Atmel's AT40K Series coprocessor FPGAs range from 5K to 150K usable gates, and are designed for high density, compute-intensive DSP and other fast logic designs. The AT40K solves the Logic vs. SRAM trade-off problem by providing fast, flexible, distributed 10ns FreeRAM^TM without using valuable logic resources. Structured logic functions, including variable array multipliers can be implemented directly in core cells without using any bussing resources - providing dramatic improvements in speed, utilization, power and system cost.

Atmel FPGA technology is now available as an embedded core. The first family of products based on this technology is the FPSLIC family. FPSLIC (Field Programmable System Level Integrated Circuits) devices combine 10 - 40K of AT40F FPGA with 36K of SRAM and a 30+ Mips AVR MCU.

Atmel's AT00 Series FPGAs are designed to speed up processor-based system performance while lowering power, part count and cost. The massive register counts (1,024 - 6,400 registers) make them ideal for use as re-configurable DSP co-processors. They can increase system speeds by more than tenfold by off-loading "bottleneck" DSP software functions into hardware.

Both the AT00 and AT40K Series are the only FPGAs with the ability to implement Cache Logic design, where part of the FPGA can be reprogrammed without loss of register data, while remainder of the FPGA continues to operate without disruption. This is ideal for building adaptive filters, variable coefficient multipliers and other designs where the datapath can change to increase system performance.

All Atmel FPGAs can be designed using industry standard CAE tools for schematics, VHDL and Verilog on a PC, Sun and HP workstations, please note tools are available here: http://www.atmel.com/fpga_software.html.

Atmel has a family of FPGA Serial Configuration EEPROMs in densities ranging from 64K to 2 Mb. This unique family of products offers in-system reprogrammability as well as the ability to program using a standard programmer. Now, not only is the FPGA reprogrammable in-system; so is the configuration memory.
