A54SX16A-TQ100A

Overview

The A54SX16A-TQ100A 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 typical system gates and 1,452 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 81 user-programmable I/O pins in a 100-pin Thin Quad Flat Pack (TQFP) package. Key electrical specifications include a maximum internal clock frequency of 250 MHz and support for mixed-voltage I/O standards including 3.3V PCI, 3.3V LVTTL, and 2.5V LVCMOS2.

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 system damage
• Integrated boundary-scan testing (JTAG) and internal probing capabilities

Applications

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

Procurement Notes

Verify the specific ordering suffix 'G' for RoHS compliance status against current manufacturer documentation. Confirm that the automotive grade designation ensures guard-banded specifications rather than direct extended temperature testing. Ensure design tools support the TQFP-100 package variant for accurate pin mapping.

Selection Notes

Select this component when designing for harsh automotive environments requiring nonvolatile configuration and high-speed logic processing. The 100-pin TQFP package offers a compact solution for designs needing approximately 24,000 system gates. Consider the 250 MHz internal performance capability for complex state machines or datapath logic integration.

Part Context

This part belongs to the Actel SX-A Automotive Family, which expands the standard commercial SX-A line to meet automotive thermal requirements. The A54SX16A variant provides a mid-range capacity within the family, bridging the gap between the smaller A54SX08A and larger A54SX32A devices in terms of gate count and I/O availability.

Replacement Considerations

Direct replacements must match the automotive temperature grade and TQFP-100 package. Verify compatibility with existing layout tools and ensure the substitute supports the same I/O voltage standards and JTAG interface requirements.
