µPD6121, 6122
REMOTE CONTROL TRANSMISSION CMOS IC
MOS INTEGRATED CIRCUIT
The µPD6121, 6122 are infrared remote control transmission ICs using the NEC transmission format that are ideally suited for TVs, VCRs, audio equipment, air conditioners, etc. By bining external diodes and resistors, a maximum of 65,536 custom codes can be specified. These ICs e in small packages, thus facilitating the design of light and pact remote control transmitters. The NEC transmission format consists of leader codes, custom codes (16 bits), and data codes (16 bits). It can be used for various systems through decoding by a microcontroller.
