RFID, RF Access, Monitoring ICs is a broad category of categories that includes such varied items as radio frequency identification, proximity tracking, and access control systems. TRF7962ARHBR is a general purpose radio frequency identification (RFID) controller IC which performs both the reader and control functions associated with RFID systems. It can be used in areas such as logistics management, security, access control, or asset tracking.

TRF7962ARHBR is a single-chip RFID reader IC that supports both 125kHz and 13.56MHz frequency range operation. Its RF data input can be powered at both low and high levels, allowing for implementations which require both low and high power RFID transceiver capabilities. It is specially designed for implementations which require NXP MIFARE contactless cards and tags as part of the solution, but it is compatible with all other ISO14443A, NFC and MIFARE communication standards. The ICs integrated advanced power management features enable customers to configure and optimize the system power consumption to extend battery life in portable RFID reader applications.

TRF7962ARHBR can be used to detect and read information from multiple RFID transmitters or tags in its field of view. A single antenna connected to its RF input pin is able to capture data emitted by up to 16 different 125kHz or 13.56MHz transceivers/tags. The information gathered by the IC’s receiver is processed to produce a readable data stream, which can then be used for various applications.

In addition to its ability to read RFID tags, TRF7962ARHBR supports MIFARE control-based authentication. The integrated MIFARE near-field communications (NFC) protocol provides an additional layer of security by allowing the reader/controller to quickly, securely, and accurately identify valid MIFARE cards and tags in its immediate vicinity.

At the core of the IC’s functionality is an 8051 microcontroller core, enabling an application-specific processing environment for customization and control. Up to 64 kbytes of program memory is supported so that the user can implement larger applications while allowing sufficient space for program code, data selection, and data protection. In addition, the IC contains a 12-bit analog-digital converter (ADC) enabling the device to capture analog data from external sensors and convert it into digital information that can be used by the controller.

TRF7962ARHBR is suitable for a wide range of security, access control, asset tracking and RFID applications. The combination of features, including low power consumption and secure communication, makes it ideal for any environment where reliable and secure wireless means of communication are needed.
