The STMicroelectronics NFC reader is a high-performance universal device designed for NFC charging, payment, and consumer applications. It supports NFC initiator, NFC target, NFC reader, and NFC card emulation modes. Compliant with EMVCo 3.1a analog and digital standards, it is optimized for demanding POS Terminal applications, ensuring fast EMVCo certification cycles even in harsh conditions with antennas placed behind noisy LCD displays. Featuring high RF power with dynamic power output, it efficiently drives antennas and enables large interaction distances, even with small antennas used in access control and EMVCo readers. It also offers long-range and low-power card detection by measuring I and Q channels to analyze the amplitude and phase of the antenna signal.

Low power inductive card detection

I/Q demodulator with baseband channel summation

Dynamic power output Field strength is controlled to stay within given limits it is a software feature

Active wave shaping Over and undershoots are reduced

Noise suppression receiver Reception is allowed in a noisy environment

External communication interfaces

Serial peripheral Interface up to 10 Mbit/s

Possibility to drive one differential or two independent single-ended antennas
