A Comprehensive Guide to EP4CGX22BF14C8N Cyclone® IV GX Field Programmable Gate Array (FPGA) IC

Cyclone® IV GX Field Programmable Gate Array (FPGA) IC 72 774144 21280 169-LBGA

Introduction

The CycloneTM field programmable gate array family is based ona 1.5-V,

0.13-um, alayer 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 311 megabits per second (Mbps) and 66-MHz,

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.
