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 combining external diodes and resistors, a maximum of 65,536 custom codes can be specified. These ICs come in small packages, thus facilitating the design of light and compact 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.
