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 inclu-des 1K words of ROM, and 41 bytes of

static RAM.

2. Features

The followings are some of the features on the

hardware and software :

‹ Fully COMS static design

‹ 8-bit data bus

‹ On chip EPROM size : 1 K words

‹ Internal RAM size : 47 bytes

(41 general purpose registers, 6 special

registers)

‹ 36 single word instructions

‹ 14-bit instructions

‹ 2-level stacks

‹ Operating voltage : 2.5 V ~ 5.0 V

‹ Operating frequency : 0 ~ 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

‹ Sleep Mode for power saving

‹ 5 types of oscillator can be selected by

programming option:

INTRC－Internal 4 MHz RC oscillator

RC－Low cost RC oscillator

LFXT－Low frequency crystal oscillator

XTAL－Standard crystal oscillator

HFXT－High frequency crystal oscillator

‹ 3 oscillator start-up time can be selected by

programming option:

20 ms, 40 ms, 80 ms

‹ 8-bit real time clock/counter(RTCC) with 8-bit

programmable prescaler

‹ On-chip RC oscillator based Watchdog

Timer(WDT)

‹ Wake-up from sleep on pin change

3. Applications

The application areas of this P53(D) range from

appliance motor control and high speed automotive

to low power remote transmitters/receivers, small

instruments, chargers, toy, automobile and PC

pe-ripheral … etc.
