Revision 3
1 – ACT 3 Family Overview
General Description
Microsemi’s ACT 3 Accelerator Series of FPGAs offers the industry’s fastest high-capacity
programmable logic device. ACT 3 FPGAs offer a high performance, PCI compliant programmable
solution capable of 186 MHz on-chip performance and 9.0 nanosecond clock-to-output (–1 speed grade),
with capacities spanning from 1,500 to 10,000 gate array equivalent gates.
The ACT 3 family builds on the proven two-module architecture consisting of combinatorial and
sequential logic modules used in Microsemi’s 3200DX and 1200XL families. In addition, the ACT 3 I/O
modules contain registers which deliver 9.0 nanosecond clock-to-out times (–1 speed grade). The
devices contain four clock distribution networks, including dedicated array and I/O clocks, supporting
very fast synchronous and asynchronous designs. In addition, routed clocks can be used to drive high
fanout signals such as flip-flop resets and output.
The ACT 3 family is supported by Microsemi’s Designer Series Development System which offers
automatic placement and routing (with automatic or fixed pin assignments), static timing analysis, user
programming, and debug and diagnostic probe capabilities.

2 – Detailed Specifications
This section of the datasheet is meant to familiarize the user with the architecture of the ACT 3 family of
FPGA devices. A generic description of the family will be presented first, followed by a detailed
description of the logic blocks, the routing structure, the antifuses, and the special function circuits. The
on-chip circuitry required to program the devices is not covered.
Topology
The ACT 3 family architecture is composed of six key elements: Logic modules, I/O modules, I/O Pad
Drivers, Routing Tracks, Clock Networks, and Programming and Test Circuits. The basic structure is
similar for all devices in the family, differing only in the number of rows, columns, and I/Os. The array
itself consists of alternating rows of modules and channels. The logic modules and channels are in the
center of the array; the I/O modules are located along the array periphery. A simplified floor plan is
depicted in Figure 2-1.

Logic Modules
ACT 3 logic modules are enhanced versions of the 1200XL family logic modules. As in the 1200XL
family, there are two types of modules: C-modules and S-modules (Figure 2-2 and Figure 2-3). The Cmodule is functionally equivalent to the 1200XL C-module and implements high fanin combinatorial
macros, such as 5-input AND, 5-input OR, and so on. It is available for use as the CM8 hard macro. The
S-module is designed to implement high-speed sequential functions within a single module.

S-Module Diagram
S-modules consist of a full C-module driving a flip-flop, which allows an additional level of logic to be
implemented without additional propagation delay. It is available for use as the DFM8A/B and DLM8A/B
hard macros. C-modules and S-modules are arranged in pairs called module-pairs. Module-pairs are
arranged in alternating patterns and make up the bulk of the array. This arrangement allows the
placement software to support two-module macros of four types (CC, CS, SC, and SS). The C-module
implements the following function:
Y = !S1 * !S0 * D00 + !S1 * S0 * D01 + S1 * !S0 * D10 + S1 * S0 * D11
EQ 1
where: S0 = A0 * B0 and S1 = A1 + B1
2-2
R e vi s i o n 3
Accelerator Series FPGAs – ACT 3 Family
The S-module contains a full implementation of the C-module plus a clearable sequential element that
can either implement a latch or flip-flop function. The S-module can therefore implement any function
implemented by the C-module. This allows complex combinatorial-sequential functions to be
implemented with no delay penalty. The Designer Series Development System will automatically
combine any C-module macro driving an S-module macro into the S-module, thereby freeing up a logic
module and eliminating a module delay.
The clear input CLR is accessible from the routing channel. In addition, the clock input may be connected
to one of three clock networks: CLKA, CLKB, or HCLK. The C-module and S-module functional
descriptions are shown in Figure 2-2 and Figure 2-3 on page 2-2. The clock selection is determined by a
multiplexer select at the clock input to the S-module.
I/Os
I/O Modules
I/O modules provide an interface between the array and the I/O Pad Drivers. I/O modules are located in
the array and access the routing channels in a similar fashion to logic modules. The I/O module
schematic is shown in Figure 4. The signals DataIn and DataOut connect to the I/O pad driver.

