PRODUCT SUMMARY
Product Summary
The QL3060 is a 60,000 usable PLD gate member of
the pASIC 3 family of FPGAs. pASIC 3 FPGAs are
fabricated on a 0.35mm 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 QL3060 contains 1,584 logic cells. With a
maximum of 316 I/Os, the QL3060 is available in
208-PQFP and 456-pin PBGA packages.
Software support for the complete pASIC 3 family,
including the QL3060, 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 QuickToolsTM for
Workstations package provides a solution for
designers who use Cadence, Exemplar, Mentor,
Synopsys, Synplicity, Viewlogic, Veribest, or other
third-party tools for design entry, synthesis, or
simulation.

Notes:
[1] Applies only to -1/-2/-3/-4 commercial grade devices. These speed grades are also PCI-compliant. All
other devices have 8 mA IOL specifications.
[2] Capacitance is sample tested only. Clock pins are 12 pF maximum.
[3] Only one output at a time. Duration should not exceed 30 seconds.
[4] For -1/-2/-3/-4 commercial grade devices only. Maximum ICC is 3 mA for -0 commercial grade and all
industrial grade devices, and 5 mA for all military grade devices. For AC conditions, contact QuickLogic

Notes:
[5] Stated timing for worst case Propagation Delay over process variation at VCC=3.3V and TA=25°C. Multiply
by the appropriate Delay Factor, K, for speed grade, voltage and temperature settings as specified in the
Operating Range.
[6] 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.

Notes:
[7] The array distributed networks consist of 40 half columns and the global distributed networks consist 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 8 loads per half column. The global clock has up to 11 loads per half
column.
