As a leading screen printing manufacturer we consider joining an organization like SECAP an important step towards demonstrating our expertise and the ways in which we can assist manufacturers to overcome these issues,” said Joachim Kloeser, chief technology officer for EKRA, in a statement.

Der Chip ist als 128 MBit x 8 organisiert und arbeitet bei Spannungen zwischen 2,7 bis 3,6 V. Die Zeit für den ersten Zugriff gibt der Hersteller mit 50 Mikrosekunden an, für serielle Zugriffe mit 50 Nanosekunden.

National Semiconductor Corp. today is unveiling seven programmable power and lighting management ICs to enable battery efficiency in wireless feature” phones.

Designed as complete subsystems, the semiconductors integrate building blocks for voice and multimedia modems in portable devices, and provide a full spectrum of add-on display and lighting functions for color displays and handsets, the company said.

Most of these devices were developed along with our lead customers to introduce features that allow mobile phones to be more attractive to end users,” said John Guyatt, marketing manager for mixed-signal, analog, and power ASICs at National Semiconductor in Berkshire, England.

We have used the strength of our standard product circuit design and brought it into play with more integrated devices and packaging solutions,” Guyatt said.

Initially all the products will be offered in compact leadless lead-frame and laminate chip-scale packages (CSPs). In the third quarter of 2003, National, which is headquartered in Santa Clara, Calif., plans to offer them in Microfil packaging, a new technology that will reduce the footprint from 49mm2 to 16mm2, Guyatt said.

The LP3935, 3938, 3941, 3945, and 3946 are programmable analog power management ICs that integrate independent and programmable lithium-ion and nickel/metal hydride battery charging functions, from seven to 11 high-efficiency linear regulators, system start-up and control with serial interfaces, and one or more LED display drivers.

They are priced from 90 cents to $2.25, depending on features, in quantities of 500,000, the company said.

The programmable lighting management systems, LP3933 and LP3936, address features that make cellular handsets fashionable, such as fun lighting”–the use of blinking lights to represent different ring tones.

Weber, 39, said he gets by on four to six hours of sleep. He has dinner three times a week with his family, which includes two children, ages 4 and 6, and finds time for his hobby: building design. Weber got started by working on set design for Harvard drama productions. He has since branched out to bigger structures, including a garage-cum-poolhouse co-designed with a local architect.

There may be an analogy between his co-design at home and the upcoming competition between the Opteron X86 instruction set and Intel's newly created Epic instruction set for its 64-bit processor. For that fight, Weber also draws on lessons learned at Kendall Square Research.

Some like to start with a clean sheet of paper,” Weber said. Intel sees itself needing to lead by starting with a blank sheet for Epic.

At AMD, we see the advantages in being compatible with the software that's out there. Our history is that we can't change everything.”
