 SIL-3 safety standard, the ARM® Cortex™-R4F based RM48x offers up to 220MHz of floating point performance providing more than 350 DMIPS. With integrated safety features, advanced connectivity options, and flexible real-time control peripherals, the RM4x family is an ideal solution for industrial and medical applications with specific safety requirements.

Key Applications:

  • Industrial Automation
  • Safe PLC's (Programmable Logic Controllers)
  • Power Generation & Distribution
  • Turbines & Windmills
  • Ventilators & Defibrillators
  • Infusion & Insulin pumps
  • Radiation therapy

TMS470M ARM Cortex-M3 Series

The Hercules™ TMS470M microcontroller family enables developers to easily create safety-related applications for the transportation industry. The TMS470M value-line microcontrollers use the ARM® Cortex™-M3 CPU running at 80MHz and offer Flash memory options ranging from 256KB to 640KB (including up to 128KB EEPROM emulation capability) and RAM memory ranging from 16KB to 64KB. With built-in safety features like CPU and RAM self test (BIST) engines, error correction code (ECC) and parity-checking, the devices are a great extension to the Hercules Safety MCU platform.

Key Applications:

  • Electric power steering (EPS)
  • Braking systems (ABS and ESC)
  • Safety-related automotive
  • Automotive Infrastructure
  • Commercial Vehicles
  • Off-road vehicles
  • Airbags, electric park brake, safe communication, parking assist
