XC4000XL Electrical Specifications
Definition of Terms
In the following tables, some specifications may be designated as Advance or Preliminary. These terms are defined as
follows:
Advance:
Initial estimates based on simulation and/or extrapolation from other speed grades, devices, or
devicefamilies. Values are subject to change. Use as estimates, not for production.
Preliminary:
Based on preliminary characterization. Further changes are not expected.
Unmarked:
Specifications not identified as either Advance or Preliminary are to be considered Final.
Except for pin-to-pin input and output parameters, the a.c. parameter delay specifications included in this document are
derived from measuring internal test patterns. All specifications are representative of worst-case supply voltage and junction
temperature conditions.
All specifications subject to change without notice.

undershoot lasts less than 10 ns and with the forcing current being limited to 200 mA.
Note:
Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are
stress ratings only, and functional operation of the device at these or any other conditions beyond those listed under
Recommended Operating Conditions is not implied. Exposure to Absolute Maximum Ratings conditions for extended
periods of time may affect device reliability.

D.C. Characteristics Over Recommended Operating Conditions
Power-0n Power Supply Requirements
Xilinx FPGAs require a minimum rated power supply current capacity to insure proper initialization, and the power supply
ramp-up time does affect the current required. A fast ramp-up time requires more current than a slow ramp-up time. The
slowest ramp-up time is 50 ms. Current capacity is not specified for a ramp-up time faster than 2ms. The current capacity
varies linealy with ramp-up time,
e.g., an XC4036XL with a ramp-up time of 25 ms would require a capacity predicted by the
point on the straight line drawn from 1A at 120
s to 500 mA at 50 ms at the 25 ms time mark. This point is approximately
750 mA
.

Notes:

The XC4085XL fast ramp-up time is 5 ms.
Devices are guaranteed to initialize properly with the minimum current listed above. A larger capacity power supply may
result in a larger initialization current.
This specification applies to Commercial and Industrial grade products only.
Ramp-up Time is measured from 0 V

. Peak current required lasts less than 3 ms, and occurs near the

XC4000XL A.C. Characteristics
Testing of the switching parameters is modeled after testing methods specified by MIL-M-38510/605. All devices are 100%
functionally tested. Internal timing parameters are derived from measuring internal test patterns. Listed below are
representative values where one global clock input drives one vertical clock line in each accessible column, and where all
accessible IOB and CLB flip-flops are clocked by the global clock net.
When fewer vertical clock lines are connected, the clock distribution is faster; when multiple clock lines per column are driven
from the same global clock, the delay is longer. For more specific, more precise, and worst-case guaranteed data, reflecting
the actual routing structure, use the values provided by the static timing analyzer (TRCE in the Xilinx Development System)
and back-annotated to the simulation netlist. These path delays, provided as a guideline, have been extracted from the static
timing analyzer report. All timing parameters assume worst-case operating conditions (supply voltage and junction
temperature. Values apply to all XC4000XL devices and are expressed in nanoseconds unless otherwise noted.
