A54SX16P-VQ100I

Overview

The A54SX16P-VQ100I is a Field Programmable Gate Array from the Actel SX-A family, featuring 24,000 system gates and 81 user I/Os. It operates within an industrial temperature range of -40°C to +85°C and supports mixed-voltage operation at 2.5 V, 3.3 V, and 5 V. The device utilizes antifuse technology for nonvolatile configuration and includes hot-swap compliant I/Os with individually selectable slew rates and power-up resistors.

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 that tristate during power-up/down without requiring supply sequencing.
• Includes configurable weak-resistor pull-up or pull-down capabilities for deterministic power-up states.

Applications

• Hot-swappable systems requiring safe insertion into electrically active backplanes
• Industrial control applications operating in extended temperature environments
• Mixed-voltage interface designs connecting disparate logic levels

Procurement Notes

Verify component authenticity through authorized Microchip Technology channels. Confirm RoHS compliance status and check for Product Change Notifications regarding manufacturing updates. Ensure storage conditions meet moisture sensitivity level requirements prior to assembly.

Selection Notes

Select this part for designs requiring nonvolatile FPGA resources with high-speed performance. Verify that the 81 available I/O pins satisfy interface requirements. Confirm compatibility with Actel Designer software tools for place-and-route implementation.

Part Context

This component belongs to the Actel SX-A family of antifuse FPGAs. It provides a single-chip solution combining high-performance logic with security features like FuseLock technology to prevent reverse engineering. The architecture utilizes metal-to-metal programmable interconnect elements for low-impedance connections.

Replacement Considerations

Consult official Microchip documentation for verified cross-reference part numbers. Do not substitute based on generic pin counts alone; verify specific speed grades, package dimensions, and voltage tolerances against the original design specifications.
