1. General Description
This EPROM-Based 8-bit micro-controller uses a fully static CMOS design technology to achieve high speed, small size, low power and high noise immunity. On chip memory includes 0.5K words EPROM and80 bytes static RAM. Four comparator inputs with external Vref (not for 18 pin package) are also provided. u u u XTAL¡ÐStandard crystal oscillator HFXT¡ÐHigh frequency crystal oscillator 4 oscillator start-up time can be selected by programming option: 150 µs, 20 ms, 40 ms, 80 ms On-chip RC oscillator based Watchdog Timer(WDT) can be operated freely 12 I/O(for 18 pins package),14 I/O(for 20 pins package),16 I/O(for 22/24 pins package) pins with their own independent direction control
