Chapter 9: Configuration, Design Security, and Remote System Upgrades in Arria II Devices
Configuration Features
Configuration Devices
Altera^® serial configuration devices support single- and multi-device configuration
solutions for Arria II devices. Arria II GX devices use the active serial (AS)
configuration scheme while Arria II GZ devices use the fast AS configuration scheme.
Serial configuration devices offer a low-cost, low pin-count configuration solution.
f For more information about serial configuration devices, refer to the Serial
Configuration Devices (EPCS1, EPCS4, EPCS16, EPCS64, and EPCS128) Datasheet in
volume 2 of the Configuration Handbook.
1 All minimum timing information stated in this chapter covers the entire Arria II
device family. Some devices may work at less than the minimum timing stated in this
chapter due to process variations.
Configuration Features
Arria II devices offer decompression, design security, and remote system upgrade
features. Arria II devices can receive a compressed configuration bitstream and
decompress this data in real-time, reducing storage requirements and configuration
time. Design security using configuration bitstream encryption protects your designs.
You can make real-time system upgrades from remote locations of your Arria II
designs with the remote system upgrade feature.
Table 9–1 lists the configuration features you can use in each configuration scheme for
Arria II GX devices.

Notes to Table 9–1:
(1) In these modes, the host system must send a DCLK that is x4 the data rate.
(2) Remote system upgrade is only available in the AS configuration scheme. Local update mode is not supported in the AS configuration scheme.
