1. General Description

This EPROM-Based 8-bit micro-controller uses a fully

static CMOS technology process to achieve higher

speed and smaller size with the low power consumption

and high noise immunity. On chip memory includes 4K

words of ROM, and 192 bytes of static RAM.

2. Features

The followings are some of the features on the

hardware and software:

Fully CMOS static design

8-bit data bus

On chip EPROM size: 4.0 K words

Internal RAM size: 192 bytes

37 single word instructions

14-bit instructions

8-level stacks

Operating voltage: 2.5 V ~ 5.5 V (PRD Disable)

4.5 V ~ 5.5 V (PRD Enable)

Operating frequency: DC ~ 20 MHz

The most fast execution time is 200 ns under 20

MHz in all single cycle instructions except the

branch instruction

Addressing modes include direct, indirect and

relative addressing modes

Power-on Reset
