Features

NAC1080 is an IC, suitable and optimized for NFC communication controlled actuation. It contains a NFC

transceiver, an actuation interface, a microcontroller and wired communication interfaces. NAC1080 is available

in a 16-pin package. NAC1081 is available in a 32-pin package. The functional pins in both package variants are

identical.

The chip can operate in two different power supply modes:

? active supply mode:

- The chip is supplied by an external 3V power supply source (e.g. battery).

? passive supply mode:

- The chip is harvesting energy from the external NFC RF field. No additional external supply source is

required. Of course, operation of the chip requires the presence of the NFC field in this use case. The

chip can charge external capacitors, in order to store harvested energy. External storing capacitors can

be used to store the required amount of energy to initiate an actuation action (e.g. to drive a motor).
