ProASICPLUS® Flash Family FPGAs

The ProASICPLUS family of devices, Actels second- generation Flash FPGAs APA075 APA150 APA300 APA450 APA600 APA750 APA1000 , offers enhanced performance over Actels ProASIC family. It combines the advantages of ASICs with the benefits of programmable devices through nonvolatile Flash technology. This enables engineers to create high-density systems using existing ASIC or FPGA design flows and tools. In addition, the ProASICPLUS family offers a unique Clock conditioning circuit based on two on-board phase-locked loops (PLLs). The family offers up to one million system Gates supported with up to 198 kbits of two-port SRAM and up to 712 user I/Os, all providing 50 MHz PCI performance. Advantages to the designer extend beyond performance. Unlike SRAM-based FPGAs four levels of routing hierarchy simplify routing, while the use of Flash technology allows all functionality to be live at power- up. No external boot PROM is required to support device programming. While on-board security mechanisms prevent access to the program information, reprogramming CAN be performed in-system to support future design iterations and field upgrades. The devices architecture mitigates the complexity of ASIC migration at higher user volume. This makes ProASICPLUS a cost- effective solution for applications in the networking, Communications computing, and avionics markets. The ProASICPLUS family achieves its nonvolatility and reprogrammability through an advanced Flash-based 0.22 m LVCMOS process with four layers of metal. Standard CMOS design techniques are used to implement Logic and control functions, including the PLLs and LVPECL inputs. This results in predictable performance compatible with Gate arrays.
