QL3025 pASIC 3 FPGA Data Sheet Rev E
Architecture Overview
The QL3025 is a 25,000 usable PLD gate member of the pASIC 3 family of FPGAs.
pASIC 3 FPGAs are fabricated on a 0.35
µm
four-layer metal process using QuickLogic
's
patented ViaLink
technology to provide a unique combination of high performance, high
density, low cost, and extreme ease-of-use.
The QL3025 contains 672 logic cells. With a maximum of 204 I/Os, the QL3025 is
available in
144-pin TQFP, 208-pin PQFP, and 256-pin PBGA packages.
Software support for the complete pASIC 3 family, including the QL3025, is available
through three basic packages. The turnkey QuickWorks
package provides the most
complete FPGA software solution from design entry to logic synthesis, to place and route,
to simulation. The QuickTools
TM
for Workstations package provides a solution for designers
who use Cadence
, Exemplar
TM
, Mentor
, Synopsys
, Synplicity
, Viewlogic
TM
, Aldec
TM
,
or other third-party tools for design entry, synthesis, or simulation.

C. Multiply by the appropriate Delay Factor, K, for speed grade, voltage, and temperature
settings as specified in

b. These limits are derived from a representative selection of the slowest paths through the
pASIC 3 logic cell including typical net delays. Worst case delay values for specific paths should
be determined from timing analysis of your particular design.

a. The array distributed networks consist of 40 half columns and the global distributed networks con-
sist of 44 half columns, each driven by an independent buffer. The number of half columns used
does not affect clock buffer delay. The array clock has up to eight loads per half column. The glo-
bal clock has up to 11 loads per half column.
