New NFC reader combines high performance with appealing cost

STMicroelectronics has launched the ST25R200, an NFC reader IC which provides a valuable combination of advanced features, robust communication, and affordability, making the implementation of contactless interaction in high-volume consumer and industrial products a more attractive proposition.

Combining high performance and reliability with low power consumption, the 24-pin 4 mm x 4 mm ST25R200 simplifies integration into products which require functions such as recognizing genuine accessories, ordering consumables, or monitoring device usage. High output power allows easy integration into products which have a small antenna. 

The ST25R200 supports the NFC reader/writer mode. The reader has an excellent read range, and comes with an improved low-power card detection feature, 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 such as a smartwatch or a phone when in wake-up mode.

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