Product details
Overview
R7F7010493AFP#AA4 from Renesas Electronics is a 32-bit automotive-grade MCU in the RH850/F1KH-D8 family, featuring a dual-core lockstep CPU architecture, 1.25 MB on-chip flash memory, and integrated safety mechanisms including ECC for flash and RAM, BIST, and hardware watchdog timers. 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 R7F7010493AFP#AA4 datasheet, R7F7010493AFP#AA4 pinout, R7F7010493AFP#AA4 application, or R7F7010493AFP#AA4 equivalent, key selection considerations include its dual-core lockstep execution, ASIL-B ready safety features, 120 MHz real-time performance, and support for CAN FD, LIN, and SENT interfaces in automotive powertrain systems.
Technical Context
The R7F7010493AFP#AA4 implements two synchronized RH850 G3KH CPU cores executing identical instruction streams with cycle-by-cycle comparison to detect transient faults. Its safety subsystem includes dedicated error detection logic for bus interconnects, memory controllers, and peripheral bridges - all monitored by an independent Safety Management Unit (SMU).
It integrates 128 KB of SRAM with ECC protection, 1.25 MB flash with read-while-write capability and background CRC checking, and a full suite of automotive peripherals: 4x CAN FD controllers (with time-triggered communication support), 6x SENT receivers, 4x LINFlexD modules, and 24-channel ePWM with dead-time insertion and fault protection.

Pin functions are identical across these parts for power, reset, clocks, and core peripherals. However, some alternate function mappings (e.g., SENT channel assignment or ADC input routing) differ between variants - so PCB layout reuse requires verification against the specific variant's pin description table in the R01UH0622EJ hardware manual for R7F7010493AFP#AA4.
