The Atom Zxxx CRB platform with the Intel Atom Z5xx series processor and US15W System Controller Hub. The Intel Atom processor Z5xx series delivers the benefits of Intel architecture for small form factor, thermally constrained and fanless embedded applications. Implemented in 45nm technology, these power-optimized processors provide robust performance-per-watt in an ultra-small 13x14 mm package. The Intel System Controller Hub (SCH) US15W integrates a graphics memory controller hub and an I/O controller hub into one small 22x22 mm package. This low-power platform has a combined thermal design power under five watts.
