It operates at up to 120 MHz, supports ASIL-B functional safety per ISO 26262, and targets body control modules and gateway ECUs requiring real-time deterministic execution and secure communication.
For engineers reviewing the R7F7010303AFP-C#AA4 datasheet, R7F7010303AFP-C#AA4 pinout, R7F7010303AFP-C#AA4 application, or R7F7010303AFP-C#AA4 equivalent, key selection criteria include ASIL-B compliance, dual-core lockstep support, Flash ECC protection, and automotive-grade temperature range (–40°C to +125°C) for under-hood deployment.
Technical Context
The R7F7010303AFP-C#AA4 implements a dual-core RH850 G3KH CPU architecture with lockstep operation for fault detection, coupled with a dedicated Safety Support Core (SSC) for runtime diagnostics. It integrates a 12-bit ADC with 48 channels, 32-bit timer units (GPTA/GPTB), and a hardware security module supporting AES-128, SHA-256, and TRNG.
Its peripheral set includes two CAN FD controllers (ISO 11898-1:2015 compliant), one 100BASE-T1 Ethernet AVB interface with time-sensitive networking (TSN) support, and four LIN transceivers. Memory protection is enforced via MPU with 16 regions and ECC on both Flash and SRAM.
