TRF7960 Multi-Protocol Fully Integrated 13.56-MHz RFID Reader/Writer IC

The reader's protocol is set via control registers, allowing for fine-tuning of reader parameters. It supports up to 848 kbps data rates with onboard ISO protocol handling. Direct modes enable full AFE control and access to raw subcarrier data. The dual-input receiver architecture enhances communication robustness, with automatic and manual gain control options. Signal strength is available in the RSSI register. An SPI or parallel interface facilitates MCU communication. Hardware encoders and decoders use a 12-byte FIFO register, but can be bypassed for real-time processing. The device supports a wide supply voltage range and offers selectable transmitter power levels with OOK and ASK modulation. A built-in voltage regulator supplies up to 20 mA to power external circuits.
