MDT2030CF

ROM-Based 8-bit micro-controller

Unspecified 

MDT2030(CF)

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

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 as

Remote controller, small instruments,

chargers, toy, automobile and PC

peripheral … etc.
