ST25R200 NFC/HF RFID Reader IC

Delivering high-end performance in a small 4 mm x 4 mm package, the STMicroelectronics ST25R200 multipurpose NFC reader brings the convenience of contactless interaction and features to a variety of end applications. It is especially optimized for end products in the consumer and industrial segments.

The ST25R200 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 wakeup 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.
