A54SX08A-FTQG100

Overview

The A54SX08A-FTQG100 is an antifuse-based Field Programmable Gate Array from the SX-A family, manufactured by Microchip Technology. It features a capacity of 12,000 system gates and supports up to 81 user-programmable I/O pins within a 100-pin Thin Quad Flat Pack (TQFP) package. The device operates with supply voltages ranging from 2.25 V to 5.25 V and delivers system performance up to 250 MHz with internal clock frequencies reaching 350 MHz. Designed for industrial applications, it functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse technology for permanent configuration without external memory.
• Supports mixed-voltage operation including 2.5 V, 3.3 V, and 5 V I/O standards with 5 V input tolerance and drive strength.
• Hot-swap compliant I/Os allow insertion into active systems without degrading host reliability or requiring specific power sequencing.
• Includes dedicated boundary-scan testing capabilities compliant with IEEE Standard 1149.1 (JTAG) for diagnostic verification.

Applications

• Low-power, high-performance logic integration replacing complex CPLDs or gate arrays.
• Systems requiring deterministic timing and hot-swappable interface capabilities.
• Applications necessitating secure design protection against reverse engineering via FuseLock technology.

Procurement Notes

Verify the specific ordering suffix 'F' against official Microchip documentation to confirm speed grade and packaging details, as standard commercial grades typically use different suffixes. Ensure compatibility with Actel Designer software versions supporting the SX-A family. Confirm RoHS compliance status if required for your manufacturing process.

Selection Notes

Select this component when a nonvolatile FPGA architecture is preferred over volatile SRAM-based devices to eliminate configuration boot times. Consider the 12,000 system gate capacity and 81 I/O limit for moderate complexity designs. Verify that the TQFP-100 package fits the available PCB footprint and thermal constraints for the target industrial environment.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which are fabricated using 0.22 μm / 0.25 μm CMOS antifuse technology. The family offers various gate densities and package options, with the A54SX08A representing the entry-level density in the series. The SX-A line is characterized by its high-speed interconnect and robust security features inherent to antifuse architectures.

Replacement Considerations

Direct pin-compatible replacements within the same package and voltage profile include other speed grades of the A54SX08A, such as the A54SX08A-TQG100I. For higher capacity needs in the same package, consider the A54SX16A-1TQG100I, though logic resource mapping will differ significantly.
