Product overview

Description

Delivering high-end performance in a small 4x4 mm package, the ST25R100 multipurpose NFC transceiver brings the convenience of contactless interaction and features to a variety of end applications. It is especially optimized for end products in consumer and industrial segments.

The ST25R100 supports NFC reader/writer mode. The high output power allows easy integration into applications with small antennas. The reader has an excellent read range and comes with an improved low power card detection (LPCD), increasing detection range in inductive wake-up mode. During this low power wake-up mode, the system is capable of detecting the approach or the removal of tags. The IC contains an RC oscillator and programmable timer to automatically scan for cards or other NFC-enabled devices like a smartwatch or a phone when in WU mode.

The high sensitivity of the ST25R100, supported by ST’s noise suppression receiver (NSR) technology, allows successful reads even in noisy environments.

The device includes an advanced analog front end (AFE) and a highly integrated data framing system for NFC-A/B (ISO 14443A/B) and NFC-V (ISO 15693) to read cards. The transparent mode of the AFE can be used to implement other custom protocols in reader mode.

The ST25R100 comes in a compact 4x4mm 24-pin TQFN package, allowing the integration of NFC technology in small devices.

The ST25R100 is designed to operate from a wide power supply range (2.7 to 5.5 V) and a wide peripheral IO voltage range (from 2.7 to 5.5 V), within a broad ambient temperature range from -25 °C up to +85 °C.
