At 32 MHz the RL78 core executes 16-bit instructions with a single-cycle hardware multiplier — enough throughput for a PID loop or Modbus frame parsing without a DMA offload. ## Peripheral set and I/O count for a control board 48 general-purpose I/O lines plus a 12-channel 10-bit ADC and a 2-channel 8-bit DAC cover analog front-end and digital interface needs on a single chip — the CSI, I²C, LINbus, and UART/USART blocks handle sensor buses and actuator commands without external transceivers for most low-voltage links. On-chip DMA, PWM, and WDT reduce CPU overhead for periodic tasks — the PWM timers can drive a small DC motor or LED dimmer directly from the GPIO pads. The part is ROHS3 compliant, and the RL78/G14 series has broad second-source and cross-reference coverage across the Renesas portfolio — if a BOM hedge is needed, the same package and pinout is shared with other flash-density variants in the family.","metaTitle":"R5F104LFAFP#10 Renesas RL78/G14 MCU, 32 MHz, 96 KB Flash","metaDescription":"R5F104LFAFP#10 Renesas RL78/G14 16-bit MCU, 32 MHz, 96 KB Flash, 12 KB RAM, 8 KB EEPROM, 48 I/O, 64-LQFP.
