AT40Kxx Coprocessor Series FPGAs

Our AT40KAL coprocessor series FPGAs offer from 5K to 50K usable gates and are designed for high-density, compute-intensive Digital Signal Processing (DSP) and other fast logic designs. The AT40KAL family resolves the logic vs. SRAM tradeoff by providing fast, flexible and distributed 10 ns FreeRAM without using valuable logic resources. Structured logic functions, including variable array multipliers, can be implemented directly in core cells without using any busing resources, providing dramatic improvements in speed, utilization, power and system cost.

A key feature of the AT40KAL family of FPGAs is their Cache Logic capability, which enables you to reprogram part of the FPGA without losing register data, while the remainder of the FPGA continues to operate without disruption. This is an excellent choice for building adaptive filters, variable coefficient multipliers and other designs where the data path can be changed to increase system performance.

Offering massive register counts (1,024 to 6,400 registers), 5V AT40K FGPAs are designed to speed up processor-based system performance while reducing power consumption, part count and costs, making them well-suited for use as re-configurable DSP coprocessors.

We also offer a family of FPGA Serial Configuration EEPROMs in densities ranging from 256 kb to 4 Mb. This family of products can be programmed using a standard programmer or reprogrammed in-system like our FPGAs.
