54SX Family FPGAs
G e n e ra l D e s cr i p t i o n
Actel’s SX family of FPGAs features a sea-of-modules
architecture that delivers device performance and
integration levels not currently achieved by any other FPGA
architecture. SX devices greatly simplify design time, enable
dramatic reductions in design costs and power
consumption, and further decrease time to market for
performance-intensive applications.
machines, and datapath logic. The general system of
segmented routing tracks allows any logic module in the
array to be connected to any other logic or I/O module.
Within this system, propagation delay is minimized by
limiting the number of antifuse interconnect elements to
five (90 percent of connections typically use only three
antifuses). The unique local and general routing structure
featured in SX devices gives fast and predictable
performance, allows 100 percent pin-locking with full logic
utilization, enables concurrent PCB development, reduces
design time, and allows designers to achieve performance
goals with minimum effort.
Actel’s SX architecture features two types of logic modules,
the combinatorial cell (C-cell) and the register cell (R-cell),
each optimized for fast and efficient mapping of synthesized
logic functions. The routing and interconnect resources are
in the metal layers above the logic modules, providing
optimal use of silicon. This enables the entire floor of the
device to be spanned with an uninterrupted grid of
fine-grained, synthesis-friendly logic modules (or
“sea-of-modules”), which reduces the distance signals have
to travel between logic modules. To minimize signal
propagation delay, SX devices employ both local and general
routing resources. The high-speed local routing resources
(DirectConnect and FastConnect) enable very fast local
signal propagation that is optimal for fast counters, state
Further complementing SX’s flexible routing structure is a
hard-wired, constantly loaded clock network that has been
tuned to provide fast clock propagation with minimal clock
skew. Additionally, the high performance of the internal
logic has eliminated the need to embed latches or flip-flops
in the I/O cells to achieve fast clock-to-out or fast input
set-up times. SX devices have easy-to-use I/O cells that do
not require HDL instantiation, facilitating design re-use and
reducing design and verification time.

54SX Family FPGAs
S X F a m i l y A r ch i t e c tu r e
The SX family architecture was designed to satisfy
next-generation performance and integration requirements
for production-volume designs in a broad range of
applications.
antifuse interconnect elements, which are embedded
between the M2 and M3 layers. The antifuses are normally
open circuit and, when programmed, form a permanent
low-impedance connection.
P r o g r a m m a b l e I n t e r c o nn e c t E l e m e n t
The extremely small size of these interconnect elements
gives the SX family abundant routing resources and provides
excellent protection against design pirating. Reverse
engineering is virtually impossible because it is extremely
difficult to distinguish between programmed and
unprogrammed antifuses, and there is no configuration
bitstream to intercept.
The SX family provides efficient use of silicon by locating the
routing interconnect resources between the Metal 2 (M2)
and Metal 3 (M3) layers (Figure 1). This completely
eliminates the channels of routing and interconnect
resources between logic modules (as implemented on SRAM
FPGAs and previous generations of antifuse FPGAs), and
enables the entire floor of the device to be spanned with an
uninterrupted grid of logic modules.
Interconnection between these logic modules is achieved
using Actel’s patented metal-to-metal programmable
Additionally, the interconnect (i.e., the antifuses and metal
tracks) have lower capacitance and lower resistance than
any other device of similar capacity, leading to the fastest
signal propagation in the industry.

Figure 1 • SX Family Interconnect Elements
Lo g ic M o du le D es ig n
The SX family architecture is described as a
“sea-of-modules” architecture because the entire floor of
the device is covered with a grid of logic modules with
virtually no chip area lost to interconnect elements or
routing. Actel’s SX family provides two types of logic
modules, the register cell (R-cell) and the combinatorial
cell (C-cell).
4
The R-cell contains a flip-flop featuring asynchronous clear,
asynchronous preset, and clock enable (using the S0 and S1
lines) control signals (Figure 2 on page 5). The R-cell
registers feature programmable clock polarity selectable on
a register-by-register basis. This provides additional
flexibility while allowing mapping of synthesized functions
into the SX FPGA. The clock source for the R-cell can be
chosen from either the hard-wired clock or the routed clock.
v3.1
5 4 S X F a m i l y F PG A s
The C-cell implements a range of combinatorial functions
up to 5-inputs (Figure 3). Inclusion of the DB input and its
associated inverter function dramatically increases the
number of combinatorial functions that can be
implemented in a single module from 800 options in
previous architectures to more than 4,000 in the SX
architecture. An example of the improved flexibility
S0
enabled by the inversion capability is the ability to integrate
a 3-input exclusive-OR function into a single C-cell. This
facilitates construction of 9-bit parity-tree functions with 2
ns propagation delays. At the same time, the C-cell
structure is extremely synthesis friendly, simplifying the
overall design and reducing synthesis time.

