Texas Instruments Inc said on Monday it would demonstrate a prototype cell phone based on Android, the highly anticipated mobile phone operating system being built by Web search leader Google Inc.

The U.S. chip maker said the phone it will demonstrate at the Mobile World Congress trade show has "one button access" to key applications such as Web browsing, e-mail, messaging and video, making it easier for consumers to use such features.

The device will also allow for the integration of different applications, a capability mostly limited to desktop computers. For example, a real estate agent could combine information from its database with mapping software to let customers easily locate properties on the go, TI said.

The prototype handset will run on TI's OMAP850 phone processor, which includes Wi-Fi and Bluetooth short-range wireless connectivity.

Google had said on Friday that while a number of companies would demonstrate Android products at the wireless trade show, the prototypes would give no real indication of the actual devices customers would ultimately be able to buy.

TI is part of a group of about 30 companies that said they would support Google's operating system, which is based on Linux, an open-source software platform.

UK chip designer ARM Holdings Plc is also expected to show prototypes of devices based on Android at the show.

Service provider Deutsche Telekom's T-Mobile and Taiwanese phone maker High Tech Computer have both said they plan to sell phones based on Android this year.
