MDT2030

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 :

u Fully CMOS static design

u 8-bit data bus

u On chip EPROM size : 2.0 K words

u Internal RAM size : 80 bytes

(73 general purpose registers, 7 special

registers)

u 36 single word instructions

u 14-bit instructions

u 2-level stacks

u Operating voltage : 2.3 V ~ 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 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

u 4 oscillator start-up time can be selected by

programming option:

150 µs, 20 ms, 40 ms, 80 ms

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

programmable prescaler

u On-chip RC oscillator based Watchdog

Timer(WDT)

u 12 I/O pins with their own independent

direction control

3. Applications

The application areas of this MDT2030 range from

appliance motor control and high speed automotive

to low power remote transmitters/receivers, pointing

devices, and telecommunications processors, such
