Description
General part information
ST25R3912 Series
The ST25R3912 is a highly integrated NFC initiator / HF reader IC, including the analog front end (AFE) and a highly integrated data framing system for ISO 18092 (NFCIP-1) initiator, ISO 18092 (NFCIP-1) active target, ISO 14443A and B reader (including high bit rates), ISO 15693 reader and FeliCa™ reader. Implementation of other standard and custom protocols like MIFARE™ Classic is possible using the AFE and implementing framing in the external microcontroller (Stream and Transparent modes).
The ST25R3912 is positioned perfectly for the infrastructure side of the NFC system, where users need optimal RF performance and flexibility combined with low power.
The device is optimized for applications with directly driven antennas. The ST25R3912 is alone in the domain of HF reader ICs as it contains two differential low impedance (1 Ohm) antenna drivers.
