FEATURES
•
Industry’s first TotalCMOS™ PLD – both CMOS design and
•
Fast Zero Power (FZP™) design technique provides ultra-low
power and very high speed
process technologies
DESCRIPTION
The PZ3032 CPLD (Complex Programmable Logic Device) is the
first in a family of Fast Zero Power (FZP™) CPLDs from Philips
Semiconductors. These devices combine high speed and zero
power in a 32 macrocell CPLD. With the FZP™ design technique,
the PZ3032 offers true pin-to-pin speeds of 8ns, while
simultaneously delivering power that is less than 35µA 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 CPLD
– 70% lower at 50MHz. These devices are the first TotalCMOS™
PLDs, as they use both a CMOS process technology
and
the
patented full CMOS FZP™ design technique. For 5V applications,
Philips also offers the high speed PZ5032 CPLD that offers
pin-to-pin speeds of 6ns.
The Philips FZP™ CPLDs introduce the new patent-pending 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 8ns PAL™
path with 5 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 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 2.5ns, regardless of the number of PLA product terms
used, which results in worst case t
PD
’s of only 10.5ns 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 PZ3032 CPLDs are supported by industry standard CAE tools
(Cadence, Mentor, Synopsys, Synario, Viewlogic, OrCAD), using
text (Abel, VHDL, Verilog) and/or schematic entry. Design
verification uses industry standard simulators for functional and
timing simulation. Development is supported on personal computer,
Sparc, and HP platforms. Device fitting uses either Minc or Philips
Semiconductors-developed tools.
The PZ3032 CPLD is reprogrammable using industry standard
device programmers from vendors such as Data I/O, BP
Microsystems, SMS, and others.

XPLA™ ARCHITECTURE
Figure 1 shows a high level block diagram of a 64 macrocell device
implementing the XPLA™ architecture. The XPLA™ architecture
consists of logic blocks that are interconnected by a Zero-power
Interconnect Array (ZIA). The ZIA is a virtual crosspoint switch. Each
logic block is essentially a 36V16 device with 36 inputs from the ZIA
and 16 macrocells. Each logic block also provides 32 ZIA feedback
paths from the macrocells and I/O pins.
From this point of view, this architecture looks like many other CPLD
architectures. What makes the CoolRunner™ family unique is what
is inside each logic block and the design technique used to
implement these logic blocks. The contents of the logic block will be
described next.
PRODUCT terms, and are used to control the preset/reset and
output enables of the 16 macrocells’ flip-flops. The PAL array
consists of a programmable AND array with a fixed OR array, while
the PLA array consists of a programmable AND array with a
programmable OR array. The PAL array provides a high speed path
through the array, while the PLA array provides increased product
term density.
Each macrocell has 5 dedicated product terms from the PAL array.
The pin-to-pin t
PD
of the PZ3032 device through the PAL array is
8ns. This performance is the fastest 3 volt CPLD available today. If a
macrocell needs more than 5 product terms, it simply gets the
additional product terms from the PLA array. The PLA array consists
of 32 product terms, which are available for use by all 16
macrocells. The additional propagation delay incurred by a
macrocell using 1 or all 32 PLA product terms is just 2.5ns. So the
total pin-to-pin t
PD
for the PZ3032 using 6 to 37 product terms is
10.5ns (8ns for the PAL + 2.5ns for the PLA).
Logic Block Architecture
Figure 2 illustrates the logic block architecture. Each logic block
contains control terms, a PAL array, a PLA array, and 16 macrocells.

Macrocell Architecture
Figure 3 shows the architecture of the macrocell used in the
CoolRunner™ family. The macrocell consists of a flip-flop that can be
configured as either a D or T type. A D-type flip-flop is generally
more useful for implementing state machines and data buffering. A
T-type flip-flop is generally more useful in implementing counters. All
CoolRunner™ family members provide both synchronous and
asynchronous clocking and provide the ability to clock off either the
falling or rising edges of these clocks. These devices are designed
such that the skew between the rising and falling edges of a clock
are minimized for clocking integrity. There are 2 clocks (CLK0 and
CLK1) available on the PZ3032 device. Clock 0 (CLK0) is
designated as the “synchronous” clock and must be driven by an
external source. Clock 1 (CLK1) can either be used as a
synchronous clock (driven by an external source) or as an
asynchronous clock (driven by a macrocell equation).
Two of the control terms (CT0 and CT1) are used to control the
Preset/Reset of the macrocell’s flip-flop. The Preset/Reset feature
for each macrocell can also be disabled. Note that the Power-on
Reset leaves all macrocells in the “zero” state when power is
properly applied. The other 4 control terms (CT2–CT5) can be used
to control the Output Enable of the macrocell’s output buffers. The
reason there are as many control terms dedicated for the Output
Enable of the macrocell is to insure that all CoolRunner™ devices
are PCI compliant. The macrocell’s output buffers can also be
always enabled or disabled. All CoolRunner™ devices also provide a
Global Tri-State (GTS) pin, which, when pulled Low, will 3-State all
the outputs of the device. This pin is provided to support “In-Circuit
Testing” or “Bed-of-Nails Testing”.
There are two feedback paths to the ZIA: one from the macrocell,
and one from the I/O pin. The ZIA feedback path before the output
buffer is the macrocell feedback path, while the ZIA feedback path
after the output buffer is the I/O pin ZIA path. When the macrocell is
used as an output, the output buffer is enabled, and the macrocell
feedback path can be used to feedback the logic implemented in the
macrocell. When the I/O pin is used as an input, the output buffer
will be 3-Stated and the input signal will be fed into the ZIA via the
I/O feedback path, and the logic implemented in the buried
macrocell can be fed back to the ZIA via the macrocell feedback
path. It should be noted that unused inputs or I/Os should be
properly terminated.
