MDT2005

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 :

u Fully COMS static design

u 8-bit data bus

u On chip ROM size : 512 words for MDT2005

u Internal RAM size : 32 bytes

(25 general purpose registers, 7 special registers)

u 36 single word instructions

u 14-bit instructions

u 2-level stacks

u Operating voltage : 2.3V ~ 6.3 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 8-bit real time clock/counter(RTCC) with 8-bit programmable prescaler

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
