A54SX08A-1TQG144

Overview

The A54SX08A-1TQG144 is a Field Programmable Gate Array from the SX-A family, manufactured by Microchip Technology. It features 12,000 system gates and 768 logic modules (CLBs). The device provides 113 user-programmable I/Os and supports up to 2,012 dedicated flip-flops. It operates with a supply voltage range of 2.25 V to 5.25 V and achieves a maximum system performance frequency of 250 MHz with internal clock speeds up to 350 MHz. The component is housed in a 144-pin Thin Quad Flat Pack (TQFP) package and is rated for an industrial operating temperature range of -40°C to +85°C.

Feature Summary

• Utilizes nonvolatile antifuse technology for permanent configuration without external memory
• Supports mixed-voltage I/O standards including 2.5 V, 3.3 V, and 5 V with 5 V input tolerance
• Features hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing
• Includes deterministic timing architecture with DirectConnect and FastConnect routing resources

Applications

• High-performance digital signal processing implementations
• Interface bridging between disparate voltage domains
• Prototyping complex logic designs requiring nonvolatile storage
• Industrial control systems requiring hot-swappable capabilities

Procurement Notes

Verify the specific speed grade suffix '1' corresponds to the required timing constraints for your design. Confirm that the TQG144 package variant matches your PCB footprint requirements. Ensure the industrial temperature grade meets environmental specifications. Check current availability status as legacy antifuse products may have limited production runs.

Selection Notes

Select this model when a nonvolatile FPGA solution is required to eliminate configuration boot times. Choose the A54SX08A variant if the design requires approximately 12,000 system gates. Opt for the -1 speed grade if higher performance than the standard grade is needed but full military or automotive grades are not required. Verify that the 144-pin TQFP package fits within the available board space constraints.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which were originally developed by Actel Corporation before being acquired by Microsemi and subsequently Microchip Technology. The SX-A series is characterized by its use of metal-to-metal antifuse interconnects, providing high-speed performance and inherent security against reverse engineering compared to volatile SRAM-based FPGAs.

Replacement Considerations

Direct pin-compatible replacements within the same package and speed grade are limited due to the discontinuation of the SX-A line. Consider migrating to Microchip's IGLOO2 or PolarFire families for modern equivalents, though these require significant schematic and layout redesigns.
