TRF7960RHBR

TEXAS INSTRUMENTS  TRF7960RHBR  芯片, RFID模拟前端, 13.56MHZ, QFN32

The is a Fully Integrated 13.56MHz RFID Reader/Writer IC configured by selecting the desired protocol in the control registers. Built-in programming options make it suitable for a wide range of applications for proximity and vicinity RFID systems. Direct access to all control registers allows fine tuning of various reader parameters as needed. A parallel or serial interface can be implemented for communication between the MCU and reader. Transmit and receive functions use internal encoders and decoders with a 12-byte FIFO register. For direct transmit or receive functions, the encoders/decoders can be bypassed so the MCU can process the data in real time. The transmitter has selectable output power levels of 100mW 20dBm or 200mW 23dBm into a 50- load 5V supply and is capable of ASK or OOK modulation. Integrated voltage regulators ensure power-supply noise rejection for the complete reader system.