Functional Diagram for I/O Module
Each I/O module contains two D-type flip-flops. Each flip-flop is connected to the dedicated I/O clock
(IOCLK). Each flip-flop can be bypassed by nonsequential I/Os. In addition, each flip-flop contains a data
enable input that can be accessed from the routing channels (ODE and IDE). The asynchronous
preset/clear input is driven by the dedicated preset/clear network (IOPCL). Either preset or clear can be
selected individually on an I/O module by I/O module basis.
Revision 3
2 -3
Detailed Specifications
The I/O module output Y is used to bring Pad signals into the array or to feed the output register back into
the array. This allows the output register to be used in high-speed state machine applications. Side I/O
modules have a dedicated output segment for Y extending into the routing channels above and below
(similar to logic modules). Top/Bottom I/O modules have no dedicated output segment. Signals coming
into the chip from the top or bottom are routed using F-fuses and LVTs (F-fuses and LVTs are explained
in detail in the routing section).
I/O Pad Drivers
All pad drivers are capable of being tristate. Each buffer connects to an associated I/O module with four
signals: OE (Output Enable), IE (Input Enable), DataOut, and DataIn. Certain special signals used only
during programming and test also connect to the pad drivers: OUTEN (global output enable), INEN
(global input enable), and SLEW (individual slew selection). See Figure 2-5.

Special I/Os
The special I/Os are of two types: temporary and permanent. Temporary special I/Os are used during
programming and testing. They function as normal I/Os when the MODE pin is inactive. Permanent
special I/Os are user programmed as either normal I/Os or special I/Os. Their function does not change
once the device has been programmed. The permanent special I/Os consist of the array clock input
buffers (CLKA and CLKB), the hard-wired array clock input buffer (HCLK), the hard-wired I/O clock input
buffer (IOCLK), and the hard-wired I/O register preset/clear input buffer (IOPCL). Their function is
determined by the I/O macros selected.
Clock Networks
The ACT 3 architecture contains four clock networks: two high-performance dedicated clock networks
and two general purpose routed networks. The high-performance networks function up to 200 MHz,
while the general purpose routed networks function up to 150 MHz.

Dedicated Clocks
Dedicated clock networks support high performance by providing sub-nanosecond skew and guaranteed
performance. Dedicated clock networks contain no programming elements in the path from the I/O Pad
Driver to the input of S-modules or I/O modules. There are two dedicated clock networks: one for the
array registers (HCLK), and one for the I/O registers (IOCLK). The clock networks are accessed by
special I/Os.

Clock Networks
The routed clock networks are referred to as CLK0 and CLK1. Each network is connected to a clock
module (CLKMOD) that selects the source of the clock signal and may be driven as follows (Figure 2-6):
•
Externally from the CLKA pad
•
Externally from the CLKB pad
•
Internally from the CLKINA input
•
Internally from the CLKINB input
The clock modules are located in the top row of I/O modules. Clock drivers and a dedicated horizontal
clock track are located in each horizontal routing channel. The function of the clock module is determined
by the selection of clock macros from the macro library. The macro CLKBUF is used to connect one of
the two external clock pins to a clock network, and the macro CLKINT is used to connect an internally
generated clock signal to a clock network. Since both clock networks are identical, the user does not care
whether CLK0 or CLK1 is being used. Routed clocks can also be used to drive high fanout nets like
resets, output enables, or data enables. This saves logic modules and results in performance increases
in some cases.
Routing Structure
The ACT 3 architecture uses vertical and horizontal routing tracks to connect the various logic and I/O
modules. These routing tracks are metal interconnects that may either be of continuous length or broken
into segments. Segments can be joined together at the ends using antifuses to increase their lengths up
to the full length of the track.
Revision 3

Detailed Specifications
Horizontal Routing
Horizontal channels are located between the rows of modules and are composed of several routing
tracks. The horizontal routing tracks within the channel are divided into one or more segments. The
minimum horizontal segment length is the width of a module-pair, and the maximum horizontal segment
length is the full length of the channel. Any segment that spans more than one-third the row length is
considered a long horizontal segment. A typical channel is shown in Figure 2-7. Undedicated horizontal
routing tracks are used to route signal nets. Dedicated routing tracks are used for the global clock
networks and for power and ground tie-off tracks.

