An Electronicstalk guide

Start with the news release Power MOSFETs offer lower on-resistance from Vishay Siliconix, which we summarised at the time by saying "P-channel power MOSFET family in PowerPAK SC-75 packages includes several devices rated from 8 to 30V that are industry firsts for their voltage ratings in this package type.". Several months prior to that, we featured the news release Graphics core provides depth of texture from Vivante Corporation: "The Depth Texture extension to the OpenGL ES 2.0 application programming interface enables dynamic shadow rendering.".

In August 2008, we covered the news from Fairchild Semiconductor - take a look at Voltage translator covers a wide range which says: "I2C interface and open drain output offers designers a simple way to interface with Bluetooth and display screens in cellphones, notebooks and other applications.".

Take a look also at the news release from Green Hills Software, Software secures devices in the field, as well as Upgrade for GPS tuner core IP from MIPS Technologies, and Voice processor clears up Korean calls from Audience.
