Product Overview
ST25R3914-AQWT is an automotive high performance HF reader / NFC initiator with 1W output power supporting AAT for automotive applications, AEC-Q100 grade 1 qualified, including the analogue 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). It is positioned perfectly for the infrastructure side of the NFC system, where users need optimal RF performance and flexibility combined with low power.
- Wide supply voltage range from 2.4 to 5.5V
- Support HBR up to 848 kbit/s PICC to PCD and PCD to PICC framing
- Capacitive sensing - Wake-up
- Automatic antenna tuning system providing tuning of antenna LC tank
- Automotive high performance HF reader / NFC initiator supporting AAT
- Automatic modulation index adjustment
- AM and PM demodulator channels with automatic selection
- User selectable and automatic gain control and 6Mbit/s SPI with 96bytes FIFO
- 32-pin VFQFPN (5 mm x 5 mm) with wettable flanks
- Temperature range from -40°C to 125°C
