描述 Description

AT6000 Series SRAM-based Field Programmable Gate Arrays (FPGAs) are ideal for use as reconfigurable coprocessors and implementing compute-intensive logic.
Supporting system speeds greater than 100 MHz and using a typical operating current of 15 to 170 mA, AT6000 Series devices are ideal for high-speed, compute-intensive designs. These FPGAs are designed to implement Cache Logic?, which provides the user with the ability to implement adaptive hardware and perform hardware acceleration.
The patented AT6000 Series architecture employs a symmetrical grid of small yet powerful cells connected to a flexible busing network. Independently controlled clocks and resets govern every column of cells. The array is surrounded by programmable I/O.
Devices range in size from 4,000 to 30,000 usable gates, and 1024 to 6400 registers. Pin locations are consistent throughout the AT6000 Series for easy design migration. High-I/O versions are available for the lower gate count devices.
