Spartan-6 FPGA Electrical Characteristics
Spartan®-6 LX and LXT FPGAs are available in various speed grades, with -3 having the highest performance. The DC and
AC electrical parameters of the Automotive XA Spartan-6 FPGAs and Defense-grade Spartan-6Q FPGAs devices are
equivalent to the commercial specifications except where noted. The timing characteristics of the commercial (XC) -2 speed
grade industrial device are the same as for a -2 speed grade commercial device. The -2Q and -3Q speed grades are
exclusively for the expanded (Q) temperature range. The timing characteristics are equivalent to those shown for the -2 and
-3 speed grades for the Automotive and Defense-grade devices.
Spartan-6 FPGA DC and AC characteristics are specified for commercial (C), industrial (I), and expanded (Q) temperature
ranges. Only selected speed grades and/or devices might be available in the industrial or expanded temperature ranges for
Automotive and Defense-grade devices. References to device names refer to all available variations of that part number (for
example, LX75 could denote XC6SLX75, XA6SLX75, or XQ6SLX75).The Spartan-6 FPGA -3N speed grade designates
devices that do not support MCB functionality.
All supply voltage and junction temperature specifications are representative of worst-case conditions. The parameters
included are common to popular designs and typical applications.

Notes:
1. Typical values are specified at nominal voltage, 25°C junction temperatures (Tj). Industrial (I) grade devices have the same typical values as
commercial (C) grade devices at 25°C, but higher values at 100°C. Use the XPE tool to calculate 100°C values. Nominal VCCINT is 1.20V;
use the XPE tool to calculate 1.23V values for the nominal VCCINT of the extended performance range.
2. Typical values are for blank configured devices with no output current loads, no active input pull-up resistors, all I/O pins are 3-state and
floating.
3. If differential signaling is used, more accurate quiescent current estimates can be obtained by using the XPOWER Estimator (XPE) or
XPOWER Analyzer (XPA) tools.

VCCO2(1) Output drivers bank 2 supply voltage ramp time All 0.20 to 50.0 ms
VCCAUXR Auxiliary supply voltage ramp time All 0.20 to 50.0 ms
Notes:
1. The minimum VCCO2 for power-on reset and configuration is 1.65V.
2. Spartan-6 FPGAs require a certain amount of supply current during power-on to insure proper device initialization. The actual current
consumed depends on the power-on ramp rate of the power supply. Use the XPOWER Estimator (XPE) or XPOWER Analyzer (XPA) tools
to estimate current drain on these supplies. Spartan-6 devices do not have a required power-on sequence.

Spartan-6 FPGA Data Sheet: DC and Switching Characteristics

Product Specification 19
Switching Characteristics
All values represented in this data sheet are based on these
speed specifications: v1.20 for -3, -3N, and -2; and v1.08 for
-1L. Switching characteristics are specified on a per-speed-
grade basis and can be designated as Advance,
Preliminary, or Production. Each designation is defined as
follows:
Advance
These specifications are based on simulations only and are
typically available soon after device design specifications
are frozen. Although speed grades with this designation are
considered relatively stable and conservative, some under-
reporting might still occur.
Preliminary
These specifications are based on complete ES
(engineering sample) silicon characterization. Devices and
speed grades with this designation are intended to give a
better indication of the expected performance of production
silicon. The probability of under-reporting delays is greatly
reduced as compared to Advance data.
Production
These specifications are released once enough production
silicon of a particular device family member has been
characterized to provide full correlation between
specifications and devices over numerous production lots.
There is no under-reporting of delays, and customers
receive formal notification of any subsequent changes.
Typically, the slowest speed grades transition to Production
before faster speed grades.
All specifications are always representative of worst-case
supply voltage and junction temperature conditions.
Since individual family members are produced at different
times, the migration from one category to another depends
completely on the status of the fabrication process for each
device.
The -1L speed grade refers to the lower-power Spartan-6
devices. The -3N speed grade refers to the Spartan-6
devices that do not support MCB functionality.
Ta bl e 2 6 correlates the current status of each Spartan-6
device on a per speed grade basis.
Testing of Switching Characteristics
All devices are 100% functionally tested. Internal timing parameters are derived from measuring internal test patterns. Listed
below are representative values.
For more specific, more precise, and worst-case guaranteed data, use the values reported by the static timing analyzer and
back-annotate to the simulation net list. Unless otherwise noted, values apply to all Spartan-6 devices.

Production Silicon and ISE Software Status
In some cases, a particular family member (and speed grade) is released to production before a speed specification is
released with the correct label (Advance, Preliminary, Production). Any labeling discrepancies are corrected in subsequent
speed specification releases. Ta b l e 2 7 lists the production released Spartan-6 family member, speed grade, and the
minimum corresponding supported speed specification version and ISE® software revisions. The ISE software and speed
specifications listed are the minimum releases required for production. All subsequent releases of software and speed
specifications are valid.

