MOS INTEGRATED CIRCUIT

µ

PD62

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

µ

PD62 is suitable for infrared remote

control transmitters.

For the

µ

PD62, we have made available the one-time PROM product

µ

PD6P4B for program evaluation or small-

quantity production.
