QL4009 QuickRAM Data Sheet Rev B
Architecture Overview
The QuickRAMTM family of ESPs (Embedded Standard Products) offers FPGA logic in
combination with Dual-Port SRAM modules. The QL4009 is a 9,000 usable PLD gate
member of the QuickRAM family of ESPs. QuickRAM ESPs are fabricated on a 0.35
µm
four-layer metal process using QuickLogic's patented ViaLinkTM technology to provide a
unique combination of high performance, high density, low cost, and extreme ease-of-use.
The QL4009 contains 160 logic cells and 8 Dual Port RAM modules (see Figure 1). Each
RAM module has 1,152 RAM bits, for a total of 9,216 bits. RAM Modules are Dual Port
(one read port, one write port) and can be configured into one of four modes: 64 (deep) x18
(wide), 128x9, 256x4, or 512x2 (see Figure 4). With a maximum of 82 I/Os, the QL4009
is available in 68-pin PLCC, 84-pin PLCC and 100-pin TQFP packages.
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 2). This approach allows up to 512-deep configurations as
large as 16 bits wide in the smallest QuickRAM device and 44 bits wide in the largest device.
Software support for the complete QuickRAM family, including the QL4009, is available
through two basic packages. The turnkey QuickWorksTM package provides the most
complete ESP software solution from design entry to logic synthesis, to place and route, to
simulation. The QuickToolsTM packages provides a solution for designers who use Cadence,
Exemplar, Mentor, Synopsys, Synplicity, Viewlogic, Aldec, or other third-party tools for
design entry, synthesis, or simulation.
The QuickLogic variable grain logic cell features up to 16 simultaneous inputs and 5 outputs
within a cell that can be fragmented into 5 independent cells. Each cell has a fan-in of 29
including register and control lines (see Figure 3).
