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 VCC + 0.5 V or less than GND - 0.5 V, the internal protection diode will be forward biased and can draw excessive current.

P = [ICCstandby + ICCactive] * VCC + IOL * VOL * N + IOH * (VCC - VOH) * M Where: ICC standby is the current flowing when no inputs or outputs are changing. ICC active is the current flowing due to CMOS switching. IOL, IOH are TTL sink/source currents. VOL, VOH are TTL level output voltages. N equals 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 family type, design details, and on the system I/O. The power can be divided into two components: static and active.

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. ICC 2 mA VCC 5.25V Power 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.
Ac ti ve P ower Com po nent
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
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.

= Fixed capacitance due to second routed array clock = Equivalent capacitance of logic modules in pF = Equivalent capacitance of input buffers in pF = Equivalent capacitance of output buffers in pF
The power dissipated by a CMOS circuit can be expressed by the Equation 1. Power (W) = CEQ * VCC2 * F Where: CEQ is the equivalent capacitance expressed in pF. VCC is the power supply in volts. F is the switching frequency in MHz. 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 below.

To calculate the active power dissipated from the complete design, the switching frequency of each part of the logic must be known. Equation 2 shows a piece-wise linear summation over all components. Power = VCC2 * [(m * CEQM* fm)modules +(n * CEQI* fn)inputs + (p * (CEQO+ CL) * fp)outputs + 0.5 * (q1 * CEQCR * fq1)routed_Clk1 + (r1 * fq1)routed_Clk1 + 0.5 * (q2 * CEQCR * fq2)routed_Clk2 (2) + (r2 * fq2)routed_Clk2] Where: m n p q1 q2 r1 = Number of logic modules switching at fm = Number of input buffers switching at fn = Number of output buffers switching at fp = Number of clock loads on the first routed array clock = Number of clock loads on the second routed array clock = Fixed capacitance due to first routed array clock
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: Logic Modules (m) Inputs switching (n) Outputs switching (p) First routed array clock loads (q1) 80% of modules # inputs/4 # outputs/4 40%of sequential modules 40%of sequential modules 35 pF F/10 F/5 F/10 F

Notes: 1. For dual-module macros, use tPD1 + tRD1 + tPDn , tCO + 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. 3. Data applies to macros based on the S-module. Timing parameters for sequential macros constructed from C-modules can be obtained from the DirectTime Analyzer utility. 4. Setup and hold timing parameters for the Input Buffer Latch are defined with respect to the PAD and the D input. External setup/hold timing parameters must account for delay from an external PAD signal to the G inputs. Delay from an external PAD signal to the G input subtracts (adds) to the internal setup (hold) time.

Notes: 1. For dual-module macros, use tPD1 + tRD1 + tPDn , tCO + 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. 3. Data applies to macros based on the S-module. Timing parameters for sequential macros constructed from C-modules can be obtained from the DirectTime Analyzer utility. 4. Setup and hold timing parameters for the Input Buffer Latch are defined with respect to the PAD and the D input. External setup/hold timing parameters must account for delay from an external PAD signal to the G inputs. Delay from an external PAD signal to the G input subtracts (adds) to the internal setup (hold) time.

CLKA Clock A (Input) PRA Probe A (Output)
TTL 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)
TTL 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.
DCLK Diagnostic Clock (Input)
TTL Clock input for diagnostic probe and device programming. DCLK is active when the MODE pin is HIGH. This pin functions as an I/O when the MODE pin is LOW.
GND Ground
The Probe A pin is used to output data from any user-defined design node within the device. This independent diagnostic pin is 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 active when the MODE pin is HIGH. This pin functions as an I/O when the MODE pin is LOW.
PRB Probe B (Output)
LOW supply voltage.
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 automatically driven LOW by the ALS software.
MODE Mode (Input)
The Probe B pin is used to output data from any user-defined design node within the device. This independent diagnostic pin is 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 active when the MODE pin is HIGH. This pin functions as an I/O when the MODE pin is LOW.
SDI Serial Data Input (Input)
The MODE pin controls the use of multifunction 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
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.
V CC 5.0V Supply Voltage

In order to provide the latest information to designers, some data sheets are published before data has been fully characterized. These data sheets are marked as "Advanced" or Preliminary" data sheets. The definition of these categories are as follows:
Adv anc ed
The data sheet contains initial estimated information based on simulation, other products, devices, or speed grades. This information can be used as estimates, but not for production.
P rel im i nar y
The data sheet contains information based on simulation and/or initial characterization. The information is believed to be correct, but changes are possible.
Unm ar ked (pr odu ct ion)
The data sheet contains information that is considered to be final.
