Introduction
Following the immensely successful first-generation Cyclone
®
device
family, Altera
®
Cyclone II 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 Cyclone II 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 Cyclone II 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:

Nios II Embedded Processor support
The Cyclone II family offers devices with the Fast-On feature, which
offers a faster power-on-reset (POR) time. 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.
For more information on POR time specifications for Cyclone II A and
non-A devices, refer to the
Hot Socketing & Power-On Reset
chapter in the
Cyclone II Device Handbook.
