原标题:NXP PN712013.56MHz NFC解决方案

  NXP公司的PN7120是即插即用的13.56MHz NFC解决方案,支持NFCIP-1, NFCIP-2 协议,支持NCI 1.0主通信,操作环境Android或Linux,工作电压2.3 V到5.5 V,主要用在TV,STB,蓝光译码器和音频设备,家庭自动化,网关和无线路由器,家用电器,可穿戴设备,遥控,健身设备,打印机,IP电话,游戏控制台和附件.本文介绍了PN7120主要特性,框图,发送模式框图,应用电路图以及开发套件OM5577/PN7120S主要特性和PN7120 NFC控制板电路图,PCB元件布局图;BeagleBone接口板电路图,PCB元件布局图与Raspberry Pi接口板电路图,PCB元件布局图.

  PN7120, the best plug’n play full NFC solution - easy integration into any OS environment, with integrated firmware and NCI interface designed for contactless communication at 13.56 MHz.

  It is the ideal solution for rapidly integrating NFC technology in any application, especially those running O/S environment like Linux and Android, reducing Bill of Material (BOM) size and cost, thanks to:

  full NFC forum compliancy with small form factor antenna embedded NFC firmware providing all NFC protocols as pre-integrated feature direct connection to the main host or microcontroller, by I²C-bus physical and NCI protocol ultra-low power consumption in polling loop mode Highly efficient integrated power management unit (PMU) allowing direct supply from a battery PN7120 embeds a new generation RF contactless front-end supporting various transmission modes according to NFCIP-1 and NFCIP-2, ISO/IEC14443, ISO/IEC 15693, ISO/IEC 18000-3, MIFARE and FeliCa specifications. It embeds an ARM Cortex-M0 microcontroller core loaded with the integrated firmware supporting the NCI 1.0 host communication.

  The contactless front-end design brings a major performance step-up with on one hand a higher sensitivity and on the other hand the capability to work in active load modulation communication enabling the support of small antenna form factor.

  For contactless card functionality, the PN7120 can act autonomously if previously configured by the host in such a manner.

  PN7120 integrated firmware provides an easy integration and validation cycle as all the NFC real-time constraints, protocols and device discovery (polling loop) are being taken care internally. In few NCI commands, host SW can configure the PN7120 to notify for card or peer detection and start communicating with them.

  开发套件OM5577/PN7120S

  The present document describes the OM5577/PN7120S demonstration kit, a flexible and easy-to-use Single Board Computer(SBC) Kit for the PN7120 NFC Controller.

  It contains a PN7120 NFC Controller Board, a Raspberry Pi Interface Board, a BeagleBone Interface Board, as well as an NFC Forum Type 2 Tag in form of a MIFARE UL Card. It enables the development of an NFC solution based on PN7120 in a Linux or Android environment.

  PN7120 is a full NFC controller solution with integrated firmware and NCI interface designed for contactless communication at 13.56 MHz.

  This document presents first an overview of the kit.

  Then, it gives printed circuit boards details.

  Finally, it provides information for reuse of the kit in different environments.

  OM5577/PN7120S kit is a high performance fully NFC compliant expansion board for both Raspberry Pi (refer to [1] for more details) and BeagleBone (refer to [2] for more details). It meets compliance with Reader mode, P2P mode and Card emulation mode standards. The board features an integrated high performance RF antenna to insure high interoperability level with NFC devices.

  The kit is composed of 3 printed circuit boards and a MIFARE Ultralight EV1 card
