MDT2005(JG)
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 0.5 K(for
MDT2005) 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 : 512 words for
MDT2005
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:
RCÑLow cost RC oscillator

direction control
3. Applications
The application areas of this MDT2005
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.
