Built-in Remote Control Transmission Circuit 4-Bit Microcontroller
GENERAL DESCRIPTION
The MSM6641, powered by a single battery, is a 4-bit microcontroller fabricated in OKI’s low-
voltage CMOS technology. A remote-control output generator built into this device provides
remote-control output.
The MSM6641 is best suited to remote-control applications.

• Remote-control output port
:1
The remote-control output circuit consists of a carrier generator, a guide pulse and data
pulse generator, and an output waveform controller.
The remote control output can be provided by setting the control registers.
• Key-On Wake-Up function
Oscillation can be stopped to turn off microcontroller operation.
Application of predetermined input levels to the input ports turns on oscillation and
microcontroller operation.
