Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F123G | Same RL78/F23 family, 44-pin QFP, 20x 12-bit ADC, 48 KB Flash - higher I/O count but larger footprint | Preferred for designs requiring >32 GPIOs or additional UART/LIN channels | Select R7F123G only if board layout allows QFP package and extra ADC channels are needed for multi-sensor fusion |
| R7F124B | RL78/F24 family, 32-pin QFN, 256 KB Flash, 16 KB RAM, CAN FD support - higher memory and communication capability | Required where CAN FD backbone integration or future firmware expansion beyond 128 KB is mandated | Choose R7F124B when CAN FD interoperability or >2× Flash headroom for secure boot/AES crypto stacks is required |
Compared with R7F702300BEBBB-C#BC6, R7F123G offers more I/O and ADC resources in QFP form but lacks 150°C rating; R7F124B adds CAN FD and doubles Flash but increases cost and power - making R7F702300BEBBB-C#BC6 optimal for cost-sensitive, thermally demanding LIN-only nodes.
