PD66P04B
4-BIT SINGLE-CHIP MICROCONTROLLER
FOR INFRARED REMOTE CONTROL TRANSMISSION
DESCRIPTION
The
碌
PD66P04B is a microcontroller for infrared remote control transmitters which is provided with a one-time
PROM as the program memory.
Because users can write programs for the
碌
PD66P04B, it is ideal for program evaluation and small-scale
production of the application systems using the
碌
PD6604.
When reading this document, also refer to the
碌
PD6604 Data Sheet (U11281E).

鈥?Built-in carrier generation circuit for infrared remote control
APPLICATION
Infrared remote control transmitter (for AV and household electric appliances)
Because the
碌
PD66P04B uses an RC oscillation system clock, its accuracy and stability are lower than
the models using ceramic oscillation.
In applications where the clock accuracy and stability pose a problem, use the
碌
PD61P34B (ceramic
oscillation type).
