CoolRunner-II RealDigital Technology (WP171) - This white paper provides an overview of the RealDigital technology used in Xilinx CoolRunner-II CPLDs. RealDigital is the patented design technology used in Xilinx CoolRunner-II CPLDs that enable highperformance and ultra low power consumption in programmable logic devices. RealDigital is a key technology for CoolRunner-II CPLDs that minimizes system current demand and allows small chip-scale packaging options. Low-power designs are enabled through RealDigital by using true CMOS both in process technology and design technique.
