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 can detect 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.Read more
