Description
•
Industry's first TotalCMOS™ PLD - both CMOS design
and process technologies
The XCR5032C CPLD (Complex Programmable Logic
Device) is a member of the CoolRunner® family of CPLDs
from Xilinx. These devices combine high speed and zero
power in a 32 macrocell CPLD. With the FZP design tech-
nique, the XCR5032C offers true pin-to-pin speeds of 6 ns,
while simultaneously delivering power that is less than
75 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 tech-
nique 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 pat-
ented full CMOS FZP design technique. For 3V applica-
tions, Xilinx also offers the high speed XCR3032C CPLD
that offers pin-to-pin speeds of 8 ns.

The Xilinx FZP CPLDs utilize the patented XPLA (extended
Programmable Logic Array) architecture. The XPLA archi-
tecture combines the best features of both PLA and PAL
type structures to deliver high speed and flexible logic allo-
cation that results in superior ability to make design
changes with fixed pinouts. The XPLA structure in each
logic block provides a fast 6 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 efficiently through-
out 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 ns, regardless of
the number of PLA product terms used, which results in
worst case tPD’s of only 8 ns from any pin to any other pin.
In addition, logic that is common to multiple outputs can be
placed on a single PLA product term and shared across
multiple outputs via the OR array, effectively increasing
design density.

The XCR5032C CPLDs are supported by industry standard
CAE tools (Cadence/OrCAD, Exemplar Logic, Mentor,
Synopsys, Synario, Viewlogic, and Synplicity), using text
(ABEL, VHDL, Verilog) and/or schematic entry. Design ver-
ification uses industry standard simulators for functional
and timing simulation. Development is supported on per-
sonal computer, Sparc, and HP platforms. Device fitting
uses Xilinx developed tools including WebFITTER.
