Detailed Description

16-bit RL78/G13 microcontroller with 96 KB on-chip Flash, 8 KB RAM, wide 1.6–5.5 V supply range, up to 32 MHz operation, rich peripherals (DMA, LVD, POR, PWM, WDT), and multiple serial interfaces (CSI, I2C, LIN, UART/USART). It integrates a multi-channel A/D converter, internal oscillator, and offers 48 programmable I/O pins in a compact 64-pin LQFP package. Designed for low power, reliable embedded control from -40°C to +85°C.
