M24SR Dynamic NFC Tag Series


STMicroelectronics' new memories make it easy to add near field communications capability to any kind of electrical device

A vast range of consumer devices, domestic appliances and industrial equipment is set to become smarter, more flexible and easier to use thanks to a new family of “dynamic NFC tag” memories from STMicroelectronics.

These NFC/RFID tag products make it easy to add Near Field Communication (NFC) capability to any kind of electrical device, from loudspeakers and printers, to cookers and washing machines, to electricity, gas and water meters. Jumpstarting the development of connected Consumer, Domestic, and Industrial equipment, the M24SR Discovery Kit illustrates NFC use cases such as “tap and pair”, URL connection, send an SMS or an email, and business-card download.

In addition to the Discovery Kit, the comprehensive M24SR development ecosystem also includes antenna reference designs, application notes, e2e community, eDesignSuite, reference MCU drivers, X-NUCLEO-NFC expansion board, and an NFC Android App.
