Available Security Modes
Cyclone III Device Handbook, Volume 1
There are several security modes available on Cyclone III LS devices, they are:
■
■
■
Volatile Key
Secure operation with volatile key programmed and required external battery—this
mode accepts both encrypted and unencrypted configuration bitstreams. Use the
unencrypted configuration bitstream support for board-level testing only.
No Key Operation
Only unencrypted configuration bitstreams are allowed to configure the device.
FACTORY Mode
After power up, Cyclone III LS devices must be in FACTORY mode to program the
volatile key. The FACTORY private JTAG instruction must be issued after the device
successfully exits from POR and before the device starts loading the core
configuration data to enable access to all other instructions from the JTAG pins. The
device configuration data and AES volatile key are cleared if the FACTORY instruction
is executed.
