• Features hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing
• Includes deterministic timing architecture with DirectConnect and FastConnect routing resources
• Provides IEEE 1149.1 Boundary-Scan Testing compliance via JTAG interface

Applications

• High-speed controllers and address decoding
• Peripheral bus interfaces including PCI applications
• DSP and co-processor functions
• ASIC alternative designs requiring nonvolatile single-chip solutions

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm temperature grade and packaging details. Confirm current availability status as older FPGA families may have limited stock or end-of-life notifications. Ensure compatibility with existing PCB footprints for the PQFP-208 package before procurement.

Selection Notes

Select this device when design requirements include high-density logic within a moderate pin count footprint. Consider the SX-A family for applications needing robust security through antifuse technology and flexible I/O standards. Evaluate speed grades if timing constraints exceed standard performance levels.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which utilizes metal-to-metal programmable antifuse interconnect elements. The family offers a sea-of-modules architecture designed for optimal register and logic mixing. It serves as a cost-effective solution for integrating complex logic previously implemented in multiple CPLDs or PALs.

Replacement Considerations

Check for updated revisions within the A54SX16A series. Verify functional equivalence with other SX-A devices such as A54SX16P-2TQ144X79 if pin count reduction is acceptable.
