Architecture Overview
The QuickRAM
Port SRAM modules. The QuickRAM family of ESPs have up to 90,000 usable PLD gates. QuickRAM ESPs
are fabricated on a 0.35 µm four-layer metal process using QuickLogic's patented ViaLink
provide a unique combination of high performance, high density, low cost, and extreme ease-of-use.
The QuickRAM family contains a range of 160 to 1,584 logic cells and 8 to 22 dual port RAM Modules
(see
Table
modes: 64 (deep) x18 (wide), 128x9, 256x4, or 512x2 (see
QuickRAM family of ESPs are available in many device/package combinations (see
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
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.
