31 WiGig * System Implementation WiGig Active Antenna Design Objectives: - WiGig* is a key component of No wires strategy provides wireless expandability - When user comes to the office, he places his system on the desk - display and peripherals are wirelessly connected to the system System design - WiGig includes: M.2 controller and active antenna - Active antenna needs to be placed to allow operation while the notebook is open or closed - In this design the WiGig active antenna is placed under the camera module - Ensure that when the system is closed the base does have metal free window to allow for antenna propagation - Test for radio to radio interference and regulatory compliance WiGig docking station 31

32 E-Ink Secondary Display E-Ink (e-reader) display Express myself custom graphics on the lid Display of critical information E-reader Many more No power consumption except when the image is changing 32

33 Integration of Secondary E-Ink Display Implementation E-Ink is connected to main SOC over USB 2 interface and GPIO signals (touch) Supports touch interface to allow graphics changes, book page changes and games Adds cost and system thickness but also provides opportunity for differentiation The display will stay on until next image is downloaded Key use cases: - Custom graphics electronic sticker, favorite team, activity,. - E-Reader - Alert messages - Games - Debug messages - Advertisements - Key information when the system is brand new and shipped to the user 33

35 35 Thermal Design Considerations

36 Thermal Considerations System design objectives: - Support both fanless and fanned operation - Design system to run with fan off for most of the time - Turn on fan only when workload requires additional performance - Provide an option to trade system performance vs. fan operation Tablet implementation - Display and main components in close proximity - Location of the SoC and other components generating heat must be optimized - Options to implement fan or fanless designs - Vents must be included in the chassis - Special thermal considerations due to system shielding Base - Fanless operation for the base - Power charger, USB HUB, EC, Audio codec and wireless charging are key components 36

Circumstances will vary. Intel does not guarantee any costs or cost reduction. This document contains information on products, services and/or processes in development. All information provided here is subject to change without notice. Contact your Intel representative to obtain the latest forecast, schedule, specifications and roadmaps. Statements in this document that refer to Intel s plans and expectations for the quarter, the year, and the future, are forward-looking statements that involve a number of risks and uncertainties. A detailed discussion of the factors that could affect Intel s results and plans is included in Intel s SEC filings, including the annual report on Form 10-K.

51 Risk Factors The above statements and any others in this document that refer to plans and expectations for the first quarter, the year and the future are forwardlooking statements that involve a number of risks and uncertainties. Words such as "anticipates," "expects," "intends," "plans," "believes," "seeks," "estimates," "may," "will," "should" and their variations identify forward-looking statements. Statements that refer to or are based on projections, uncertain events or assumptions also identify forward-looking statements. Many factors could affect Intel's actual results, and variances from Intel's current expectations regarding such factors could cause actual results to differ materially from those expressed in these forward-looking statements. Intel presently considers the following to be important factors that could cause actual results to differ materially from the company's expectations. Demand for Intel s products is highly variable and could differ from expectations due to factors including changes in the business and economic conditions; consumer confidence or income levels; customer acceptance of Intel s and competitors products; competitive and pricing pressures, including actions taken by competitors; supply constraints and other disruptions affecting customers; changes in customer order patterns including order cancellations; and changes in the level of inventory at customers. Intel s gross margin percentage could vary significantly from expectations based on capacity utilization; variations in inventory valuation, including variations related to the timing of qualifying products for sale; changes in revenue levels; segment product mix; the timing and execution of the manufacturing ramp and associated costs; excess or obsolete inventory; changes in unit costs; defects or disruptions in the supply of materials or resources; and product manufacturing quality/yields. Variations in gross margin may also be caused by the timing of Intel product introductions and related expenses, including marketing expenses, and Intel s ability to respond quickly to technological developments and to introduce new features into existing products, which may result in restructuring and asset impairment charges. Intel's results could be affected by adverse economic, social, political and physical/infrastructure conditions in countries where Intel, its customers or its suppliers operate, including military conflict and other security risks, natural disasters, infrastructure disruptions, health concerns and fluctuations in currency exchange rates. Results may also be affected by the formal or informal imposition by countries of new or revised export and/or import and doing-business regulations, which could be changed without prior notice. Intel operates in highly competitive industries and its operations have high costs that are either fixed or difficult to reduce in the short term. The amount, timing and execution of Intel s stock repurchase program and dividend program could be affected by changes in Intel s priorities for the use of cash, such as operational spending, capital spending, acquisitions, and as a result of changes to Intel s cash flows and changes in tax laws. Product defects or errata (deviations from published specifications) may adversely impact our expenses, revenues and reputation. Intel s results could be affected by litigation or regulatory matters involving intellectual property, stockholder, consumer, antitrust, disclosure and other issues. An unfavorable ruling could include monetary damages or an injunction prohibiting Intel from manufacturing or selling one or more products, precluding particular business practices, impacting Intel s ability to design its products, or requiring other remedies such as compulsory licensing of intellectual property. Intel s results may be affected by the timing of closing of acquisitions, divestitures and other significant transactions. A detailed discussion of these and other factors that could affect Intel s results is included in Intel s SEC filings, including the company s most recent reports on Form 10-Q, Form 10-K and earnings release. 51 Rev. 1/15/15
