2005/6 VER1.3

1. General Description

This EPROM-Based 8-bit micro-controller

uses a fully static CMOS design technology

combines higher speeds and smaller size

with the low power and high noise immunity

of CMOS.

On chip memory system includes 1.0 K(for

MDT2010) bytes of ROM, and 32 bytes of

static RAM.

2. Features

(25 general purpose registers, 7 special

registers)

u 36 single word instructions

u 14-bit instructions

u 2-level stacks

u Operating voltage : 2.3V ~ 5.5 V

u Operating frequency : 0 ~ 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 Sleep Mode for power saving

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

8-bit programmable prescaler

u 4 types of oscillator can be selected by

programming option:
