Product overview
Description
The CLOUD-ST25TA02KB is a ready-to-use demonstration board intended to evaluate the ST25TA02KB-P device.
The ST25TA02KB-P is a dynamic NFC/RFID tag IC with a digital General Purpose Output (GPO), embedding a 2 Kbit EEPROM that supports NDEF tag applications for NFC Forum Type 4.
The device communicates using the ISO/IEC 14443 Type A protocol, and is fully powered by the RF field. When the GPO output is used, an external reference voltage is required to set the high level voltage of the GPO signal to be directly compatible with the I/O voltage of the MCU or Host, without the need for any level shifter.
The GPO signal is active High when asserted, and can be used as a rising edge interrupt. It may be configured through the RF interface for various uses, like indicating Field Detection (by default) to wake-up an MCU, or Host like a Bluetooth® or a Wi-Fi® chipset.
