A54SX08-2VQ100

Overview

The A54SX08-2VQ100 is a field-programmable gate array from the Actel SX-A family, fabricated using 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 12,000 system gates and supports up to 81 user I/Os in the 100-pin Thin Quad Flat Pack (TQFP) package. The device operates with internal clock frequencies up to 350 MHz and delivers 250 MHz system performance. It features three global clock networks and supports mixed-voltage I/O standards including 2.5 V, 3.3 V, and 5 V levels. The architecture utilizes metal-to-metal programmable antifuses for permanent interconnection.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal antifuse technology for deterministic timing and high reliability.
• Hot-swap compliant I/Os allowing insertion into active systems without power sequencing requirements.
• Configurable I/O support for multiple voltage standards including 3.3 V/5 V PCI, 5 V TTL, and 2.5 V LVCMOS2.
• Integrated boundary-scan testing capability compliant with IEEE Standard 1149.1 (JTAG).

Applications

• High-performance logic integration replacing complex programmable logic devices
• Systems requiring hot-swappable interface capabilities
• Applications needing deterministic timing with user-controllable delays
• Designs requiring secure programming with reverse-engineering protection

Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to confirm package type, speed grade, and temperature range. Ensure the component matches the required pin count and I/O configuration. Check for RoHS compliance status if environmental regulations apply. Confirm availability of the discontinued -3 speed grades if higher performance is needed, as they may no longer be produced.

Selection Notes

Select this device for designs requiring nonvolatile configuration without external memory. Consider the 100-pin TQFP package for space-constrained applications needing moderate I/O counts. Evaluate the -2 speed grade for approximately 25% faster performance compared to standard speed. Verify that the 3.3 V PCI I/O standard does not require hot-swap functionality, as it is an exception in the family.

Part Context

This part belongs to the Actel SX-A FPGA family, which offers a sea-of-modules architecture with dedicated flip-flops and combinatorial cells. The family ranges from 12,000 to 108,000 system gates. The A54SX08A variant represents the entry-level capacity within this series, providing a cost-effective solution for lower-complexity digital logic implementations while maintaining high-speed performance characteristics.
