The ST25TN512 NFC Forum Type 2 tag-ICs offer a new combination of cost and performance in high-volume applications like consumer engagement, product information, brand protection, and product information.
The ST25TN512/01K NFC Tag ICs are suitable for smart-city applications. They support multiple privacy and user-protection mechanisms, including a unique 7-byte chip-identifier code and TruST25 digital signature. NFC Forum T2T permanent lock blocks at block level and a configurable kill mode, which permanently disables the tag.
The ST25TN512 & ST25TN01K are certified to NFC Forum Type 2 specifications. They leverage ISO 14443 standards. These devices can be used with NFC compatible mobiles or a dedicated short range reader. The embedded device memory can store up to 208 bytes (1664 bit) of user content.
Support for NFC Data Exchange Format messages (NDEF) allows triggering native actions from a smartphone, without the need to use a dedicated app such as launching a browser or pairing Bluetooth(r). Augmented NFC Data Exchange Format (ANDEF), which allows dynamic information to be read, such as custom messages or unique tap codes, without the need for an app.
The ST’s ST25TN512/01K RF tag ICs are made using a best-in-class in-house manufacturing process. They have a 50pF internal tuning capacitance, which is widely used and allows for easy integration by inlay makers. The tags are powered by the 13.56MHz radio transmitter field, so they only require an antenna. Additional benefits include a wide operating-temperature range of -40degC to +85degC and long data retention. The ICs are available in either a sawn-and-bumped wafer format or in a DFN5 package.
The ST25TN512K and ST25TN01K can be ordered in quantity for $0.065 each.
