Data sheet:
The ST25RN300 is an NCI reader / NFC controller designed for integration into NFC‑compliant products.
The device performs NFC functions in the three operating modes: card emulation, reader/writer, and peer-to-peer communication. It is based on an advanced Arm® Cortex®-M3 32‑bit microcontroller. It is designed to increase RF communication distances, ease NFC technology integration, and operate in efficient low-power modes. It is best-in-class in terms of RF output power, working up to 2.2 W. Maximum power can be safely used to communicate thanks to dynamic power control: when a card is close, power is automatically reduced to ensure interoperability and standard compliance. To complement this outstanding output power, demodulation sensitivity is improved to maximize the communication distance with all types of cards.
The card emulation mode does not require any external oscillator or reference clock source. Thanks to active load modulation and automatic adjustments based on field strength, communication distance is maximized, and interoperability is ensured. The device can operate in very low-power modes due to improved field detection sensitivity and a stable, efficient low-power card detection mechanism. It can detect the presence of a reader, card, or tag beyond its rated communication distance
The ST25RN300 exchanges data with the application processor through the NCI 2.1 (2.2 compliant) logical interface on top of the I²C connection.
