Lifecycle

Current status generally active in the RL78 G13 family based on our latest review

Not nearing discontinuation to the best of our knowledge

Equivalent or alternative models within the RL78 G13 family may include pin compatible and memory size variants in 64-LQFP such as R5F101Kxxxx approximately 64KB Flash, R5F101Mxxxx approximately 128KB Flash, and higher memory options when available exact ordering codes depend on options like package finish, temperature grade, and shipping form

Higher performance alternative RL78 G14 family for more timers and enhanced features while keeping similar development flow

Cost optimized alternative RL78 G12 family for simpler applications with fewer peripherals
