• Includes deterministic routing resources such as DirectConnect and FastConnect for predictable timing.
• Features Actel FuseLock security technology to prevent reverse engineering and unauthorized access.

Applications

• High-performance digital signal processing
• Complex state machine implementations
• PCI-compliant interface designs

Procurement Notes

Verify the exact ordering suffix against official documentation to confirm temperature grade and packaging specifications. Confirm current availability status as older speed grades may be discontinued or subject to manufacturing changes.

Selection Notes

Select this model for applications requiring high-speed logic with deterministic performance characteristics. Ensure the design utilizes the available global clock networks and verify that the required I/O standards are compatible with the supported voltage levels.

Part Context

This component belongs to the SX-A family of FPGAs, which utilize metal-to-metal programmable antifuse interconnect elements. The architecture is designed to provide optimal register-to-logic ratios and high-density routing capabilities within a single-chip solution.

FAQ

How does the DirectConnect feature improve performance?

DirectConnect provides a hardwired horizontal routing resource between C-cells and neighboring R-cells within a SuperCluster, achieving a maximum routing delay of less than 0.1 ns without using programmable antifuses.

What is the behavior of I/Os during power-up?

During power-up or down, all I/Os are tristated by default. The device allows VCCA and VCCI to be powered in any order, and individually selectable pull-ups or pull-downs can be configured to ensure a known state.