Vertical Routing
Other tracks run vertically through the modules. Vertical tracks are of three types: input, output, and long.
Vertical tracks are also divided into one or more segments. Each segment in an input track is dedicated
to the input of a particular module. Each segment in an output track is dedicated to the output of a
particular module. Long segments are uncommitted and can be assigned during routing. Each output
segment spans four channels (two above and two below), except near the top and bottom of the array
where edge effects occur. LVTs contain either one or two segments. An example of vertical routing tracks
and segments is shown in Figure 2-8.

Antifuse Connections
An antifuse is a “normally open” structure as opposed to the normally closed fuse structure used in
PROMs or PALs. The use of antifuses to implement a programmable logic device results in highly
testable structures as well as an efficient programming architecture. The structure is highly testable
because there are no preexisting connections; temporary connections can be made using pass
transistors. These temporary connections can isolate individual antifuses to be programmed as well as
isolate individual circuit structures to be tested. This can be done both before and after programming. For
example, all metal tracks can be tested for continuity and shorts between adjacent tracks, and the
functionality of all logic modules can be verified.
Four types of antifuse connections are used in the routing structure of the ACT 3 array. (The physical
structure of the antifuse is identical in each case; only the usage differs.)
Table 2-1 shows four types of antifuses.
Table 2-1 • Antifuse Types

Description

HF

VF

FF
"Fast" vertical connection
Examples of all four types of connections are shown in Figure 2-7 on page 2-6 and Figure 2-8 on
page 2-6.
Module Interface
Connections to Logic and I/O modules are made through vertical segments that connect to the module
inputs and outputs. These vertical segments lie on vertical tracks that span the entire height of the array.
Module Input Connections
The tracks dedicated to module inputs are segmented by pass transistors in each module row. During
normal user operation, the pass transistors are inactive, which isolates the inputs of a module from the
inputs of the module directly above or below it. During certain test modes, the pass transistors are active
to verify the continuity of the metal tracks. Vertical input segments span only the channel above or the
channel below. The logic modules are arranged such that half of the inputs are connected to the channel
above and half of the inputs to segments in the channel below, as shown in Figure 2-9.

Detailed Specifications
Module Output Connections
Module outputs have dedicated output segments. Output segments extend vertically two channels above
and two channels below, except at the top or bottom of the array. Output segments twist, as shown in
Figure 10, so that only four vertical tracks are required.
LVT Connections
Outputs may also connect to nondedicated segments called Long Vertical Tracks (LVTs). Each module
pair in the array shares four LVTs that span the length of the column. Any module in the column pair can
connect to one of the LVTs in the column using an FF connection. The FF connection uses antifuses
connected directly to the driver stage of the module output, bypassing the isolation transistor. FF
antifuses are programmed at a higher current level than HF, VF, or XF antifuses to produce a lower
resistance value.
Antifuse Connections
In general every intersection of a vertical segment and a horizontal segment contains an unprogrammed
antifuse (XF-type). One exception is in the case of the clock networks.
Clock Connections
To minimize loading on the clock networks, a subset of inputs has antifuses on the clock tracks. Only a
few of the C-module and S-module inputs can be connected to the clock networks. To further reduce
loading on the clock network, only a subset of the horizontal routing tracks can connect to the clock
inputs of the S-module.
Programming and Test Circuits
The array of logic and I/O modules is surrounded by test and programming circuits controlled by the
temporary special I/O pins MODE, SDI, and DCLK. The function of these pins is similar to all ACT family
devices. The ACT 3 family also includes support for two Actionprobe® circuits, allowing complete
observability of any logic or I/O module in the array using the temporary special I/O pins, PRA and PRB.

