概述

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
consump-tion and high noise immunity. On chip
memory incl-udes 1K words of ROM, and 68 b ytes 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 : 1.0 K words
? Internal RAM size : 84 bytes
(68 general purpose registers, 16 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
? Four interrupt sources:
-External INT pin
-TMR0 timer
-A/D conversion completion
-PortB<7:4>interrupt on change
? A/D converter module:
-Four analog inputs multiplexed into one A/D
converter
-8-bit resolution
? 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
? 8-bit real time clock/counter(RTCC) with 8-bit
programmable prescaler
? On-chip RC oscillator based Watchdog
Timer(WDT)
? 13 I/O pins with their own independent
direction control
3. Applications
The application areas of this MDT2051 range from
appliance motor control and high speed automotive
to low power remote transmitters/receivers, pointing
devices, and telecommunications processors, such
as Remote controller, small instruments, chargers,
toy, automobile and PC peripheral … etc.
