A54SX08A-1TQG100

Overview

The A54SX08A-1TQG100 is a nonvolatile FPGA from the Microchip SX-A family, featuring 12,000 system gates and 768 logic modules. It utilizes 0.22 μm / 0.25 μm CMOS antifuse technology for permanent configuration. The device operates within a supply voltage range of 2.25 V to 5.25 V and supports mixed-voltage I/O standards including 3.3 V PCI, 5 V TTL, and 2.5 V LVCMOS2. It provides up to 81 user-programmable I/Os in a 100-pin Thin Quad Flat Pack (TQFP) package. The industrial temperature grade (-40°C to +85°C) ensures reliable operation in demanding environments.

Feature Summary

• Nonvolatile single-chip solution using metal-to-metal programmable antifuse interconnect elements
• Supports hot-swap capabilities with flexible power-up/down sequencing requirements
• Includes Silicon Explorer II for unique in-system diagnostic and verification
• Compliant with IEEE Standard 1149.1 (JTAG) boundary-scan testing

Applications

• Low-power, high-performance embedded logic designs
• Systems requiring deterministic timing and pin-locking
• Industrial control applications operating in extended temperature ranges

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type, speed grade, and temperature rating. Confirm RoHS compliance status as packaging options may vary. Ensure the source document matches the exact part number to validate technical specifications before procurement.

Selection Notes

Select this component for designs requiring nonvolatile configuration without external memory. Verify that the 12,000 system gate capacity meets logic density requirements. Check if the -1 speed grade performance aligns with system timing constraints. Ensure the TQFP package fits the available PCB footprint.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which are characterized by their antifuse-based architecture. The SX-A series offers high performance and low power consumption, serving as a cost-effective alternative to volatile FPGAs or complex CPLDs. The A54SX08A represents the entry-level capacity within this specific product line.

Replacement Considerations

Cross-reference with other A54SX08A variants sharing the same TQFP-100 package but differing in speed grades or temperature ratings. Verify compatibility with existing design software tools when substituting speed grades.
