BC7215/BC7215A Universal IR Remote Decoder/Encoder
New Release: BC7215A Offline Air Conditioner Control Library
- Free Of Charge
- 100% Offline
- IR Command Parsing
- Future Proof
- Provided As C Source
- Small Footprint
- Low System Requirements
The BC7215 is capable of automatically identifying and decoding over 99.5% of air conditioner remote control protocols and over 98% of various audio/video and other infrared controlled devices. Upon reception, it directly decodes and outputs raw data; conversely, it can transmit data over infrared signals in a specified format simply by inputting raw data.
Due to its support for raw data input and output, it is also suitable for infrared data communication.
The BC7215 utilizes a UART interface, enabling direct connection with various MCUs, embedded systems, and Linux, Android, or Windows platforms without the need for low-level drivers or complex I/O-level programming.
- Automatic Recognition: Automatically identifies IR encoding formats.
- Raw Data I/O: Supports direct input and output of raw data.
- Bidirectional Communication: Suitable for bidirectional IR data communication.
- Universal Compatibility: UART interface works with a wide range of hardware and software systems.
- Integrated Hardware: Built-in IR transmitter driver and carrier generator.
- Operating Voltage: 2.7–5.5V
- Package: SO8
Typical Applications:
- Self-learning Remotes: Universal or learning remote controls.
- Custom Systems: Proprietary IR remote control systems with user-defined protocols.
- Universal IR Devices: IR controlled devices capable of pairing with any remote control.
- IoT Hubs: IoT Infrared Control Centers (IR Blasters).
- Data Link: Infrared data transmission.

Waveform(database) Converter API
We provide a free, web-based Conversion API.
Use Cases:
Integration with online IR Code Database: Converts waveform data provided by code libraries into BC7215(A) commands, enabling the chip to generate the specific waveform.
Advanced Decoding: Due to the complexity of infrared protocols, a very small number of formats cannot be decoded directly by the BC7215(A) chip. In these cases, the waveform can be sent to the API to retrieve the format information and raw data.
How it Works: Various IR code library services exist on the market, allowing users to retrieve remote control waveform data based on a device’s brand and model. Our service bridges the gap by converting this raw waveform data into BC7215 commands, enabling the chip to transmit the exact infrared waveform.
Benefits of the Conversion Service:
Universal Compatibility: Works with various infrared code libraries.
Significant Storage Reduction: Storing raw library data locally typically requires hundreds of bytes per key. In contrast, the converted BC7215 format requires only 33 bytes of format information per remote, and merely 2–32 bytes per key. This reduces local storage requirements by over 90%.
