Supply voltage: 1.6V to 5.5V

RoHS: ROHS3 compliant

Series: RL78/G14

Base product number: R5F104

Key Advantages

Low power with wide voltage range, good for battery-powered and energy-sensitive products

Large on-chip Flash and RAM for complex firmware and future updates

Built-in EEPROM for parameter storage and data logging without external memory

Rich analog (ADC/DAC) and timers/PWM for precise control

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

Proven RL78 platform with strong ecosystem and long-term availability

Industrial temperature rating for robust performance in harsh environments

Simple clocking with internal oscillator reduces BOM and design complexity
