MDT10F630
1. General Description
This 8-bit Micro-controller uses a fully static
CMOS technology to achieve high speed, small
size, low power and high noise immunity.
On chip memory includes 1 K words of Flash
ROM, and 128 bytes of EEPROM, and 64 bytes
of static RAM.
The application areas of this MDT10F630 range
from appliance motor control and high speed
automotive
to
low
power
remote
and
toy,
transmitters/receivers,
controller,
small
pointing
devices,
chargers,
telecommunications processors, such as Remote
instruments,
automobile and PC peripheral … etc.
