Overview

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 µPD64A and 65 are suitable for infrared remote control transmitters. For the µPD64A and 65, we have made available the one-time PROM product µPD6P5 (under development) for program evaluation or small-quantity production.
