Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive safety microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F7016883AFP-C#AA1 | Same RH850/F1KH-D8 family, but with 2 MB flash and no Ethernet AVB MAC - lacks time-synchronized networking capability. | Suitable for cost-optimized powertrain ECUs where Ethernet connectivity is not required. | Select when system-level bandwidth and time-coordination demands are limited to CAN FD only. |
| TC397XP-160F300N-DC | Infineon AURIX™ TC3xx tri-core architecture with 300 MHz TriCore CPUs; 4 MB flash but no native Ethernet AVB - requires external PHY and software stack for time sync. | Used in chassis and safety domain controllers requiring high MIPS but less stringent time-sync precision than AVB. | Choose when existing AURIX toolchain and AUTOSAR stack investment outweighs need for integrated Ethernet hardware timestamping. |
Compared with R7F7017093AFP-C#AA1, the R7F7016883AFP-C#AA1 reduces flash capacity and omits Ethernet AVB, limiting its use in domain controllers; the TC397XP offers higher raw compute throughput but requires external components and software effort to achieve comparable time-synchronization fidelity.
