Abstract
A programmable logic device is provided with multiple power supplies such that, in one mode of operation, power can be disconnected from at least one part of the programmable logic device, while maintaining power at least to an interface component of the programmable logic device, or to a memory component in which current configuration data are stored, thereby avoiding the need for a configuration sequence when power is reapplied to the whole device. The programmable logic device may be provided as an integrated circuit, having multiple pairs of pins for connection to a supply voltage. Each of the pairs of pins provides power for a different subsection of the programmable logic device.
