概述

1. General Description
This Flash ROM-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, 256 bytes of EEPROM 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 FLASH ROM size: 4.0 K words
?  Internal RAM size: 192 bytes
?  Internal EEPROM size: 256 bytes
?  37 single word instructions
?  14-bit instructions
?  8-level stacks
?  Operating voltage: 2.5 V ~ 5.5 V (PEDH Disable)
4.5 V ~ 5.5 V (PEDH 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
?  Sleep Mode for power saving
?  Capture, Compare, PWM module
?  7 interrupt sources:
-External INT pin
-TMR0 timer, TMR1 timer, TMR2 timer
-A/D conversion completion
-Port B<7:4> interrupt on change
-CCP1

programming option:
IRC ? Internal 16MHz RC oscillator
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)
?  22/24/26/28 I/O pins with their own independent
direction control
