A54SX16A-TQG100

Overview

The A54SX16A-TQG100 is a Field Programmable Gate Array from the Microchip Technology SX-A family, featuring 24,000 system gates and 81 user-programmable I/O pins. It utilizes 0.22 μm / 0.25 μm CMOS antifuse technology to deliver 250 MHz system performance with an internal clock frequency of up to 350 MHz. The device operates within a voltage range of 2.25 V to 2.75 V at a nominal 2.5 V. Packaged in a 100-pin Thin Quad Flat Pack (TQFP), it supports mixed-voltage operation including 3.3 V and 5 V I/O standards with 5 V input tolerance.

Feature Summary

• Supports hot-swap compliant I/Os allowing insertion into active systems without power sequencing requirements.
• Provides nonvolatile single-chip configuration via metal-to-metal programmable antifuse interconnect elements.
• Enables deterministic timing through unique local routing resources such as DirectConnect and FastConnect.

Applications

• High-performance logic integration replacing complex CPLDs or gate arrays
• PCI-compliant interface designs requiring 66 MHz bus speeds
• Systems requiring secure, nonvolatile FPGA configuration

Procurement Notes

Verify the specific speed grade suffix associated with the part number, as standard speed variants exist alongside faster options. Confirm that the TQG100 designation corresponds to the lead-free RoHS compliant packaging variant if environmental compliance is required for the assembly process.

Selection Notes

Select this component when a design requires approximately 24,000 system gates with a 100-pin footprint. Ensure the application can accommodate the 2.5 V core voltage while utilizing the flexible I/O banks for 3.3 V or 5 V signaling levels. Verify that the commercial temperature range meets the operational environment requirements.

Part Context

This model belongs to the Actel SX-A family of FPGAs, which are characterized by their high-density antifuse architecture. The SX-A series offers a scalable range of logic capacities, positioning the A54SX16A as a mid-range solution suitable for applications demanding high speed and robust security features compared to earlier generation devices.

Replacement Considerations

Direct functional replacements within the same package and pinout include other speed grades of the A54SX16A series, such as the A54SX16A-1TQG100I or A54SX16A-2TQG100I, provided the timing specifications align with the design constraints.
