Key Advantages

Very low power consumption typical of RL78 architecture

Wide supply range suits battery-powered and 5V systems

Rich on-chip peripherals reduce external components and cost

Built-in safety features (WDT, LVD, POR) improve reliability

Scalable RL78/G13 family simplifies migration and reuse

48 GPIO in a compact 64-pin footprint

Mature ecosystem with tools, libraries, and community support

Packaging

Type: 64-LQFP, tray packing

Material: Molded epoxy encapsulation with copper alloy leadframe; lead finish typically matte tin for RoHS3 compliance (see datasheet for exact finish)

Size: Body 12 x 12 mm; height and other dimensions per 64-LQFP standard

Pin configuration: 64 leads total; about 48 configurable GPIO; dedicated pins for power (VDD/VSS), reset, oscillator, ADC references, and serial interfaces (refer to datasheet pin map)

Lead pitch: Typical 0.5 mm for 64-LQFP (confirm exact pitch in datasheet)

Mounting: Surface mount, compatible with standard reflow soldering profiles

Thermal characteristics: No exposed thermal pad; heat dissipates through leads and PCB copper area. Thermal performance depends on board design. For θJA/θJC and derating, use the datasheet guidance.

Electrical properties: VCC 1.6V to 5.5V; internal oscillator available; ADC 10-bit; I/O levels compatible with the supply voltage. Follow datasheet for decoupling, clamp diodes, and ESD handling.

Lifecycle

Status: Part of the active RL78/G13 family based on publicly available information. Not flagged as nearing discontinuation at the time of writing. Availability can change; confirm with our sales team.

Equivalent or alternative models:

- Renesas RL78/G13 family variants with similar memory and pin count: R5F101LE, R5F101LF, R5F101LG series options (different option codes like #20, #30, etc., indicate speed, temperature grade, or packing). Pin-to-pin compatibility varies; verify with datasheets.

- Renesas RL78/G14 family for higher performance and more peripherals while keeping a similar programming model.

- Cross-vendor functional alternatives in the 16-bit class include Microchip PIC24 and TI MSP430 families with roughly 128KB Flash and comparable peripherals. Exact pinout and feature match require cross-checking.
