RM4x/RM57 Product Overview[edit]

ARM® Cortex®-R Based Safety MCU's for Industrial and Medical Applications

The Hercules RM4x/RM57 Safety MCU family enables customers to easily develop safety critical industrial and medical applications. The ARM® Cortex®-R4F core in the RM4x series offers up to 220MHz of floating point performance, more than 350 DMIPS. The ARM® Cortex®-R5F core in the RM57L852 controller offers up to 330MHz of floating point performance, more than 500 DMIPS. With integrated safety features, advanced connectivity options, and flexible real-time control peripherals, the RM4x/RM57 family is an ideal solution for industrial applications with specific safety requirements.

Safety[edit]

Real-Time Safety Architecture

The RM4 family of MCUs is based on dual Cortex™-R4F processors in lock-step, these devices are designed to meet error-free safety standards 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 safety standards.
