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.
