PD67, 67A, 68, 68A, 69
4-BIT SINGLE-CHIP MICROCONTROLLER
FOR INFRARED REMOTE CONTROL TRANSMISSION
MOS INTEGRATED CIRCUIT
DESCRIPTION
With their 2.0 V low-voltage operation, carrier generator for infrared remote control transmission, standby release
function through key input, and programmable timer, the
碌
PD67, 67A, 68, 68A, and 69 are ideal for infrared remote
control transmitters.
A one-time PROM product, the
碌
PD6P9, has also been provided for the
碌
PD67, 67A, 68, 68A, and 69 for program
evaluation or small-quantity production.
