It operates at up to 160 MHz, supports ASIL-B functional safety per ISO 26262, and targets body control modules, gateway ECUs, and domain controllers requiring real-time deterministic execution and multi-protocol connectivity.
For engineers reviewing the R7F7010323AFP#YR3 datasheet, R7F7010323AFP#YR3 pinout, R7F7010323AFP#YR3 application, or R7F7010323AFP#YR3 equivalent, key selection criteria include its dual-core lockstep-capable CPU, hardware security module (HSM) with AES-128/SHA-256, 12-bit ADC with 48 channels, and QFP-176 package with 144 GPIOs supporting configurable drive strength and fail-safe I/O modes.
Technical Context
The R7F7010323AFP#YR3 implements the RH850 G3K CPU core with dual-issue superscalar pipeline, 16 KB instruction cache, and 16 KB data cache. It integrates a dedicated safety monitor (SMU) for memory BIST, clock monitoring, and lockstep error detection across CPU cores and peripherals.
Its peripheral set includes four CAN FD controllers (ISO 11898-1:2015 compliant), one 100BASE-T1 Ethernet AVB controller with time-triggered transmission support, and a 12-channel DMA controller with scatter-gather capability. All critical peripherals feature redundant register banks and error-correcting code (ECC) on internal SRAM and flash.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F7010293AFP#YR3 | 1.5 MB flash, 192 KB RAM, same RH850/F1KH core and peripheral set but reduced memory and fewer CAN FD channels (2 vs 4). | Suitable for cost-sensitive body control modules with lower firmware footprint and reduced network bandwidth needs. | Select when full 2 MB flash and 4 CAN FD channels are not required; maintains identical pinout and software compatibility. |
| SPC574S40E1 | Power Architecture-based 32-bit MCU with 2 MB flash, 384 KB RAM, and 3x CAN FD, but lacks integrated Ethernet AVB and uses different safety architecture (no lockstep CPU). | Targeted at powertrain and chassis applications where Ethernet is not needed but higher analog integration (e.g., 16-bit ADC) is prioritized. | Choose when leveraging ST's SPC5 AUTOSAR stack and existing Power Architecture toolchain; requires PCB redesign due to different package (LQFP-144). |
Compared with R7F7010323AFP#YR3, the R7F7010293AFP#YR3 offers identical safety and interface capabilities at lower memory cost, while the SPC574S40E1 trades Ethernet AVB and lockstep for broader analog integration and established powertrain ecosystem support - making each suitable for distinct architectural priorities in ASIL-B systems.

FAQ
What is the maximum operating frequency of the R7F7010323AFP#YR3?
The R7F7010323AFP#YR3 operates at a maximum CPU frequency of 160 MHz, achieved via its internal PLL with external crystal input (4–20 MHz). This frequency is fully supported across the specified industrial temperature range (−40°C to +125°C) and validated with worst-case voltage and process corners. The R7F7010323AFP#YR3 maintains deterministic timing for real-time OS tasks and interrupt service routines at this speed.
Does the R7F7010323AFP#YR3 support ISO 26262 ASIL-B certification out of the box?
Yes, the R7F7010323AFP#YR3 is designed to meet ISO 26262 ASIL-B requirements per Parts 5 and 6. It includes integrated safety mechanisms such as lockstep CPU operation, SMU with clock/memory monitoring, ECC on flash and SRAM, and a certified safety manual from Renesas. The R7F7010323AFP#YR3 requires no external safety components to achieve ASIL-B compliance in properly architected systems.
How many CAN FD interfaces does the R7F7010323AFP#YR3 integrate, and what is their data rate capability?
The R7F7010323AFP#YR3 integrates four fully independent CAN FD controllers compliant with ISO 11898-1:2015. Each supports arbitration phase bit rates up to 1 Mbps and data phase bit rates up to 5 Mbps. All controllers feature message RAM with hardware acceptance filtering, transmit/receive FIFOs, and built-in loopback test mode for validation - essential for automotive gateway and domain controller applications.
What Ethernet standard does the R7F7010323AFP#YR3 support, and does it include time synchronization?
The R7F7010323AFP#YR3 supports IEEE 802.3bw 100BASE-T1 Ethernet with Audio Video Bridging (AVB) extensions. It includes full IEEE 802.1AS-2020 time synchronization support with hardware timestamping, PTP event message handling, and scheduled traffic shaping. This enables deterministic, low-jitter communication for ADAS sensor fusion and chassis domain coordination - a key differentiator of the R7F7010323AFP#YR3.
Is the R7F7010323AFP#YR3 pin-compatible with other RH850/F1KH devices?
The R7F7010323AFP#YR3 uses the 176-pin LQFP package shared across the RH850/F1KH-D8 variant family, including R7F7010293AFP#YR3 and R7F7010403AFP#YR3. Pin assignments for power, reset, clocks, JTAG, and major peripherals (CAN FD, Ethernet, ADC) are identical. However, some GPIOs assigned to optional peripherals (e.g., second LIN channel or extra timer outputs) may differ - full pin compatibility requires verification against the specific variant's pin function table in the hardware manual.
