1. Introduction CII51001-3.2 Introduction Following the immensely successful first-generation Cyclone® device family, Altera® CycloneII FPGAs extend the low-cost FPGA density range to 68,416 logic elements (LEs) and provide up to 622 usable I/O pins and up to 1.1 Mbits of embedded memory. Cyclone II FPGAs are manufactured on 300-mm wafers using TSMC's 90-nm low-k dielectric process to ensure rapid availability and low cost. By minimizing silicon area, Cyclone II devices can support complex digital systems on a single chip at a cost that rivals that of ASICs. Unlike other FPGA vendors who compromise power consumption and performance for low-cost, Altera’s latest generation of low-cost FPGAs—Cyclone II FPGAs, offer 60% higher performance and half the power consumption of competing 90-nm FPGAs. The low cost and optimized feature set of CycloneII FPGAs make them ideal solutions for a wide array of automotive, consumer, communications, video processing, test and measurement, and other end-market solutions. Reference designs, system diagrams, and IP, found at www.altera.com, are available to help you rapidly develop complete end-market solutions using CycloneII FPGAs. Low-Cost Embedded Processing Solutions Cyclone II devices support the Nios II embedded processor which allows you to implement custom-fit embedded processing solutions. Cyclone II devices can also expand the peripheral set, memory, I/O, or performance of embedded processors. Single or multiple Nios II embedded processors can be designed into a Cyclone II device to provide additional co-processing power or even replace existing embedded processors in your system. Using Cyclone II and Nios II together allow for low-cost, high-performance embedded processing solutions, which allow you to extend your product's life cycle and improve time to market over standard product solutions. Low-Cost DSP Solutions Use Cyclone II FPGAs alone or as DSP co-processors to improve price-to-performance ratios for digital signal processing (DSP) applications. You can implement high-performance yet low-cost DSP systems with the following Cyclone II features and design support: ■ Up to 150 18 × 18 multipliers ■ Up to 1.1 Mbit of on-chip embedded memory ■ High-speed interfaces to external memory Altera Corporation 1–1 February 2008

Features ■ DSP intellectual property (IP) cores ■ DSP Builder interface to The Mathworks Simulink and Matlab design environment ■ DSP Development Kit, Cyclone II Edition Cyclone II devices include a powerful FPGA feature set optimized for low-cost applications including a wide range of density, memory, embedded multiplier, and packaging options. Cyclone II devices support a wide range of common external memory interfaces and I/O protocols required in low-cost applications. Parameterizable IP cores from Altera and partners make using Cyclone II interfaces and protocols fast and easy.

Devices that support the Fast-On feature are designated with an “A” in the device ordering code. For example, EP2C5A, EP2C8A, EP2C15A, and EP2C20A. The EP2C5A is only available in the automotive speed grade. The EP2C8A and EP2C20A are only available in the industrial speed grade. The EP2C15A is only available with the Fast-On feature and is available in both commercial and industrial grades. The Cyclone II “A” devices are identical in feature set and functionality to the non-A devices except for support of the faster POR time. f Cyclone II A devices are offered in automotive speed grade. For more information, refer to the Cyclone II section in the Automotive-Grade Device Handbook. f For more information on POR time specifications for CycloneII A and non-A devices, refer to the Hot Socketing & Power-On Reset chapter in the CycloneII Device Handbook.

(2) The Quartus® II software I/O pin counts include four additional pins, TDI, TDO, TMS, and TCK, which are not available as general purpose I/O pins. (3) TQFP: thin quad flat pack. (4) PQFP: plastic quad flat pack. (5) Vertical migration is supported between the EP2C5F256 and the EP2C8F256 devices. However, not all of the DQ and DQS groups are supported. Vertical migration between the EP2C5 and the EP2C15 in the F256 package is not supported. (6) The I/O pin counts for the EP2C5, EP2C8, and EP2C15A devices include 8 dedicated clock pins that can be used for data inputs. The I/O counts for the EP2C20, EP2C35, EP2C50, and EP2C70 devices include 16 dedicated clock pins that can be used for data inputs. (7) EP2C8A, EP2C15A, and EP2C20A have a Fast On feature that has a faster POR time. The EP2C15A is only available with the Fast On option. (8) The EP2C5 optionally support the Fast On feature, which is designated with an “A” in the device ordering code. The EP2C5A is only available in the automotive speed grade. Refer to the Cyclone II section in the Automotive-Grade Device Handbook. CycloneII devices support vertical migration within the same package (for example, you can migrate between the EP2C35, EPC50, and EP2C70 devices in the 672-pin FineLine BGA package). The exception to vertical migration support within the CycloneII family is noted in Table1–3. 1–6 Altera Corporation Cyclone II Device Handbook, Volume 1 February 2008

Introduction Vertical migration means that you can migrate to devices whose dedicated pins, configuration pins, and power pins are the same for a given package across device densities.

(2) When migrating from the EP2C20F484 device to the EP2C50F484 device, a total of 39 I/O pins are non-migratable. (3) When migrating from the EP2C35F672 device to the EP2C70F672 device, a total of 56 I/O pins are non-migratable. (4) In addition to the one non-migratable I/O pin, there are 34 DQ pins that are non-migratable. (5) The pinouts of 484 FBGA and 484 UBGA are the same. 1 When moving from one density to a larger density, I/O pins are often lost because of the greater number of power and ground pins required to support the additional logic within the larger device. For I/O pin migration across densities, you must cross reference the available I/O pins using the device pin-outs for all planned densities of a given package type to identify which I/O pins are migratable. To ensure that your board layout supports migratable densities within one package offering, enable the applicable vertical migration path within the QuartusII software (go to Assignments menu, then Device, then click the Migration Devices button). After compilation, check the information messages for a full list of I/O, DQ, LVDS, and other pins that are not available because of the selected migration path. Table1–3 lists the CycloneII device package offerings and shows the total number of non-migratable I/O pins when migrating from one density device to a larger density device.
