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

The followings are some of the features

on the hardware and software :

‹ Fully CMOS static design

‹ 8-bit data bus

‹ On chip ROM size : 1K words for

MDT2010

‹ Internal RAM size : 32 bytes

(25 general purpose registers, 7 special

registers)

‹ 36 single word instructions

‹ 14-bit instructions

‹ 2-level stacks

‹ Operating voltage : 2.3V ~ 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 (PED)

‹ Sleep Mode for power saving

‹ 8-bit real time clock/counter(RTCC)

with 8-bit programmable prescaler

‹ 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

‹ On-chip RC oscillator based

Watchdog Timer(WDT) can be operated

freely

‹ 12 I/O pins with their own independent

direction control

3. Applications

The application areas of this MDT2010

range from appliance motor control and

high speed automotive to low power

remote transmitters/receivers, pointing

devices, and telecommunications

processors, such as Remote controller,

small instruments, chargers, toy,

automobile and PC peripheral … etc.
