Key Features

Core: Renesas RL78, 16-bit, up to 32 MHz

Memory: 192KB FLASH, 16KB RAM, 8KB EEPROM/data flash

I/O: 48 GPIOs with flexible pin functions

Analog: 12-channel A/D with selectable 8/10-bit resolution

Peripherals: DMA, PWM timers, watchdog timer (WDT), power-on reset (POR), low-voltage detector (LVD)

Connectivity: CSI (SPI-like), I2C, LINbus, UART/USART

Oscillator: Internal clock; supports external crystal if needed

Supply voltage: 2.4 V to 5.5 V

Temperature: -40°C to +105°C (TA)

Package: 64-LQFP (12 x 12 mm), 0.5 mm lead pitch

Compliance: RoHS3

Key Advantages

Low power 16-bit architecture for long battery life and cool operation

Large FLASH (192KB) and integrated EEPROM/data flash enable complex firmware and reliable data storage

Rich peripheral set reduces external components and BOM cost

Wide supply range and industrial temperature rating fit harsh environments

Multiple serial interfaces for easy system integration (SPI/CSI, I2C, UART, LIN)

Stable internal oscillator simplifies design and saves board space

Mature RL78 ecosystem with tools, libraries, and long-term support

Packaging

Type: 64-pin LQFP for surface-mount

Material: Lead-free molded epoxy body; copper alloy leadframe; matte-tin lead finish (RoHS3 compliant)

Size: 12 mm x 12 mm body; approximately 1.4 mm body thickness

Pin configuration: 64 leads at 0.5 mm pitch; dedicated VDD/VSS power pins; oscillator pins (XCIN/XCOUT); reset; multiple multiplexed GPIOs and serial interfaces

Thermal characteristics: Designed for standard LQFP thermal performance; follow datasheet guidelines for PCB copper area and thermal vias for best heat spreading; observe derating at high ambient temperatures

Electrical properties: 2.4–5.5 V supply; internal oscillator available; ESD protection integrated on I/O; low-power modes supported for reduced current in sleep/stop states

Shipment: Tape & Reel (TR) for automated pick-and-place

Lifecycle

Status: Active and widely used in production. Not near discontinuation based on current industry status.

Equivalents and alternatives: Pinand tool-compatible options exist within the RL78/G13 64-pin family with different FLASH sizes and peripheral mixes. There are also upward-compatible devices in RL78/G14 for more performance and timers, and cost-optimized RL78/G11 options for simpler needs.

Exact cross part numbers depend on required FLASH/RAM size, EEPROM/data flash options, and specific peripheral usage.
