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 72 b ytes 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 eprom size : 1k words
? internal ram size : 72 bytes
? 36 single word instructions
? 14-bit instructions
? 2-level stacks
? operating voltage : 2.5 v ~ 5.5 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
? power edge-detector 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
