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 2K words of ROM, and 

128 bytes of static RAM.

2. Features

u 8-level stacks

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

 4.5 V ~ 5.5 V (PRD Enable)

u Operating frequency : DC ~ 20 MHz

u The most fast execution time is 200 ns under 20 

MHz in all single cycle instructions except the

branch instruction

u Addressing modes include direct, indirect and 

relative addressing modes

u Power-on Reset

u Power edge-detector Reset

u Power range-detector Reset
