A54SX32A-2FG144

Overview

The A54SX32A-2FG144 is a Field Programmable Gate Array from the SX-A family, featuring 48,000 system gates and 2,880 logic modules. It operates at a maximum clock frequency of 250 MHz with an internal performance of 350 MHz. The device utilizes 0.22 μm / 0.25 μm CMOS antifuse technology and supports mixed-voltage I/Os for 2.5 V, 3.3 V, and 5 V applications. It is housed in a 144-pin Fine Pitch Ball Grid Array (FBGA) package with a 1.0 mm pitch. The component supports up to 111 user-programmable I/O pins and includes three global clocks.

Feature Summary

• Supports hot-swap compliant I/Os allowing operation during power-up/down without voltage sequencing requirements
• Features deterministic timing through metal-to-metal programmable antifuse interconnect elements
• Includes boundary-scan testing capabilities compliant with IEEE Standard 1149.1 (JTAG)
• Provides secure programming technology to prevent reverse engineering and design theft

Applications

• 66 MHz PCI compliant single-chip solutions
• High-performance digital signal processing designs
• Complex state machine implementations requiring fast counters
• Data path logic integration replacing multiple CPLDs

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm temperature grade and packaging compliance. Ensure the selected variant matches the required operating environment specifications before procurement. Cross-reference the part number with current datasheet revisions to validate availability status.

Selection Notes

Select this model when 48,000 system gates and 250 MHz performance are required within a compact 144-pin footprint. Consider the FBGA package for high-density board layouts. Verify that the -2 speed grade meets the target timing constraints compared to standard or faster alternatives.

Part Context

This component belongs to the Actel SX-A FPGA family, which utilizes nonvolatile antifuse technology. The SX-A series provides a cost-effective solution for low-power, high-performance designs by integrating complex logic functions into a single chip. The architecture emphasizes optimal register-to-logic mixing and fast routing resources.

Replacement Considerations

Compatible variants within the same package include A54SX32A-1FG144 and A54SX32A-FG144. These parts share the same physical footprint but differ in speed grades. Verify electrical characteristics and timing parameters to ensure functional equivalence in the target application.
