1.3 Description  
The TRF7960 and TRF7961 devices are integrated analog front end and data-framing systems for a  
13.56-MHz RFID reader system that supports multiple protocols including ISO/IEC 14443 A and B,  
FeliCa™, and ISO/IEC 15693. 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.  
The device supports data rates up to 848 kbps with all framing and synchronization tasks for the ISO  
protocols onboard. Other standards and even custom protocols can be implemented by using one of the  
direct modes that the device offers. These direct modes let the application fully control the AFE and also  
gain access to the raw subcarrier data or the unframed, but already ISO-formatted, data and the  
associated (extracted) clock signal.  
The receiver system has a dual-input receiver architecture to maximize communication robustness. The  
receivers also include various automatic and manual gain control options. The received signal strength  
from transponders, ambient sources, or internal levels is available in the RSSI register.  
A SPI or parallel interface can be used for the communication between the MCU and the TRF796x reader.  
When the built-in hardware encoders and decoders are used, transmit and receive functions use a 12-byte  
FIFO register. For direct transmit or receive functions, the encoders or decoders can be bypassed so the  
MCU can process the data in real time.
