A54SX16A-2TQG100

Overview

The A54SX16A-2TQG100 is an antifuse-based Field Programmable Gate Array from the SX-A family, manufactured by Microchip Technology. It provides 24,000 system gates and 1,452 configurable logic blocks within a 100-pin Thin Quad Flat Pack (TQFP) package. The device supports up to 81 user-programmable I/O pins and features a maximum system performance of 250 MHz with internal clock frequencies reaching 350 MHz. It operates on a 0.22 μm / 0.25 μm CMOS process technology.

Feature Summary

• Supports hot-swap compliant I/Os allowing insertion into active systems without damage
• Features nonvolatile single-chip architecture eliminating configuration bitstream interception risks
• Includes dedicated boundary-scan testing compliance with IEEE Standard 1149.1 for diagnostic verification

Applications

• High-performance digital signal processing implementations
• Complex state machine designs requiring deterministic timing
• PCI-compliant interface solutions operating at 66 MHz

Procurement Notes

Verify the specific ordering suffix against official datasheets to confirm temperature grade and packaging compliance. Confirm that the -2 speed grade designation aligns with project timing requirements, as faster grades may have been discontinued. Ensure the TQFP-100 package dimensions match the target PCB footprint specifications before finalizing procurement orders.

Selection Notes

Select this component when 24,000 system gates are sufficient for the design complexity. The -2 speed grade offers approximately 25% faster performance than standard variants. Verify that the 100-pin TQFP package meets the available pin count requirements for the specific application interface needs.

Part Context

This part belongs to the Actel SX-A FPGA family, which utilizes metal-to-metal programmable antifuse interconnect elements. The series is characterized by high-density logic modules and low-power operation suitable for cost-effective integration of complex logic functions previously requiring multiple discrete components or gate arrays.

Replacement Considerations

Check for availability of the standard speed grade variant if the -2 speed designation is no longer supported. Consider higher capacity devices like the A54SX32A if additional logic resources are required in future revisions.
