But choosing the best memory for your next design can be a confusing, time-consuming proposition if you don't know how to sort through all of the options and understand which memory best suits your application. Join Samsung Semiconductor Inc. and Electronic Design's Editor-at-Large Dave Bursky for this one-hour webcast that will help you cut through the confusion to choose the optimal memory solution.

News Focus ********************** Integrated Control Cuts Size And Power In Cell Phones By integrating the power-control circuits, the MMM6035 power amplifier (PA) eliminates the need for directional couplers and detector diodes in dual-, tri-, and quad-band GSM/GPRS cell phones. This two-die module from Freescale Semiconductor provides more than 45-dB dynamic range with analog input voltage. The MMM6035 covers the 850- and 900-MHz low bands and the 1800- and 1900-MHz high bands. It has standard 50-ohm I/O impedance. The required 3-dBm input power produces an output of 34.2 dBm in the low bands and 31.5 dBm in the high bands. The power-added efficiency (PAE) is 51% to 53% in the low bands and 43% to 45% in the high bands. The chip handles Class 12 GPRS operating mode (50% duty cycle), and dc power is 3 to 4.5 V. The MMM6015 is similar. In addition to the gallium-arsenide PA and power-control circuitry, it includes integrated IPD low-pass filters and complete antenna switching. These features effectively eliminate the need for most external surface-mount discretes from most designs. The pc-board space needed for these functions can be reduced by as much as 40%. Such full integration reduces manufacturing complexity and shortens design time, which is so critical in cell designs today. The PA's antisaturation technology prevents switching transients when the battery voltage sags from a low battery. Low-band current limiting prevents battery collapse under extreme conditions. Both features enhance available handset battery life. The output on the low bands is 33 dBm with 43% PAE. The output on the high bands is 30 dBm with 35% PAE. A built-in current limiter prevents high current under excessive voltage standing-wave ratio. The MMM6035 comes in a 6- by 6- by 1-mm package, while the MMM6015 is housed in a 6- by 8- by 1.2-mm package. Samples of both are available now. Full production is expected this quarter. The MMM6035 costs $2.50 while the MMM6015 costs $4.50, both in quantities of 10,000 units.

News -- From The Editors ********************** ***DC-DC Controller Sheds Transformers The LT3782 step-up dc-dc controller features 96% efficiency and two-phase operation to deliver high output power. It uses only two inductors, eliminating the need for power and current-sense transformers. Also, it can regulate a 50-V output at 4-A load current from input sources ranging from 10 to 36 V. The two-phase operation minimizes input and output ripple currents, and it reduces the value requirements of both the input and output capacitors. With 10-V gate drive and 4-A peak drive current, the LT3782 can drive industrial-grade high-power MOSFETs at high efficiency. Using adjustable slope compensation, time delay, and undervoltage lockout, as well as synchronous operation and clock synchronization, power-supply designers can tailor the circuit to achieve optimum performance. The LT3782 is offered in a thermally enhanced 28-lead SSOP. It's rated for –40 deg. C to 125 deg. C operation. Pricing in 1000-piece lots is $4.70 each. Linear Technology Corp. ==> http://nls.planetee.com/t?ctl=75AE:1001CD ***Memory, Wireless Lead The Pack In 2004 In 2004, semiconductor suppliers offering memory and wireless devices outperformed firms focused on other products, according to the final annual semiconductor rankings from iSuppli Corp. Semiconductor suppliers that derive much of their revenue from sales of memory chips, such as Samsung and Infineon, expanded their revenue by rates ranging from 29.1% to 58% last year. Other semiconductor suppliers, including Texas Instruments and Freescale Semiconductor, received major boosts in revenue due to their participation in the wireless market. Wireless represented the fastest-growing application market for semiconductors in 2004, with revenues growing by 31.2% for the year. Worldwide semiconductor revenue growth in 2004 was 24%, compared to 14.9% in 2003. With revenue growth expected to slow to 6.1%, iSuppli predicts that chip suppliers will have a tougher time in 2005. iSuppli Corp. ==> http://nls.planetee.com/t?ctl=75AD:1001CD ***Low-Power Image Sensor Also Processes Pix A camera system-on-a-chip (SoC) combines image sensing and processing. It also can enhance images at low light levels. To achieve the latter, Micron Technology’s 2-Mpixel MT9D111 uses the company's DigitalClarity technology. The sensor captures 15 frames/s when it's running at full 1600- by 1200-pixel resolution. In reduced-resolution mode (800 by 600 pixels), this low-power sensor SoC runs at 30 frames/s and draws less than 150 mW. Integrated in the chip is Micron's advanced 2-Mpixel sensor core with a sophisticated image flow processor. It also packs real-time JPEG compression, a 10-bit on-chip analog-to-digital converter, and advanced color interpolation for truer colors and sharper details. The integrated auto focus and JPEG compression save design costs and space typically incurred by a required companion chip. In lots of 10,000, the MT9D111 costs about $9.

TechView Scope ********************** Biometrics Ensure Document Security At Busy Printers Sharing a printer in a big office can be difficult when you're responsible for confidential documents. Whether it's government work, proprietary information, financial data, or even human resources material, that printout will be available to anyone who strolls by the printer—unless the printer uses the SecurePrint system, that is. Designed by Silex Technology America, SecurePrint includes the FUS-200N fingerprint reader with USB interface, the SX-5000U2 four-port USB device-to-device server, and SX-SecurePrint Software. The reader is connected to the printer. The software is installed on the necessary computers in the office. Users enroll their fingerprints in the system. The software's algorithm creates a unique pattern of data points for each fingerprint. When users want to print documents, the printer will hold those documents until the users enter their fingerprint on the reader. For an extra level of security, additional readers can be installed at the individual computers. Users would touch the reader before sending the document to the printer and then touch the printer's reader to release the document for printing. The system was designed to help businesses and other workplaces comply with the Health Insurance Portability and Accountability Act and Sarbanes-Oxley Act, which regulate privacy and security. During December's Government Solution Summit in Bonita Springs, Fla., attending system integrators nominated the package for the Best Government Solution Award.
