A54SX32A-2TQ100I

Overview

The A54SX32A-2TQ100I is a Field Programmable Gate Array from the Microchip SX-A family, featuring 48,000 system gates and 2880 logic modules. 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 5.25 V and is housed in a 100-pin Thin Quad Flat Pack (TQFP) package. The industrial temperature grade (-40°C to +85°C) ensures reliable operation in demanding environments.

Feature Summary

• Supports mixed-voltage operation across 2.5 V, 3.3 V, and 5 V domains with 5 V input tolerance.
• Features hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements.
• Includes deterministic timing architecture with DirectConnect and FastConnect routing for predictable signal propagation.
• Integrates Actel Secure Programming Technology with FuseLock to prevent reverse engineering and design theft.

Applications

• 66 MHz PCI compliant interface integration
• High-performance state machine and counter logic implementation
• Secure single-chip nonvolatile programmable logic solutions

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature grade. Confirm RoHS compliance status as packaging options may vary. Check for any Product Change Notifications regarding assembly or material updates before finalizing procurement orders.

Selection Notes

Select this model for designs requiring 48,000 system gates with industrial temperature stability. Ensure the 100-pin TQFP footprint matches the PCB layout constraints. Verify that the 250 MHz speed grade meets the system timing requirements compared to faster or slower available grades.

Part Context

This component belongs to the Actel SX-A FPGA family, which utilizes metal-to-metal antifuse technology for permanent configuration. The series offers high-density logic resources with low power consumption, designed to replace multiple CPLDs or gate arrays in complex digital applications.

Replacement Considerations

Direct pin-compatible replacements are not explicitly listed in the provided documentation. Evaluate other A54SX32A variants with different speed grades or packages if form factor changes are permissible. Consult the manufacturer for end-of-life notifications or recommended next-generation upgrades.
