µPD6121, 6122
REMOTE CONTROL TRANSMISSION CMOS IC
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.

FEATURES
Low-voltage operation: VDD = 2.0 to 3.3 V
Low current dissipation: 1 µA Max. (at standby)
Custom codes: 65,536 (set by external diodes and resistors)
Data codes:
µPD6121: 32 codes (single input), 3 codes (double 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 transmission code-compatible (NEC transmission format) with the µPD1913CNote, 1943GNote,
6102GNote, and 6120CNote.
Pin compatibility:
µPD6121G-001 is pin-compatible with the µPD1943G (However, capacitance of capacitor connected to
oscillator pin and other parameters vary)
µPD6122G-001 is pin-compatible with the µPD6102G (However, capacitance of capacitor connected to
oscillator pin and other parameters vary)
Standard products (Ver. I, Ver. II specifications)
