A54SX32A-FG144A

Overview

The A54SX32A-FG144A is an automotive-grade Field Programmable Gate Array from the SX-A family, manufactured by Microsemi. It features a sea-of-modules architecture with 48,000 typical system gates and 2,880 logic modules. The device operates within an extended temperature range of -40°C to 125°C and utilizes a 0.22µ CMOS process technology. It supports up to 111 user-programmable I/Os in a 144-pin Fine Pitch Ball Grid Array package. Key electrical specifications include support for 3.3V PCI, 3.3V LVTTL, and 2.5V LVCMOS2 standards, with internal clock frequencies reaching 250 MHz.

Feature Summary

• Automotive-grade reliability with operation across -40°C to 125°C temperature ranges
• Nonvolatile antifuse architecture providing deterministic performance and high security against reverse engineering
• Hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements
• Integrated Boundary Scan Testing (BST) compliant with IEEE Standard 1149.1 for diagnostic verification

Applications

• In-cabin telematics systems
• Automobile interconnect applications
• Performance-intensive embedded logic designs requiring automotive qualification

Procurement Notes

Verify that the specific ordering suffix corresponds to the required temperature grade and packaging configuration. Confirm RoHS compliance status if environmental regulations apply to the target assembly. Ensure the design toolchain supports the SX-A family architecture for proper synthesis and place-and-route implementation.

Selection Notes

Select this component when designing for harsh automotive environments requiring extended temperature stability. The SX-A architecture offers high logic density relative to pin count, suitable for complex state machines and datapath logic. Consider the nonvolatile nature of the device for applications where configuration retention is critical without external memory.

Part Context

This part belongs to the Actel SX-A Automotive Family, which extends the commercial SX-A line with qualified temperature ranges. The family includes variants like A54SX08A, A54SX16A, and A54SX72A, offering scalable gate counts. The FG144A designation indicates the 144-pin FBGA package option within this specific automotive-grade series.

Replacement Considerations

Direct replacements within the same package and pinout include other speed grades or capacity variants of the SX-A family, such as A54SX16A-FG144A or A54SX72A-FG144A, provided timing and resource requirements are met. Cross-family migration to newer Microchip FPGA architectures requires significant redesign.
