描述 Description

The AT40K/AT40KLV is a family of fully PCI-compliant, SRAM-based FPGAs with distributed 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.
