The ACTTM 2 family represents Actel's second generation of
field programmable gate arrays (FPGAs). The ACT 2 family
presents a two-module architecture, consisting of C-modules
and S-modules. These modules are optimized for both
combinatorial and sequential designs. Based on Actel's
patented channeled array architecture, the ACT 2 family
provides significant enhancements to gate density and
performance while maintaining downward compatibility
with the ACT 1 design environment and upward
compatibility with the ACT 3 design environment. The
devices are implemented in silicon gate, 1.0-m, two-level
metal CMOS, and employ Actel's PLICE
antifuse
technology. This revolutionary architecture offers gate array
design flexibility, high performance, and fast
time-to-production with user programming. The ACT 2
family is supported by the Designer and Designer Advantage
Systems, which offers automatic pin assignment, validation
of electrical and design rules, automatic placement and
routing, timing analysis, user programming, and diagnostic
probe capabilities. The systems are supported on the
following platforms: 386/486TM PC, Sun
TM
, and HP
TM
workstations. The systems provide CAE interfaces to the
following design environments: Cadence, Viewlogic
,
Mentor Graphics
, and OrCADTM.

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.
Device inputs are normally high impedance and draw
extremely low current. However, when input voltage is greater
than V
CC
+ 0.5 V or less than GND 0.5 V, the internal
protection diode will be forward biased and can draw excessive
current.

The device junction to case thermal characteristic is
jc,
and the junction to ambient air characteristic is
ja. The
thermal characteristics for
ja are shown with two different
air flow rates.
Maximum junction temperature is 150C.
A sample calculation of the absolute maximum power
dissipation allowed for a PQFP 160-pin package at
commercial temperature is as follows:
P o w e r D i s s i p a t i o n
P = [I
CC
standby + I
CC
active] * V
CC
+ I
OL
* V
OL
* N +
I
OH
* (V
CC
V
OH
) * M
Where:
I
CC
standby is the current flowing when no inputs or outputs
are changing.
I
CC
active is the current flowing due to CMOS switching.
I
OL
, I
OH
are TTL sink/source currents.
V
OL
, V
OH
are TTL level output voltages.
N equals the number of outputs driving TTL loads to V
OL
.
M equals the number of outputs driving TTL loads to V
OH
.
An accurate determination of N and M is problematical
because their values depend on the family type, design
details, and on the system I/O. The power can be divided
into two components: static and active.
S ta t i c P o w e r C o m p o n e n t
Actel 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 below for commercial, worst case conditions.
I

Power
2 mA
5.25V
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.
A c ti v e P o w e r C o m p o n e n t
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
