This means that the exact same parts can be used for high-speed data communications/ computing systems and leading edge portable products, with the added benefit of In System Programming. Low power consumption and high-speed operation are combined into a single family that is easy to use and cost effective. Clocking techniques and other power saving features extend the users’ power budget.
