Chip maker Inteltoday announced it will unveil its latest microprocessor aimed at mobile phones and PDAs (personal digital assistants) next Tuesday.

Intel, best known for its line of processors used in desktop and notebook computers, is keen to grab a share of the mobile device marketplace. It has been selling StrongArm processors for mobile applications for some time, and stepped up its efforts in February this year when it launched its XScale processors.

A spokesman for Intel described the processor as a unique product, but declined to provide further details of the announcement to be made on Tuesday at events in Tokyo and Taipei.

At present there are two processors in the XScale range: the PXA250 aimed at PDAs and the PXA210 aimed at mobile phones.

Intel has also promised to deliver sometime later this year a new version of its XScale processor codenamed Manitoba. The chip combines a processor with a DSP (digital signal processor). DSPs are vital components in mobile phones and having one onboard alongside the processor in the chip will help handset makers reduce the size and power consumption of their products while also simplifying their design.

The latest addition to the company's range is the Manitoba processor, first announced at the Computex technology show back in June. The chip is due to go on sale by the end of this year.

"Manitoba is the next version of the XScale processor," said Michael Splinter, executive vice president of Intel. "It will really be geared at mobile phones and smart phones. While some people are already adopting our SA1110 StrongArm product and some will adopt our PXA250 [XScale], Manitoba is the product that has great power levels and application base for mobiles phones," he said.

In addition to a new processor, Intel today announced it will also be unveiling new flash memory chips for mobile phones.
