1. General Description
This EPROM-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 :
? Fully CMOS static design
? 8-bit data bus
? On chip ROM size : 2 K words
? Internal RAM size : 80 bytes
(72 general purpose, 8 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 oscillator start-up time :
150 μs, 20 ms, 40 ms, 80 ms
? 8-bit real time clock/counter(RTCC)
with 8-bit programmable prescaler
? 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
? On-chip RC oscillator based
Watchdog Timer(WDT) can be operated
freely
? 20 I/O pins with their own
independent direction control
3. Applications
The application areas of this MDT2020
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.
