A54SX16A-TQG100A

Overview

The A54SX16A-TQG100A is an automotive-grade Field Programmable Gate Array from the SX-A family, manufactured by Microchip Technology. It features a sea-of-modules architecture with 24,000 system gates and 81 user-programmable I/Os in a TQFP-100 package. The device operates on a 0.22µ CMOS process with a nominal supply voltage of 2.5 V (range 2.25 V to 2.75 V). It supports internal clock frequencies up to 250 MHz and includes 528 dedicated flip-flops. Operating temperature ranges from -40°C to +125°C.

Feature Summary

• Automotive-grade reliability with extended temperature support (-40°C to 125°C)
• Nonvolatile antifuse technology providing inherent design security
• Hot-swap compliant I/Os allowing safe insertion without power sequencing
• Deterministic timing with 100% pin-locking capability

Applications

• In-cabin telematics systems
• Automobile interconnect applications
• Performance-intensive logic integration replacing CPLDs

Procurement Notes

Verify the specific suffix 'A' confirms automotive grade qualification (-40°C to 125°C) and 'G' indicates lead-free packaging. Confirm RoHS compliance status through official datasheets or manufacturer declarations. Ensure the TQFP-100 package matches PCB footprint requirements. Check for moisture sensitivity levels and recommended reflow profiles during handling.

Selection Notes

Select this component when designing for automotive environments requiring operation up to 125°C. The 24,000 gate count suits moderate complexity logic designs. Verify that the 2.5 V core voltage aligns with system power rails. Consider the 81 available I/Os against interface requirements. Ensure the TQFP-100 package fits the mechanical constraints of the target assembly.

Part Context

This part belongs to the Actel SX-A Automotive Family FPGAs. It utilizes a sea-of-modules architecture optimized for fast signal propagation. The device integrates combinatorial and register cells within clusters. It supports IEEE 1149.1 boundary scan testing. The nonvolatile nature eliminates configuration bitstreams.

Replacement Considerations

Consult official Microchip/Actel documentation for qualified replacements. Cross-reference speed grades and temperature ranges. Verify package compatibility if substituting with other SX-A variants.
