A54SX16A-1TQ144

Overview

The A54SX16A-1TQ144 is a Field Programmable Gate Array from the SX-A family, manufactured by Microchip Technology. It features 24,000 system gates and 1,452 logic modules within a 144-pin Thin Quad Flat Pack (TQFP) package. The device supports up to 113 user-programmable I/O pins and operates with a nominal supply voltage of 2.5 V, ranging from 2.25 V to 2.75 V. It delivers a maximum system performance frequency of 263 MHz and an internal performance frequency of 350 MHz. The component is designed for commercial temperature applications, functioning reliably between 0°C and +70°C.

Feature Summary

• Utilizes nonvolatile antifuse technology for permanent configuration without external memory.
• Supports hot-swap capabilities allowing insertion into active systems without damage.
• Enables mixed-voltage operation across 2.5 V, 3.3 V, and 5 V standards with 5 V input tolerance.
• Provides deterministic timing through dedicated routing resources like DirectConnect and FastConnect.

Applications

• High-speed data path logic and fast counters
• State machine implementations requiring predictable timing
• PCI compliant interface designs operating at 66 MHz
• Systems requiring secure, single-chip nonvolatile solutions

Procurement Notes

Verify the specific speed grade suffix '1' corresponds to the required performance level, as it indicates approximately 15% faster operation than standard speed. Confirm that the TQFP package dimensions align with the target PCB footprint. Ensure the design accounts for the commercial temperature range limits during thermal analysis.

Selection Notes

Select this part when 24,000 system gates are sufficient for the logic density requirements. Consider the 144-pin TQFP package if leaded surface-mount assembly is preferred over ball grid array options. Verify that the 113 available I/O pins meet the interface count needs, noting that clock buffers consume some of these pins.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which were originally developed by Actel Corporation before being acquired by Microsemi and subsequently Microchip Technology. The SX-A series is characterized by its metal-to-metal antifuse interconnect architecture, offering high performance and security compared to volatile SRAM-based FPGAs.

Replacement Considerations

Direct replacements within the same package and pinout include other speed grades of the A54SX16A series, such as the Standard or -2 variants, provided timing constraints allow. Cross-family migration to newer Microchip PolarFire or Igloo devices requires significant schematic and code redesign due to architectural differences.
