A54SX08A-TQ100

Overview

The A54SX08A-TQ100 is a nonvolatile Field Programmable Gate Array from the Microchip Actel SX-A family, fabricated using 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 12,000 system gates and supports up to 81 user-programmable I/O pins within a 100-pin Thin Quad Flat Pack (TQFP) package. The device operates at a standard speed grade with internal clock frequencies reaching 350 MHz. It features three global clock networks and supports mixed-voltage operation across 2.5 V, 3.3 V, and 5 V domains with 5 V input tolerance.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse interconnect elements for permanent configuration without external memory.
• Hot-swap compliant I/O architecture allowing safe insertion into electrically active systems without degrading host reliability or requiring specific power sequencing.
• Configurable I/O modules supporting multiple voltage standards including 3.3 V/5 V PCI, 5 V TTL, 3.3 V LVTTL, and 2.5 V LVCMOS2 with individually selectable slew rates.

Applications

• High-performance logic integration replacing complex CPLDs or gate arrays in cost-sensitive designs
• Systems requiring deterministic timing and hot-swappable interface capabilities
• Applications needing secure, nonvolatile configuration with protection against reverse engineering

Procurement Notes

Verify the specific ordering suffix to confirm temperature grade and packaging compliance. The base model indicates a commercial temperature range; industrial or automotive variants require distinct suffixes. Confirm RoHS status and lead-free packaging requirements against current manufacturing specifications before procurement.

Selection Notes

Select this component for designs requiring 12,000 system gates with a 100-pin footprint. Ensure the design utilizes the available 81 I/Os and three global clocks. Verify that the target application does not exceed the standard speed grade limitations or requires the discontinued -3 speed grade options.

Part Context

This part belongs to the Actel SX-A FPGA family, which offers high-density logic in small packages. The A54SX08A variant represents the entry-level capacity within the series, providing 12,000 system gates. It shares architectural features like DirectConnect and FastConnect routing with larger devices such as the A54SX16A and A54SX32A.

Replacement Considerations

Direct pin-compatible replacements within the same package are limited due to the discontinuation of certain speed grades. Consider the A54SX08A-1TQ100I for industrial temperature ranges or higher speed performance. Cross-family migration to newer Actel or third-party FPGAs may be necessary for long-term supply assurance.
