MDT90P01
1. General Description
This EPROM-Based 4-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 0.5K words of ROM, and 30 nibbles
of static RAM.
Sleep Mode for power saving
oscillator start-up time : 20ms
8 bit real time clock/counter(RTCC) with 8-bit
programmable prescaler
On-chip RC oscillator based Watchdog
Timer(WDT)
Wake-up from sleep on pin change
