Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive safety microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F7017624AFP-C#BA1 | Same package and pinout; increases flash to 6 MB and adds one additional CAN FD channel | Better suited for future-proofed ECU designs requiring larger firmware image size and expanded network connectivity | Select when >4 MB flash or 7th CAN FD channel is required; otherwise R7F7017623AFP-C#BA1 offers optimal cost/performance balance |
| TC397XP-160F300S-DC | Infineon AURIX™ TriCore™; 300 MHz, 8 MB flash, 12 MB RAM; different architecture and toolchain | Targeted at higher-compute ADAS and zonal controller use cases requiring more parallel processing capacity | Choose only if migrating to TriCore ecosystem; not pin-compatible and requires full software re-architecture |
Compared with R7F7017624AFP-C#BA1, the R7F7017623AFP-C#BA1 provides identical safety architecture and peripheral set at lower flash capacity - ideal for cost-sensitive ASIL-D applications. Against TC397XP, it offers Renesas-specific tooling, lower power consumption, and tighter integration with RH850 automotive software stacks, but less raw compute headroom.
