Key Advantages

Low power RL78 architecture reduces energy use in battery and mains-powered designs

Wide supply range (1.6V–5.5V) simplifies power design and supports 5V systems

Rich integrated peripherals cut BOM and save board space

Internal oscillator and POR/LVD speed up startup and improve robustness

LIN support and multiple serial interfaces ease mixed-protocol systems

48 I/O in compact 10x10 mm footprint supports dense control applications

Mature RL78 ecosystem with tools, libraries, and community support

Packaging

Type: 64-LFQFP (Low-Profile Quad Flat Package), 10x10 mm body

Supplier Device Package: 64-LFQFP (10x10)

Case: 64-LQFP/LFQFP, low profile, gull-wing leads on four sides

Material: Epoxy mold compound with copper leadframe; lead-free plating (RoHS3 compliant)

Size: Approx. 10 mm x 10 mm body; low profile height

Pin configuration: 64 leads around the perimeter; 48 programmable I/O, remaining pins for power, ground, and dedicated functions

Shipment: Tray packaging for assembly line efficiency

Lifecycle

Current status: Active and in mass production within the RL78/G13 family

Not nearing discontinuation based on available information at time of writing

Equivalent or alternative models: Pin-compatible and feature-variant options exist within the RL78/G13 and related RL78 families (different Flash/RAM sizes, temp grades, and peripheral mixes in the same 64-LFQFP footprint). Exact crosses depend on memory size, option code (#V0), temperature grade, and peripherals.
