MDT10C65
1. General Description 3. Applications
This ROM-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. The application areas of this MDT10C65 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.
2. Features 4. Pin Diagram
