1. General Description

This ROM-Based 8-bit micro-controller uses a

fully static CMOS technology process to

achieve high speed, small size, the low power

and high noise immunity.

On chip memory includes 2K words EPROM,

and 80 bytes 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 : 2.0 K words

‹ Internal RAM size : 80 bytes

(73 general purpose registers, 7 special

registers)

‹ 36 single word instructions

‹ 14-bit instructions

‹ 2-level stacks

‹ Operating voltage : 2.3 V ~ 6.0 V

‹ Operating frequency : 0 ~ 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 (POR),only available

while PED is Disable

‹ Power edge-detector Reset

‹ Sleep Mode for power saving

‹ 4 types of oscillator can be selected by

programming option:

RC－Low cost RC oscillator

LFXT－Low frequency crystal oscillator

XTAL－Standard crystal oscillator

HFXT－High frequency crystal oscillator

‹ 4 oscillator start-up time can be selected

by programming option:

150 μs, 20 ms, 40 ms, 80 ms

‹ 8-bit real time clock/counter(RTCC) with

8-bit programmable prescaler

‹ On-chip RC oscillator based Watchdog

Timer(WDT)

‹ 12 I/O pins with their own independent

direction control
