Power-on Reset
1. General Description
Power edge-detector Reset
This ROM-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 72 bytes of
static RAM.
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
