Product details
Overview
R7F7010323AFP#KA3 from Renesas Electronics is a 32-bit RH850/F1KH-D8 automotive microcontroller featuring a dual-core lockstep CPU, 2 MB flash memory, 256 KB RAM, and integrated CAN FD, LIN, and Ethernet AVB interfaces. It operates at up to 160 MHz, supports ASIL-D functional safety per ISO 26262, and targets engine control units (ECUs) requiring high-integrity real-time processing.
For engineers reviewing the R7F7010323AFP#KA3 datasheet, R7F7010323AFP#KA3 pinout, R7F7010323AFP#KA3 application, or R7F7010323AFP#KA3 equivalent, key selection criteria include dual-core lockstep execution integrity, on-chip flash ECC with error injection test support, hardware-based memory protection unit (MPU), and qualification for automotive AEC-Q100 Grade 1 operation across –40°C to +125°C ambient.
Technical Context
The R7F7010323AFP#KA3 implements two synchronized RH850 G3KH CPU cores executing identical instructions in lockstep, with dedicated comparator logic detecting divergence within one clock cycle. It integrates a 16-channel e200z7-based DMA controller, 48-channel event link controller (ELC), and 32-channel interrupt controller supporting priority nesting and vectoring.
Hardware safety features include dual independent watchdog timers (WDT and SWDT), voltage/frequency monitors, BIST-enabled flash and RAM self-tests, and a dedicated safety management unit (SMU) that logs fault events and triggers safe state transitions. All peripheral modules support register lock protection and parity/ECC on configuration memory.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F7010223AFP#KA3 | 1 MB flash, 128 KB RAM, same package and pinout; lacks Ethernet AVB and one CAN FD channel | Suitable for cost-sensitive ASIL-B/C ECUs where Ethernet connectivity is not required | Select when system requirements exclude Ethernet AVB and total flash usage remains below 1 MB |
| SPC5744PFK1AKLQ1 | Power Architecture e200z4 dual-core, 2 MB flash, 384 KB RAM, supports AUTOSAR 4.3 but no native Ethernet AVB | Targets legacy AUTOSAR toolchains; requires external PHY for 100BASE-T1 implementation | Choose for existing SPC57xx-based platforms needing migration path with minimal software rework |
Compared with R7F7010323AFP#KA3, the R7F7010223AFP#KA3 reduces memory and interface count for lower-cost ASIL-B systems, while the SPC5744PFK1AKLQ1 offers AUTOSAR-native support but requires external Ethernet PHY and lacks integrated AVB MAC-layer acceleration.

FAQ
What is the maximum operating junction temperature for R7F7010323AFP#KA3?
The R7F7010323AFP#KA3 has a maximum junction temperature of +150°C, validated under AEC-Q100 Grade 1 conditions (–40°C to +125°C ambient). Thermal design must maintain junction temperature below this limit using the specified thermal resistance (θJA = 28°C/W for 176-pin LQFP) and appropriate PCB copper area per Renesas Application Note R01AN3819EJ.
Does R7F7010323AFP#KA3 support AUTOSAR 4.x compliant software stacks?
Yes, R7F7010323AFP#KA3 is certified for AUTOSAR 4.3 and later versions. Renesas provides the EB tresos AutoCore RH850 platform package, including MCAL drivers, OS, and COM stack, fully validated for R7F7010323AFP#KA3 with dual-core lockstep and SMU integration.
How is flash memory protected against corruption during power fluctuations on R7F7010323AFP#KA3?
R7F7010323AFP#KA3 uses hardware-implemented flash ECC with SEC-DED capability, coupled with a power-fail detection circuit that triggers automatic flash write abort and recovery sequence. The on-chip voltage monitor asserts PFS (Power Fail Signal) before VDD drops below 2.7 V, enabling safe state entry and flash state rollback.
Can R7F7010323AFP#KA3 operate in single-core mode for non-safety applications?
No - R7F7010323AFP#KA3 requires both cores to operate in lockstep mode per its safety architecture. The hardware does not support independent core execution or disabling of lockstep verification; attempting to do so violates ASIL-D certification and disables critical safety mechanisms.
What debug interface does R7F7010323AFP#KA3 provide for production programming and field diagnostics?
R7F7010323AFP#KA3 supports JTAG-DP (ARM CoreSight-compatible) and Nexus Class 3+ trace interface via pins TDI/TDO/TMS/TCK/TRST/TRACECLK/TRACECTL. Production programming uses Renesas Flash Programmer with E1/E20 emulators, while field diagnostics leverage the built-in ROM bootloader accessible via CAN FD or UART boot modes.
