A54SX32A-1TQ100M

Overview

The A54SX32A-1TQ100M is a Field Programmable Gate Array from the Microchip SX-A family, utilizing antifuse technology. It provides 48,000 system gates and 2,880 logic modules (CLBs). The device supports up to 2012 dedicated flip-flops and offers 81 user-programmable I/O pins. It operates within a voltage range of 2.25 V to 2.75 V for core supply and 2.5 V nominal. The component is housed in a 100-pin Thin Quad Flat Pack (TQFP) package. It features a maximum operating frequency of 278 MHz and functions reliably across an extended temperature range of -55°C to +125°C.

Feature Summary

• Supports mixed-voltage operation with configurable I/O standards including 3.3V/5V PCI, 5V TTL, and LVCMOS.
• 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

• High-performance digital logic integration requiring nonvolatile configuration
• Systems demanding hot-swappable interface capabilities
• Industrial or military applications requiring wide temperature grade stability

Procurement Notes

Verify the specific ordering suffix 'M' indicates the Military temperature grade (-55°C to +125°C) as defined in the official datasheet. Confirm RoHS compliance status separately, as standard packaging may differ from lead-free options. Ensure the TQFP-100 package dimensions match the target PCB footprint constraints before finalizing procurement orders.

Selection Notes

Select this model when 48,000 system gates are required alongside 81 available I/O pins. The -1 speed grade offers approximately 15% faster performance than the standard speed variant. Choose the M suffix specifically for military-grade environmental tolerance. Verify that the TQFP-100 package fits the assembly space compared to larger BGA alternatives if higher pin counts are needed.

Part Context

This component belongs to the Actel SX-A FPGA family, which utilizes metal-to-metal programmable antifuse interconnect elements. The SX-A series is designed for low-power, high-performance single-chip solutions. The A54SX32A designation specifically denotes the 48,000 system gate capacity within the product line hierarchy.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult Microchip Technology directly for current lifecycle status and potential obsolescence notifications regarding the A54SX32A series.
