Arria 10 Devices
This section covers the remote system configuration modes, components, parameter, ports, and
parameter settings for Arria ® 10 devices.
Remote System Configuration Mode
Arria 10 devices support remote configuration mode only.
Remote configuration supports “Direct to application” and “Application to Application” update. Remote
configuration only supports 4-bytes address scheme so there is no support for devices with densities
smaller than 128Mbit.

When used with low-voltage quad-serial configuration (EPCQ-L) devices, the remote update mode allows
a configuration space to start at any flash sector boundary, allowing a maximum of 512 pages in the
EPCQ-L256 device and 1024 pages in the EPCQ-L512 device, in which the minimum size of each page is
512Kbits. Additionally, the remote update mode features a user watchdog timer that can detect functional
errors in an application configuration.
