台湾麦肯单片机 MDT10P509 兼容 PIC12C508A PIC12C509A

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 : 41 bytes

‹ 36 single word instructions

‹ 14-bit instructions

‹ 2-level stacks

‹ Operating voltage : 2.5 V ~ 5.0 V

‹ Operating frequency : 4 MHz or 8 MHz

‹ The most fast execution time is 500 ns under 8

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

‹ Oscillator mode:

INTRC－Internal 4/8 MHz RC oscillator

‹ Power on start-up time : 20 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
