Development Kit

The Triton Development Kit-3 is based on the standard Triton-270 module and is supplied with Linux or Windows CE 5.0, other of which are developed in-house. Windows CE 6.0 is available as an option.

PXA270

Designed from the ground up for wireless clients and incorporating the latest advances in mobile technology, the PXA270 processors are the first Intel XScale cpu’s to include :

•	Wireless MMX technology that enables high-performance multimedia acceleration with an industry proven instruction set. In addition,
•	Quick Capture which is a flexible and powerful camera interface for capturing digital images and video.

While performance abounds in the Marvell PXA27x processor, power consumption is also a critical component. The new capabilities of Wireless Intel SpeedStep® Technology provide a quantum leap forward in low-power operation. Finally, the Marvell PXA27x family stacks Intel StrataFlash® memory and low-power SDRAM with the processor for more functionality in a smaller footprint.

Expansion

The TRITON-270 is supplied with a DIMM200 connector to provide the designer with access to the PXA270′s signals for nearly unlimited expansion. See the Specifications below or download the datasheet for full connector pin-outs.
