ST25TA SERIESNFC Forum Type 4

NFC tags with ISO/IEC 14443 Type A RF interface, NDEF memory,
128-bit password protection and TruST25 digital signature
ST’s ST25TA ICs provide theNFC Forum Type 4 Tag RFinterface and built-in NDEF (NFC
Data Exchange Format) message
support. The embedded
EEPROM memory density
spans from 512 bits to 64 Kbits,
covering a wide spectrum ofapplications including contentrich virtual business cards
and smart signs. The ST25TA
series delivers state-of-the-art
RF performance and features
a user-programmable digital
CMOS (or Open Drain) outputthat eliminates the need for an
external component to trigger
the host wake-up.
