Product details
Overview
R7F7010283AFP-C#AA4 from Renesas Electronics is a 32-bit RH850/F1KH-D8 automotive microcontroller featuring dual-core lockstep CPU, 2 MB flash memory, and ASIL-B functional safety compliance for powertrain and chassis control applications.
For engineers reviewing the R7F7010283AFP-C#AA4 datasheet, R7F7010283AFP-C#AA4 pinout, R7F7010283AFP-C#AA4 application, or R7F7010283AFP-C#AA4 equivalent, key selection considerations include dual-core lockstep execution, integrated CAN FD and LIN interfaces, 12-bit ADC with 48 channels, hardware-based safety mechanisms (ECC, BIST, watchdog), and AEC-Q100 Grade 1 qualification.
Technical Context
This MCU implements a dual-core RH850 G3KH CPU in lockstep mode with hardware comparison logic to detect transient faults, supporting ISO 26262 ASIL-B system-level compliance. It integrates a 12-channel DMA controller, 48-channel 12-bit SAR ADC with scan sequencing, and 8-channel PWM with dead-time insertion.
The device includes three CAN FD controllers (ISO 11898-1:2015 compliant), two LIN bus controllers, and a 16-channel SENT interface for sensor communication. Memory protection units (MPUs) and error-correcting code (ECC) on both flash and SRAM enforce runtime integrity.
