Hercules safety microcontrollers are based on TI’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 (RM48x, 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 hardwareto maximize performance and reduce software overhead.
The Hercules RM4x family provides
the highest level of performance
for broad safety applications,
including medical and industrial,
and are developed to the
IEC 61508 SIL-3 safety standard.
The Hercules TMS570 family provides high performance for transportation applications and is very well suited for applications that need to meet IEC 61508 SIL-3 or ISO 26262 requirements. The Hercules TMS470M family cost efficiently meets the needs of applications that require less
performance and lower safety levels.
The RM48x and TMS570 dual-CPU lockstep architectures simplify development while eliminating redundant system requirements to reduce cost. CPU hardware built-in self test (BIST) detects latent defects without complex safety
software and code-size overhead. Hardware comparison of CPU outputs provides nearly instant safety response time without any additional performance impact. ECC logic is integrated in the CPU to protect both memories
and busses. All RAM memories can be tested using hardware BIST for high diagnostic coverage and an integrated Memory Protection Unit (MPU) helps protect against deterministic errors in application software.
