Family Overview
The CoolRunner XPLA3 (eXtended Programmable Logic
Array) family of CPLDs is targeted for low power systems
that include portable, handheld, and power sensitive appli-
cations. Each member of the XPLA3 family includes Fast
Zero Power (FZP) design technology that combines low
power and high speed. With this design technique, the
XPLA3 family offers true pin-to-pin speeds of 5.0 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 cas-
caded chain of pure CMOS gates, the dynamic power is
also substantially lower than any competing CPLD. Cool-
Runner devices are the only TotalCMOS PLDs, as they use
both a CMOS process technology and the patented full
CMOS FZP design technique.
To the original XPLA architecture, XPLA3 adds a direct
input register path, multiple clocks (both dedicated and
product term generated), and both reset and preset for
each macrocell, with a full PLA structure. These enhance-
ments deliver high speed coupled with very flexible logic
allocation which results in the ability to make design
changes without changing pinout. The XPLA3 logic block
includes a pool of 48 product terms that can be allocated to
any macrocell in the logic block. Logic that is common to
multiple macrocells can be placed on a single PLA product
term and shared, effectively increasing design density.
XPLA3 CPLDs are supported by WebPACK from Xilinx and
industry standard CAE tools (Cadence/OrCAD, Exemplar
Logic, Mentor, Synopsys, Viewlogic, andd Synplicity), using
text (ABEL, VHDL, Verilog) and schematic capture design
entry. Design verification uses industry standard simulators
for functional and timing simulation. Development is sup-
ported on personal computer, Sparc, and HP platforms.
Device fitting uses Xilinx developed tools including
WebFITTER.
The XPLA3 family features also include industry-standard,
IEEE 1149.1, JTAG interface through which In-System Pro-
gramming (ISP) and reprogramming of the device can

I/O Cell
The OE (Output Enable) multiplexer has eight possible
modes (Figure 6), including a programmable weak pull-up
(WPU) eliminating the need for external termination on
unused I/Os.
The I/O Cell is 5V tolerant, and has a single-bit slew-rate
control for reducing EMI generation.
Outputs are 3.3V PCI electrical specification compatible
(no internal clamp diode).
