产品概述

描述

The ST25R3918 is a multipurpose NFC transceiver supporting NFC reader, passive peer to peer functionality and NFC card emulation mode.

This IC is optimized for IOT and other consumer or industrial applications where excellent analog performance is required.

The ST25R3918 is also optimized to achieve good read ranges with low output power, even under noisy and harsh environments, using noise reduction receiver technology.

This IC offers an advanced analog front end (AFE) and a highly integrated data framing system for NFC-A/B (ISO 14443A/B) reader including higher bit rates. NFC-V (ISO 15693) reader is supported up to 53 kbps via streaming mode to read cards.

ISO 18092 passive initiator and target and NFC-A / NFC-F card emulation are also available to ensure communication between end products. This enables device programming or simple NDEF data transfers to interact with Android™ phones or to use Apple® App Clips.

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

The ST25R3918 includes a low power wakeup mode to scan for the presence of a card 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 trigger the device after the configured time period and check for a presence of a tag.

The ST25R3918 is designed to operate from a wide power supply range (2.6 to 5.5 V from -40 °C to +105 °C, 2.4 to 5.5 V from -20 °C to +105 °C), and a wide peripheral IO voltage range (from 1.65 to 5.5 V).
