Product details
Overview
R7F7010423AFP#KA2 from Renesas Electronics is a 32-bit RH850/F1KH-D8 automotive microcontroller featuring a dual-core lockstep CPU, 2 MB on-chip flash memory, 256 KB RAM, and integrated ASIL-B compliant safety mechanisms including ECC for memory, BIST for CPU, and windowed watchdog timers. It supports CAN FD, LIN, and SENT interfaces and is qualified for engine control unit (ECU) applications requiring functional safety up to ISO 26262 ASIL D decomposition.
For engineers reviewing the R7F7010423AFP#KA2 datasheet, R7F7010423AFP#KA2 pinout, R7F7010423AFP#KA2 application, or R7F7010423AFP#KA2 equivalent, key selection criteria include dual-core lockstep execution integrity, ASIL-D decomposable safety architecture, flash ECC coverage, real-time interrupt latency under 50 ns, and automotive-grade AEC-Q100 Grade 1 qualification at −40°C to +125°C junction temperature.
Technical Context
The R7F7010423AFP#KA2 implements two tightly coupled RH850G3K-H cores operating in lockstep mode with cycle-by-cycle comparison and error detection logic. It integrates a dedicated Safety Support Core (SSC) that monitors CPU execution, memory access, and peripheral operation via hardware-assisted safety channels.
Its memory subsystem includes 2 MB of embedded flash with 64-bit ECC protection, 256 KB of SRAM with SEC-DED ECC, and 64 KB of TCM (Tightly Coupled Memory) for deterministic real-time code execution. Peripheral safety features include redundant ADCs with cross-checking, dual-channel PWM with phase-shifted outputs, and configurable windowed watchdog timers with independent clock sources.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive safety microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F7010423AFP#AA1 | Same die, identical core/peripheral set, but rated for AEC-Q100 Grade 2 (−40°C to +105°C) and lacks extended diagnostic coverage for ASIL D decomposition. | Targeted at non-under-hood modules such as HVAC or seat control where ambient temperature stays below 105°C. | Select only when full ASIL-D decomposition and 125°C operation are not required; reduces thermal derating margin and safety analysis scope. |
| SPC574SADK1AKLQ1 | STMicroelectronics SPC574S series; single-core Power Architecture e200z4, 2 MB flash, ASIL D capable but no lockstep CPU - relies on software diversity and BIST. | Used in mid-tier powertrain applications where cost sensitivity outweighs need for hardware lockstep determinism. | Choose when legacy Power Architecture toolchain compatibility is mandatory or when lower interrupt latency tolerance allows software-based safety redundancy. |
Compared with R7F7010423AFP#KA2, the R7F7010423AFP#AA1 offers identical functionality at reduced temperature grade and safety certification scope, while the SPC574SADK1AKLQ1 provides ASIL-D capability through architectural divergence rather than hardware lockstep - resulting in higher software validation burden and longer certification timelines.

FAQ
What is the maximum junction temperature specification for R7F7010423AFP#KA2?
The R7F7010423AFP#KA2 is qualified to AEC-Q100 Grade 1 with a maximum junction temperature of +125°C. This rating is validated across its full operating voltage range (VCC_CORE = 1.14 V to 1.26 V, VCC_IO = 3.135 V to 3.465 V) and ensures reliable operation in under-hood automotive environments such as engine control units. Thermal design must maintain junction temperature within this limit using appropriate PCB copper area and heatsinking.
Does R7F7010423AFP#KA2 support ISO 26262 ASIL D compliance out of the box?
The R7F7010423AFP#KA2 implements an ASIL-D decomposable architecture - including dual-core lockstep, Safety Support Core (SSC), ECC-protected memory, and windowed watchdogs - but full ASIL-D system-level compliance requires proper configuration, safety software integration, and FMEDA analysis per ISO 26262 Part 5. The R7F7010423AFP#KA2 itself provides the hardware foundation and safety mechanisms needed to achieve ASIL-D in certified automotive systems.
What communication interfaces are integrated into R7F7010423AFP#KA2?
The R7F7010423AFP#KA2 integrates four CAN FD controllers compliant with ISO 11898-1:2015, two LIN 2.2a controllers, four SENT receivers for analog sensor interfacing, and one FlexRay v2.1A controller. All interfaces support concurrent operation and feature built-in CRC, filtering, and wakeup capabilities - essential for domain controller architectures in modern vehicles.
How is flash memory protected against corruption in R7F7010423AFP#KA2?
R7F7010423AFP#KA2 flash memory uses full 64-bit ECC protection across its 2 MB array, enabling single-bit error correction and double-bit error detection on every read/write access. It also supports background ECC scrubbing every 100 ms to preemptively correct latent bit flips, and includes write-protection registers and secure boot authentication to prevent unauthorized firmware updates.
Is R7F7010423AFP#KA2 pin-compatible with other RH850/F1KH variants?
No - R7F7010423AFP#KA2 uses a 176-pin LQFP package specific to the RH850/F1KH-D8 variant. While other F1KH devices share the same core architecture, pin assignments differ significantly across sub-families (e.g., F1KH-D4 vs. D8) due to varying peripheral sets and safety module configurations. Direct PCB replacement is not supported; migration requires full schematic and layout review.
