Description

 The AT40KAL is a family of fully PCI-compliant, SRAM-based FPGAs with distributed 10 ns programmable synchron-ous/asynchronous, dual-port/single-port SRAM, 8 global clocks, Cache Logic ability (partially or fully reconfigurable without loss of data), automatic component generators, and range of AT40K05AL in size from 5,000 to 50,000 usable gates. I/O counts range from 128 to 384 in industry standard packages ranging from 84-pin PLCC to 352-ball Square BGA, and support 3.3V designs.

The AT40KAL is designed to quickly implement high-performance, large gate count designs through the use of synthesis and schematic-based tools used on a PC or Sun platform. Atmel's design tools provide seamless integration with industry standard tools such as Synplicity, ModelSim, Exemplar and Viewlogic. See the "IDS Datasheet" available on the Atmel web site (http://www.atmel.com/atmel/acrobat/doc1421.pdf) for a list of other supported tools.

The AT40KAL can be used as a coprocessor for high-speed (DSP/processor-based) designs by implementing a variety of computation intensive, arithmetic functions. AT40K05AL include adaptive finite impulse response (FIR) filters, fast Fourier transforms (FFT), convolvers, interpolators and discrete-cosine transforms (DCT) that are required for video compression and decompression, encryption, convolution and other multimedia applications.
