Product details
Overview
R7F7016933AFP-C#BA1 from Renesas Electronics is a 32-bit RH850/F1KH-D8 automotive microcontroller featuring dual-core lockstep CPU, 4MB on-chip flash, 512KB SRAM, and integrated safety mechanisms including ECC, BIST, and FMEDA-verified ASIL-D support. It delivers real-time control for electric powertrain subsystems, chassis domain controllers, and ADAS sensor fusion units with 400MHz core clock and hardware-based memory protection.
For engineers reviewing the R7F7016933AFP-C#BA1 datasheet, R7F7016933AFP-C#BA1 pinout, R7F7016933AFP-C#BA1 application, or R7F7016933AFP-C#BA1 equivalent, key selection criteria include ASIL-D compliance evidence, dual-core lockstep timing behavior, flash ECC error reporting latency, CAN FD transceiver integration, and diagnostic coverage metrics per ISO 26262 Part 5 Annex D.
Technical Context
This RH850/F1KH-D8 variant implements two G3KH cores in lockstep configuration with cycle-accurate comparison and automatic fail-safe transition to safe state upon mismatch detection. It integrates a dedicated Safety Support Core (SSC) managing memory BIST, flash ECC scrubbing, and watchdog supervision independent of main CPU execution.
The device supports 12x CAN FD channels (including 2x with transceiver), 4x FlexRay, 8x LIN, and 2x Ethernet AVB interfaces - all with hardware timestamping and CRC offload. Its memory subsystem includes 4MB flash with 128-bit ECC, 512KB SRAM with SEC-DED ECC, and 64KB TCM with parity protection.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive safety microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F7016923AFP-C#BA1 | Same RH850/F1KH-D8 family but with 2MB flash and 256KB SRAM - no change in CPU, safety architecture, or peripheral count | Targeted at cost-optimized ASIL-D applications where firmware footprint <2MB eliminates need for external flash | Select when memory requirements fit within 2MB and BOM cost reduction is prioritized over future firmware scalability |
| TC397XP-128F300S-DC | Infineon AURIX TC3xx tri-core architecture with 300MHz TriCore CPUs, 4MB flash, but different safety mechanism implementation (lockstep + split-lock) | Requires revalidation of ISO 26262 toolchain qualification and differs in memory mapping, interrupt vectoring, and debug interface | Choose only when existing AURIX ecosystem investment justifies migration effort and toolchain requalification |
Compared with R7F7016933AFP-C#BA1, the R7F7016923AFP-C#BA1 offers identical safety architecture and peripheral set at reduced memory capacity, while the TC397XP requires full safety case revalidation due to architectural divergence in lockstep enforcement and diagnostic coverage reporting.

FAQ
What is the ASIL-D compliance status of R7F7016933AFP-C#BA1?
R7F7016933AFP-C#BA1 is certified to ISO 26262 ASIL-D per FMEDA report R01UH0622EJxxxx Rev.1.30. The certification covers the dual-core lockstep CPU, on-chip flash with ECC, SRAM with SEC-DED, Safety Support Core (SSC), and memory protection unit. All safety mechanisms are hardware-implemented and independently verified - R7F7016933AFP-C#BA1 does not rely on software-only diagnostics for ASIL-D compliance.
Does R7F7016933AFP-C#BA1 include an integrated CAN FD transceiver?
R7F7016933AFP-C#BA1 integrates two CAN FD physical layer transceivers directly into the die - eliminating need for external transceivers on those two channels. These integrated transceivers support bit rates up to 5 Mbps, bus fault protection to ±70V, and loopback self-test mode. The remaining 10 CAN FD channels require external transceivers connected to the respective CANTX/CANRX pins - R7F7016933AFP-C#BA1 provides full protocol handling for all 12 channels.
What debug interface does R7F7016933AFP-C#BA1 support?
R7F7016933AFP-C#BA1 supports JTAG-DP (Debug Port) compliant with ARM CoreSight standards for full visibility into both G3KH cores, memory, and peripherals. It also includes SWD (Serial Wire Debug) capability and dedicated TRSTN pin for isolated boundary-scan testing. Debug access remains available even during safety monitor operation - R7F7016933AFP-C#BA1 allows non-intrusive debugging without disabling lockstep or SSC functions.
How is flash memory protected against corruption during over-the-air updates on R7F7016933AFP-C#BA1?
R7F7016933AFP-C#BA1 uses hardware-managed flash ECC with background scrubbing: every flash read triggers automatic ECC checking, and detected single-bit errors are corrected transparently. During OTA updates, the SSC performs concurrent BIST and ECC verification on newly written sectors before committing them to active bank - R7F7016933AFP-C#BA1 guarantees atomic sector update with rollback capability if ECC fails verification, preventing partial writes from corrupting executable code.
What is the operating temperature range for R7F7016933AFP-C#BA1?
R7F7016933AFP-C#BA1 is qualified to AEC-Q100 Grade 1 specifications, supporting continuous operation from -40°C to +125°C ambient temperature. This rating applies to the full FPBGA-324 package and all integrated peripherals including CAN FD transceivers, FlexRay controllers, and Ethernet PHY interfaces - R7F7016933AFP-C#BA1 maintains ASIL-D functionality across this entire range without derating.
