、
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
EPROM, and 176 bytes of static RAM.
The application areas of this MDT11P0122
range from appliance motor control and high
speed automotive to low power remote
transmitters/receivers
and
tele-
communications processors, such as
Remote controller, small instruments, toy,
automobile and keyboard … etc.
