AS Configuration (Serial Configuration Devices)
Cyclone IV Device Handbook, Volume 1
f
1
For Cyclone IV E devices, the Quartus II software prohibits you from using the LVDS
I/O standard in I/O Bank 1 when the configuration device I/O voltage is not 2.5 V. If
you need to assign LVDS I/O standard in I/O Bank 1, navigate to
Assignments>Device>Settings>Device and Pin Option>Configuration to change
the Configuration Device I/O voltage to 2.5 V or Auto.
In the AS configuration scheme, Cyclone IV devices are configured with a serial
configuration device. These configuration devices are low-cost devices with
non-volatile memories that feature a simple four-pin interface and a small form factor.
These features make serial configuration devices the ideal low-cost configuration
solution.
For more information about serial configuration devices, refer to the
Configuration Devices (EPCS1, EPCS4, EPCS16, EPCS64, and EPCS128) Datasheet
volume 2 of the Configuration Handbook.
Serial configuration devices provide a serial interface to access the configuration data.
During device configuration, Cyclone IV devices read the configuration data through
the serial interface, decompress the data if necessary, and configure their SRAM cells.
This scheme is referred to as the AS configuration scheme because the device controls
the configuration interface.
Single-Device AS Configuration
The four-pin interface of serial configuration devices consists of the following pins:
