4-BIT SINGLE-CHIP MICROCONTROLLER
FOR INFRARED REMOTE CONTROL TRANSMISSION
DESCRIPTION
Equipped with low-voltage 2.0 V operation, a carrier generation circuit for infrared remote control transmission,
a standby release function through key entry, and a programmable timer, the
μ
PD64A and 65 are suitable for infrared
remote control transmitters.
For the
μ
PD64A and 65, we have made available the one-time PROM product
μ
PD6P5 (under development)
for program evaluation or small-quantity production.
