EP1C12Q240C8 Introduction

The Cyclone® field programmable gate array family is based on a 1.5-V,
0.13-μm, all-layer copper SRAM process, with densities up to
20,060 logic elements (LEs) and up to 288 Kbits of RAM. With features like
phase-locked 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. Cyclone devices support various I/O standards,
including LVDS at data rates up to 640 megabits per second (Mbps), and
66- and 33-MHz, 64- and 32-bit peripheral component interconnect (PCI),
for interfacing with and supporting ASSP and ASIC devices. Altera also
offers new low-cost serial configuration devices to configure Cyclone
devices.
