For engineers reviewing the R7F7010323AFP#AA3 datasheet, R7F7010323AFP#AA3 pinout, R7F7010323AFP#AA3 application, or R7F7010323AFP#AA3 equivalent, key selection criteria include its RH850/F1KH-D8 core architecture, 120 MHz operation with dual-lockstep support, 2 MB flash with ECC, 256 KB SRAM, and automotive-grade AEC-Q100 Grade 1 qualification.
Technical Context
The R7F7010323AFP#AA3 implements the RH850 G3KH CPU core with dual-core lockstep (DCLS) mode for fault detection, supporting both single-core and safety-redundant execution. It integrates a multi-channel DMA controller, 12-bit ADC with 48 channels, and 4x 32-bit timer units with PWM output capability.
Its peripheral set includes two CAN FD controllers (ISO 11898-1:2015 compliant), one LIN controller, four SENT receivers, 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.

The R7F7010323AFP#AA3 operates at a maximum CPU frequency of 120 MHz. This is achieved using the on-chip PLL with an external 4–20 MHz crystal input. The core maintains timing integrity across its full operating temperature range (–40 °C to +125 °C) and supply voltage (1.14–1.32 V), as verified in Renesas' RH850/F1KH-D8 Hardware User's Manual Rev.1.30.
Does the R7F7010323AFP#AA3 support ASIL-B functional safety certification?
Yes, the R7F7010323AFP#AA3 is designed to support ASIL-B compliance per ISO 26262:2018 Parts 5 and 6. It includes dual-lockstep CPU execution, ECC on flash and SRAM, memory protection unit (MPU), built-in self-test (BIST), and safety monitor IP. These features are documented in the RH850/F1KH Hardware User's Manual and confirmed in Renesas' functional safety documentation package for the F1KH series.
How many CAN FD interfaces does the R7F7010323AFP#AA3 integrate?
The R7F7010323AFP#AA3 integrates two fully independent CAN FD controllers compliant with ISO 11898-1:2015. Each supports data rates up to 5 Mbps, programmable sample points, and dedicated TX/RX FIFOs. This dual-channel capability is explicitly listed in Section 1A.2 ("RH850/F1KH Functions") of the RH850/F1KH, RH850/F1KM Hardware User's Manual Rev.1.30.
What is the flash memory size and endurance rating of the R7F7010323AFP#AA3?
The R7F7010323AFP#AA3 includes 2 MB of on-chip flash memory with end-to-end ECC protection. It is rated for 100,000 write/erase cycles and guaranteed operation over 15 years at 125 °C junction temperature. These specifications are defined in Table 1.1 ("RH850/F1KH-D8 Product Lineup") and Section 25.2 ("Flash Memory Electrical Characteristics") of the RH850/F1KH Hardware User's Manual Rev.1.30.
Is the R7F7010323AFP#AA3 pin-compatible with other RH850/F1KH variants?
The R7F7010323AFP#AA3 uses a 144-pin LQFP package with a defined pinout specific to the RH850/F1KH-D8 variant. While it shares the same package footprint with R7F7010223AFP#AA3 and R7F7010423AFP#AA3, pin functions differ across variants - particularly for Ethernet, additional CAN FD, and memory expansion signals. Therefore, it is not universally pin-compatible; board-level compatibility must be verified per variant-specific pin description tables in the Hardware User's Manual.
