The UPD61130AS1-104-F6 is a remote control encoder/transmitter integrated circuit (IC) manufactured by NEC. It is designed for use in infrared (IR) remote control systems, encoding button presses into a specific format for transmission to a receiver. This IC facilitates communication between a user operating a remote and a controlled device such as a television, DVD player, or other electronic appliance.

Applications

• Television remote controls
• DVD player remote controls
• Set-top box remote controls
• Audio equipment remote controls
• Air conditioner remote controls
• Universal remote controls

Features

• Infrared (IR) remote control transmission
• Encoding of button presses
• Low power consumption
• Multiple key input support
• Oscillator circuit for carrier frequency generation
• Programmable customer code

Benefits

• Enables wireless control of electronic devices
• Simplifies remote control design
• Extends battery life due to low power consumption
• Allows for a variety of functions to be controlled
• Facilitates customization for specific applications

Additional Details

The UPD61130AS1-104-F6 operates by scanning the input keys, encoding the pressed key along with a customer code, and then modulating this information onto an infrared carrier frequency (typically around 38kHz). The modulated signal is then transmitted by an IR LED. The customer code is pre-programmed to ensure that the remote only controls the intended device. This particular part number likely represents a specific configuration or mask option of the UPD61130AS1 family, tailored to a particular manufacturer or application. The device typically operates on a low voltage power supply. Pinouts include inputs for buttons, power supply, ground, oscillator connections and IR output.
