1. General Description
-PortB<7:4> interrupt on change
-CCP,SCM
This EPROM-Based 8-bit micro-controller uses a fully static u A/D converter module:
CMOS technology process to achieve higher speed and
-5 analog inputs multiplexed into one A/D
smaller size with the low power consumption and high noise
converter
immunity. On chip memory includes 2K words of ROM, and
-8-bit resolution
128 bytes of static RAM.
u TMR0 : 8-bit real time clock/counter
2. Features
TMR1 : 16-bit real time clock/count
TMR2 : 8-bit clock/counter(internal)
The followings are some of the features on the hardware
and software :
u Fully CMOS static design
u 8-bit data bus
u On chip EPROM size : 2.0 K words
u Internal RAM size : 160 bytes
(128 general purpose registers, 32 special
registers)
u 37 single word instructions
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 On-chip RC oscillator based Watchdog Timer(WDT)
u 22 I/O pins with their own independent direction
control
u 14-bit instructions
u 8-level stacks
3. Applications
u Operating voltage : 2.5 V ~ 5.5 V (PRD Disable)
The application areas of this MDT10P72 range from
4.5 V ~ 5.5 V (PRD Enable)
appliance motor control and high speed auto-motive to low
u Operating frequency : DC ~ 20 MHz
power remote transmitters/receivers, pointing devices, and
u The most fast execution time is 200 ns under 20 telecommunications processors, such as Remote
MHz in all single cycle instructions except the controller, small instruments, chargers, toy, automobile
branch instruction
and PC peripheral … etc.
u Addressing modes include direct, indirect and
relative addressing modes
u Power-on Reset
u Power edge-detector Reset
u Power range-detector Reset
u Sleep Mode for power saving
u Capture,Compare,PWM module
u Synchronous serial port with SCM
u 8 interrupt sources:
-External INT pin
-TMR0 timer,TMR1 timer,TMR2 timer
-A/D conversion completion
