Overview

The device is an 8-bit high performance RISC-like microcontroller designed for multiple I/O product applications. It is particularly suitable for use in products such as washing machine controllers and home appliances.

  • Operating voltage:
  • Up to 0.5ms instruction cycle with 8MHz system clock fSYS=4MHz: 3.3V~5.5V fSYS=8MHz: 4.5V~5.5V at VDD=5V
  • 23 bidirectional I/O lines (max.)
  • 1 interrupt input shared with an I/O line
  • 16-bit programmable timer/event counter with overflow
  • 8-level subroutine nesting
  • 8 channels 10-bit resolution (9-bit accuracy) A/D con- verter interrupt and 7-stage prescaler
  • 2-channel (6+2)/(7+1)-bit PWM output shared with two I/O lines
  • On-chip crystal and RC oscillator
  • Watchdog Timer
