A54SX32A-TQG100A

Overview

The A54SX32A-TQG100A 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 48,000 system gates and 2,880 logic modules. The device operates within a supply voltage range of 2.25 V to 2.75 V at a nominal 2.5 V. It supports up to 81 user-programmable I/Os and includes dedicated flip-flops for sequential logic. The component is housed in a 100-pin Thin Quad Flat Pack (TQFP) package and is rated for an extended operating temperature range from -40°C to +125°C.

Feature Summary

• Automotive-grade reliability with extended temperature support (-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 logic designs requiring nonvolatile configuration

Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm RoHS compliance status as it varies by manufacturing batch. Ensure the design tool version supports the SX-A family for proper synthesis and place-and-route operations before finalizing procurement.

Selection Notes

Select this model when an automotive-qualified FPGA with nonvolatile configuration is required. The TQFP-100 package is suitable for space-constrained PCB layouts. Consider the 48K gate capacity and 81 I/O limit against design complexity. Verify that the 2.5V core voltage aligns with the target system's power distribution network.

Part Context

This component belongs to the Actel SX-A Automotive Family, which utilizes a sea-of-modules architecture optimized for low power and high performance. The SX-A series is designed to replace multiple CPLDs or ASICs in automotive environments, offering a single-chip solution with built-in security features like FuseLock to prevent reverse engineering.

Replacement Considerations

Direct pin-to-pin replacements within the same package are limited due to specific speed grades and temperature ratings. Other members of the A54SX32A series, such as A54SX32A-1TQG100 or A54SX32A-FGG256A, may share architectural similarities but differ in speed, package, or temperature specifications.
