Overview

Description

RL78/G12 microcontrollers balance the industry's lowest level of consumption current (CPU: 63 μA/MHz, standby (STOP): 230 nA) and a high performance of 32.4 DMIPS (24 MHz). They have an on-chip oscillator, data flash, A/D converter, and more. Built-in safety features (function that detects illegal operation of hardware) enable support for the household appliance safety standard (IEC/UL 60730). With a 20 to 30-pin compact package lineup, these microcontrollers are perfect for sub-microcontrollers of small appliances and consumer and industrial equipment.

Features

  • Timer: 16-bit Timer (ch) x 8, 8-bit Timer (ch) x 4, Watchdog Timer (ch) x 1, 12-bit Interval Timer x 1 ch
  • PWM: PWM Output x 7
  • Analog function: 10-bit A/D Converter (ch) x 8
  • On-chip Oscillator Freq. (MHz): High-Speed: 1, 4, 8, 12, 16, 24MHz
    Low-speed: 15kHz
  • Others: Power-On Reset, Low Voltage Detection
