A54SX32A-FTQ144

Overview

The A54SX32A-FTQ144 is a Field Programmable Gate Array from the Microchip SX-A family, utilizing antifuse technology. It provides 48,000 system gates and supports up to 249 user-programmable I/O pins. The device operates with internal clock frequencies reaching 350 MHz and delivers 250 MHz system performance. It features three global clocks and supports mixed-voltage operation at 2.5 V, 3.3 V, and 5 V levels. The component is housed in a 144-pin Thin Quad Flat Pack (TQFP) package.

Feature Summary

• Nonvolatile single-chip solution using metal-to-metal programmable antifuse interconnect elements for permanent low-impedance connections.
• Supports hot-swap compliant I/Os allowing power-up/down without voltage sequencing requirements.
• Includes Silicon Explorer II for unique in-system diagnostic and verification capabilities.
• Compliant with IEEE Standard 1149.1 (JTAG) boundary-scan testing.

Applications

• 66 MHz PCI compliant designs
• High-performance state machines and fast counters
• Data path logic requiring deterministic timing

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm temperature grade and packaging compliance. Confirm current availability status as legacy components may have limited supply or discontinuation notices. Ensure design files are compatible with the required Actel Designer software version for programming.

Selection Notes

Select this model when 48,000 system gates and 249 I/Os are required within a 144-pin TQFP footprint. Consider the standard speed grade if higher frequency targets are not necessary. Verify that the application environment aligns with the commercial temperature range indicated by the blank application suffix.

Part Context

This component belongs to the SX-A family of FPGAs, which utilizes 0.22 μm / 0.25 μm CMOS antifuse technology. The family offers high-density logic modules arranged in a sea-of-modules architecture with dedicated routing resources like DirectConnect and FastConnect for optimized signal propagation.
