M MAY CONTAIN U.S. AND INTERNATIONAL EXPORT CONTROLLED INFORMATION 8 Confidential and Proprietary – Qualcomm Atheros, Inc. 1 Introduction 1.1 Documentation overview Technical information for the QCA1990 Near Field Communication (NFC) controller system-on-chip (SoC) is primarily covered by the documents listed in Table1-1, and all of them should be studied for a thorough understanding of the device and its applications. Released QCA1990 documents are posted on the CDMATech Support Website (https://support.cdmatech.com) and are available for download. Table1-1 Primary QCA1990 documentation Document Title/description number 80-Y0597-1 QCA1990 NFC Controller SoC Device Specification (this document) Provides all QCA1990 electrical and mechanical specifications. Additional material includes pin assignments, shipping, storage, and handling instructions, printed circuit board (PCB) mounting guidelines, and part reliability. This document can be used by company purchasing departments to facilitate procurement. 80-Y0597-4 QCA1990 NFC Controller SoC Device Revision Guide Provides a history of QCA1990 device revisions. This document explains how to identify the various device revisions, and discusses known issues (or bugs) for each revision and how to work around them. 80-Y0597-5 QCA1990 NFC Controller SoC Design Guidelines/Training Slides Provides detailed descriptions of all QCA1990 functions and interfaces, including its various operating modes. Example applications are presented, and then specific design topics such layout guidelines, power distribution recommendations, external component recommendations, troubleshooting techniques, etc. are addressed. 80-Y0597-41 QCA1990 Design Example 80-Y0597-1 Rev. M MAY CONTAIN U.S. AND INTERNATIONAL EXPORT CONTROLLED INFORMATION 9 Confidential and Proprietary – Qualcomm Atheros, Inc. QCA1990 NFC Controller SoC Device Specification Introduction This QCA1990 device specification is organized as follows: Chapter1 Provides an overview of the QCA1990 documentation, gives a high-level functional description of the device, lists the device features, and defines the terms and acronyms used throughout this document. Chapter2 Defines the device pin assignments. Chapter3 Defines the device electrical performance specifications, including absolute maximum and operating conditions. Chapter4 Provides IC mechanical information, including dimensions, markings, ordering information, moisture sensitivity, and thermal characteristics. Chapter5 Discusses shipping, storage, and handling of the QCA1990 devices. Chapter6 Presents procedures and specifications for mounting the QCA1990 onto PCBs. Chapter7 Presents QCA1990 reliability data, including a definition of the qualification samples and a summary of qualification test results. 1.2 QCA1990 SoC introduction The QCA1990 device is a standalone NFC SoC with 40 nm CMOS technology. The QCA1990 device incorporates the radio, baseband, processor, and firmware necessary for short-range wireless connectivity. The NFC controller interface (NCI) protocol is implemented over the I2C interface to the host. The QCA1990 device is intended for use in data transfers between devices (peer-to-peer mode communication), to access digital content on the move (NFC reader/writer), and for mobile payment and ticketing (card emulator). Its high integration and small wafer-level nano-scale package (WLNSP) minimize the external components and the PCB area in design. Two different operating regions are supported: Region 1 Battery level is normal (above phone critical shutdown voltage). Host is powered up. Full functionality of the near field communication controller (NFCC). Region 2 Battery voltage is low, but above the NFCC is critical. Host is powered down. Card emulator only, using a secure element connected to NFC controller directly (e.g., for transit ticketing). 80-Y0597-1 Rev.
