MDT10C23
XTAL-Standard crystal oscillator
1. General Description
HFXT-High frequency crystal oscillator
u
4 oscillator start-up time can be selected by
programming option:
This ROM-Based 8-bit micro-controller uses a fully
static CMOS design technology to achieve high
speed, small size, low power and high noise
immunity.

Timer(WDT) can be operated freely
12 I/O(for 18 pins package),14 I/O(for 20 pins
package),16 I/O(for 22/24 pins package) pins
with their own independent direction control
On chip memory includes 2K words ROM and80
bytes static RAM.
Four comparator inputs with external Vref (not for 18
pin package) are also provided.
