Description
The XCR5064C CPLD (Complex Programmable Logic
Device) is the second in a family of CoolRunner™ CPLDs
from Xilinx Semiconductors. These devices combine high
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
results in worst case t_PD's of only 9.5 ns from any pin to any
other pin. In addition, logic that is common to multiple out-
puts can be placed on a single PLA product term and
shared across multiple outputs via the OR array, effectively
increasing design density.
The XCR5084C CPLDs are supported by industry stan-
dard 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.
The XCR5064C CPLD is reprogrammable using industry
standard device programmers from vendors such as Data
I/O, BPMicrosystems, SMS, and others. The XCR5064C
also includes an industry-standard, IEEE 1149.1, JTAG
interface through which In-System Programming (ISP) and
reprogramming of the device are supported.
