In this particular work, we have done power dissipation analysis of DES algorithm, implemented on 28nm FPGA. We have used Xilinx ISE software development kit for all the observation done in this particular research work. Here, we have taken SSTL (Stub-Series Terminated Logic) as input-output standard. We have considered six subcategories of SSTL (i. e. SSTL135, SSTL135_R, SSTL15, SSTL15_R, SSTL18_I and SSTL18_II) for four different WLAN frequencies (i. e. 2.4GHz, 3.6GHz, 4.9GHz, and 5.9GHz). We have done analysis considering five basic powers i. e. clock power, logic power, signal power, IOs power, leakage power and total power. There is 50-60% reduction in power dissipation, which is possible with proper selection of the most energy efficient IO standards i. e. SSTL135_R among SSTL logic families.
