General Description

The device is an 8-bit high performance RISC-like

microcontroller designed for multiple I/O product appli-

cations. It is particularly suitable for use in products

such as washing machine controllers and home appli-

ances. A HALT feature is included to reduce power con-

sumption.

Features

· Operating voltage:

fSYS=4MHz: 2.2V~5.5V

fSYS=8MHz: 4.5V~5.5V

· 19 bidirectional I/O lines (max.)

· 1 interrupt input shared with an I/O line

· 8-bit programmable timer/event counter with over-

flow interrupt and 7-stage prescaler

· On-chip crystal and RC oscillator

· Watchdog Timer

· 2048´14 program memory ROM

· 64´8 data memory RAM

· Supports PFD for sound generation

· HALT function and wake-up feature reduce power

consumption

· Up to 0.5ms instruction cycle with 8MHz system clock

at VDD=5V

· 6-level subroutine nesting

· 8 channels 9-bit resolution (8-bit accuracy) A/D con-

verter

· 1-channel (6+2)/(7+1)-bit PWM output shared with

two I/O lines

· Bit manipulation instruction

· 14-bit table read instruction

· 63 powerful instructions

· All instructions in one or two machine cycles

· Low voltage reset function

· I2C BUS (slave mode)

· 24-pin SKDIP/SOP package
