A54SX08A-PQ208A

Overview

The A54SX08A-PQ208A is an automotive-grade Field Programmable Gate Array (FPGA) from the SX-A family, manufactured by Microsemi Corporation. It features a sea-of-modules architecture with 12,000 system gates, 768 logic modules, and 130 user-programmable I/Os in a 208-pin Plastic Quad Flat Pack (PQFP). The device operates on a 0.22µ CMOS process with internal clock frequencies up to 250 MHz. It supports supply voltages of 2.25V to 5.25V and functions within an extended temperature range of -40°C to 125°C.

Feature Summary

• Automotive-grade reliability with operation across -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 DirectConnect and FastConnect routing resources

Applications

• In-cabin telematics systems
• Automobile interconnect applications
• High-speed controllers and peripheral bus interfaces

Procurement Notes

Verify that the ordering suffix 'A' confirms the automotive temperature grade (-40°C to 125°C) and PQFP package type. Confirm RoHS compliance status based on the specific manufacturing lot or additional suffixes if required for your assembly process. Ensure the supplier provides documentation verifying the part originates from authorized Microsemi channels.

Selection Notes

Select this component when designing for harsh automotive environments requiring high-temperature stability. The 12,000 gate capacity suits moderate complexity logic designs. Consider the 208-pin PQFP package constraints regarding PCB space and thermal dissipation. Verify that the 130 available I/Os meet the interface requirements for the target application.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which utilizes a sea-of-modules architecture. The SX-A series was designed to replace multiple CPLDs and ASICs in performance-intensive applications. The A54SX08A variant represents the entry-level capacity within the 208-pin PQFP package options for the automotive grade lineup.

Replacement Considerations

Compatible alternatives within the same family include the A54SX16A-PQ208A and A54SX32A-PQ208A, which offer higher gate counts but maintain the same package and pinout compatibility.
