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. The AS3953B is used with an appropriate antenna coil connected to the terminals LC1 and LC2, and behaves as a normal passive ISO 144443A tag PICC . After the anti-collision protocol is passed, the PCD sends a Wake-Up command, which wakes up the microcontroller by sending an interrupt. From this point onwards, the AS3953B serves as a data link between the microcontroller and the PCD. AS3953B can also operate as NFCIP-1 target at 106kbit/s. The AS3953B includes an onboard EEPROM that can be accessed either from the PCD or from the microcontroller via the SPI interface. This built-in flexibility makes it ideal for two types of applications: • Where personalization data is programmed by the PCD even in case the SPI side is not powered and it is later read by microcontroller through SPI interface. • Where log data is stored periodically by the microcontroller and can then be read by the PCD even when the microcontroller is not powered. A regulated power supply voltage extracted from the PCD field is also available on a pin and can be used as power supply for external circuitry. For example, an external microcontroller and a sensor could be powered from the PCD field combined with pass through data rates up to 848kbit/s, which means the AS3953B is ideal for contactless passive programming of MCU systems. The AS3953B can also operate as a stand-alone ISO 14443A tag. The AS3953B supports ISO 14443A up to Level-4, meaning a contactless smart card or an NFC forum compatible tag Type 4 can be built. Having a NFC Forum compatible tag interface allows the AS3953B to be used in an application where a standard NFC enabled phone is used as a PCD.
