A54SX16A-FG144A

Overview

The A54SX16A-FG144A is an automotive-grade Field Programmable Gate Array from the SX-A family, manufactured by Microsemi Corporation. It features a sea-of-modules architecture with 24,000 system gates and 1,452 logic modules. The device supports up to 180 user-programmable I/O pins and includes dedicated flip-flops for sequential logic. Operating within an extended temperature range of -40°C to 125°C, it utilizes a 0.22µ CMOS process technology. Key specifications include 250 MHz internal performance, hot-swap compliant I/Os, and support for 3.3V PCI, LVTTL, and LVCMOS2 standards.

Feature Summary

• Automotive-grade reliability with extended temperature operation (-40°C to 125°C)
• Nonvolatile antifuse architecture providing deterministic timing and high security
• Hot-swap compliant I/Os allowing safe insertion without power sequencing
• Integrated Boundary Scan Testing (BST) compliant with IEEE 1149.1

Applications

• In-cabin telematics systems
• Automobile interconnect applications
• Performance-intensive embedded control designs

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and lead-free status. Ensure the design accounts for the automotive temperature grade requirements. Confirm that the selected pinout matches the intended PCB layout constraints for the 144-pin Fine Pitch Ball Grid Array configuration.

Selection Notes

Select this component when designing for harsh automotive environments requiring nonvolatile logic. The SX-A architecture offers high resource utilization and 100% pin locking. Consider the available clock resources and I/O voltage levels (3.3V/2.5V) during the initial architecture phase to ensure compatibility with system peripherals.

Part Context

This part belongs to the Actel SX-A Automotive Family FPGAs, designed specifically for rugged applications. The SX-A line distinguishes itself through a sea-of-modules architecture that maximizes silicon efficiency. This family bridges the gap between CPLDs and gate arrays, offering faster time-to-market and lower power consumption for complex digital designs.

Replacement Considerations

Direct replacements within the same package and speed grade should be sought from the A54SX16A series. Verify temperature grades and I/O counts when considering adjacent devices like the A54SX08A or A54SX32A. Cross-family migration requires careful review of architectural differences and toolchain compatibility.
