Overview
R7F7016874AFP-C#BA1 from Renesas Electronics is a 32-bit automotive-grade RH850/F1KH-D8 microcontroller featuring dual-core lockstep CPU architecture, 4 MB on-chip flash memory, and integrated ASIL-B compliant safety mechanisms including ECC for RAM/flash, BIST, and windowed watchdog timers. It operates at up to 160 MHz, supports CAN FD (up to 5 channels), and targets engine control units (ECUs) requiring functional safety compliance.
For engineers reviewing the R7F7016874AFP-C#BA1 datasheet, R7F7016874AFP-C#BA1 pinout, R7F7016874AFP-C#BA1 application, or R7F7016874AFP-C#BA1 equivalent, key selection criteria include ASIL-B hardware safety certification, dual-core lockstep execution integrity, flash ECC coverage, CAN FD interface count, and AEC-Q100 Grade 1 qualification for under-hood operation.
Technical Context
The R7F7016874AFP-C#BA1 implements a dual-core RH850 G3KH CPU in lockstep mode with cycle-by-cycle comparison and error detection, enabling real-time fault containment per ISO 26262 requirements. It integrates a dedicated Safety Support Core (SSC) for independent monitoring of CPU execution, memory integrity, and peripheral health.
Hardware safety features include full-flash ECC with single-bit correction/double-bit detection, SRAM ECC with scrubbing, memory BIST for startup and periodic testing, and redundant clock domain monitoring. The device supports configurable partitioning of memory and peripherals between cores for ASIL-B decomposition.
