1. General Description 

This EPROM-Based 8-bit micro-controller uses a fully static 

CMOS technology process to achieve higher speed and 

smaller size with the low power consumption and high 

noise immunity. On chip memory includes 2K words of 

ROM, and 128 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 EPROM size : 2.0 K words 

‹ Internal RAM size : 160 bytes 

(128 general purpose registers, 32 special 

registers) 

‹ 37 single word instructions 

‹ 14-bit instructions 

‹ 8-level stacks 

‹ Operating voltage : 2.5 V ~ 5.5 V (PRD Disable) 

 4.5 V ~ 5.5 V (PRD Enable) 

‹ Operating frequency : DC ~ 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 

‹ Power range-detector Reset 

‹ Sleep Mode for power saving 

‹ Capture,Compare,PWM module 

‹ Synchronous serial port with SCM 

‹ 8 interrupt sources: 

 -External INT pin 

 -TMR0 timer,TMR1 timer,TMR2 timer 

 -A/D conversion completion

-PortB<7:4>interrupt on change 

 -CCP,SCM 

‹ A/D converter module: 

 -5 analog inputs multiplexed into one A/D 

 converter 

 -8-bit resolution 

‹ TMR0 : 8-bit real time clock/counter 

TMR1 : 16-bit real time clock/count 

TMR2 : 8-bit clock/counter(internal) 

‹ 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 

‹ On-chip RC oscillator based Watchdog 

Timer(WDT) 

‹ 22 I/O pins with their own independent direction 

control 

3. Applications 

The application areas of this MDT10P72 range from 

appliance motor control and high speed auto-motive to 

low power remote transmitters/receivers, pointing 

devices, and telecommunications processors, such as 

Remote controller, small instruments, chargers, toy, 

automobile and PC peripheral … etc.
