MDT10P716
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 2K words of ROM, and 128
bytes of static RAM.
converter
-8-bit resolution
TMR0: 8-bit real time clock/counter
TMR1: 16-bit real time clock/counter
TMR2: 8-bit clock/counter
4 types of oscillator can be selected by
programming option:
RC－Low cost RC oscillator
LFXT－Low frequency crystal oscillator
XTAL－Standard crystal oscillator