IOB Pad Input/Output/3-State Switching Characteristics
Ta bl e 2 8 (for commercial (XC) Spartan-6 devices) and Ta bl e 2 9 (for Automotive XA Spartan-6 and Defense-grade
Spartan-6Q devices) summarizes the values of standard-specific data input delays, output delays terminating at pads
(based on standard), and 3-state delays.
•T
IOPI is described as the delay from IOB pad through the input buffer to the I-pin of an IOB pad. The delay varies
depending on the capability of the SelectIO input buffer.
•T
IOOP is described as the delay from the O pin to the IOB pad through the output buffer of an IOB pad. The delay varies
depending on the capability of the SelectIO output buffer.
•T
IOTP is described as the delay from the T pin to the IOB pad through the output buffer of an IOB pad, when 3-state is
disabled. The delay varies depending on the SelectIO capability of the output buffer.
See the TRACE report for further information on delays when using an I/O standard with UNTUNED termination on inputs
or outputs.

Output Delay Measurements
Output delays are measured using a Tektronix P6245
TDS500/600 probe (< 1 pF) across approximately 4" of FR4
microstrip trace. Standard termination was used for all
testing. The propagation delay of the 4" trace is
characterized separately and subtracted from the final
measurement, and is therefore not included in the
generalized test setups shown in Figure 4 and Figure 5.
Measurements and test conditions are reflected in the IBIS
models except where the IBIS format precludes it.
Parameters VREF, RREF, CREF, and VMEAS fully describe
the test conditions for each I/O standard. The most accurate
prediction of propagation delay in any given application can
be obtained through IBIS simulation, using the following
method:
1. Simulate the output driver of choice into the generalized
test setup, using values from Ta b l e 3 2 .
2. Record the time to VMEAS.
3. Simulate the output driver of choice into the actual PCB
trace and load, using the appropriate IBIS model or
capacitance value to represent the load.
4. Record the time to VMEAS.
5. Compare the results of steps 2 and 4. The increase or
decrease in delay yields the actual propagation delay of
the PCB trace.

Simultaneously Switching Outputs
Due to package electrical parasitics, a given package supports a limited number of simultaneous switching outputs (SSOs)
when using fast, high-drive outputs. Ta bl e 3 3 and Ta b l e 3 4 provide guidelines for the recommended maximum allowable
number of SSOs. These guidelines describe the maximum number of user I/O pins of an output signal standard that should
simultaneously switch in the same direction, while maintaining a safe level of switching noise for that particular signal
standard. Meeting these guidelines for the stated test conditions ensures that the FPGA operates free from the adverse
effects of GND and power bounce.
For each device/package combination, Ta bl e 3 3 provides the number of equivalent VCCO/GND pairs per bank. For each
output signal standard and drive strength, Ta bl e 3 4 recommends the maximum number of SSOs, switching in the same
direction, allowed per VCCO/GND pair within an I/O bank. The guidelines are categorized by package style, slew rate, and
output drive current. The number of SSOs are also specified by I/O bank. Multiply the appropriate numbers from each table
to calculate the maximum number of SSOs allowed within an I/O bank. The guidelines assume that all pins within a bank use
the same I/O standard. Exceeding these SSO guidelines can result in increased power or GND bounce, degraded signal
integrity, or increased system jitter. For a given I/O standard, if the SSO limit per pair in Ta b le 3 4 is greater than the maximum
I/O per pair in Ta bl e 3 3 , then there is no SSO limit for the exclusive use of that I/O standard.
The recommended maximum SSO values assume that the FPGA is soldered on a printed circuit board and that the board
uses sound design practices. Due to the additional inductance introduced by the socket, the SSO values do not apply for
FPGAs mounted in sockets. The SSO values assume that the VCCAUX is powered at 3.3V. Setting VCCAUX to 2.5V provides
better SSO characteristics. For more detail, see UG381: Spartan-6 FPGA SelectIO Resources User Guide.

Notes:
1. SSO limits greater than the number of I/O per VCCO/GND pair (Ta bl e 3 3 ) indicate No Limit for the given I/O standard. They are provided in
this table to calculate limits when using multiple I/O standards in a bank.
2. Not available (N/A) indicates that the I/O standard is not available in the given bank.
3. When used with the MCB, these signals are exempt from SSO analysis due to the known activity of the MCB switching patterns. SSO
performance is validated for all MCB instances. MCB outputs can, in some cases, exceed the SSO limits.

Notes:
1. Delay depends on IODELAY2 tap setting. See TRACE report for actual values.
2. Maximum delay = integer (number of taps/8) TTA P 8 +T
TAP n (where n equals the remainder). For minimum delay consult the TRACE setup
and hold report. Minimum delay is typically greater than 30% of the maximum delay. Tap delays can vary by device and overall conditions.
See TRACE report for actual values.
3. Spartan-6 -1L devices only support tap 0. See TRACE report for actual values.

