FM24NC32Tx
FM24NC32Tx is a 32Kbit dual interface EEPROM with flexible tag function. The 32kbit data memory and the dedicated tag memory can be accessed by both two wire serial interface and ISO/IEC 14443A compatible RF interface. When accessed by RF interface, the device is fully compatible with NFC Forum Type 2 tag. The device can also access tag memory through the conventional address by two wire serial interface. This feature ensures a flexible NFC tag application.
