FM25NQ04Tx
FM25NQ04Tx is a 4Mbit dual interface Flash with flexible tag function. The 4Mbit data memory and the dedicated tag memory can be accessed by both SPI interface and ISO/IEC 14443A compatible RF interface. When tag memory 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 SPI interface. This feature ensures a flexible NFC tag application.
