A54SX16A-2PQ208I

Overview

The A54SX16A-2PQ208I is a nonvolatile Field Programmable Gate Array from the Actel SX-A family, fabricated using 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 24,000 system gates and supports up to 175 user-programmable I/O pins in a 208-pin Plastic Quad Flat Pack (PQFP) package. The device operates within a commercial temperature range of 0°C to +70°C and utilizes a standard speed grade with a maximum internal performance frequency of 350 MHz. It features mixed-voltage I/O support for 2.5 V, 3.3 V, and 5 V standards.

Feature Summary

• Hot-swap compliant I/Os allow safe insertion into active systems without degrading host reliability.
• Power-up/down friendly architecture eliminates sequencing requirements for supply voltages.
• Supports 66 MHz PCI compliance alongside 5 V input tolerance and drive strength.
• Includes configurable weak-resistor pull-up or pull-down capabilities for deterministic power-up states.

Applications

• High-performance logic integration requiring deterministic timing
• Systems requiring hot-swappable interface capabilities
• Mixed-voltage digital designs supporting 3.3 V and 5 V standards

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type, speed grade, and temperature range. Ensure compatibility with existing PCB footprints for the 208-pin PQFP configuration. Confirm that the industrial temperature grade designation matches the operational environment requirements.

Selection Notes

Select this component when designing with the Actel SX-A family architecture. The -2 speed grade offers approximately 25% faster performance than the standard grade. Verify that the 208-pin PQFP package meets board space constraints and that the commercial temperature range aligns with the application's thermal specifications.
