General Description ams Datasheet [v1-04] 2016-Jan-07 AS3953B 14443 High Speed Passive Tag Interface The AS3953B NFC interface IC (NFiC) delivers low cost, ultra low power NFC forum functionality to multiple different applications. The AS3953B is a analog front-end with integrated 14443A data framing and SPI interface. It is designed to create a fast data link between an ISO 14443A reader device (PCD) and a microcontroller. The AS3953B is passively powered meaning that it can be supplied from the PCD magnetic field, eliminating the need of a continual external supply. This makes the AS3953B perfect for wireless communication to a low-power battery powered device.
