NFC – NTAG

22

What is NFC?

• Short-range (<10 cm), 13.56MHz secure

contactless technology

• Reader/Writer, Card Emulation, Peer to Peer

modes possible in same device

• Standardized in ISO18092

• Compatible with existing ISO14443,

ISO15693 contactless cards & reader

infrastructure

• Data exchange rate up to 848kbit/sec

NTAG21xF Field Detection Circuit

• For low power applications, the Field Detect may trigger a Power Management unit

• FD goes Low when the field is detected; PMU receives interrupt, switches on VCC for

µC

• Alternatively, FD can (through a driver) may be connected to INT pin of µC
