Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive safety microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F7010574AFP#AA0 | Same die and package; differs only in mask revision and factory-programmed boot ROM content | No functional difference; intended for different production lots with updated firmware image | Select #AA0 only when matching specific OEM software version requirements |
| MB9B560RPMC | Fujitsu MB9B560R series; single-core ARM Cortex-R5F, 1.5 MB flash, no lockstep, ASIL-B via software partitioning only | Lacks hardware lockstep and SSU; requires additional safety software layers for ASIL-B compliance | Choose only if legacy toolchain compatibility or lower cost outweighs need for hardware fault detection |
Compared with R7F7010574AFP#AA3, the #AA0 variant offers identical hardware functionality but targets distinct firmware load configurations, while the MB9B560RPMC requires external safety mechanisms to achieve comparable ASIL-B integrity - increasing software validation burden and reducing fault coverage.

The R7F7010574AFP#AA3 is certified to ISO 26262 ASIL-B at the device level, with full documentation of FMEDA, safety mechanisms (lockstep CPU, SSU, ECC, BIST), and diagnostic coverage metrics. It meets AEC-Q100 Grade 1 requirements for automotive operation from –40°C to +125°C. Renesas provides certified safety manuals and hardware abstraction layer (HAL) libraries to support ASIL-B integration in customer systems. The R7F7010574AFP#AA3 includes built-in self-test routines validated per ISO 26262 Annex D.
Does the R7F7010574AFP#AA3 support CAN FD with bit rate switching?
Yes, the R7F7010574AFP#AA3 supports full CAN FD operation including bit rate switching, with five independent CAN FD controllers compliant to ISO 11898-1:2013. Each controller supports arbitration bit rates up to 1 Mbps and data bit rates up to 5 Mbps, with flexible payload lengths (up to 64 bytes) and CRC-17/CRC-21 calculation in hardware. The R7F7010574AFP#AA3 implements dedicated message RAM with configurable TX/RX buffers and hardware timestamping for deterministic network synchronization.
What is the maximum operating frequency of the R7F7010574AFP#AA3 CPU?
The R7F7010574AFP#AA3 operates at a maximum CPU frequency of 120 MHz under nominal voltage and temperature conditions. Its dual RH850 G3KH cores run synchronously in lockstep, with pipeline stalls and branch prediction optimized for deterministic real-time execution. The core clock is derived from an on-chip PLL fed by either an external crystal (4–20 MHz) or oscillator input, with spread-spectrum modulation support to reduce EMI. The R7F7010574AFP#AA3 maintains timing integrity across its full operating range without performance throttling.
How is flash memory protected against corruption in the R7F7010574AFP#AA3?
The R7F7010574AFP#AA3 implements end-to-end flash protection using SEC-DED ECC (single-error correction, double-error detection) across all 2 MB of on-chip flash, with dedicated error correction logic that operates transparently during read/write/erase cycles. Flash access is gated by a hardware firewall with region-based privilege control, and programming is restricted to secure boot ROM or authenticated firmware updates. The R7F7010574AFP#AA3 also includes flash BIST (built-in self-test) for production screening and runtime integrity checks.
Can the R7F7010574AFP#AA3 be used in non-automotive applications?
While the R7F7010574AFP#AA3 is designed and qualified for automotive use (AEC-Q100 Grade 1, ISO 26262 ASIL-B), it may be deployed in industrial or medical applications where high reliability, extended temperature tolerance, and functional safety features are required - provided the end application undergoes full system-level safety assessment. Renesas does not guarantee suitability for life-support or aerospace use without additional qualification. The R7F7010574AFP#AA3's robust I/O drive strength, ESD immunity (±6 kV HBM), and EMC resilience make it viable for harsh-environment industrial controls, though its toolchain and support ecosystem are optimized for automotive development workflows.
