Product Summary

The UPD6121G001 is an infrared remote control transmission IC 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. The UPD6121G001 comes in small packages, thus facilitating the design of light and compact remote control transmitters.

Parametrics

UPD6121G001 absolute maximum ratings: (1)Supply voltage VDD: –0.3V to +6.0V; (2)Input voltage VI: –0.3V to VDD + 0.3V; (3)Power dissipation PD: 250mW; (4)Operating ambient temperature TA: –20℃ to +75℃; (5)Storage temperature Tstg: –40℃ to +125℃.

Features

UPD6121G001 features: (1)Low-voltage operation: VDD = 2.0 to 3.3 V; (2)Low current dissipation: 1mA Max. (at standby); (3)Custom codes: 65,536 (set by external diodes and resistors); (4)Data codes: UPD6121: 32 codes (single input), 3 codes (double input), expandable up to 64 codes through SEL pin, UPD6122: 64 codes (single input), 3 codes (double input), expandable up to 128 codes through SEL pin; (5)UPD6121, 6122 are transmission code-compatible (NEC transmission format) with the mPD1913CNote, 1943GNote, 6102GNote, and 6120CNote.; (6)Pin compatibility:; (7)UPD6121G-001 is pin-compatible with the UPD1943G (However, capacitance of capacitor connected to oscillator pin and other parameters vary), UPD6122G-001 is pin-compatible with the UPD6102G (However, capacitance of capacitor connected to oscillator pin and other parameters vary); (8)Standard products (Ver. I, Ver. II specifications).
