It supports CAN FD (up to 5 channels), LIN, SENT, and Ethernet AVB interfaces, and is qualified for automotive powertrain and chassis control applications.
For engineers reviewing the R7F7015873AFP-C#AA3 datasheet, R7F7015873AFP-C#AA3 pinout, R7F7015873AFP-C#AA3 application, or R7F7015873AFP-C#AA3 equivalent, key selection considerations include ASIL-D compliance, dual-core lockstep execution integrity, Flash ECC coverage, real-time interrupt latency under 50 ns, and support for ISO 26262 FMEDA documentation.
Technical Context
The R7F7015873AFP-C#AA3 implements a dual-core RH850 G3KH CPU in lockstep mode with hardware-based comparison logic that triggers immediate error signaling upon mismatch. Its memory subsystem includes 3MB of Flash with 100% ECC coverage, 384KB of SRAM with full ECC, and 64KB of TCM for deterministic real-time code execution.
Peripheral integration includes five CAN FD controllers (ISO 11898-1:2015 compliant), four 12-bit ADCs with 48-channel multiplexing, SENT receivers for sensor interface, and an Ethernet AVB controller supporting IEEE 802.1AS time synchronization - all accessible via dedicated DMA channels with configurable priority arbitration.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive safety microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F7015833AFP-C#AA3 | Same RH850/F1K family, reduced Flash (2MB) and RAM (256KB); identical pinout and peripheral set | Suitable for cost-sensitive ASIL-B/C applications where full 3MB firmware footprint is not required | Select when BOM cost reduction is prioritized over future firmware scalability and diagnostic memory headroom |
| TC377TP-64F200N-DC | Infineon AURIX TC3xx tri-core architecture; no lockstep CPU pairs but uses split-lock and shadow core for safety | Requires different safety software architecture and lacks native SENT receiver hardware blocks | Choose when existing AURIX toolchain investment exists or when higher floating-point throughput is needed over lockstep determinism |
Compared with R7F7015873AFP-C#AA3, the R7F7015833AFP-C#AA3 offers identical safety architecture and pin compatibility at lower memory capacity, while the TC377TP trades lockstep CPU assurance for tri-core flexibility and higher DSP performance - making R7F7015873AFP-C#AA3 optimal for strict ASIL-D time-deterministic control where hardware-level fault detection is non-negotiable.
