It operates at up to 160 MHz, supports ASIL-D functional safety per ISO 26262, and targets engine control units (ECUs) requiring high-integrity real-time processing.
For engineers reviewing the R7F7010253AFP-C#AA2 datasheet, R7F7010253AFP-C#AA2 pinout, R7F7010253AFP-C#AA2 application, or R7F7010253AFP-C#AA2 equivalent, key selection criteria include dual-core lockstep verification, on-chip flash ECC with error injection test support, ASIL-D hardware safety mechanisms (e.g., BIST, memory parity, clock monitor), and automotive-grade AEC-Q100 Grade 1 qualification.
Technical Context
The R7F7010253AFP-C#AA2 implements a dual-core RH850G3K-H CPU in lockstep mode with cycle-accurate comparison and automatic fault detection. It integrates a 2-channel CAN FD controller supporting data rates up to 5 Mbps, a 100BASE-T1 Ethernet AVB interface with time-triggered scheduling, and a dedicated Safety Support Core (SSC) for independent monitoring of CPU, memory, and peripheral integrity.
Hardware safety features include a Memory Built-in Self-Test (MBIST) covering all embedded SRAM and flash, a Clock Frequency Monitor (CFM) with windowed watchdog, and a Peripheral Functional Safety Checker (PFSC) that validates register access sequences and peripheral state transitions against predefined safety rules.
