New High-Frequency Multi-Standard RFID Reader ICs from TI -TRF7961

The high-frequency (13.56 MHz) radio frequency identification(RFID) standards such as ISO/IEC 14443A/B, ISO/IEC 15693, ISO/IEC 18000-3 and TI's contactless and Tag-It,  can now be implemented in one chip by Texas Instruments new TRF7960 multi-standard RFID Reader Chip. This RFID Reader Chips is designed for both fixed and handheld reader devices.

To improve range of reading between tag and reader, TI provides low noise digital and power amplifiers,  analog front end and data framing system  in it’s new chips. The dual receiver input of the TRF7960 RFID reader chips able to detect Phase Modulation and Amplitude Modulation.

TRF7960 RFID Reader use a single 13.56MHz crystal (other chips in this class commonly use two crystals). This feature contributes in reducing list of external components, reduce power consumption, takes up less space, and can therefore address sensitivity and noise attenuation issues. Other integrated functions include error checking, data formatting, framing and anti-collision support for multi-reader environments.

The TRF7960 IC operates between 2.7 to 5.5 Vdc input supply voltage and when in power down mode, consumption is less than 1 micro Amp while standby current is less than 120 micro Amp.

Packaging: standard 32-pin QFN (IC to board)
