The XCR3128 CPLD (Complex Programmable Logic Device) is the third in a family of CoolRunner CPLDs from Xilinx. These devices combine high speed and zero power in a 128 macrocell CPLD. With the FZP design technique, the XCR3128 offers true pin-to-pin speeds of 10 ns, while simultaneously delivering power that is less than 100 A at standby without the need for ` turbo-bits' or other power-down schemes. By replacing conventional sense amplifier methods for implementing product terms (a technique that has been used in PLDs since the bipolar era) with a cascaded chain of pure CMOS gates, the dynamic power is also substantially lower than any competing CPLD. These devices are the first TotalCMOS PLDs, as they use both a CMOS process technology and the patented full CMOS FZP design technique. For 5V applications, Xilinx also offers the high speed XCR5128 CPLD that offers these features in a full 5V implementation.
