Lifecycle

Current status Generally active within the RH850/C1M-Ax family for automotive use

Nearing discontinuation No indication of end of life for this variant based on current information

Pin-compatible or close family alternatives Within the same RH850/C1M-Ax family, options may include R7F701275EAFP, R7F701276EAFP, R7F701277EAFP, and other R7F70127x variants. These differ by memory size, peripheral mix, and sometimes I/O count. Check exact pinout and features in the datasheets

Functionally similar alternatives If you need similar performance and automotive networking but do not require pin compatibility, consider other RH850 families such as RH850/F1x or RH850/E2x depending on peripheral needs and safety requirements. Verify details in their datasheets
