DATA SHEET DATA SHEET www.DataSheet4U.co m µPD6121, 6122 REMOTE CONTROL TRANSM ISSION CMOS IC MOS INTEGRATED CIRCUIT The µPD6121, 6122 are infrared remote control transmission ICs using the NEC transmission format that are ideally s uited for TVs, VCRs, audio equipment, a ir conditioners, etc. By combining exte rnal 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 co mpact remote control transmitters. The NEC transmission format consists of lea der codes, custom codes (16 bits), and data codes (16 bits). It can be used fo r various systems through d

ecoding by a microcontroller. * FEATUR ES • • • • Low-voltage operat ion: VDD = 2.0 to 3.3 V Low current dis sipation: 1 µA Max. (at standby) Custo m codes: 65,536 (set by external diodes and resistors) Data codes: • µPD612 1: 32 codes (single input), 3 codes (do uble input), expandable up to 64 codes through SEL pin • µPD6122: 64 codes (single input), 3 codes (double input), expandable up to 128 codes through SEL pin * • µPD6121, 6122 are transmi ssion code-compatible (NEC transmission format) with the µPD1913CNote, 1943GN ote, 6102GNote, and 6120CNote. • Pin compatibility: • µPD6121G-001 is pi n-compatible with the µPD1943G (Howeve r, capacitance of capacitor connected t o oscillator pin and other parameters v ary) • µPD6122G-001 is pin-compatibl e with the µPD6102G (However, capacita nce of capacitor connected to oscillato r pin and other parameters vary) • S tandard products (Ver. I, Ver. II speci fications) Note Provided for maintenanc e purpose only • When using this prod uct (in NEC transmission format), pleas e order custom codes from NEC. • New custom codes for the µPD6121G-002, µP D6122G-002 cannot be ordered. * The i nformation in this document is subject to change without notice.
