Description The AT40K/AT40KLV is a family of fully PCI-compliant, SRAM-based FPGAs with dis- tributed 10 ns programmable synchronous/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 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 5V designs for AT40K and 3.3V designs for AT40KLV. The AT40K/AT40KLV 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. Atmels design tools provide seamless integration with industry standard tools such as Synplicity, ModelSim, Exemplar and Viewlogic. The AT40K/AT40KLV can be used as a coprocessor for high-speed (DSP/processor- based) designs by implementing a variety of computation intensive, arithmetic functions. These 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 multime- dia applications. Fast, Flexible and The AT40K/AT40KLV FPGA offers a patented distributed 10 ns SRAM capability where the RAM can be used without losing logic resources. Multiple independent, synchronous Efficient SRAM or asynchronous, dual-port or single-port RAM functions (FIFO, scratch pad, etc.) can be created using Atmels macro generator tool. Fast, Efficient Array and The AT40K/AT40KLVs patented 8-sided core cell with direct horizontal, vertical and diagonal cell-to-cell connections implements ultra fast array multipliers without using Vector Multipliers any busing resources. The AT40K/AT40KLVs Cache Logic capability enables a large number of design coefficients and variables to be implemented in a very small amount of silicon, enabling vast improvement in system speed at much lower cost than conven- tional FPGAs. 2 AT40K/AT40KLV Series FPGA 0896CSFPGA05/02
