INTRODUCTION
The RadHard Eclipse Field Programmable Gate Array Family
(FPGA) offers up to 320,000 usable 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). 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.
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.
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
• Eight programmable clock networks, accessible from clock
pins or internal logic

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).
• 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
Performance
• Input + logic cell + output total delays under 12ns
• Data path speeds over 200 MHz
• Counter speeds over 150 MHz
• FIFO speeds over 60+ MHz
