VER1.4

1. General Description

This ROM-Based 8-bit micro-controller

uses

a

fully

static

CMOS

design

technology combines higher speed and

smaller size with the low power and high

noise immunity of CMOS.

On chip memory system includes 2.0 K

bytes of ROM, and 80 bytes of static RAM.

2. Features

The followings are some of the features on

the hardware and software :

u Fully CMOS static design

u 8-bit data bus

u On chip ROM size : 2.0 K words

u Internal RAM size : 80 bytes

(73 general purpose registers, 7 special

registers)

u 34 single word instructions

u 12-bit instructions

u 2-level stacks

u Operating voltage : 2.3 V ~ 6.3 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 4 oscillator start-up time :

150

µs, 20 ms, 40 ms, 80 ms

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

8-bit programmable prescaler

u 4 types of oscillator can be selected by

code options :

RC－Low cost RC oscillator

LFXT－Low frequency crystal oscillator

XTAL－Standard crystal oscillator

HFXT－High frequency crystal oscillator

u On-chip RC oscillator based Watchdog

Timer(WDT) can be operated freely

u Pull up resistors for the following pins :

PA0~PA3, PB0~PB7, /MCLR, RTCC

u Pull down resistors for the following

pins :

PA0~PA3, PB0~PB7, RTCC

u 12 I/O pins with their own independent

direction control

3. Applications

The application areas of this MDT1030

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.