Chip Architecture
Type 2 contains one C-cell and two R-cells.
The SX family’s chip architecture provides a unique
approach to module organization and chip routing that
delivers the best register/logic mix for a wide variety of new
and emerging applications.
To increase design efficiency and device performance, Actel
has further organized these modules into SuperClusters
(Figure 4 on page 6). SuperCluster 1 is a two-wide grouping
of Type 1 clusters. SuperCluster 2 is a two-wide group
containing one Type 1 cluster and one Type 2 cluster. SX
devices feature more SuperCluster 1 modules than
SuperCluster 2 modules because designers typically require
significantly more combinatorial logic than flip-flops.

horizontal banks called Clusters. There are two types of

Figure 4 • Cluster Organization
Ro ut in g Re so u r ce s
Clusters and SuperClusters can be connected through the
use of two innovative local routing resources called
FastConnect and DirectConnect, which enable extremely
fast and predictable interconnection of modules within
Clusters and SuperClusters (Figure 5 and Figure 6 on
page 7). This routing architecture also dramatically reduces
the number of antifuses required to complete a circuit,
ensuring the highest possible performance.
DirectConnect is a horizontal routing resource that provides
connections from a C-cell to its neighboring R-cell in a given
SuperCluster. DirectConnect uses a hard-wired signal path
requiring no programmable interconnection to achieve its
fast signal propagation time of less than 0.1 ns.
FastConnect enables horizontal routing between any two
logic modules within a given SuperCluster and vertical
routing with the SuperCluster immediately below it. Only
one programmable connection is used in a FastConnect
path, delivering maximum pin-to-pin propagation of 0.4 ns.
6
In addition to DirectConnect and FastConnect, the
architecture makes use of two globally oriented routing
resources known as segmented routing and high-drive
routing. Actel’s segmented routing structure provides a
variety of track lengths for extremely fast routing between
SuperClusters. The exact combination of track lengths and
antifuses within each path is chosen by the 100 percent
automatic place and route software to minimize signal
propagation delays.
Actel’s high-drive routing structure provides three clock
networks. The first clock, called HCLK, is hard wired from
the HCLK buffer to the clock select MUX in each R-cell. This
provides a fast propagation path for the clock signal,
enabling the 3.7 ns clock-to-out (pin-to-pin) performance of
the SX devices. The hard-wired clock is tuned to provide
clock skew as low as 0.25 ns. The remaining two clocks
(CLKA, CLKB) are global clocks that can be sourced from
external pins or from internal logic signals within the SX
device.

programmed (“on” state) resistance of 25Ω with
capacitance of 1.0 fF for low signal impedance.

P e r f o r m an c e
B o u nd a r y S c an T e st i ng ( B S T )
The combination of architectural features described above
enables SX devices to operate with internal clock
frequencies exceeding 300 MHz, enabling very fast
execution of even complex logic functions. Thus, the SX
family is an optimal platform upon which to integrate the
functionality previously contained in multiple CPLDs. In
addition, designs that previously would have required a gate
array to meet performance goals can now be integrated into
an SX device with dramatic improvements in cost and time
to market. Using timing-driven place and route tools,
designers can achieve highly deterministic device
performance. With SX devices, designers do not need to use
complicated performance-enhancing design techniques
such as the use of redundant logic to reduce fanout on
critical nets or the instantiation of macros in HDL code to
achieve high performance.
All SX devices are IEEE 1149.1 compliant. SX devices offer
superior diagnostic and testing capabilities by providing
Boundary Scan Testing (BST) and probing capabilities.
These functions are controlled through the special test pins
in conjunction with the program fuse. The functionality of
each pin is described in Table 2.In the dedicated test mode,
TCK, TDI and TDO are dedicated pins and cannot be used as
regular I/Os. In flexible mode, TMS should be set HIGH
through a pull-up resistor of 10kΩ. TMS can be pulled LOW
to initiate the test sequence.
The program fuse determines whether the device is in
dedicated or flexible mode. The default (fuse not blown) is
flexible mode. .
Table 2 • Boundary Scan Pin Functionality
I/O Modules
Each I/O on an SX device can be configured as an input, an
output, a tristate output, or a bidirectional pin. Even without
the inclusion of dedicated I/O registers, these I/Os, in
combination with array registers, can achieve clock-to-out
(pad-to-pad) timing as fast as 3.7 ns. I/O cells that have
embedded latches and flip-flops require instantiation in
HDL code; this is a design complication not encountered in
SX FPGAs. Fast pin-to-pin timing ensures that the device
will have little trouble interfacing with any other device in
the system, which in turn enables parallel design of system
components and reduces overall design time.
P o w er R e q u i r e m e nt s
The SX family supports 3.3V operation and is designed to
tolerate 5.0V inputs. (Table 1). Power consumption is
extremely low due to the very short distances signals are
required to travel to complete a circuit. Power requirements
are further reduced because of the small number of
low-resistance antifuses in the path. The antifuse
architecture does not require active circuitry to hold a
charge (as do SRAM or EPROM), making it the lowest-power
architecture on the market.

