key features.
Table 9–24. Security Key Features
AES volatile key zeroization is supported in Cyclone III LS devices. The volatile key
clear and key program JTAG instructions from the device core is supported to protect
Cyclone III LS devices against tampering. You can clear and reprogram the key from
the device core whenever tampering attempt is detected by executing the
KEY_CLR_VREG and KEY_PROG_VOL JTAG instructions to clear and reprogram the
volatile key, and then reset the Cyclone III LS device by pulling the nCONFIG pin low
for at least 500 ns. When nCONFIG returns to a logic-high level and nSTATUS is
released by the Cyclone III LS device, reconfiguration begins to configure the
Cyclone III LS device with a benign or unencrypted configuration file. After
configuration is successfully completed, observe the cyclecomplete signal from
error detection block to ensure that reconfigured CRAM bits content is correct for at
least one error detection cycle. You can also observe the cyclecomplete and
crcerror signals for any unintentional CRAM bits change.
cyclecomplete is a signal that is routed from the error detection block to the core
for the purpose of every complete error detection cycle. You must include the
cycloneiiils_crcblock WYSIWYG atom in your design to use the
cyclecomplete signal. For more information about the SEU mitigation, refer to the

power to the volatile register regardless of the on-chip supply condition. The nominal
voltage for this supply is 3.0 V, while its valid operating range is from 1.2 to 3.3 V. If
you do not use the volatile security key, you may connect the V
3.0-V power supply.
After power-up, wait for 200 ms (Standard POR) or 9 ms (Fast POR) before beginning
the key programming to ensure that V
As an example, BR1220 (-30°C to +80°C) and BR2477A (-40 C to +125°C) are lithium
coin-cell type batteries used for volatile key storage purposes.
