Product overview
Description
Delivering high-end performance in a small 4 x 4 mm package, the ST25R200 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 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 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 device, supported by ST’s noise suppression receiver (NSR) technology, allows successful reads even in noisy environments.
It includes an advanced analog front-end (AFE) and a highly integrated data framing system for NFC‑A/B (ISO14443A/B) and NFC‑V (ISO15693) to read cards. The transparent mode of the AFE can be used to implement other custom protocols in reader mode.
The device comes in a compact 4 x 4 mm 24-pin TQFN package, allowing the integration of NFC technology in small devices.
Is 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 -40 °C up to +85 °C.
