UPD6134

DATA SHEET µPD6133, 6134 4-BIT SINGLE-CHIP MICROCONTROLLER FOR INFRARED REMOTE CONTROL TRANSMISSION MOS INTEGRATED CIRCUIT DESCRIPTION Equipped with low-voltage 1.8V operation, a carrier generation circuit for infrared remote control transmission, a standby release function through key entry, and a programmable timer, the µPD6133 and 6134 are suitable for infrared remote control transmitters. For the µPD6133 and 6134, we have made available the one-time PROM product µPD61P34B for program evaluation or small-quantity production.
