NFC interface chip offers energy harvesting 22nd May 2015

ams has launched the AS3955, an NFC interface Chip (NFiC), which offers energy harvesting and data transfer capabilities. Like its predecessor the AS3953, the AS3955 provides a contactless bridge between an NFC reader and any MCU. However, the AS3955 can also act as a power supply for the host device, harvesting as much as 5mA at 4.5V (enough to charge a Li-ion cell battery) from the RF energy radiated by an NFC reader.