Power Dissipation
P = [ICC standby + Iactive] * VCC * IOL * VOL * N + IOH* (VCC – VOH) * M
EQ 3
where:
ICC standby is the current flowing when no inputs or outputs are changing
Iactive is the current flowing due to CMOS switching.
IOL and IOH are TTL sink/source current.
VOL and VOH are TTL level output voltages.
N is the number of outputs driving TTL loads to VOL.
M equals the number of outputs driving TTL loads to VOH.
An accurate determination of N and M is problematical because their values depend on the design and
on the system I/O. The power can be divided into two components: static and active.
Static Power Component
Microsemi FPGAs have small static power components that result in lower power dissipation than PALs
or PLDs. By integrating multiple PALs/PLDs into one FPGA, an even greater reduction in board-level
power dissipation can be achieved.
The power due to standby current is typically a small component of the overall power. Standby power is
calculated in Table 2-9 for commercial, worst case conditions.
Table 2-9 • Standby Power Calculation
ICC
2 mA
VCC
Power
5.25 V
10.5 mW
The static power dissipated by TTL loads depends on the number of outputs driving high or low and the
DC load current. Again, this value is typically small. For instance, a 32-bit bus sinking 4 mA at 0.33 V will
generate 42 mW with all outputs driving low, and 140 mW with all outputs driving high. The actual
dissipation will average somewhere between as I/Os switch states with time.
Active Power Component
Power dissipation in CMOS devices is usually dominated by the active (dynamic) power dissipation. This
component is frequency dependent, a function of the logic and the external I/O. Active power dissipation
results from charging internal chip capacitances of the interconnect, unprogrammed antifuses, module
inputs, and module outputs, plus external capacitance due to PC board traces and load device inputs.
An additional component of the active power dissipation is the totem-pole current in CMOS transistor
pairs. The net effect can be associated with an equivalent capacitance that can be combined with
frequency and voltage to represent active power dissipation.
Equivalent Capacitance
The power dissipated by a CMOS circuit can be expressed by EQ 4.
Power (µW) = CEQ * VCC2 * F
EQ 4
Where:
CEQ is the equivalent capacitance expressed in pF.
VCC is the power supply in volts.
F is the switching frequency in MHz.
2- 12
R e visio n 3
Accelerator Series FPGAs – ACT 3 Family
Equivalent capacitance is calculated by measuring ICC active at a specified frequency and voltage for
each circuit component of interest. Measurements have been made over a range of frequencies at a
fixed value of VCC. Equivalent capacitance is frequency independent so that the results may be used
over a wide range of operating conditions. Equivalent capacitance values are shown in Figure 2-10.

Determining Average Switching Frequency
To determine the switching frequency for a design, you must have a detailed understanding of the data
input values to the circuit. The following guidelines are meant to represent worst-case scenarios so that
they can be generally used to predict the upper limits of power dissipation. These guidelines are as
follows:

Tightest Delay Distributions
Propagation delay between logic modules depends on the resistive and capacitive loading of the routing
tracks, the interconnect elements, and the module inputs being driven. Propagation delay increases as
the length of routing tracks, the number of interconnect elements, or the number of inputs increases.
From a design perspective, the propagation delay can be statistically correlated or modeled by the fanout
(number of loads) driven by a module. Higher fanout usually requires some paths to have longer lengths
of routing track. The ACT 3 family delivers the tightest fanout delay distribution of any FPGA. This tight
distribution is achieved in two ways: by decreasing the delay of the interconnect elements and by
decreasing the number of interconnect elements per path.
Microsemi’s patented PLICE antifuse offers a very low resistive/capacitive interconnect. The ACT 3
family’s antifuses, fabricated in 0.8 micron m lithography, offer nominal levels of 200Ω resistance and 6
femtofarad (fF) capacitance per antifuse. The ACT 3 fanout distribution is also tighter than alternative
devices due to the low number of antifuses required per interconnect path. The ACT 3 family’s
proprietary architecture limits the number of antifuses per path to only four, with 90% of interconnects
using only two antifuses.
The ACT 3 family’s tight fanout delay distribution offers an FPGA design environment in which fanout can
be traded for the increased performance of reduced logic level designs. This also simplifies performance
estimates when designing with ACT 3 devices.

