Product Specification
speed and zero power in a 64 macrocell CPLD. With the
FZP design technique, the XCR5064C offers true pin-to-pin
speeds of 7.5 ns, while simultaneously delivering power
that is less than 100 µA 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 CPLDz. These devices are the first TotalC-
MOS PLDs, as they use both a CMOS process technology
and the patented full CMOS FZP design technique.

The Xilinx FZP CPLDs utilize the patented XPLA
(eXtended Programmable Logic Array) architecture. The
XPLA architecture combines the best features of both PLA
and PAL type structures to deliver high speed and flexible
logic allocation that results in superior ability to make
design changes with fixed pinouts. The XPLA structure in
each logic block provides a fast 7.5 ns PAL path with five
dedicated product terms per output. This PAL path is joined
by an additional PLA structure that deploys a pool of 32
product terms to a fully programmable OR array that can
allocate the PLA product terms to any output in the logic
block. This combination allows logic to be allocated effi-
ciently throughout the logic block and supports as many as
37 product terms on an output. The speed with which logic
is allocated from the PLA array to an output is only 2.0 ns,
regardless of the number of PLA product terms used, which
