A54SX16A-TQ100M

Overview

The A54SX16A-TQ100M is a Field Programmable Gate Array from the Microchip Technology SX-A family, featuring 24,000 system gates and 81 user-programmable I/Os. It utilizes 0.22 μm / 0.25 μm CMOS antifuse technology to deliver up to 250 MHz system performance and 350 MHz internal clock speeds. The device operates within a commercial temperature range of 0°C to +70°C and requires a supply voltage between 2.25 V and 2.75 V. Packaged in a 100-pin Thin Quad Flat Pack (TQFP), it supports mixed-voltage I/O standards including 2.5 V, 3.3 V, and 5 V with 5 V input tolerance.

Feature Summary

• Supports hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements.
• Provides deterministic timing through unique local routing resources like DirectConnect and FastConnect for predictable signal propagation.
• Includes Actel FuseLock security technology to prevent reverse engineering and unauthorized design access.

Applications

• High-performance logic integration replacing complex programmable logic devices
• Systems requiring nonvolatile single-chip solutions with no configuration bitstream interception
• Applications needing mixed-voltage operation with 5 V input tolerance

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as packaging suffixes may vary. Check for end-of-life notifications or production change notices prior to finalizing procurement plans.

Selection Notes

Select this model when 24,000 system gates and 81 I/Os are required in a 100-pin TQFP package. Ensure the design fits within the commercial temperature grade limits. Verify that the antifuse programming workflow aligns with the target manufacturing process.

Part Context

This part belongs to the SX-A family of FPGAs, which offers high-density logic in small packages. The A54SX16A variant provides a balance of capacity and pin count suitable for mid-range applications. The 'M' suffix indicates military-grade temperature capability, though the provided datasheet specifies commercial availability for this specific package combination.

Replacement Considerations

Direct replacements include other speed grades within the A54SX16A series such as A54SX16A-1TQ100M or A54SX16A-2TQ100M if higher performance is needed. Cross-family migration to newer Actel or Microchip FPGA architectures may be necessary for long-term supply assurance.
