1 / 68 page  TRF7960A www.ti.com SLOS732 – JUNE 2011 MULTI-PROTOCOL FULLY INTEGRATED 13.56-MHz RFID READER/WRITER IC Check for Samples: TRF7960A 1 Introduction 1.1 Features 123 • Completely Integrated Protocol Handling for • Dual Receiver Architecture With RSSI for ISO15693, ISO18000-3, ISO14443A/B, NFC Elimination of "Read Holes" and Adjacent Forum Device Types 1 to 4, and FeliCa Reader System/Ambient In-Band Noise Detection • Input Voltage Range: 2.7 VDC to 5.5 VDC • Programmable Power Modes for Ultra-Low • Programmable Output Power: Power System Design (Power Down <0.5 µA) +20 dBm (100 mW) or +23 dBm (200 mW) • Parallel or SPI Interface • Programmable I/O Voltage Levels: 1.8 VDC to 5.5 VDC • Integrated Voltage Regulator for Microcontroller Supply • Programmable System Clock Frequency Output (RF, RF/2, RF/4) • Temperature Range: -40°C to +110°C • Programmable Modulation Depth • 32-Pin QFN Package (5 mm x 5 mm) (RHB) 1.2 Applications • Secure Access Control • Product Authentication • Contactless Payment Systems • Passport Reader Systems • Medical Systems • Remote Sensor Applications 1.3 Description The TRF7960A is an integrated analog front end and data-framing device for a 13.56-MHz RFID reader/writer system. Built-in programming options make it suitable for a wide range of applications for proximity and vicinity identification systems. The reader is configured by selecting the desired protocol in the control registers. Direct access to all control registers allows fine tuning of various reader parameters as needed. Comprehensive documentation, reference designs, evaluation modules, and TI microcontrollers (based on MSP430 ™ or ARM™ technology) source code are available. The TRF7960A is a high-performance 13.56-MHz HF RFID reader IC comprising an integrated analog front end (AFE) and a built-in data framing engine for ISO15693, ISO14443A/B, and FeliCa. It supports data rates up to 848 kbps for ISO14443 with all framing and synchronization tasks on board (in ISO Mode, default). The TRF7960A also supports NFC Forum Tag Types 1, 2, 3, and 4 operations (as reader/writer only). This architecture enables the customer to build a complete and cost-effective yet high-performance multiprotocol HF RFID/NFC reader/writer using a low-cost microcontroller (for example, an MSP430). Other standards and even custom protocols can be implemented by using two of the Direct Modes the device offers. These Direct Modes (0 and 1) allow the user to fully control the analog front end (AFE) and also gain access to the raw subcarrier data or the unframed, but already ISO formatted data and the associated (extracted) clock signal. 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 MSP430 is a trademark of Texas Instruments. 3 ARM is a trademark of ARM Limited.
