XSscale PXA270 Power in small form factor

The Intel® Xscale (Now Marvell) PXA270 is the heart of the BitsyXb. This powerful embedded PXA270 single board computer provides dynamic (variable) speed and voltage regulation, and includes 5 low power modes which ADS has leveraged throughout its low-level software code to make PXA270 power-stingy, and perfect for handheld, wearable and unmanned applications. The Xscale BitsyXb, like its PXA255-based sister product, the BitsyX, is compact and robust with features including ADSmartIO™, and power-thrifty using ADSmartPower™ with partitioning for optimal power usage. ADS systems have been successfully deployed in several battery-backed embedded applications including PDA/handheld, instrumentation, medical monitoring, telematics, and several others. The BitsyXb can be used either as a stand-alone system or configured using a personality board for expandability.
