What is the Cyclone II FPGA family?

The Cyclone II FPGA family is the second-generation family in our low-cost Cyclone series. Cyclone II FPGAs offer 30 percent lower cost and more than three times the logic density than first-generation Cyclone devices. Based on TSMC's proven 90-nm process technology with low-k dielectric, Cyclone II FPGAs are the lowest-cost FPGAs in the industry.

With densities ranging from 4,608 to 68,416 logic elements (LEs), Cyclone II FPGAs also offer new and enhanced features including up to 1.1 Mbits of embedded memory, up to 150 embedded 18 x 18 multipliers, phase-locked loops (PLLs), and support for external memory interfaces and differential and single-ended I/O standards.

What is the process technology for the Cyclone II FPGA family?

The Cyclone II FPGA family is based on the 1.2-V, 90-nm, low-k dielectric process from TSMC, the same process technology used for Stratix II FPGAs.

Which markets does the Cyclone II FPGA family address?

The Cyclone II FPGA family is the optimum low-cost solution for high-volume applications in a wide variety of markets, including: consumer electronics, advanced communications and wireless, computer peripherals, industrial, and automotive. Selected Cyclone II FPGAs are available with industrial temperature or automotive- grade versions. Cyclone II FPGAs contain a number of new and enhanced features such as embedded memory, embedded multipliers, PLLs, and low-cost package offerings optimized for volume applications such as video displays, digital TVs (DTVs), digital set-top boxes (DSTBs), DVD players, DSL modems, residential gateways, and mid-range and low-end routers.

Why are Cyclone II FPGAs an ideal alternative to standard-cell ASICs?

The Cyclone II family provides a flexible, risk-free option without up-front non-recurring engineering (NRE) charges or minimum order quantities. In addition to a cost structure unmatched by any other FPGA, Cyclone II FPGAs offer advanced features such as embedded 18 x 18 multipliers for high-performance digital signal processing (DSP) applications, and support for memory interfaces such as DDR2 (up to 334 Mbps) and QDRII (up to 688 Mbps).

What are the members of the Cyclone II FPGA family, and what packages will be offered?

The Cyclone II FPGA family includes six members ranging in density from 4,608 to 68,416 LEs. Low-cost packages with vertical migration support are available for Cyclone II FPGAs, including the thin quad flat pack (TQFP), plastic quad flat pack (PQFP), and FineLine BGA packages. Table 1 provides an overview of the Cyclone II family, and Table 2 lists the package options and user I/O pins.

The following tables contain downloadable files listing Intel FPGA device pin-out descriptions. There are up to three types of files for each device: Portable Document Format Files (.pdf), Text Files (.txt), and Microsoft Excel Files (.xls).

You can view PDF files in Adobe Acrobat. The text files are tab delimited, and are most easily viewed using a spreadsheet program, such as Microsoft Excel. Use the following steps to open the text files in Microsoft Excel on a Windows operating system.

  1. Open the Microsoft Excel program.
  2. Choose Open (File menu).
  3. Locate the text file and choose the Open button.
  4. In the first page of the Text Import Wizard, choose the Delimited radio button in the Original data type box. Click the Next button.
  5. In the second page of the Text Import Wizard, check Tab in the Delimiters box. Click the Next button.
  6. In the third page of the Text Import Wizard, choose the Generalradio button in the Column data format box. Click the Finish button.

You can open both the PDF and text files on Unix, Windows, and Macintosh operating systems.

Pin-out tables are available for the following device families:
