STMicroelectronics' ST25R3916 is a high-performance NFC universal device supporting NFC initiator, NFC target, NFC reader, and NFC card emulation modes.

The ST25R3916 includes an advanced analog front end (AFE) and a highly integrated data framing system for ISO 18092 passive and active initiator, ISO 18092 passive and active target, NFC-A/B (ISO 14443A/B) reader including higher bit rates, NFC-F (FeliCa™) reader, NFC-V (ISO 15693) reader up to 53 kbps, and NFC-A and NFC-F card emulation.

Special stream and transparent modes of the AFE and framing system can be used to implement other custom protocols such as MIFARE® classic in reader or card emulation mode.

The ST25R3916 features a high RF output power to directly drive antennas at high efficiency.

The ST25R3916 also includes several features which make it incomparable for low power applications. It contains a low power capacitive sensor to detect the presence of a card without switching on the reader field. Additionally, the presence of a card can still be detected by performing a measurement of the amplitude or phase of the antenna signal. It also contains a low power RC oscillator and wake-up timer to automatically wake-up the ST25R3916 after a selected period of time and check for a presence of a tag using one or more techniques of low power detection of card presence (capacitive, phase, or amplitude).

The ST25R3916 is designed to operate from a wide power supply range from 2.4 V to 5.5 V, and a wide peripheral IO voltage range from 1.65 V to 5.5 V.

Due to this combination of high RF output power, low power modes, and wide supply range the ST25R3916 is perfectly suited for infrastructure NFC applications.
