Analog front end for NFC

4 November 2015 Telecoms, Datacoms, Wireless, IoT Analogue, Mixed Signal, LSI

ams announced a new NFC (near field communications) solution for manufacturers of smart watches, wristbands and other space-constrained devices, enabling them to reliably support contactless payments and ticketing. The AS3921 analog front end (AFE), with ams’ boostedNFC technology, draws just 12 µA in normal operation, and provides a power-saving Secure Element wakeup function. Packaged in an ultra-compact WL-CSP measuring just 2,115 x 1,735 mm, and connecting directly to the Secure Element with few external com-ponents required, the device implements active load modulation i.e., it generates an RFID card response which is synchronous to the reader’s field.
