MDT10P621
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 4K words of ROM, and 192 bytes
of static RAM.
2. Features
-PortB<7:4> interrupt on change
-CCP,SCM
u
TMR0 : 8-bit real time clock/counter
TMR1 : 16-bit real time clock/count
TMR2 : 8-bit clock/counter(internal)
u
4 types of oscillator can be selected by
programming option:
