About Stratix Series High-End FPGAs
The Stratix® series of FPGA families enables you to deliver high-performance, state-of-the-art products to market faster with lower risk and higher productivity. By combining high density, high performance, and a rich feature set, FPGAs in the Stratix series allow you to integrate more functions and maximize system bandwidth. The Stratix series of FPGA families includes GX variant devices with on-chip transceivers—serializer/deserializer (SERDES)—to allow the transfer of data in and out of the FPGA at high frequencies.

All of the Stratix FPGA series families have HardCopy® ASIC equivalent devices. HardCopy ASICs provide a path to low-cost volume production with low risk through FPGA prototyping of your design. Stratix series FPGAs are also ideal for the prototyping and verification of Standard Cell ASICs.
Stratix IV FPGAs are the fourth-generation Stratix FPGA family and provide the highest density, highest performance and lowest power of any 40-nm FPGA. With enhanced (E) and enhanced with transceivers (GX) variants, Stratix IV FPGAs address many markets and applications, such as wireless and wireline communications, military, and broadcast.
Stratix III FPGAs are the industry’s lowest power high-performance 65-nm FPGAs. Logic rich (L) and enhanced for memory (E) and digital signal processing (DSP) variants allow you to balance your resource requirements to your design without having to design in a device any bigger than is absolutely necessary—saving board real estate, compilation time, and money. Stratix III FPGAs target high-end core system processing designs in many applications.
Stratix II and Stratix II GX variant FPGAs introduced the adaptive logic module (ALM) architecture, which uses a high-performance, 8-input fracturable look-up table (LUT) in place of a 4 input LUT, and which is found in Altera's newest high-end FPGAs today. This second-generation high-performance FPGA family includes best-in-class 6.375-Gbps transceiver-based variant devices. These Stratix II GX FPGAs are available in volume and are still highly recommended for new designs.
Stratix and the Stratix GX variants are the original members of the Stratix FPGA series. This high-performance FPGA family introduced DSP hard IP blocks along with Altera's ubiquitous TriMatrix on-chip memory and flexible I/O structures.
