MDT10P73(BB)
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 4K words of ROM, and 192 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: 4.0 K words
Internal RAM size: 192 bytes
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
11 interrupt sources:
-External INT pin
-TMR0 timer, TMR1 timer, TMR2 timer
-A/D conversion completion
-Port B<7:4> interrupt on change
-CCP1, CCP2, SCM, USAR, USAT
A/D converter module:
-5 analog inputs multiplexed into one A/D
converter
-8 bit resolution
TMR0: 8-bit timer/counter
TMR1: 16-bit timer/counter
TMR2: 8-bit timer
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 MDT10P73 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.
