A54SX16A-TQ144A

Overview

The A54SX16A-TQ144A is an automotive-grade Field Programmable Gate Array (FPGA) from the SX-A family, manufactured by Microchip Technology. It features a sea-of-modules architecture with 24,000 system gates and 1,452 logic modules. The device supports up to 113 user-programmable I/O pins and includes dedicated flip-flops for sequential logic. It operates within an extended temperature range of -40°C to +125°C and utilizes a 0.22µ CMOS process technology. The FPGA offers internal performance capabilities up to 250 MHz and supports nonvolatile configuration via antifuse technology.

Feature Summary

• Automotive-grade reliability with extended temperature operation (-40°C to +125°C)
• Nonvolatile antifuse architecture providing inherent security against reverse engineering
• Hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing
• Deterministic timing with high-speed local routing resources like DirectConnect and FastConnect

Applications

• In-cabin telematics systems
• Automobile interconnect applications
• Performance-intensive embedded logic designs requiring deterministic timing

Procurement Notes

Verify the specific suffix 'A' indicates the automotive temperature grade (-40°C to +125°C) as defined in the ordering information. Confirm RoHS compliance status if required, noting that 'G' suffix denotes RoHS packaging while blank may indicate standard packaging. Check current product lifecycle status as automotive grades may have limited availability or end-of-life notifications.

Selection Notes

Select this component when designing for harsh automotive environments requiring wide temperature tolerance. Ensure the design fits within the 24,000 system gate capacity and 113 I/O limit. Consider the 250 MHz internal clock speed for performance requirements. Verify that the TQFP-144 package dimensions fit the PCB layout constraints.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which are known for their sea-of-modules architecture. The SX-A line bridges the gap between CPLDs and larger FPGAs, offering high density with low power consumption. The automotive variant ensures robustness for vehicle electronics, distinguishing it from commercial or industrial grades.

Replacement Considerations

Direct replacements within the same package and pinout include other A54SX16A variants with different speed grades or temperature ranges, such as A54SX16A-1TQ144 or A54SX16A-2TQ144, provided the electrical specifications meet the application needs. Cross-family migration to newer Microchip FPGA families requires significant redesign.
