SUMMARY
The QL8x12B is a member of the pASIC 1 Family of very-high-speed
CMOS user-programmable ASIC devices. The 96 logic cell fieldprogrammable gate array (FPGA) offers 1,000 usable “gate array” gates
(equivalent to 2,000 usable PLD gates) of high-performance generalpurpose logic in 44-pin and 68-pin PLCC packages and 100-pin TQFP
packages.
Low-impedance, metal-to-metal, ViaLink interconnect technology
provides nonvolatile custom logic capable of operating above 150 MHz.
Logic cell delays under 2 ns, combined with input delays of under 1.5 ns
and output delays under 3 ns, permit high-density programmable devices
to be used with today’s fastest microprocessors and DSPs.
Designs can be entered using QuickLogic’s QuickWorks Toolkit or most
populart third-party CAE tools. QuickWorks combines Verilog/VHDL
design entry and simulation tools with device-specific place & route and
programming software. Ample on-chip routing channels allow fast, fully
automatic place and route of designs using up to 100% of the logic and
I/O cells, while maintaining fixed pin-outs.

Capacitance is sample tested only. CI = 20 pF max on I/(SI).
Only one output at a time. Duration should not exceed 30 seconds.
Commercial temperature grade only. Maximum Icc for industrial grade is 15mA and for military grade is
20 mA. For AC conditions use the formula described in the Section 9 — Power vs Operating Frequency.
Stated timing for worst case Propagation Delay over process variation at VCC = 5.0V and TA = 25°C.
Multiply by the appropriate Delay Factor, K, for speed grade, voltage and temperature settings as specified
in the Operating Range.
These limits are derived from a representative selection of the slowest paths through the pASIC logic cell
including net delays. Worst case delay values for specific paths should be determined from timing analysis
of your particular design .

Propagation delays depend on routing, fanout, load capacitance, supply voltage, junction temperature,
and process variation. The AC Characteristics are a design guide to provide initial timing estimates at
nominal conditions. Worst case estimates are obtained when nominal propagation delays are multiplied
by the appropriate Delay Factor, K, as specified in the Delay Factor table (Operating Range). The
effects of voltage and temperature variation are illustrated in the graphs on page 4-47, K Factor versus
Voltage and Temperature. The pASIC Development Tools incorporate data sheet AC Characteristics
into the QDIF database for pre-place-and-route timing analysis. The SpDE Delay Modeler extracts
specific timing parameters for precise path analysis or simulation results following place and route.
