STMicroelectronics Intros NFC RFID Chips for Applications Such as Smart Signs, Bluetooth Pairing

STMicroelectronics has announced new Near Field Communication (NFC) RFID chips designed for short-range wireless connectivity in consumer electronics, computer peripherals, home appliances, industrial automation and health-care products.

The new SRTAG family of chips supports the NFC Forum's Type 4 and NFC Data Exchange Format (NDEF) standards. The SRTAG series offers embedded EEPROM memory ranging from 512 bits to 64 kilobits, which STMicroelectronics says covers a spectrum of applications including NFC smart posters and advertising, image-enhanced NFC business cards, NFC tokens for automated Bluetooth pairing and secure access to Wi-Fi networks, as well as NFC tags for asset tracking, maintenance records, and product identification.

The SRTAG series features a user-programmable digital CMOS output that eliminates the need for an external component to trigger the host wake-up. The tags also feature data retention capability of 200 years (20 times higher than the industry standard, according to the company) and 1 million erase-write cycles (10 times higher than the industry standard, STMicroelectronics reports). In addition, the SRTAG series offers an extended temperature range from -40 degrees to +85 degrees Celsius (-40 degrees to +185 degrees Fahrenheit) and couples 128-bit password protection with a 20-bit counter for read-write access control that, according to STMicroelectronics, virtually eliminates any risk of tag cloning or tampering.

The SRTAG16K, with 16 kilobits of memory, and SRTAG64K, with 64 kilobits of memory, are both available in production volumes, while the SRTAG2KL, SRTAG2KL-P and SRTAG512L models are currently sampling to lead customers. Prices for orders of 1,000 pieces start at $0.17 apiece for the 512-bit version.
