Chapter 1: Cyclone III Device Family Overview  
1–11  
Cyclone III Device Family Architecture  
Configuration  
Cyclone III device family uses SRAM cells to store configuration data. Configuration  
data is downloaded to Cyclone III device family each time the device powers up.  
Low-cost configuration options include the Altera EPCS family serial flash devices as  
well as commodity parallel flash configuration options. These options provide the  
flexibility for general-purpose applications and the ability to meet specific  
configuration and wake-up time requirements of the applications. Cyclone III device  
family supports the AS, PS, FPP, and JTAG configuration schemes. The AP  
configuration scheme is only supported in Cyclone III devices.

For more information about configuration, refer to the Configuration, Design Security,  
and Remote System Upgrades in the Cyclone III Device Family chapter.  
Remote System Upgrades  
Cyclone III device family offers remote system upgrade without an external  
controller. The remote system upgrade capability in Cyclone III device family allows  
system upgrades from a remote location. Soft logic (either the Nios II embedded  
processor or user logic) implemented in Cyclone III device family can download a  
new configuration image from a remote location, store it in configuration memory,  
and direct the dedicated remote system upgrade circuitry to start a reconfiguration  
cycle. The dedicated circuitry performs error detection during and after the  
configuration process, and can recover from an error condition by reverting to a safe  
configuration image. The dedicated circuitry also provides error status information.  
Cyclone III devices support remote system upgrade in the AS and AP configuration  
scheme. Cyclone III LS devices support remote system upgrade in the AS  
configuration scheme only.

Upgrades in the Cyclone III Device Family chapter.  
Design Security (Cyclone III LS Devices Only)  
Cyclone III LS devices offer design security features which play a vital role in the large  
and critical designs in the competitive military and commercial environments.  
Equipped with the configuration bit stream encryption and anti-tamper features,  
Cyclone III LS devices protect your designs from copying, reverse engineering and  
tampering. The configuration security of Cyclone III LS devices uses AES with 256-bit  
security key.
