A54SX32A-TQ144A

Overview

The A54SX32A-TQ144A 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 48,000 typical system gates and 2,880 logic modules. The device operates within a temperature range of -40°C to 125°C and utilizes a 0.22µ CMOS process technology. It supports up to 249 user-programmable I/O pins and includes dedicated flip-flops for sequential logic. The internal performance reaches 250 MHz, enabling complex logic execution in demanding environments.

Feature Summary

• Nonvolatile antifuse-based architecture providing deterministic timing and high security against reverse engineering
• Hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements
• Configurable I/O support for multiple voltage standards including 3.3V PCI, LVTTL, and LVCMOS2
• Integrated Boundary Scan Testing (BST) compliant with IEEE Standard 1149.1 for diagnostic verification

Applications

• In-cabin telematics systems requiring extended temperature operation
• Automobile interconnect applications needing reliable nonvolatile logic
• Performance-intensive designs replacing multiple CPLDs or gate arrays

Procurement Notes

Verify the specific speed grade suffix associated with the TQ144A package variant to ensure timing compliance for your design. Confirm RoHS compliance status through official Microchip documentation as packaging options may vary. Check for any recent Product Change Notifications regarding manufacturing updates or supply chain adjustments before finalizing procurement plans.

Selection Notes

Select this component when designing for automotive environments requiring operation up to 125°C. Ensure the design fits within the 48,000 system gate capacity and available I/O count. Consider the 0.22µ process technology constraints and verify that the required clock resources align with the two routed clocks and one hardwired clock available in this device size.

Part Context

This part belongs to the SX-A Automotive Family FPGAs, which are designed for harsh environments. The SX-A series offers a balance of high performance and low power consumption using antifuse technology. The TQ144A designation indicates a Thin Quad Flat Pack package with 144 pins, suitable for space-constrained automotive PCB layouts.

Replacement Considerations

Direct replacements within the same package and pinout include other A54SX32A variants with different speed grades or temperature ratings, such as A54SX32A-1TQ144A or A54SX32A-2TQ144A, provided the timing specifications meet the design requirements.