The SX devices are fully supported by Actel’s line of FPGA
development tools, including the Actel DeskTOP series and
Designer Advantage tools. The Actel DeskTOP series is an
integrated design environment for PCs that includes design
entry, simulation, synthesis, and place and route tools.
Designer Advantage, Actel’s suite of FPGA development
point tools for PCs and Workstations, includes the ACTgen
Macro Builder, Designer with DirectTime timing driven
place and route and analysis tools, and device programming
software.
In addition, the SX devices contain ActionProbe circuitry
that provides built-in access to every node in a design,
enabling 100-percent real-time observation and analysis of a
device's internal logic nodes without design iteration. The
probe circuitry is accessed by Silicon Explorer II, an
easy-to-use integrated verification and logic analysis tool
that can sample data at 100 MHz (asynchronous) or 66 MHz
(synchronous). Silicon Explorer II attaches to a PC’s
standard COM port, turning the PC into a fully functional
18-channel logic analyzer. Silicon Explorer II allows
designers to complete the design verification process at
their desks and reduces verification time from several hours
per cycle to only a few seconds.

The TDI, TCK, TDO, PRA, and PRB pins should not be used
as input or bidirectional ports. Because these pins are
active during probing, critical signals input through these
pins are not available while probing. In addition, the
Security Fuse should not be programmed because doing so
disables the Probe Circuitry.

Notes:
1. Stresses beyond those listed under “Absolute Maximum
Ratings” may cause permanent damage to the device.
Exposure to absolute maximum rated conditions for extended
periods may affect device reliability. Device should not be
operated outside the Recommended Operating Conditions.
2. VCCR in the A54SX16P must be greater than or equal to VCCI
during power-up and power-down sequences and during
normal operation.
3. Device inputs are normally high impedance and draw
extremely low current. However, when input voltage is greater
than VCC + 0.5V or less than GND – 0.5V, the internal protection
diodes will forward-bias and can draw excessive current.

Notes:
1. Input leakage currents include hi-Z output leakage for all bi-directional buffers with tri-state outputs.
2. Signals without pull-up resistors must have 3 mA low output current. Signals requiring pull up must have 6 mA; the latter include,
FRAME#, IRDY#, TRDY#, DEVSEL#, STOP#, SERR#, PERR#, LOCK#, and, when used AD[63::32], C/BE[7::4]#, PAR64, REQ64#, and ACK64#.
3. Absolute maximum pin capacitance for a PCI input is 10 pF (except for CLK).
4. Lower capacitance on this input-only pin allows for non-resistive coupling to AD[xx].

Notes:
1. Refer to the V/I curves in Figure 8. Switching current characteristics for REQ# and GNT# are permitted to be one half of that specified here;
i.e., half size output drivers may be used on these signals. This specification does not apply to CLK and RST# which are system outputs.
“Switching Current High” specification are not relevant to SERR#, INTA#, INTB#, INTC#, and INTD# which are open drain outputs.
2. Note that this segment of the minimum current curve is drawn from the AC drive point directly to the DC drive point rather than toward
the voltage rail (as is done in the pull-down curve). This difference is intended to allow for an optional N-channel pull-up.
3. Maximum current requirements must be met as drivers pull beyond the last step voltage. Equations defining these maximums (A and B)
are provided with the respective diagrams in Figure 8. The equation defined maxima should be met by design. In order to facilitate
component testing, a maximum current test point is defined for each side of the output driver.
4. This parameter is to be interpreted as the cumulative edge rate across the specified range, rather than the instantaneous rate at any point
within the transition range. The specified load (diagram below) is optional; i.e., the designer may elect to meet this parameter with an
unloaded output per revision 2.0 of the PCI Local Bus Specification. However, adherence to both maximum and minimum parameters is
now required (the maximum is no longer simply a guideline). Since adherence to the maximum slew rate was not required prior to
revision 2.1 of the specification, there may be components in the market for some time that have faster edge rates; therefore, motherboard
designers must bear in mind that rise and fall times faster than this specification could occur, and should ensure that signal integrity
modeling accounts for this. Rise slew rate does not apply to open drain outputs.

