| | | | Locating Discontinued ICs for Older Designs Just because an IC or a semiconductor device is discontinued by its original source does not mean that it is lost forever. There are a few semiconductor manufacturers specialized in making discontinued parts. One of them is Lansdale Semiconductor based in Phoenix, Arizona. The other is Rochester Electronics. | | | | | | Smartphones are Going Modular Like Google's project Ara, Kickstarter-funded startup Nexpaq is also turning a smartphone into a modular product. For that, Nexpaq has developed a modular smartphone case with a built-in MIPI interface to interconnect the add-on modules like an extra battery, amplified speaker, flash drive, laser pointer, and more. The company has raised $279,758 to go into production. | | | | | | | | Graphene Enables World's Thinnest Light Bulb Scientists from Columbia Engineering, Seoul National University (SNU), and Korea Research Institute of Standards and Science (KRISS) have jointly created the world's thinnest light bulb. For the first time, the scientists have demonstrated an on-chip visible light source using graphene as a filament. This study was led by Young Duck Kim, a postdoctoral research scientist in James Hone's group at Columbia Engineering. | | | | | | Battery Charger IC Significantly Cuts Charge Time Texas Instruments has released a new integrated single-cell Li-ion battery-charger IC, that utilizes the company's MaxCharge technology to reduce charge time. According to TI, charger designs based on this chip can reduce charge time by up to 60 percent compared to existing battery chargers. Besides maximizing the benefits of a faster charge time, the device also gives users a safer charging experience. | | | | | | | | | Low Supply Voltage 1MBd Digital Optocoupler Avago Technologies The Avago ACPL-M51L (single-channel, SO-5 package) is a low power, low supply voltage 1Mbd digital optocoupler, configurable as a 4-pin device. The device uses an insulating layer between the light emitting diode and an integrated photon detector to provide electrical insulation between the input and output. For more information. | | | | | Flexible, Low-jitter Universal Output Buffers Integrated Device Technology The 5P1103 and 5P1105 are programmable fanout buffers with universal outputs and very low additive phase jitter. Configurations can be stored in OTP memory or changed using an I2C interface. The small package and flexible output configuration saves board space, reduces component count, and lowers system cost. | | | | | | | | | |
