NFC ISO 14443 IP

 

The NFC ISO 14443 IP is  a comprehensive analog and digital IP for NFC integrated circuit cards at 13.56 MHz. The NFC ISO 14443 IP is a turnkey solution ready to connect to an antenna on one end and to a standard AMBA APB interface on the other end.

The NFC ISO 14443 IP supports Type A and Type B  as defined in the ISO/IEC 14443 specification. It is designed to be totally compliant with the ISO/IEC 14443 specification.

It is designed to minimize area and power consumption. The area for a typical 130nm implementation is  0.5 mm2. The gate count for the digital portion of the whole IP (Protocol) is just below 3000 NAND2 equivalent gate. The Power Management unit is designed to deliver up to several mW to  power the other blocks of the device.

Did you know ?

 

Near Field Communication (NFC) is a ISO/IEC standard (ISO 18092 & ISO 21481) that specifies:

  • RF interface's modulation scheme, coding, transer speed and frame format.
  • Initialization scheme and data-collision control
  • Transport layer

 

The ISO/IEC 14443 standard defines contactless smart cards operating at 13.56 MHz. NFC devices often incorporate a ISO 14443 protocol.

The operating distance between card and readers depends on several parameters such as the reader's antenna, the card's antena, the reader's power and the card's power consumption.

In the table below; you'll find examples of typical operating distances for various card's power consumption

 

 

  Card's power                Distance                   (µw)                (cm)
