Lifecycle

Status active and in production based on current market data

Not nearing discontinuation as of the latest information

Pin-to-pin equivalents and close variants exist within the RL78 G14 family with different memory sizes and temperature grades verify details and pinouts on the datasheet and ordering guide

Functional alternatives for similar applications include TI MSP430FR series 16-bit low power MCUs and Microchip PIC24FJ series 16-bit MCUs note these are not pin compatible and require redesign
