概述

Q1. 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 consumption and high
noise immunity. On chip memory includes 4K words of
ROM, and 192 bytes of static RAM.
2. Features

? 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
? Capture, Compare, PWM module
? Synchronous serial port with SCM,I2C
? 12 interrupt sources:
-External INT pin
