A54SX08A-FGG144I

Overview

The A54SX08A-FGG144I is a Field Programmable Gate Array from the Microsemi SX-A family, utilizing antifuse technology. It provides 12,000 system gates and 768 logic modules (CLBs). The device supports up to 111 user-programmable I/Os and features 3 global clock networks. It operates within an industrial temperature range of -40°C to +85°C and utilizes a 144-pin Fine Pitch Ball Grid Array package with a 1.0 mm pitch.

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.
• Features Actel Secure Programming Technology with FuseLock to prevent reverse engineering.

Applications

• 66 MHz PCI Compliant Single-Chip Solutions
• Deterministic User-Controllable Timing Applications
• Boundary-Scan Testing in Compliance with IEEE Standard 1149.1

Procurement Notes

Verify the specific ordering suffix 'FGG144I' against the manufacturer's current datasheet to confirm package type, speed grade, and temperature range. Ensure compatibility with existing PCB footprints for the 144-pin FBGA configuration. Confirm RoHS compliance status if required by local regulations.

Selection Notes

Select this component when a nonvolatile FPGA architecture is required to eliminate external configuration memory. Consider the 12,000 system gate capacity and 111 available I/Os for moderate complexity designs. Verify that the industrial temperature grade meets environmental constraints.

Part Context

This part belongs to the SX-A family of FPGAs, which are fabricated on 0.22 μm / 0.25 μm CMOS process technology. The family offers high-performance logic modules including register cells and combinatorial cells arranged in clusters and superclusters for optimal routing.

Replacement Considerations

Check the SX-A Product Profile table for alternative devices such as the A54SX16A or A54SX32A if higher gate counts are needed. Verify pinout compatibility across different packages like PQFP or TQFP if changing form factors.

FAQ

What is the maximum internal performance frequency of the A54SX08A?

The SX-A family devices support an internal performance of 350 MHz.

How does the DirectConnect feature improve performance?

DirectConnect provides a horizontal routing resource between a C-cell and its neighboring R-cell requiring no programmable interconnection, achieving a maximum routing delay of less than 0.1 ns.

Is the A54SX08A suitable for hot-swap applications?

Yes, the I/Os are configured to be hot-swappable, except for 3.3 V PCI configurations. During power-up/down, all I/Os are tristated.
