MDT2002G

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.

Features

The followings are some of the features on the hardware and software :
Fully COMS static design
8-bit data bus
On chip ROM size : 512 words for MDT2005
Internal RAM size : 32 bytes(25 general pur pose registers, 7 special registers)
36 single word instructions
14-bit instructions
2-level stacks
Operating voltage : 2.3V ~ 6.3 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
Power edge-detector Reset
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:
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 ms, 20 ms, 40 ms, 80 ms
On-chip RC oscillator based Watchdog Timer(WDT) can be operated freely
12 I/O pins with their own independent direction control

Applications
The application areas of this MDT2005 range from appliance motor control and high speed
automot ive to low power remote transmitters/receivers, pointing devices, and
elecommunications processors, such as Remote controller, small instruments, chargers, toy,
automobile and PC peripheral … etc.
