A54SX16A-1PQG208I

Overview

The A54SX16A-1PQG208I is a nonvolatile Field Programmable Gate Array from the 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/Os within a 208-pin Plastic Quad Flat Pack (PQFP) package. The device operates at an industrial temperature range of -40°C to +85°C with a speed grade of -1, offering approximately 15% faster performance than standard speed grades. It features three global clock networks and supports mixed-voltage operation for 2.5 V, 3.3 V, and 5 V I/O standards.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse interconnect elements for permanent low-impedance connections.
• Hot-swap compliant I/Os that tristate during power-up/down without requiring supply voltage sequencing.
• Configurable I/O modules supporting multiple standards including 3.3 V/5 V PCI, 5 V TTL, 3.3 V LVTTL, and 2.5 V LVCMOS2.
• Deterministic timing architecture featuring DirectConnect and FastConnect routing resources for predictable signal propagation.

Applications

• High-performance logic integration replacing complex programmable logic devices (CPLDs).
• Systems requiring deterministic timing and concurrent printed circuit board development.
• Applications necessitating hot-swappable interface capabilities and mixed-voltage operation.

Procurement Notes

Verify component authenticity through official Microchip Technology channels or authorized distributors. Confirm the specific ordering suffix matches the required speed grade (-1), package type (PQFP), and temperature range (Industrial). Ensure compliance with relevant environmental regulations such as RoHS status if applicable to the specific manufacturing batch.

Selection Notes

Select this model when 24,000 system gates and 175 user I/Os are sufficient for the design requirements. The -1 speed grade is appropriate for applications needing higher performance than standard grades but not the fastest available options. Verify that the PQFP package fits the PCB footprint constraints and that the industrial temperature range meets the operational environment specifications.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which was acquired by Microchip Technology. The SX-A series is characterized by its high-density antifuse technology and unique 'sea-of-modules' architecture. This specific part represents a mid-range capacity device within the family, balancing logic density with pin count for versatile digital logic applications.

Replacement Considerations

Direct replacements within the same package and pinout include other speed grades of the A54SX16A series, such as the Standard Speed version (A54SX16A-PQG208I) or faster grades like -2 (A54SX16A-2PQG208I). Cross-family migration to newer Microchip FPGA architectures requires schematic and software redesign due to architectural differences.
