FM11NT021TT chip has an 180bytes EEPROM memory embedded. FM11NT021TT contains the RF-Interface and the Digital Control Unit. Energy and data are transferred via an antenna, which consists of a coil with a few turns directly connected to the IN1 and IN2 of the FM11NT021TT.
FM11NT021TT has a dedicated function which is named open sense or tamper detection. A wire connects the DP pad and the GND pad when the tag is made. If this wire is open, the chip can detect this state and send this message to the reader when being checked. This function can be used in applications such as anti-counterfeit or smart packages.
