STMicroelectronics RFID, RF Access, Monitoring ICs CRX14-MQP/1GE

The CRX14-MQP/1GE is an ISO14443 type-B contactless coupler chip designed for RFID applications. It operates at a carrier frequency of 13.56 MHz and supports a data rate of 106 Kbit/s. The device features anti-collision capabilities, CRC management, and a proprietary anti-clone function from France Telecom, enhancing security in communication. This IC requires a single 5 V ¬±500 mV supply voltage and comes in a SO16 package, measuring 150 mils in width. It supports I¬=C communication through a two-wire interface, allowing for connection of up to eight CRX14 devices on the same bus, with a maximum I¬=C clock speed of 400 kHz. The chip includes a 36-byte input/output frame register and supports frame answers with or without start and end of frame indicators. Engineers considering this product should evaluate its compatibility with their RFID system requirements, particularly in terms of communication protocols and power supply specifications.
