A54SX32A-2FGG144

Overview

The A54SX32A-2FGG144 is a Field Programmable Gate Array from the SX-A family, featuring 48,000 system gates and 2,880 logic modules. It operates with a maximum system frequency of 250 MHz and an internal performance of 350 MHz. The device utilizes 0.22 μm / 0.25 μm CMOS antifuse technology and supports mixed-voltage I/O standards including 2.5 V, 3.3 V, and 5 V. It is housed in a 144-pin Fine Pitch Ball Grid Array (FBGA) package with a 1.0 mm pitch.

Feature Summary

• Supports hot-swap compliant I/Os allowing power-up/down without sequencing requirements
• Provides deterministic timing through user-controllable clock resources and routing
• Includes boundary-scan testing compliance with IEEE Standard 1149.1 (JTAG)
• Features Actel Secure Programming Technology to prevent reverse engineering

Applications

• 66 MHz PCI compliant single-chip solutions
• High-performance digital signal processing
• Complex state machine implementations
• Data path logic integration

Procurement Notes

Verify the specific speed grade suffix '2' indicates approximately 25% faster performance than standard. Confirm the 'G' suffix denotes RoHS compliant packaging. Ensure the FBGA144 package matches the target PCB footprint. Check for industrial temperature range availability if operating outside commercial limits.

Selection Notes

Select this model for designs requiring 48,000 system gates with high-speed performance. The -2 speed grade offers faster switching than standard variants. Verify that the 144-pin FBGA package fits the board space constraints. Consider the mixed-voltage I/O capabilities for interfacing with different logic families.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which are known for their nonvolatile antifuse architecture. The SX-A series provides a cost-effective solution for integrating CPLD and FPGA functionalities into a single chip. It is designed for applications demanding low power consumption and high reliability.

Replacement Considerations

Direct replacements within the same package and pinout include other speed grades of the A54SX32A series, such as the standard or -1 speed variants. Cross-family migration may require retiming and resource verification due to architectural differences between antifuse and SRAM-based FPGAs.
