1. General Description

ꢀ Sleep Mode for power saving

ꢀ 8-bit real time clock/counter(RTCC)

with 8-bit programmable prescaler

ꢀ 4 types of oscillator can be selected

by programming option:

This EPROM-Based 8-bit micro-controller

uses a fully static CMOS design

technology to achieve high speed, small

size, low power and high noise immunity.

On chip memory includes 2K words

EPROM and 80 bytes static RAM.

RC－Low cost RC oscillator

LFXT－Low frequency crystal oscillator

XTAL－Standard crystal oscillator

EXT-R－Low cost R oscillator

Four comparator inputs with external Vref

(not for 18 pin package) are also provided.

ꢀ 2 oscillator start-up time can be

selected by programming option:

EXT-R、RC：150 μs,20ms

2. Features

XT、LF

：20ms,80ms

ꢀ Fully CMOS static design

ꢀ 8-bit data bus

ꢀ On-chip RC oscillator based

Watchdog Timer(WDT) can be

operated freely

ꢀ On chip EPROM size : 2 K words

ꢀ Internal RAM size : 80 bytes

(72 general purpose registers, 8

special registers)

ꢀ 12 I/O(for 18 pins package),14 I/O(for

20 pins package),16 I/O(for 22/24 pins

package) pins with their own

independent direction control

ꢀ 16 I/O pins own independent weak

pull-high and can be enabled by

software.

ꢀ 36 single word instructions

ꢀ 14-bit instructions

ꢀ 2-level stacks

ꢀ Operating voltage : 2.3V ~ 5.5 V

ꢀ Operating frequency : 0 ~ 20 MHz

ꢀ The most fast execution time is 200 ns

under 20 MHz in all single cycle

instructions except

ꢀ WDT can be enabled by software if

WDT Disable is selected in user

option.

the branch instruction

3. Applications

ꢀ Addressing modes include direct,

indirect and relative addressing

modes

This MDT10P223 can be used in appliance

motor control, high speed automotive,

remote transmitters/receivers, pointing

devices, telecommunications, small

instruments, chargers, toys, automobile

and PC peripheral … etc

ꢀ Power-on Reset (POR),

ꢀ 4 Channel comparator

ꢀ Power edge-detector Reset

ꢀ 4 types of power edge-detector reset:

1.8v , 2.1v , always enable 1.8v and
