Overview
R7F7010574AFP-C#KA4 from Renesas Electronics is a 32-bit automotive-grade MCU in the RH850/F1KH-D8 family, featuring a dual-core lockstep CPU (G3KH), 1.5 MB on-chip flash, 192 KB RAM, and integrated CAN FD, LIN, and SENT interfaces. It operates at up to 120 MHz, supports ASIL-B functional safety per ISO 26262, and targets engine control units and transmission control modules.
For engineers reviewing the R7F7010574AFP-C#KA4 datasheet, R7F7010574AFP-C#KA4 pinout, R7F7010574AFP-C#KA4 application, or R7F7010574AFP-C#KA4 equivalent, key selection considerations include its dual-core lockstep architecture, ASIL-B certification, 120 MHz real-time performance, integrated hardware security module (HSM), and AEC-Q100 Grade 1 qualification for under-hood operation.
Technical Context
The R7F7010574AFP-C#KA4 implements a dual-core G3KH CPU with hardware lockstep monitoring, enabling real-time fault detection and diagnostic coverage exceeding 90% for ASIL-B compliance. It integrates a 12-bit ADC with 32 channels, 4x 32-bit general-purpose timers, and a dedicated SENT interface supporting both transmitter and receiver modes.
Its peripheral set includes two CAN FD controllers (ISO 11898-1:2015 compliant), three LIN controllers, and an intelligent cryptographic unit (ICUMD) supporting AES-128/256, SHA-256, and RSA-2048. Memory protection is enforced via MPU with 16 regions and ECC on both flash and SRAM.
