Description:     The PIC16C62X devices create a new branch in Microchip?s PIC16CXXX 8-bit microcontroller family by incorporating two analog comparators and a variable voltage reference on-chip. The comparators feature programmable input multiplexing from device inputs and an internal voltage reference. The internal voltage reference has two ranges, each capable of 16 distinct voltage levels. Typical applications such as appliance controllers or low-power remote sensors can now be implemented using fewer external components thus reducing cost and power consumption. The 18-pin SOIC or 20-pin SSOP packages are ideal for designs having size constraints.

Microsoft demoed their upcoming Windows 8 OS during the BUILD conference today along with the sneak peek to developers platform and tools. Windows 8 includes plethora of new features which includes the all new immersive Metro style UI, Internet  Explorer 10 (IE10), Task Manager, Quick boot, Face password, Cloud integration etc. They also made available the Windows 8 Developer Preview copy to all the attendees out there along with a Samsung Tablet so that the developer community can play with it and give feedback before the RTM hits store. And for the rest of us the very same files will be uploaded to their public servers and will be available soon.

Features:
The main feature that was shown is the extensively redesigned user interface, optimized for touchscreens as well as mice and keyboards. A new "Start screen", similar to the one in Windows Phone 7, includes live application tiles. It replaces the Start menu, being triggered by the Start button or Windows key, and is also the first screen shown on startup. The user can go to the regular desktop by choosing the "Desktop" tile or a traditional desktop-based application. The Start screen also displays the user's name and avatar. Windows 8 has a new developer platform according to Microsoft Vice President Christopher Ham, who called it "our new developer platform, which is...based on HTML5 and JavaScript. The new applications run in full-screen, but two of them can be displayed side-by-side using "Snap". Examples of new applications that were demoed include a Twitter client, a weather application, a stock-tracking application, an RSS news feeder, and a virtual piano.

The new interface is primarily designed for 16:9 screen resolutions, with 1366×768 and larger screens able to display two Windows 8 applications. 1024×768 screens can display one Windows 8 application in full-screen, and 1024×600 screens can only use the traditional Windows desktop. Mike Angiulo confirmed at Computex 2011 that Windows 8 will use OEM Activation 3.0 instead of OEM Activation 2.1 (used by Windows 7), which supposedly makes it less prone to cracks. Windows 8 features a new lock screen that shows the date and time and notifications, along with a customisable background.
Windows 8 will also include Microsoft's Hyper-V virtualization tool. Previously only offered in Windows Server, Hyper-V will now be available in client versions of Windows for the first time. The system requirements for Hyper-V are a 64-bit processor, a 64-bit version of Windows 8, and a minimum of 4 GB of RAM. Hyper-V also requires a 64-bit system that has Second Level Address Translation (SLAT), a feature that helps with memory management. Many of Intel's and AMD's recent processors support this feature, including many of Intel's i-Series processors (with Extended Page Table) and AMD's 10h family processors. On September 8, 2011, Microsoft announced that Windows 8 has short boot times, because it saves the kernel's memory to the hard disk on shutdown (similar to the existing Hibernate option) and reloads it on startup.
Cofiguration Details: All configuration same as Windows 7 (32 & 64 Bit)
Download Instructions: Click on download link to start download directly from MS own server. Direct download with resumable option.

System Requirements-
Windows Developer Preview works great on the same hardware that powers Windows Vista and Windows 7
1 gigahertz (GHz) or faster 32-bit (x86) or 64-bit (x64) processor
1 gigabyte (GB) RAM (32-bit) or 2 GB RAM (64-bit)
16 GB available hard disk space (32-bit) or 20 GB (64-bit)
DirectX 9 graphics device with WDDM 1.0 or higher driver
Taking advantage of touch input requires a screen that supports multi-touch
To run Metro style Apps, you need a screen resolution of 1024 X 768 or greater.
