Overview
R7F7010173AFP#KA4 from Renesas Electronics is a 32-bit RH850/F1KH-D8 automotive microcontroller featuring a dual-core lockstep CPU, 1.5 MB on-chip flash memory, and integrated safety mechanisms including ECC for flash and RAM, BIST, and FMEDA-compliant diagnostics. It operates at up to 120 MHz, supports ASIL-B compliance per ISO 26262, and targets engine control units (ECUs) requiring functional safety.
For engineers reviewing the R7F7010173AFP#KA4 datasheet, R7F7010173AFP#KA4 pinout, R7F7010173AFP#KA4 application, or R7F7010173AFP#KA4 equivalent, key selection criteria include ASIL-B diagnostic coverage, dual-core lockstep execution integrity, 120 MHz real-time performance, and automotive-grade AEC-Q100 Grade 1 qualification - all confirmed for this specific part number.
Technical Context
The R7F7010173AFP#KA4 implements a dual-core RH850 G3KH CPU in lockstep mode with cycle-by-cycle comparison and error detection logic, enabling safe execution of safety-critical tasks. It integrates a 12-channel eTimer module with PWM generation, 2x CAN FD controllers (ISO 11898-1:2015 compliant), and 16-bit ADC with 24 channels and 1.0 µs conversion time.
Hardware safety features include memory protection unit (MPU), clock fail-safe circuitry with watchdog timer (WDT) and windowed WDT, and dedicated safety monitor (SMU) that validates CPU operation, memory integrity, and peripheral health. All safety mechanisms are documented in the RH850/F1KH User's Manual Rev.1.30 and validated for ASIL-B system integration.
