A54SX16P-1TQ144

Overview

The A54SX16P-1TQ144 is a Field Programmable Gate Array from the Actel SX-A family, fabricated on 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 24,000 system gates and 1,452 logic modules (combinatorial cells). The device features up to 113 user-programmable I/Os and supports mixed-voltage operation at 2.5 V, 3.3 V, and 5 V with 5 V input tolerance. Operating within a commercial temperature range of 0°C to +70°C, it utilizes a TQFP-144 package. The architecture delivers deterministic timing with internal clock frequencies up to 350 MHz.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse interconnect elements for permanent low-impedance connections.
• Supports hot-swap compliant I/Os allowing power-up/down in any order without supply voltage sequencing requirements.
• Includes dedicated routing resources such as DirectConnect and FastConnect to minimize signal propagation delays.
• Features IEEE 1149.1 (JTAG) boundary-scan testing compliance with configurable Dedicated or Flexible modes.

Applications

• High-performance digital logic integration requiring deterministic timing
• Systems requiring nonvolatile configuration without external bitstream memory
• Hot-swappable hardware interfaces and cold-sparing applications

Procurement Notes

Verify component authenticity through authorized Microchip distributors. Confirm that the ordering suffix matches the specific speed grade and temperature range required for the application environment. Ensure proper handling procedures are followed due to moisture sensitivity classification.

Selection Notes

Select this model when 24,000 system gates and 113 I/Os are sufficient for the design. The 'P' indicates Plastic Quad Flat Pack packaging, while '1' denotes the standard speed grade. Verify that the 0°C to +70°C commercial temperature range meets operational requirements.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which are designed for cost-effective, low-power, high-performance designs. The family utilizes antifuse technology to provide secure, nonvolatile programming capabilities suitable for embedded control and interface applications.

Replacement Considerations

Compatible alternatives within the same family include A54SX16A-1TQ144 (Commercial temp) and A54SX16A-2TQ144 (Industrial temp). Note that speed grades -3 have been discontinued.
