The Cyclone® field programmable gate array family is based on a 1.5-V, 0.13-μm, all-layer copper SRAMprocess, with densities up to 20,060 logic elements (LEs) and up to 288 Kbits of RAM. With features like phaselocked loops (PLLs) for clocking and a dedicated double data rate (DDR) interface to meet DDR SDRAM and fast cycle RAM (FCRAM) memory requirements, Cyclone devices are a cost-effective solution for data-path applications.
●Features The Cyclone device family offers the following features:
●■ 2,910 to 20,060 LEs, see Table 1–1
●■ Up to 294,912 RAM bits (36,864 bytes)
●■ Supports configuration through low-cost serial configuration device
●■ Support for LVTTL, LVCMOS, SSTL-2, and SSTL-3 I/O standards
●■ Support for 66- and 33-MHz, 64- and 32-bit PCI standard
●■ High-speed (640 Mbps) LVDS I/O support
●■ Low-speed (311 Mbps) LVDS I/O support
●■ 311-Mbps RSDS I/O support
●■ Up to two PLLs per device provide clock multiplication and phase shifting
●■ Up to eight global clock lines with six clock resources available per logic array block (LAB) row
●■ Support for external memory, including DDR SDRAM (133 MHz), FCRAM, and single data rate (SDR) SDRAM
●■ Support for multiple intellectual property (IP) cores, including Altera®MegaCore® functions and Altera Megafunctions Partners Program (AMPPSM ) megafunctions.
