Editor's View -- Exclusive to Electronic Design UPDATE ********************** Digging Out The Story -- One Case History By Don Tuite, Analog/Power Editor Sometimes it takes a little digging to pull a story out of a new product announcement. What's rewarding is when that digging turns up a story that illustrates how the design process actually works. Here's an example. A week ago, Linear Technology revealed its LTC3783. According to the press materials, it's a "current-mode multi-topology converter with constant-current PWM and dimming for driving high-power LED strings and clusters." It could be used "as a boost, buck, buck-boost, SEPIC, or flyback converter, and as a constant-current/constant-voltage regulator..."

It concentrates on the common characteristics of all ADCs and what they imply for the system-level designer. The second chapter is now available. Download the first two chapters today! http://news.electronicdesign.com/t?ctl=1975B:484C79 **************************************************************** ********************** 2. Focus On Embedded ********************** ***8-Bit Development Tools Keep It Simple The latest iteration of the CodeWarrior Development Studio for HC(S)08 microcontrollers stresses efficiency and economy for programmers and designers. Version 5.0 of the package is the first of several Freescale Fast Track 8-bit development tools and resources planned for this year. With more than 100 example projects to help programmers get started, the Fast Track CodeWarrior software tools emphasize usability and allow developers to create a working project in as few as seven mouse clicks. The tools include ANSI C/C++ and compact C++ compilers that have more than 60 advanced optimization strategies specifically designed to boost performance and reduce code size for the HC(S)08 architecture. The C compilers' high level of functionality is easily accessible to first-time users, featuring an enhanced Windows-driven graphical user interface (GUI). Animated tutorials also are included to help shorten the learning curve. The development package is available now via download from Freescale's Web site. The Special Edition, with a limited 16k C compiler, is free of charge. The Standard Edition costs $2394, and the Professional Edition has a price tag of $4794.

News -- From The Editors ********************** ***Ultra-Thin VGA Camera Module Holds Down Handset Sizes At just 6 by 6 by 4.1 mm, an ultra-thin VGA camera module is ticketed for the next generation of slim camera phones. At the heart of the module is the OV7670 CameraChip, a CMOS image sensor that's just one-sixth of an inch square with a 3.6-micron pixel size. Thanks to the sensor's small size, the module's designers moved to a dual plastic-lens design, where competing modules use three lenses. Additionally, the OV7670 allows a reduction in the distance between sensor and lens, lowering the module height even further without losing image quality or camera performance. In addition to addressing the demand for smaller, thinner camera phones, the ultra-thin module may find applications in notebook PCs, where the camera module must be no thicker than the LCD housing. The ultra-slim module is now available in sample quantities. Contact OmniVision directly for pricing information.

Allen has launched www.PDPplanet.com. This Web site serves as a resource for computer history buffs interested in the DEC and XKL systems of bygone days. Through the site, registered users can Telnet into a working DECsystem-10 or an XKL Toad-1, create or upload programs, and run them, thereby stepping back into time to access an "antique" mainframe system. By demonstrating what computing environments looked and felt like some 30 to 40 years ago, PDP Planet will give users a hands-on appreciation of what it was like to be a pioneering programmer. The site provides a look at Allen's personal collection of systems from the late 1960s to the mid-1990s, which preserves the significant software created on these early machines.

The IC automatically adjusts for voltage sags and reduces the charge current as other functions on the host device consume more power. The compact IC integrates a charging device, reverse blocking diode, and current-sensing circuit in a 3- by 3-mm TDFN package. It also offers a number of safety features, including the ability to monitor battery temperature and charge state for fault conditions. Covering a 4- to 5.5-V input range, the device is designed to regulate voltage and current for 4.2-V lithium-ion/polymer battery cells. Pricing is $1.09 each in 1000-piece quantities. The IC is available now.