Notes:
1. This specification should be guaranteed by design. It is the minimum voltage to which pull-up resistors are calculated to pull a floated
network. Applications sensitive to static power utilization should assure that the input buffer is conducting minimum current at this
input voltage.
2. Input leakage currents include hi-Z output leakage for all bi-directional buffers with tri-state outputs.
3. Absolute maximum pin capacitance for a PCI input is 10pF (except for CLK).

dissipation is defined as follows:
A critical element of system reliability is the ability of
electronic devices to safely dissipate the heat generated
during operation. The thermal characteristics of a circuit
depend on the device and package used, the operating
temperature, the operating current, and the system's ability
to dissipate heat.

(0.5 * (s1 * CEQHV * fs1) + (CEQHF * fs1))HCLK]
You should complete a power evaluation early in the design
process to help identify potential heat-related problems in
the system and to prevent the system from exceeding the
device’s maximum allowed junction temperature.
The actual power dissipated by most applications is
significantly lower than the power the package can
dissipate. However, a thermal analysis should be performed
for all projects. To perform a power evaluation, follow these
steps:

your application.

Sample Power Calculation
One of the designs used to characterize the A54SX family
was a 528 bit serial in serial out shift register. The design
utilized 100% of the dedicated flip-flops of an A54SX16P
device. A pattern of 0101… was clocked into the device at
frequencies ranging from 1 MHz to 200 MHz. Shifting in a
series of 0101… caused 50% of the flip-flops to toggle from
low to high at every clock cycle.
Follow the steps below to estimate power consumption. The
values provided for the sample calculation below are for the
shift register design above. This method for estimating
power consumption is conservative and the actual power
consumption of your design may be less than the estimated
power consumption.
The total power dissipation for the 54SX family is the sum of
the AC power dissipation and the DC power dissipation.

The temperature that you select in Designer Series software
is the junction temperature, not ambient temperature. This
is an important distinction because the heat generated from
dynamic power consumption is usually hotter than the
ambient temperature. Use the equation below to calculate
junction temperature.
θja = Junction to ambient of package. θja numbers are
located in Package Thermal Characteristics section.
P a ck a g e T he r m a l C h a r ac t e ri s ti cs
The device junction to case thermal characteristic is θjc,
and the junction to ambient air characteristic is θja. The
thermal characteristics for θja are shown with two different
air flow rates.
Junction Temperature = ∆T + Ta
Where:
Ta = Ambient Temperature
∆T = Temperature gradient between junction (silicon) and
ambient
The maximum junction temperature is 150°C.
A sample calculation of the absolute maximum power
dissipation allowed for a TQFP 176-pin package at

Timing characteristics for 54SX devices fall into three
categories: family-dependent, device-dependent, and
design-dependent. The input and output buffer
characteristics are common to all 54SX family members.
Internal routing delays are device dependent. Design
dependency means actual delays are not determined until
after placement and routing of the user’s design is complete.
Delay values may then be determined by using the
DirectTime Analyzer utility or performing simulation with
post-layout delays.
Some nets in the design use long tracks. Long tracks are
special routing resources that span multiple rows, columns,
or modules. Long tracks employ three and sometimes five
antifuse connections. This increases capacitance and
resistance, resulting in longer net delays for macros
connected to long tracks. Typically up to 6% of nets in a fully
utilized device require long tracks. Long tracks contribute
approximately 4 ns to 8.4 ns delay. This additional delay is
represented statistically in higher fanout (FO=24) routing
delays in the data sheet specifications section.
C r i t ic al N e t s a nd T yp ic a l N e t s
Timing Derating
Propagation delays are expressed only for typical nets,
which are used for initial design performance evaluation.
Critical net delays can then be applied to the most
time-critical paths. Critical nets are determined by net
property assignment prior to placement and routing. Up to
6% of the nets in a design may be designated as critical,
while 90% of the nets in a design are typical.
54SX devices are manufactured in a CMOS process.
Therefore, device performance varies according to
temperature, voltage, and process variations. Minimum
timing parameters reflect maximum operating voltage,
minimum operating temperature, and best-case processing.
Maximum timing parameters reflect minimum operating
voltage, maximum operating temperature, and worst-case
processing.

Notes:
1. For dual-module macros, use tPD + tRD1 + tPDn , tRCO + tRD1 + tPDn or tPD1 + tRD1 + tSUD , whichever is appropriate.
2. Routing delays are for typical designs across worst-case operating conditions. These parameters should be used for estimating device
performance. Post-route timing analysis or simulation is required to determine actual worst-case performance. Post-route timing is
based on actual routing delay measurements performed on the device prior to shipment.

