Key Advantages

Low power consumption with wide voltage range (1.6V–5.5V) for battery and mains-powered designs

Mature RL78 ecosystem with strong toolchain and broad community support

Rich on-chip peripherals reduce external components and BOM cost

Internal oscillator simplifies clock design and saves board space

LINbus, UART, I2C, and CSI make it easy to interface with sensors, actuators, and networks

Industrial temperature grade (-40°C to +85°C) for robust use in harsh environments

RoHS3 compliance supports green and regulatory requirements

Stable long-life Renesas platform for high supply reliability

Packaging

Packaging type: Tape & Reel (TR) for automated SMT

Device package: 64-LQFP (LFQFP), 10 x 10 mm body size

Material: Molded plastic over copper lead frame, lead-free plating (RoHS3)

Pin configuration: 64 gull-wing leads; up to 48 GPIO; dedicated VCC/VSS; serial interfaces (UART, I2C, LIN, CSI); ADC inputs; PWM outputs; reset and clock pins

Lead pitch: standard 64-LQFP pitch (typically around 0.5 mm)

Mounting: Surface-mount, reflow compatible

Thermal characteristics: -40°C to +85°C ambient (TA); use good PCB copper and vias for heat spreading; no exposed thermal pad

Electrical highlights: 1.6V–5.5V supply, 32MHz operation, internal oscillator, integrated LVD and WDT for system safety

Lifecycle

Status: Active and in production based on latest available information; not nearing discontinuation

Equivalent or alternatives within Renesas:

- RL78/G13 family variants with the same 64-pin package and different Flash sizes (e.g., 128KB, 256KB, 512KB) and temperature/option codes

- RL78/G14 family for more performance and peripherals if you need extended features

- RL78/G23 family for newer ultra-low-power designs while keeping RL78 toolchain continuity

Pin-for-pin and feature matching depends on exact suffix and option codes. For a precise, drop-in cross reference list tailored to your design, please contact Y-IC via our website and our sales team will provide detailed part mappings and availability.
