ST's SRTAG ICs provide an NFC Forum Type 4 tag RF interface and built-in NDEF (NFC Data Exchange Format) message support. The embedded EEPROM memory ranges from 512 bits to 64 kilobits, making it suitable for various applications such as content-rich virtual business cards and smart signage. The SRTAG series delivers state-of-the-art RF performance and features user-programmable digital CMOS output, eliminating the need for separate external components for host wake-up.

ST's new NFC tag also boasts excellent robustness, with a data retention life of 200 years (20 times the industry standard) and one million erase-write cycles (10 times the industry standard). The operating temperature range has been extended to -40°C to 85°C, allowing for convenient use with excellent performance and durability even under harsh operating conditions.

SRTAG ICs provide performance that surpasses existing solutions in terms of data protection. By combining the strongest 128-bit password protection among commercially available products with a 20-bit counter for read/write access control, the risk of tag cloning or unauthorized alteration is virtually eliminated.

Applications of SRTAG include NFC smart posters or advertisements, image processing NFC business cards, NFC tokens for automatic Bluetooth pairing, and secure access to Wi-Fi networks, as well as NFC tags for asset tracking, maintenance records, and product identification (PI).

Among the newly released products, SRTAG16K and SRTAG64K are currently in mass production, while SRTAG2KL, SRTAG2KL-P, and SRTAG512L are being supplied as sample products to major customers. The price for the 512-bit version starts at 17 cents per unit for orders of 1,000 units.
