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 consumption and high noise
immunity. on chip memory includes 1k words of rom, and 64 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 rom size: 1k words (000h~3ffh)
internal ram size: 64 bytes (10h~4fh)
37 single word instructions
14-bit instructions
8-level stacks
operating frequency: dc~20mhz
the most fast
execution time is
200ns under
20mhz 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 (2.0v)
sleep mode for power saving
5 types of oscillator can be selected by
programming option:
intrc-internal 8mhz/4mhz/1mhz/455khz
rc-low cost rc oscillator
lfxt-low frequency crystal oscillator
xtal-standard crystal oscillator
hfxt-high frequency crystal oscillator
8-bit real time clock/counter (t0ci) with 8-bit programmable
prescaler
on-chip rc oscillator based watchdog timer(wdt)
four interrupt source:
-external int pin (pb0)
-timer0
-pb5~1 interrupt on pin change
-pa5~0 interrupt on pin change
3. applications
the application areas of this mcu range from appliance motor
control and high speed automotive to low power remote
transmitters/receivers, small instruments, chargers, toy,
automobile and pc peripheral … etc.
