Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive safety microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F7016453AFP-C#AA1 | Same package and pinout; reduced flash (2 MB) and RAM (256 KB); no Ethernet AVB interface | Suitable for cost-sensitive chassis modules where Ethernet connectivity is not required | Select when ASIL-D compliance and dual-core lockstep are needed but Ethernet AVB and full 4 MB flash are unnecessary |
| TC397XP-128F300S-DC | Infineon AURIX™ TriCore™; 300 MHz tri-core, 4 MB flash, but lacks native 100BASE-T1 Ethernet and uses different safety architecture (HSM vs SCU) | Used in high-performance powertrain ECU designs requiring higher compute throughput than RH850G3K-H offers | Choose when higher single-thread performance and TriCore-specific toolchain integration outweigh RH850's Ethernet AVB advantage |
Compared with R7F7016463AFP-C#AA1, the R7F7016453AFP-C#AA1 reduces memory and removes Ethernet AVB while retaining identical safety architecture and pin compatibility-ideal for scaled-down chassis nodes. The TC397XP offers higher clock speed but requires redesign for Ethernet interface and safety diagnostics due to architectural divergence.

The R7F7016463AFP-C#AA1 integrates 12 CAN FD controllers (up to 5 Mbps), 4 LINFlexD modules, 1 IEEE 802.3bw-compliant 100BASE-T1 Ethernet AVB interface, and 2 FlexRay v2.1A controllers. All interfaces support time-triggered operation, hardware timestamping, and end-to-end protection (CRC, parity, memory ECC). The R7F7016463AFP-C#AA1 does not include USB, SPI flash controllers, or PCIe interfaces.
Is the R7F7016463AFP-C#AA1 pin-compatible with other RH850/F1KH devices?
The R7F7016463AFP-C#AA1 uses the FP-516-2 package and shares pin assignments with other RH850/F1KH-D8 variants such as R7F7016453AFP-C#AA1 and R7F7016473AFP-C#AA1. Pin compatibility is confirmed in Section 2A.1 (Pin Connection Diagram) and Section 2A.2 (Pin Description) of the RH850/F1KH User's Manual: Hardware Rev.1.30. However, functional differences (e.g., Ethernet presence, flash size) require corresponding software and layout validation even when pins match.
What is the qualified temperature grade for the R7F7016463AFP-C#AA1?
The R7F7016463AFP-C#AA1 is qualified per AEC-Q100 Grade 1, supporting operation from −40°C to +125°C ambient temperature.
