Chapter 1: Cyclone III Device Family Overview
Cyclone III Device Family Features
Design Security Feature
Cyclone III LS devices offer the following design security features:
■
Configuration security using advanced encryption standard (AES) with 256-bit
volatile key
Routing architecture optimized for design separation flow with the Quartus
®
II
software
■
■
Design separation flow achieves both physical and functional isolation
between design partitions
■
■
Ability to disable external JTAG port
Error Detection (ED) Cycle Indicator to core
■
■
Provides a pass or fail indicator at every ED cycle
Provides visibility over intentional or unintentional change of configuration
random access memory (CRAM) bits
■
Ability to perform zeroization to clear contents of the FPGA logic, CRAM,
embedded memory, and AES key
Internal oscillator enables system monitor and health check capabilities
■
Increased System Integration
■
■
High memory-to-logic and multiplier-to-logic ratio
High I/O count, low-and mid-range density devices for user I/O constrained
applications
■
■
Adjustable I/O slew rates to improve signal integrity
Supports I/O standards such as LVTTL, LVCMOS, SSTL, HSTL, PCI, PCI-X,
LVPECL, bus LVDS (BLVDS), LVDS, mini-LVDS, RSDS, and PPDS
Supports the multi-value on-chip termination (OCT) calibration feature to
eliminate variations over process, voltage, and temperature (PVT)
■
■
Four phase-locked loops (PLLs) per device provide robust clock management and
synthesis for device clock management, external system clock management, and
I/O interfaces
■
■
■
Five outputs per PLL
Cascadable to save I/Os, ease PCB routing, and reduce jitter
Dynamically reconfigurable to change phase shift, frequency multiplication or
division, or both, and input frequency in the system without reconfiguring the
device
■
■
Remote system upgrade without the aid of an external controller
Dedicated cyclical redundancy code checker circuitry to detect single-event upset
(SEU) issues
Nios
®
II embedded processor for Cyclone III device family, offering low cost and
custom-fit embedded processing solutions
