Using Suspend Mode in Spartan-3 Generation FPGAs
Author: Xilinx

The Spartan-3A, Spartan-3AN, and Spartan-3A DSP FPGA families offer an advanced static power management feature called Suspend mode, which reduces FPGA power consumption while retaining the FPGA’s configuration data and maintaining the application state. The device can quickly enter and exit Suspend mode as required in an application.
