A54SX08-1VQ100I

Overview

The A54SX08-1VQ100I is an antifuse-based Field Programmable Gate Array (FPGA) from the Microsemi SX-A family. It provides 12,000 system gates and 768 logic modules. The device supports up to 81 user-programmable I/O pins and includes dedicated flip-flops for sequential logic. It operates within a voltage range of 2.25 V to 5.25 V and is rated for industrial temperatures between -40°C and +85°C. The component utilizes a 100-pin Thin Quad Flat Pack (TQFP) package with a 1.4 mm height.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse technology for permanent configuration without external memory.
• Supports mixed-voltage operation across 2.5 V, 3.3 V, and 5 V domains with 5 V input tolerance and drive strength capabilities.
• Features hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements.
• Includes boundary-scan testing compliance with IEEE Standard 1149.1 (JTAG) for diagnostic and verification purposes.

Applications

• Industrial control systems requiring deterministic timing and robust I/O configurations.
• Embedded applications needing secure, nonvolatile logic integration without boot-up configuration delays.
• Systems supporting mixed-voltage interfaces including 3.3 V/5 V PCI and 5 V TTL standards.

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature grade. Confirm RoHS compliance status as standard packaging may differ from lead-free variants. Check current availability as this series may have limited production runs or end-of-life status.

Selection Notes

Select this model for designs requiring 12,000 system gates with a 100-pin footprint. Ensure the design accommodates the 2.25 V to 5.25 V supply range. Verify that the TQFP package dimensions fit the PCB layout constraints. Consider the -1 speed grade performance relative to standard grades if timing closure is critical.

Part Context

This component belongs to the Actel/Microsemi SX-A family of FPGAs, which are distinguished by their antifuse programming technology. Unlike volatile SRAM-based FPGAs, these devices retain configuration data without power, simplifying system architecture by eliminating external configuration flash memory.

Replacement Considerations

Cross-reference with other A54SX08A variants in different packages such as PQFP or FBGA if pin count compatibility allows. Verify speed grade equivalence (-1 vs Standard) when substituting. Note that newer Microchip FPGA families may require significant architectural redesign rather than direct pin-for-pin replacement.
