Introduction
Preliminary
Information
The Cyclone
TM
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 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.

Preliminary Information
Functional
Description
Cyclone devices contain a two-dimensional row- and column-based
architecture to implement custom logic. Column and row interconnects of
varying speeds provide signal interconnects between LABs and
embedded memory blocks.
The logic array consists of LABs, with 10 LEs in each LAB. An LE is a small
unit of logic providing efficient implementation of user logic functions.
LABs are grouped into rows and columns across the device. Cyclone
devices range between 2,910 to 20,060 LEs.
M4K RAM blocks are true dual-port memory blocks with 4K bits of
memory plus parity (4,608 bits). These blocks provide dedicated true
dual-port, simple dual-port, or single-port memory up to 36-bits wide at
up to 200 MHz. These blocks are grouped into columns across the device
in between certain LABs. Cyclone devices offer between 60 to 288 Kbits of
embedded RAM.
Each Cyclone device I/O pin is fed by an I/O element (IOE) located at the
ends of LAB rows and columns around the periphery of the device. I/O
pins support various single-ended and differential I/O standards, such as
the 66-MHz, 32-bit PCI standard and the LVDS I/O standard at up to
311 Mbps. Each IOE contains a bidirectional I/O buffer and three registers
for registering input, output, and output-enable signals. Dual-purpose
DQS, DQ, and DM pins along with delay chains (used to phase-align DDR
signals) provide interface support with external memory devices such as
DDR SDRAM, and FCRAM devices at up to 133 MHz (266 Mbps).
Cyclone devices provide a global clock network and up to two PLLs. The
global clock network consists of eight global clock lines that drive
throughout the entire device. The global clock network can provide clocks
for all resources within the device, such as IOEs, LEs, and memory blocks.
The global clock lines can also be used for control signals. Cyclone PLLs
provide general-purpose clocking with clock multiplication and phase
shifting as well as external outputs for high-speed differential I/O
support.
