A54SX32A-1TQ100I

Overview

The A54SX32A-1TQ100I is a Field Programmable Gate Array from the Microchip SX-A family, featuring 48,000 system gates and 1,800 CLBs. It operates at a maximum frequency of 250 MHz with an internal performance of 350 MHz. The device supports up to 81 user-programmable I/O pins and utilizes 0.22 μm / 0.25 μm CMOS antifuse technology. It functions within a voltage range of 2.25 V to 2.75 V and is housed in a 100-pin Thin Quad Flat Pack (TQFP) package.

Feature Summary

• Supports mixed-voltage operation for 2.5 V, 3.3 V, and 5 V I/Os with 5 V input tolerance
• Features hot-swap compliant I/Os allowing power-up/down without sequencing requirements
• Includes deterministic timing with user-controllable clock resources and boundary-scan testing compliance

Applications

• 66 MHz PCI compliant single-chip solutions
• High-performance logic integration replacing CPLDs or gate arrays
• Systems requiring secure programming and reverse engineering protection

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type, speed grade, and temperature range. Ensure compatibility with Actel Designer software versions for proper configuration and programming of the antifuse architecture.

Selection Notes

Select this model for designs requiring 48,000 system gates with industrial temperature stability. Consider the TQFP package constraints for PCB layout and verify that the 81 available I/O pins meet interface requirements. Confirm that the 250 MHz system performance aligns with the target application timing constraints.

Part Context

This component belongs to the SX-A family of FPGAs manufactured by Microchip Technology (formerly Actel). The SX-A series is characterized by its nonvolatile antifuse technology, which provides permanent interconnections and inherent security against reverse engineering compared to volatile SRAM-based FPGAs.

Replacement Considerations

Compatible alternatives within the same family include A54SX32A variants with different packages such as PQ208 or FBGA types, provided pin counts and resource requirements are met. Verify speed grades and temperature ranges when substituting.
