Description

AS3955 NFC Interface Tag NFC T2T to SPI/I2C Interface Tag IC Features High sensitivity ISO14443A frontend Tunneling and extended modes for high-speed bidirectional data transfer Fully compliant to NFC Forum T2T standalone, T4T with ext. microcontroller & ISO 14443A Energy harvesting up to 5mA@4.5V Benefits Standalone NFC passive tag functionality High endurance EEPROM memory reaches automotive grade quality Allows batteryless designs Fast system integration and high-speed data transfer Product parameters Frequency [MHz]: 13.56 Protocol: NFC Forum compliance and ISO 14443A compliance Supply Voltage [V]: RF field or ext. 1.65 to 5.5 Temperature Range [°C]: -40 to +125 Interface: ISO14443A \ SPI slave interface up to 5 Mbit/s \ I²C slave interface up to 1 Mbit/s EEPROM [kbit]: 4 Features: Type 2 Tag \ Type 4 Tag emulation \ Passive wake-up interrupt \ 32-bit password memory protection \ Silent mode \ Energy harvesting 5mA @ 4.5V Data Rate [kbit/s]: 106 Package: Die, MLPD-10, WL-CSP General Description AS3955 NFC dynamic tag IC is the ultimate solution to easily add NFC functionality to electronic devices, pair them with NFC phones and transfer data. Thanks to a high sensitivity ISO14443A front-end and integrated resonance capacitor, AS3955 offers standalone NFC passive tag functionality in a small footprint. Fast system integration and high speed data transfer are guaranteed by the available SPI and I²C interfaces and by optimized protocols (tunneling mode and extended mode), allowing bidirectional communication between the device microcontroller and an external NFC compliant device or ISO14443A reader device.
