IC Role / Device Role / Timing Role: High-integrity domain manager interfacing with multiple CAN FD networks and Ethernet AVB, using ICUMD for secure OTA update authentication. Use Value: Provides hardware-enforced separation between safety-critical and non-safety partitions, enabling mixed-ASIL software deployment on single die. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive safety microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F7016893AFP-C#KA1 | Same RH850/F1KH-D8 family, but with 2 MB flash, 256 KB SRAM, and no ICUMD cryptographic engine | Lacks hardware crypto acceleration and secure boot - unsuitable for OTA-secured ECUs requiring FIPS-aligned key management | Select when ASIL-B compliance is required but cryptographic functions are implemented externally or omitted |
| TC377TP-128F300SRL | Infineon AURIX™ TC3xx tri-core architecture with lockstep, 4 MB flash, but no integrated Ethernet AVB or ICUMD-equivalent security module | Requires external PHY and separate HSM for secure boot - increases BOM count and layout complexity | Choose if existing design uses AURIX toolchain and ecosystem, or when higher core count (3x TriCore) outweighs RH850's crypto integration |
Compared with R7F7017093AFP-C#KA1, the R7F7016893AFP-C#KA1 reduces memory and omits crypto acceleration for cost-sensitive ASIL-B applications, while the TC377TP offers tri-core flexibility at the expense of integrated security and Ethernet AVB - making R7F7017093AFP-C#KA1 optimal for secure, networked automotive controllers needing minimal external components.
