PD6604
4-BIT SINGLE-CHIP MICROCONTROLLER
FOR INFRARED REMOTE CONTROL TRANSMISSION
DESCRIPTION
Equipped with low-voltage 1.8 V operation, a carrier generation circuit for infrared remote control transmission,
a standby release function through key entry, and a programmable timer, the
碌
PD6604 is suitable for infrared remote
control transmitters.
For the
碌
PD6604, we have made available the one-time PROM product
碌
PD66P04B for program evaluation or
small-quantity production.

APPLICATION
Infrared remote control transmitter (for key-less entry)
Because the
碌
PD6604 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
PD6134 (ceramic
oscillation type).
