REMOTE CONTROL TRANSMISSION CMOS IC;

REMOTE CONTROL TRANSMISSION CMOS ICThe 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.\nThe 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.FEATURES\n? Low-voltage operation: VDD = 2.0 to 3.3 V\n? Low current dissipation: 1 μA Max. (at standby)\n? Custom codes: 65,536 (set by external diodes and resistors)\n? Data codes:\n?? ? μPD6121: 32 codes (single input), 3 codes (double input), expandable up to 64 codes through SEL pin\n?? ? μPD6122: 64 codes (single input), 3 codes (double input), expandable up to 128 codes through SEL pin\n? μPD6121, 6122 are transmission code-compatible (NEC transmission format) with the μPD1913CNote, 1943GNote, 6102GNote, and 6120CNote.\n? Pin compatibility:\n?? ? μPD6121G-001 is pin-compatible with the μPD1943G (However, capacitance of capacitor connected to\noscillator pin and other parameters vary)\n?? ? μPD6122G-001 is pin-compatible with the μPD6102G (However, capacitance of capacitor connected to\noscillator pin and other parameters vary)\n? Standard products (Ver. I, Ver. II specifications)
