Agilent offers its LaserStream technology as separate components or in bundles that include the sensor, VCSEL, round or rectangular lens, and a VCSEL assembly clip. The new devices include the ADNS-6000 laser navigation sensor, also available as the ADNB-600X bundle, for high-end corded mice. This sensor features 800 cpi resolution, 20 ips maximum velocity and 6,400 fps frame rate. The resolution is selectable at 400 or 800 cpi.Click here for the ADNS-6000 product overview.

The ADNS-6030 low-power laser navigation sensor, also available as the ADNB-603X bundle, for high-end cordless mice, offers up to 800 cpi resolution (selectable at 400 or 800 cpi), 20 ips maximum velocity, and enhanced self-adjusting frame rate. It features self-adjusting power-saving modes for long battery life up to six months, and offers a wide operating voltage of 2.7 V to 3.6 V. Click here for the ADNS-6030 product overview.

The high-performance ADNS-6010 laser navigation sensor, also available as the ADNB-601X bundle, is optimized for the gaming environment and other high-performance applications. It touts a 2,000 cpi resolution, 45 ips maximum velocity and 7,080 fps frame rate. The resolution is selectable in firmware at 400, 800, 1600 or 2000 counts per inch (cpi).Click here for the ADNS-6010 product overview.

What makes it specific for gaming is that it has a very high performance level in terms of velocity and acceleration — how fast the user can move the mouse — and also the resolution — how small a movement the user can move the mouse and have the sensor still pick it up,” Liu said.

Here's how the laser-based mouse stacks up against the company's LED-based optical mouse sensor. The new ADNS-6010 laser sensor for gaming mice offers a resolution as high as 2000 cpi as compared with the company's most recent LED-based optical mouse sensor, the ADNS-3080, which offers a resolution as high as 1600 cpi for gaming mice. In addition, the ADNS6010 touts a velocity of 45 ips and acceleration of 20 g compared with 40 ips and 15 g, respectively, for the ADNS-3080.

The ADNS-6030-based bundle (ADNB-603X) is priced at less than $5 in high volumes, the ADNB-600X bundle at less than $6, and the ADNB-601X bundle at less than $7. The sensors, bundles and individual ADNV-6330 VCSELs, optics and clips are available now. The company plans to develop entry-level sensors and bundles at a lower cost some time next year.

Flash has a very small cell size, but embedding flash doesn't make sense unless you are going to embed a lot of memory,” Moise said. That's because of all the overhead circuitry you need with flash to handle the high voltage. If you only need a few megabits of memory on your embedded chip, like a microcontroller, it doesn't make sense to use flash with all its overhead.”

TI expects to begin sampling 4-Mbit standalone FRAM chips to Ramtron later this year, but the company does not expect to add FRAM to any of its embedded chips until late 2006 or 2007.

What's next The next-best bet behind FRAM is MRAM, which stores a bit in a magnetic-tunnel junction, a sandwich structure that includes a pinned magnetic layer, an oxide tunnel barrier and a free magnetic layer. Two metal electrodes switch the free layer between two magnetic-polarization states. Reading is accomplished by sensing a change in resistance.

MRAMs have been researched for many years at Altis Semiconductor (an alliance of IBM and Infineon), Freescale, NEC/Toshiba, Samsung and Sony. Several of these companies have announced successful experimental chips as large as 128 kbits, while Cypress Semiconductor Corp. (San Jose, Calif.) reported densities up to 256 kbits. Cypress, however, recently said it will divest itself of Silicon Magnetic Systems, the subsidiary founded to commercialize MRAMs (see www.eet.com/article/showArticle.jhtml?articleID=60400459).

Also scaling back is NVE Corp. (Eden Prairie, Minn.). NVE recently said it had discontinued its efforts to sell standalone MRAM devices (visit www.eetimes.com/showArticle.jhtml?articleID=160904080). Now, it will sell only its intellectual property for a 256-kbit MRAM design MRAM has fast read/write as well as high density, and you can get an MRAM cell in many manufacturers' libraries today,” said Denali's Mason. The problem with MRAM has been lifetime, durability and reproducibility.”
