Hitachi has become the latest Japanese personal computer maker to choose the Crusoe microprocessor from start-up Transmeta to power one of its products.

The company will announce details of the new machine, a B5-size notebook computer, tomorrow.

Transmeta currently has three variations of the Crusoe microprocessor, the TM3200, TM5400 and TM5600.

Each differs in their features but at least one thing remains constant: low power consumption.

It is this feature that is attracting the attention of notebook computer manufacturers.

The limited amount of energy available from the machine's battery means manufacturers are keen to adopt any technology that might extend battery life.

So far companies with Crusoe-based machines include IBM, Sony, NEC, Gateway and Fujitsu.
