Op-Ed: There's a blog post over at CNET about an E85 Dodge Viper which is breaking speed records. They wrote, "More than doubling the horsepower probably had a big effect on the performance of the car, but the extra octane can't hurt. Ethanol also cuts down on the greenhouse gases from the tailpipe."
Microchip Technology Inc announced the first eight members of the PIC18F high-performance 8-bit microcontroller family. To control power consumption, the 28-, 40- and 44-pin microcontrollers provide nanoWatt Technology features that include power-managed modes, an operating voltage range of 1.8V to 3.6V and efficient on-chip peripherals. Additionally, speeds of 16 MIPS (64 MHz) can be achieved at 3V operation from the internal oscillator, offering high performance while maintaining low power consumption.
Energy News: Two interesting stories today from eWeek: first, the Green Grid member companies signed a Department of Energy agreement for data center metrics; second, coverage of Energy Star director Andrew Fanara's declaration that volume servers are so obviously bad for the green agenda.
National Semiconductor Corporation introduced two precision operational amplifiers (op amps) that offer the industry’s lowest input voltage noise and highest accuracy for products operating at low frequencies and low supply voltage, according to the company. Target applications include industrial and scientific weight scales, pressure sensors and other low ohmic sensor systems. The LMP7731 single and LMP7732 dual precision op amps provide low input voltage noise of 2.9 nV/sqrt Hz with a
On a recent flight I talked with a software-engineering manager about the challenges of finding good embedded-system developers. She told me she has a team of 12 developers, but only three had proficiency with drivers, board-support packages, and boot-loaders. The other nine -- all good application developers -- lacked low-level coding experience. I asked if she had heard of the Microsoft .NET Micro Framework.
Op-Ed: The full story isn't clear here, but it looks like a government crackdown on the very popular Alameda County Computer Recycling Center. For readers not in the Silicon Valley area, I can personally attest that ACCRC is a well-run, well-supported organization which does a valuable community service. So why would an EPA inspector
PLX Technology, Inc. introduced ExpressLane PCIe Gen 2 switches which include the PEX 8648 (48 lanes, 12 ports), PEX 8632 (32 lanes, 12 ports), PEX 8624 (24 lanes, 6 ports), PEX 8616 (16 lanes, 4 ports) and PEX 8612 (12 lanes, 3 ports). These Gen 2 switches features includw the low latency, low power, high performance, integrated non-transparent ports and Hot-Plug controllers, the smallest Flip-Chip packaging, and highly flexible port configurations up to x16
Productive Product: Let's start by clarifying a vital point: this story is about solar power adapters for conventional PCs, not about "solar-powered PCs" per se. You don't actually get a solar panel slapped to the side of your tower case; you get 86 pounds of schleppability. But you also get to help save the planet and circumvent your local
Catalyst Semiconductor, Inc. announced three devices which provide system processor power supply monitoring and reset functions. The CAT823, CAT824 and CAT825 voltage supervisors are available in a choice of seven standard threshold levels: 4.63V, 4.38V, 3.08V, 2.93V, 2.63V, 2.32V and 2.19V. In addition to an active-low reset output included on all three devices
Energy News: According to U.S. News & World Report, "Minnesota Gov. Tim Pawlenty, the new chair of the National Governors Association, was in Washington this week to argue that state governments should be a driving force in reducing the nation's dependence on foreign oil and in fighting greenhouse
Maxim Integrated Products introduces the MAX9796 2.3W, Class D audio subsystem. This device combines a high-efficiency, mono Class D amplifier; a DirectDrive stereo headphone amplifier; and a DirectDrive mono receiver amplifier. The device utilizes the company's active-emissions-limiting (AEL) circuitry and spread-spectrum-modulation technique, which reduce EMI and eliminate the output filters typically required by Class D amplifiers. The device provides Class AB performance with Class D efficiency.
Energy News: There's a big dose of clean-energy straight talk over at Forbes.com from physicist and investor Mark Mills. He says there is plenty of room for smart investments into alternative energies, because there wasn't much of a bubble in the first place, nor was there a bubble 30 years ago when many of the same technologies were going to save us from
Productive Products: Human harvesting. Algae pools. Wave power. Artificial tornados. Super kites. Tesla coils. The list reads like a high-tech version of the plagues that freed Moses' people in Egypt, but will these alternative energy concepts succeed or have the proverbial sea crash down on them? "True, many of the kookier-sounding concepts are still in deep development within large corporations, universities, and
Melexis announced the MLX90283 is single phase brushless vibration motor driver IC which allows increased battery life and delivers strong and clearly detected vibrations. The device integrates hall-effect sensor, digital and power driver circuitry into a low profile Ultra-thin QFN package and introduces the new proprietary ‘Active Start’ design to improve single phase vibration motor start-up reliability. The 1.8V to 3.6V operating voltage range perfectly suits battery-powered applications.
The MD2S from US Digital is a universal programmable microstepping stepper motor driver capable of driving size 17 to 42 stepper motors. DIP switches allow for the selection of 29 microstep resolutions from 5 to 256 microsteps per step. Motor currents are selectable from 0.5A to 7.0A per winding in 0.5 Amp increments. An L-option, low current version, is available with selectable current output from 0.20 to 3.6 Amps per winding in 0.05 Amp increments.
