Description
ELECTRONIC COMPONENT MODEL: UPD61153BF1
Product Category: IC Chips
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.
Specifications and features
• Low-voltage operation: V DD = 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 µPD1913C, 1943G, 6102G, and 6120C.
• 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)
Application Scenarios
The UPD61153BF1 can be used in various electronic systems such as TVs, VCRs, audio equipment, and air conditioners for remote control transmission purposes.
