Forbes.com: Motorola's Phone On A Chip

Chipmaker Motorola is expected to announce a mobile phone chip it says will combine most of the circuitry for a smart mobile phone onto a single chip. It will call the chip the Mobile Extreme Convergence architecture, or MXC.

The MXC chip can be used in devices designed to handle a multitude of wireless functions, including standard wireless phone and data connections, as well as other types of wireless connections including Bluetooth and Wi-Fi, and can receive signals from Global Positioning System satellites. The chip is about the size of the postage stamp; a similar collection of mobile phone components typically requires a space the size of a business card.

Motorola says that manufacturers have a choice of as many of 400 different components to assemble the right combination for their devices. Having a single chip will offer them a simpler choice to get the job done, it contends. This chip is expected to debut with transistor sizes of 90 nanometers by mid-2005 and then switch to 65-nanometer technology in 2006.
