NFC Forum Type 2 Tag IC with UART Interface and Energy Harvesting Function. NFC Forum Type 2 tag ICs with a UART interface, facilitating data transfer between NFC devices and UART-connected devices such as MCUs. Additionally, It can harvest energy for peripheral circuits—up to 10mA from desktop RFID readers and up to 7mA from typical NFC phones. This energy-harvesting capability enables “batteryless” applications, allowing devices to operate instantly when an NFC device is tapped, even without an internal battery
