STMicroelectronics is set to unveil an easy-access development platform for its M24SR dynamic NFC tags that are now entering volume production in all memory densities and package options. Accelerating the design of IoT applications, ST’s M24SR Discovery Kit contains everything engineers will need to start adding NFC connectivity to any kind of electrical device, from fitness watches and loudspeakers to washing machines and water meters.
Expanding ST’s NFC portfolio, ST’s M24SR dynamic tags combine industry-standard serial-bus (I2C) and contactless RF (NFC Forum Tag Type 4) interfaces. The devices support the NFC data exchange format (NDEF) and 128-bit password protection. The M24SR series is available in EEPROM memory densities from 2 Kbit to 64 Kbit and three package types: SO8, TSSOP8, and UFDFPN8.
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.
The kit integrates a Dynamic NFC/RFID tag (M24SR64-Y), an STM32F1 microcontroller, a 13.56 MHz antenna, an LCD color screen, a USB connector, a JTAG connector, and a joystick for menu selection. The Premium version adds a Bluetooth module with audio outputs and a headset to demonstrate convenient Bluetooth pairing of a smartphone and an audio device with the M24SR.
In addition to the Discovery Kit, the comprehensive M24SR development ecosystem also includes antenna reference designs, application notes, e2e community, eDesignSuite, reference MCU drivers, and an NFC Android App.
