Use NFC tags for safe, convenient links to IoT, says ST

STMicroelectronics’ SRTAG NFC/RFID tags claim widest memory range, best data retention and most write-erase cycles, and the strongest data protection, opening possibilities for short-range wireless connectivity in consumer electronics, computer peripherals, home appliances, industrial automation, and healthcare products.

SRTAG ICs provide the NFC Forum Type 4 Tag RF interface and built-in NDEF (NFC Data Exchange Format) message support. The embedded EEPROM memory density spans from 512 bit to 64 kbit, covering applications including content-rich virtual business cards and smart signs. The SRTAG series delivers state-of-the-art RF performance and features a user-programmable digital CMOS output that eliminates the need for an external component to trigger the host wake-up.

These NFC tags claim higher levels of robustness, with data retention of 200 years (20 times higher than the industry standard) and 1 million erase-write cycles (10 times higher than the industry standard). Extended temperature range from -40°C to 85°C ensures performance and durability in the harshest operating conditions.

ST also asserts that SRTAGs outperform existing solutions in data protection, coupling the market’s strongest 128-bit password protection with a 20-bit counter for read/write access control that virtually eliminates any risk of tag cloning or tampering. Applications include NFC smart posters and advertising, image-enhanced NFC business cards, NFC tokens for automated Bluetooth pairing and secure access to WiFi networks, as well as NFC tags for asset tracking, maintenance records, and product identification.

Prices start at $0.17 for the 512-bit version (1000).