Notes:
1. For dual-module macros, use tPD + tRD1 + tPDn , tRCO + tRD1 + tPDn or tPD1 + tRD1 + tSUD , whichever is appropriate.
2. Routing delays are for typical designs across worst-case operating conditions. These parameters should be used for estimating device
performance. Post-route timing analysis or simulation is required to determine actual worst-case performance. Post-route timing is
based on actual routing delay measurements performed on the device prior to shipment.

CLKA/B
Clock A and B
TCK
Test Clock
These pins are 3.3V/5.0V PCI/TTL clock inputs for clock
distribution networks. The clock input is buffered prior to
clocking the R-cells. If not used, this pin must be set LOW or
HIGH on the board. It must not be left floating. (For
A54SX72A, these clocks can be configured as bidirectional.)
Test clock input for diagnostic probe and device
programming. In flexible mode, TCK becomes active when
the TMS pin is set LOW (refer to Table 2 on page 8). This pin
functions as an I/O when the boundary scan state machine
reaches the “logic reset” state.
GND
TDI
Ground
LOW supply voltage.
HCLK
Dedicated (Hard-wired)
Array Clock
This pin is the 3.3V/5.0V PCI/TTL clock input for sequential
modules. This input is directly wired to each R-cell and
offers clock speeds independent of the number of R-cells
being driven. If not used, this pin must be set LOW or HIGH
on the board. It must not be left floating.
I/O
Input/Output
The I/O pin functions as an input, output, tristate, or
bidirectional buffer. Based on certain configurations, input
and output levels are compatible with standard TTL, LVTTL,
3.3V PCI or 5.0V PCI specifications. Unused I/O pins are
automatically tristated by the Designer Series software.
NC
No Connection
This pin is not connected to circuitry within the device.
PRA, I/O
Probe A
The Probe A pin is used to output data from any
user-defined design node within the device. This
independent diagnostic pin can be used in conjunction with
the Probe B pin to allow real-time diagnostic output of any
signal path within the device. The Probe A pin can be used
as a user-defined I/O when verification has been completed.
The pin’s probe capabilities can be permanently disabled to
protect programmed design confidentiality.
PRB, I/O
Probe B
The Probe B pin is used to output data from any node within
the device. This diagnostic pin can be used in conjunction
with the Probe A pin to allow real-time diagnostic output of
any signal path within the device. The Probe B pin can be
used as a user-defined I/O when verification has been
completed. The pin’s probe capabilities can be permanently
disabled to protect programmed design confidentiality.
34
Test Data Input
Serial input for boundary scan testing and diagnostic probe.
In flexible mode, TDI is active when the TMS pin is set LOW
(refer to Table 2 on page 8). This pin functions as an I/O
when the boundary scan state machine reaches the “logic
reset” state.
TDO
Test Data Output
Serial output for boundary scan testing. In flexible mode,
TDO is active when the TMS pin is set LOW (refer to Table 2
on page 8). This pin functions as an I/O when the boundary
scan state machine reaches the “logic reset” state.
TMS
Test Mode Select
The TMS pin controls the use of the IEEE 1149.1 Boundary
Scan pins (TCK, TDI, TDO). In flexible mode when the TMS
pin is set LOW, the TCK, TDI, and TDO pins are boundary
scan pins (refer to Table 2 on page 8). Once the boundary
scan pins are in test mode, they will remain in that mode
until the internal boundary scan state machine reaches the
“logic reset” state. At this point, the boundary scan pins will
be released and will function as regular I/O pins. The “logic
reset” state is reached 5 TCK cycles after the TMS pin is set
HIGH. In dedicated test mode, TMS functions as specified in
the IEEE 1149.1 specifications.
V CCI
Supply Voltage
Supply voltage for I/Os. See Table 1 on page 8.
V CCA

Supply voltage for Array. See Table 1 on page 8.
V CCR

In order to provide the latest information to designers, some datasheets are published before data has been fully
characterized. Datasheets are designated as “Product Brief,” “Advanced,” “Production.” The definition of these categories
are as follows:
Product Brief
The product brief is a modified version of an advanced datasheet containing general product information. This brief
summarizes specific device and family information for unreleased products.
A d v an ce d
This datasheet version contains initial estimated information based on simulation, other products, devices, or speed grades.
This information can be used as estimates but not for production.
U n ma r k ed ( pr o d uc t io n )
This datasheet version contains information that is considered to be final.
