A54SX32A-1BGG329

Overview

The A54SX32A-1BGG329 is a Field Programmable Gate Array from the Microchip Actel SX-A family, featuring 48,000 system gates and 2,880 logic modules. It supports up to 249 user-programmable I/O pins and utilizes a 0.22 μm / 0.25 μm CMOS antifuse process technology. The device operates at a standard speed grade with an internal performance of 350 MHz and a system performance of 250 MHz. It functions within a voltage range of 2.25 V to 2.75 V (nominal 2.5 V) and is housed in a 329-pin Plastic Ball Grid Array (PBGA) 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 sequencing requirements for supply voltages.
• Includes dedicated clock networks such as HCLK and routed clocks CLKA/KB for deterministic timing.
• Compliant with IEEE Standard 1149.1 (JTAG) for boundary-scan testing and diagnostic verification.

Applications

• 66 MHz PCI compliant designs
• Mixed-voltage systems supporting 2.5 V, 3.3 V, and 5 V operation
• High-performance state machines and fast counters

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm temperature grade and packaging compliance. Confirm availability status as older speed grades or packages may be discontinued. Ensure design tools support the SX-A architecture for proper place-and-route implementation.

Selection Notes

Select this component when a nonvolatile FPGA with high pin count and mixed-voltage I/O capability is required. Consider the 329-pin PBGA package constraints for PCB layout. Verify that the 249 I/O limit and 48,000 gate capacity meet the design complexity requirements compared to smaller or larger SX-A variants.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which are characterized by their antifuse technology and high-speed routing resources like DirectConnect and FastConnect. The family includes devices ranging from 12,000 to 108,000 system gates, offering various package options and temperature grades for diverse industrial and commercial applications.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Designers should consult Microchip Technology for current equivalent recommendations or migration paths from discontinued SX-A speed grades.
