ARCHITECTURE OVERVIEW
Architecture Overview
The QuickRAM family of ESPs (Embedded Standard
Products) offers FPGA logic in combination with DualPort SRAM modules. The QL4036 is a 36,000
usable PLD gate member of the QuickRAM family of
ESPs. QuickRAM ESPs are fabricated on a 0.35mm
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 QL4036 contains 672 logic cells and 14 dual
port RAM modules (see Figure 1). Each RAM module
has 1,152 RAM bits, for a total of 16,128 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 2). With a maximum of 204 I/Os, the QL4036 is
available in 144-pin TQFP, 208-pin PQFP and 256pin PBGA 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
3). 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.

PRODUCT SUMMARY
Product Summary
Product Summary
Total of 204 I/O Pins
■
196 bi-directional input/output pins, PCI-compliant for
5.0 volt and 3.3 volt buses for -1/-2/-3/-4 speed grades
■
8 high-drive input/distributed network pins
Eight Low-Skew Distributed Networks
■
Two array clock/controlnetworks available to the logic
cell flip-flop clock, set and reset inputs - each driven by
and input-only pin
■
Six global clock/control networks available to the logic
cell F1, clock, set and reset inputs and the input and I/O
register clock, reset and enable inputs as well as the output enable control - each driven by an input-only or I/O
pin, or any logic cell output or I/O cell feedback
FIGURE 2. QuickRAM Module
Software support for the complete QuickRAM family, including the QL4016, 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, Syn-opsys, Synplicity, Viewlogic,
Veribest, or other third-party tools for design entry,
synthesis, or simulation.
High Performance
■
Input + logic cell + output total delays under 6 ns
■
Data path speeds over 400 MHz
■
Counter speeds over 300 MHz
■
FIFO speeds over 160+ MHz
The QuickLogic variable grain logic cell features up
to 16 simultaneous inputs and 5 outs 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 4).

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
customer engineering.

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 QuickRAM 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.