Notes:
1. DLL specifications apply when using any of the DLL outputs: CLK0, CLK90, CLK180, CLK270, CLK2X, CLK2X180, or CLKDV.
2. When operating independently of the DLL, the DFS supports lower CLKIN_FREQ_DLL frequencies. See Ta b l e 5 5 .
3. The CLKIN_DIVIDE_BY_2 attribute increases the effective input frequency range. When set to TRUE, the input clock frequency is divided by two as
it enters the DCM. Input clock frequencies for the clock buffer being used can be increased up to the FMAX (see Ta bl e 4 8 and Ta b l e 4 9 for BUFG and
BUFIO2 limits). When used with CLK_FEEDBACK=2X, the input clock frequency matches the frequency for CLK2X, and is limited to
CLKOUT_FREQ_2X.
4. CLKIN_FREQ_DLL input jitter beyond these limits can cause the DCM to lose LOCK, indicated by the LOCKED output deasserting. The user must
then reset the DCM.
5. When using both DCMs in a CMT, both DCMs must be LOCKED.

Notes:
1. The values in this table are based on the operating conditions described in Ta b l e 2 and Ta b l e 5 3 .
2. Indicates the maximum amount of output jitter that the DCM adds to the jitter on the CLKIN input.
3. For optimal jitter tolerance and faster LOCK time, use the CLKIN_PERIOD attribute.
4. Some jitter and duty-cycle specifications include 1% of input clock period or 0.01 UI. For example, this data sheet specifies a maximum jitter of
±(1% of CLKIN period + 150 ps). Assuming that the CLKIN frequency is 100 MHz, the equivalent CLKIN period is 10 ns. Since 1% of 10 ns is 0.1 ns
or 100 ps, the maximum jitter is ±(100 ps + 150 ps) = ±250 ps.
5. A typical delay step size is 23 ps.
6. The timing analysis tools use the CLK_FEEDBACK = 1X condition for the CLKIN_CLKFB_PHASE value (reported as phase error). When using
CLK_FEEDBACK = 2X, add 100 ps to the phase error for the CLKIN_CLKFB_PHASE value (as shown in this table).

Notes:
1. DFS specifications apply when using either of the DFS outputs (CLKFX or CLKFX180).
2. When using both DFS and DLL outputs on the same DCM, follow the more restrictive CLKIN_FREQ_DLL specifications in Ta b l e 5 3 .
3. The CLKIN_DIVIDE_BY_2 attribute increases the effective input frequency range. When set to TRUE, the input clock frequency is divided by two as
it enters the DCM. Input clock frequencies for the clock buffer being used can be increased up to the FMAX (see Ta bl e 4 8 and Table 4 9 for BUFG and
BUFIO2 limits).
4. CLKIN input jitter beyond these limits can cause the DCM to lose LOCK.

Notes:
1. The values in this table are based on the operating conditions described in Ta b l e 2 and Ta b l e 5 5 .
2. For optimal jitter tolerance and a faster LOCK time, use the CLKIN_PERIOD attribute.
3. Output jitter is characterized with no input jitter. Output jitter strongly depends on the environment, including the number of SSOs, the output drive
strength, CLB utilization, CLB switching activities, switching frequency, power supply, and PCB design. The actual maximum output jitter depends on
the system application.
4. The CLKFX, CLKFXDV, and CLKFX180 outputs have a duty cycle of approximately 50%.
5. Some duty cycle and alignment specifications include a percentage of the CLKFX output period. For example, this data sheet specifies a maximum
CLKFX jitter of ±(1% of CLKFX period + 200 ps). Assuming that the CLKFX output frequency is 100 MHz, the equivalent CLKFX period is 10 ns, and
1% of 10 ns is 0.1 ns or 100 ps. Accordingly, the maximum jitter is ±(100 ps + 200 ps) = ±300 ps.

Notes:
1. LXT devices are not available with a -1L speed grade. The LX4 is not available in -3N speed grade.
2. These parameters represent the worst-case duty cycle distortion observable at the pins of the device using LVDS output buffers. For cases where
other I/O standards are used, IBIS can be used to calculate any additional duty cycle distortion that might be caused by asymmetrical rise/fall times.
3. The TCKSKEW value represents the worst-case clock-tree skew observable between sequential I/O elements. Significantly less clock-tree skew exists
for I/O registers that are close to each other and fed by the same or adjacent clock-tree branches. Use the Xilinx FPGA Editor and Timing Analyzer
tools to evaluate clock skew specific to your application.
4. The TCKSKEW is 0.43 ns for the XA6SLX100 device using a -2 speed grade and 0.22 ns for the XC6SLX100 devices using the -2 speed grade.
