STMicroelectronics CLOUD-ST25TA02KB Demonstration Board

STMicroelectronics CLOUD-ST25TA02KB NFC Forum Type 4 Tag IC Demonstration Board is designed for the ST25TA02KB-P device. The STMicroelectronics ST25TA02KB-P NFC/RFID tag IC with a digital General Purpose Output (GPO) supports NDEF tag applications for NFC Forum Type 4.

The CLOUD-ST25TA02KB uses the ISO/IEC 14443 Type A protocol for communication and is fully powered by the RF field. An external reference voltage is required when the GPO output is used 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.

When asserted, the GPO signal is active High and can be used as a rising edge interrupt. The GPO signal may be configured through the RF interface for various uses, including indicating Field Detection (by default) to wake up an MCU or to host a BLUETOOTH® or a Wi-Fi® chipset.