Timing Characteristics
Timing characteristics for ACT 3 devices fall into three categories: family dependent, device dependent,
and design dependent. The input and output buffer characteristics are common to all ACT 3 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 ALS Timer utility or performing simulation with post-layout delays.
Critical Nets and Typical Nets
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.
Long Tracks
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 four antifuse connections. This
increases capacitance and resistance, result ng 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 14 ns delay. This additional delay is represented statistically in higher fanout
(FO = 8) routing delays in the datasheet specifications section.

Timing Derating
ACT 3 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.

3. The –2 and –3 speed grades have been discontinued. Refer to PDN 0104, PDN 0203, PDN 0604, and PDN 1004 at
http://www.microsemi.com/soc/support/notifications/default.aspx#pdn.
4. 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.

3. The –2 and –3 speed grades have been discontinued. Refer to PDN 0104, PDN 0203, PDN 0604, and PDN 1004 at
http://www.microsemi.com/soc/support/notifications/default.aspx#pdn.
4. 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.

Detailed Specifications
Pin Descriptions
CLKA
Clock A (Input)
Clock input for clock distribution networks. The Clock input is buffered prior to clocking the logic modules.
This pin can also be used as an I/O.
CLKB
Clock B (Input)
Clock input for clock distribution networks. The Clock input is buffered prior to clocking the logic modules.
This pin can also be used as an I/O.
GND
Ground
LOW supply voltage.
HCLK
Dedicated (Hard-wired)
Array Clock (Input)
Clock input for sequential modules. This input is directly wired to each S-Module and offers clock speeds
independent of the number of S-Modules being driven. This pin can also be used as an I/O.
I/O
Input/Output (Input, Output)
The I/O pin functions as an input, output, three-state, or bidirectional buffer. Input and output levels are
compatible with standard TTL and CMOS specifications. Unused I/O pins are tristated by the Designer
Series software.
IOCLK
Dedicated (Hard-wired)
I/O Clock (Input)
Clock input for I/O modules. This input is directly wired to each I/O module and offers clock speeds
independent of the number of I/O modules being driven. This pin can also be used as an I/O.
IOPCL
Dedicated (Hard-wired)
I/O Preset/Clear (Input)
Input for I/O preset or clear. This global input is directly wired to the preset and clear inputs of all I/O
registers. This pin functions as an I/O when no I/O preset or clear macros are used.
MODE
Mode (Input)
The MODE pin controls the use of diagnostic pins (DCLK, PRA, PRB, SDI). When the MODE pin is
HIGH, the special functions are active. When the MODE pin is LOW, the pins function as I/Os. To provide
Actionprobe capability, the MODE pin should be terminated to GND through a 10K resistor so that the
MODE pin can be pulled high when required.
NC
No Connection
This pin is not connected to circuitry within the device.
PRA
Probe A (Output)
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
debugging has been completed. The pin’s probe capabilities can be permanently disabled to protect
programmed design confidentiality. PRA is accessible when the MODE pin is HIGH. This pin functions as
an I/O when the MODE pin is LOW.
PRB
Probe B (Output)
The Probe B 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 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
debugging has been completed. The pin’s probe capabilities can be permanently disabled to protect
programmed design confidentiality. PRB is accessible when the MODE pin is HIGH. This pin functions as
an I/O when the MODE pin is LOW.
SDI
Serial Data Input (Input)
Serial data input for diagnostic probe and device programming. SDI is active when the MODE pin is
HIGH. This pin functions as an I/O when the MODE pin is LOW.

Datasheet Categories
Categories
In order to provide the latest information to designers, some datasheet parameters are published before
data has been fully characterized from silicon devices. The data provided for a given device is
designated as either "Product Brief," "Advance," "Preliminary," or "Production." The definitions of these
categories are as follows:
Product Brief
The product brief is a summarized version of a datasheet (advance or production) and contains general
product information. This document gives an overview of specific device and family information.
Advance
This 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. This label only applies to the
DC and Switching Characteristics chapter of the datasheet and will only be used when the data has not
been fully characterized.
Preliminary
The datasheet contains information based on simulation and/or initial characterization. The information is
believed to be correct, but changes are possible.
Production
This version contains information that is considered to be final.
