NFC interface chip
The AS3953 NFiC™ enables all applications to interact with an NFC mobile phone in an instant. It is a fast NFC to SPI interface capable of harvesting field energy up to 5mA.
- Direct NFC to SPI interface (up to type 4)
- 5mA Energy harvest
- 106 to 848kbps data transfer rate
- Built in 1kbit high endurance EEPROM (>1Mu write cycles)
The device is ideal for applications like Passive wake-up, Multipurpose HF interface to a controller, Low power or passive programming, Ultra Low Power Data Logger, RFID Programmable configuration EEPROM, ISO 14443A smart card, NFC Forum Tag Type 4, and Bluetooth and Wi-Fi pairing.
