Logic Cell Array Family
Product Specification
Features
Description
XC3000 is the original family of devices in the XC3000
class of Field Programmable Gate Array (FPGA) architec-
tures. The XC3000 family has a proven track record in
addressing a wide range of design applications, including
general logic replacement and sub-systems integration.
For a thorough description of the XC3000 architecture see
the preceding pages of this data book.
The XC3000 Family covers a range of nominal device
densities from 2,000 to 9,000 gates, practically achievable
densities from 1,000 to 6,000 gates. Device speeds,
described in terms of maximum guaranteed toggle fre-
quencies, range from 70 to 125 MHz. The performance of
a completed design depends upon placement and routing
implementation, so, like with any gate array, the final
verification of device utilization and performance can only
be known after the design has been placed and routed.

– 4-mA output sink and source current
– Broad range of package options includes plastic and
ceramic quad flat packs, plastic leaded chip carriers
and pin grid arrays
– 100% bitstream compatible with the XC3100 family
– Commercial, industrial, military, “high rel”, and MIL-
STD-883 Class B grade devices
– Easy migration to XC3300 series of HardWire mask-
programmed devices for high-volume production

CLB Switching Characteristic Guidelines (continued)
Testing of the switching parameters is modeled after testing methods specified by MIL-M-38510/605. All devices are 100%
functionally tested. Since many internal timing parameters cannot be measured directly, they are derived from benchmark timing
patterns. The following guidelines reflect worst-case values over the recommended operating conditions. For more detailed, more
precise, and more up-to-date timing information, use the values provided by the XACT timing calculator and used in the simulator.
