A54SX32A-FBGG329

Overview

The A54SX32A-FBGG329 is a Field Programmable Gate Array from the Microchip SX-A family, utilizing antifuse technology. It features 48,000 system gates and 2,880 logic modules within a 329-pin Fine Pitch Ball Grid Array (FBGA) package. The device supports up to 249 user-programmable I/O pins and operates at a maximum frequency of 172 MHz. It functions with supply voltages between 2.25 V and 2.75 V and is rated for commercial temperature ranges.

Feature Summary

• Supports hot-swap capabilities and power-up/down friendly operation without voltage sequencing requirements.
• Provides deterministic timing through unique local routing resources including DirectConnect and FastConnect.
• Includes IEEE 1149.1 compliant boundary-scan testing and Actel Secure Programming Technology.

Applications

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

Procurement Notes

Verify the specific speed grade suffix associated with the FBGG329 package variant to ensure it meets the required timing constraints for your design. Confirm that the component matches the intended temperature grade, as the standard commercial grade covers 0°C to +70°C. Check for any relevant Product Change Notifications regarding manufacturing updates or packaging changes before finalizing procurement orders.

Selection Notes

Select this model when a high pin count in a compact BGA footprint is required alongside significant logic density. Ensure the design utilizes the available global clock networks effectively. Consider the nonvolatile nature of the antifuse architecture if reprogramming flexibility is not needed, as it offers inherent security against reverse engineering compared to volatile SRAM-based FPGAs.

Part Context

This component belongs to the SX-A family of FPGAs, which are fabricated using 0.22 μm / 0.25 μm CMOS antifuse technology. The family provides a cost-effective, low-power solution for integrating CPLD and FPGA functionality into a single chip. The A54SX32A specifically targets applications needing moderate logic capacity with high-speed performance.

Replacement Considerations
