TotalCMOS Design Technique for Fast Zero
Power
Xilinx is the first to offer a TotalCMOS CPLD, both in pro-
cess technology and design technique. Xilinx employs a
cascade of CMOS gates to implement its product terms
instead of the traditional sense amp approach. This CMOS
gate implementation allows Xilinx to offer CPLDs which are

both high performance and low power, breaking the para-
digm that to have low power, you must have low perfor-
mance. This also makes it possible to manufacture high
density CPLDs like the XCR3320 that consume a fraction
of the power of competing devices. Refer to
