Product details
Overview
R7F7010423AFP#AA2 from Renesas Electronics is a 32-bit RH850/F1KH-D8 automotive microcontroller featuring a 200 MHz core clock, 2 MB flash memory, and integrated CAN FD, LIN, and SENT interfaces. It implements dual-lockstep CPU cores for ASIL-D functional safety compliance and includes hardware security modules (ICUMD) for cryptographic acceleration. It is deployed in engine control units (ECUs) requiring real-time deterministic execution and ISO 26262 certification support.
For engineers reviewing the R7F7010423AFP#AA2 datasheet, R7F7010423AFP#AA2 pinout, R7F7010423AFP#AA2 application, or R7F7010423AFP#AA2 equivalent, key selection criteria include ASIL-D safety architecture validation, flash endurance (100k write/erase cycles), CAN FD data rate (up to 5 Mbps), on-chip voltage regulator tolerance (±3%), and qualification per AEC-Q100 Grade 1 (-40°C to +125°C).
Technical Context
The R7F7010423AFP#AA2 integrates a dual-core RH850 G3KH CPU with lockstep monitoring, supporting time-triggered execution and error-correcting code (ECC) on both instruction and data SRAM. Its peripheral set includes 4x CAN FD controllers with protocol offload, 2x SENT receivers for sensor interface, and a 12-bit ADC with 16-channel simultaneous sampling.
Hardware safety features include BIST (Built-In Self-Test) for CPU and memory, FMEDA-verified diagnostic coverage >90% for ASIL-D, and redundant clock monitoring with fail-safe interrupt generation. The device uses a 176-pin LQFP package with dedicated safety pins (e.g., ERRN, SAFETY_RST) routed separately from functional I/O.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive safety microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F7010223AFP#AA2 | 1 MB flash, no ICUMD, 2 CAN FD channels - lacks hardware crypto and half the flash capacity. | Suitable for non-secure body control modules where OTA encryption is not required. | Select when cost-sensitive Tier-2 body electronics require ASIL-B compliance without secure boot. |
| SPC58EC80E5 | Power Architecture e200z7, 4 MB flash, 3 CAN FD, no SENT receivers - different ISA and missing sensor interface. | Used in chassis domain controllers where legacy PowerPC toolchains are mandated. | Choose only if existing SPC5 ecosystem and AUTOSAR Classic stack compatibility outweigh RH850 toolchain advantages. |
Compared with R7F7010423AFP#AA2, the R7F7010223AFP#AA2 reduces flash and security capability for cost-constrained ASIL-B use cases, while the SPC58EC80E5 offers higher flash but requires architectural revalidation and lacks native SENT support critical for modern powertrain sensing.

FAQ
What is the maximum operating frequency of the R7F7010423AFP#AA2?
The R7F7010423AFP#AA2 operates at a maximum core clock frequency of 200 MHz. This speed is sustained across its full AEC-Q100 Grade 1 temperature range (−40°C to +125°C) with on-chip voltage regulation and thermal monitoring. The R7F7010423AFP#AA2 achieves this performance using the RH850 G3KH dual-core architecture with optimized pipeline depth and branch prediction, enabling deterministic real-time response in safety-critical automotive applications.
Does the R7F7010423AFP#AA2 support CAN FD, and what data rates does it achieve?
Yes, the R7F7010423AFP#AA2 integrates four fully independent CAN FD controllers compliant with ISO 11898-1:2015. Each channel supports arbitration bit rates up to 1 Mbps and data phase bit rates up to 5 Mbps. The R7F7010423AFP#AA2 implements hardware-based bit-rate switching, CRC offload, and configurable TX/RX FIFOs-reducing CPU load during high-throughput diagnostics and actuator telemetry. These capabilities are validated in Renesas' RH850/F1KH hardware user manual Rev.1.30.
What safety certifications apply to the R7F7010423AFP#AA2?
The R7F7010423AFP#AA2 is designed to support ASIL-D compliance per ISO 26262:2018, with FMEDA documentation, dual-lockstep CPU, ECC-protected memories, BIST, and dedicated safety pins (ERRN, SAFETY_RST). It is qualified to AEC-Q100 Grade 1 (−40°C to +125°C) and includes hardware safety mechanisms verified by third-party labs. The R7F7010423AFP#AA2 itself is not "certified" as a standalone item-the final system certification depends on correct implementation per Renesas' safety manual and customer-specific safety case development.
How many SENT receiver channels does the R7F7010423AFP#AA2 provide?
The R7F7010423AFP#AA2 includes four dedicated SENT receiver channels (SENT0 through SENT3), each capable of decoding standard 3–5 V unidirectional pulse-width modulated signals from pressure, temperature, and position sensors. Each channel supports programmable pulse width resolution down to 55 µs and automatic frame synchronization-enabling direct interface to automotive sensors without external signal conditioning. This SENT capability is documented in Section 1A.2 of the RH850/F1KH hardware user manual.
What is the flash memory endurance specification for the R7F7010423AFP#AA2?
The R7F7010423AFP#AA2 specifies 100,000 write/erase cycles for its 2 MB on-chip flash memory, with data retention guaranteed for 20 years at 125°C. Flash operations include ECC protection, wear leveling support in firmware, and secure erase functionality. This endurance rating meets the requirements for frequent over-the-air (OTA) firmware updates in modern ECU architectures. The R7F7010423AFP#AA2 flash endurance is defined in Renesas' RH850/F1KH flash memory user's manual R01UH0622EJxxxx.
