Overview

The TMS5701227CPGEQQ1 is a high-performance, automotive-grade microcontroller based on the ARM Cortex-R4F dual-core architecture. Part of the Hercules family, it is specifically engineered for ISO 26262 ASIL D and IEC 61508 SIL 3 functional safety applications by utilizing hardware-based safety features. It operates at up to 160MHz and includes 1.25MB of Flash with ECC protection and 192KB of RAM.

Why Choose This Part

The primary advantage is the hardware-integrated safety logic, including dual CPUs in lockstep and Built-In Self-Test (BIST) for both CPU and RAM. It simplifies certification by providing comprehensive diagnostic coverage and ECC on all on-chip memories, significantly reducing the software overhead typically required for functional safety.

Applications

Electronic Power Steering (EPS)
Utilizes the dual-core lockstep architecture to ensure safety-critical motor control logic is executed correctly.
Anti-Lock Braking Systems (ABS)
Leverages integrated CANbus and FlexRay interfaces for high-speed, reliable vehicle networking in braking modules.
Industrial Safety Controllers
Provides hardware-level BIST and ECC for memory to meet stringent IEC 61508 SIL 3 reliability requirements.
Advanced Driver Assistance Systems (ADAS)
Acts as a safety co-processor to monitor system health and manage fail-safe states in autonomous driving platforms.
