INTRODUCTION
The RadHard Eclipse Field Programmable Gate Array Family
(FPGA) offers up to 320,000 system gates including Dual-Port
RadHard SRAM modules. It is fabricated on 0.25μm five-layer
metal ViaLink CMOS process and contains a maximum of 1,536
logic cells and 24 dual-port RadHard SRAM modules (see
Figure 1 Block Diagram). Each RAM module has 2,304 RAM
bits, for a maximum total of 55,300 bits. Please reference
product family comparison chart on page 2.
RAM modules are Dual Port (one asynchronous/synchronous
read port, one write port) and can be configured into one of four
modes (see Figure 2). Designers can cascade multiple RAM
modules to increase the depth or width allowed in single
modules by connecting corresponding address lines together and
dividing the words between modules (see Figure 3). This
approach allows a variety of address depths and word widths to
be tailored to a specific application.
The RadHard Eclipse FPGA is available in a 208-pin Cerquad
Flatpack, allowing access to 99 bidirectional signal I/O, 1
dedicated clock, 8 programmable clocks and 16 high drive
inputs. Other package options include a 288 CQFP, 484 CCGA
and a 484 CLGA.
Aeroflex uses QuickLogic Corporation’s licensed ESP
(Embedded Standard Products) technology. QuickLogic is a
pioneer in the FPGA semiconductor and software tools field.

• Up to 310 bi-directional input/output pins, PCI-compliant for
3.3V buses (see Table 4)
• Each bidirectional I/O contains RadHard flip-flops for input,
output, and output enable lines
Distributed Networks
• One, dedicated clock network, hardwired to each logic cell
flip-flop clock pin to minimize skew
• Three programmable, global clock networks accessible from
clock input only pins

Software support for the product is available from QuickLogic.
The turnkey QuickWorks
TM
package provides the most com-
plete software solution from design entry to logic synthesis,
place and route, simulation, static timing, and power analysis.
The QuickTools
TM
for Workstations package provides a solu-
tion for designers who use Cadence, Exemplar, Mentor, Synop-
sys, Synplicity, Viewlogic, Veribest or other third-party tools
for design entry, synthesis, simulation. Please visit Quick Log-
ic’s website at www.quicklogic.com for more information.
The variable grain logic cell features up to 17 simultaneous in-
puts and 6 outputs within a cell that can be fragmented into 6
independent sections. Each cell has a fan-in of 30 including
register and control lines (see Figure 5).
• Eight programmable clock networks, accessible from clock
pins or internal logic
• 20 pre-defined Quad-clock networds, five per quadrant. Ac-
cessed by the 8 programmable global clock networks
• Sixteen high drive inputs. Two inputs located in each of the
eight I/O banks. Used as clock or enable signals for the I/O
RadHard flip-flops, or as high drive inputs for internal logic
Typical Performance
• Input + logic cell + output total delays under 12ns
• Data path speeds over 120 MHz
• Counter speeds over 120 MHz
