Product Overview
ST25R3917 is high performance NFC universal device supporting NFC initiator, NFC target, NFC reader and NFC card emulation modes when applicable. Being fully compliant with EMVCo 3.0 analogue and digital, this NFC IC is optimized for POS terminal applications and enables the fastest EMVCo 3.0 certification cycles possible, even under harsh conditions with antenna around noisy LCD displays. The ST25R3917 offers a reduced feature set. The also features high RF output power to directly drive antennas at high efficiency. Includes additional features, making 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 be detected by performing a measurement of the amplitude or phase of the antenna signal. Suitable for a wide range of NFC and HF RFID applications.
- Operating modes (reader/writer, card emulation, active and passive peer to peer)
- Dynamic power output (DPO) controls the field strength to stay within given limits
- Active wave shaping (AWS) reduces over and under-shoots
- Noise suppression receiver (NSR) allows reception in noisy environment
- Automatic antenna tuning (AAT) via variable capacitor
- Integrated EMVCo 3.0 compliant EMD handling
- External communication interfaces
- Wide peripheral communication supply range from 1.65 to 5.5V
- Wide supply voltage, ambient temperature range (2.6-5.5V from -40-105°C, 2.4-5.5V from -20-105°C)
- ISO/IEC 14443 Type-A and Type-B, ISO/IEC 15693, FeliCa™, ISO/IEC 18092 passive initiator mode
