A54SX16-2VQ100

Overview

The A54SX16-2VQ100 is a Field Programmable Gate Array from the Actel SX-A family, fabricated on 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 24,000 system gates and 1,452 configurable logic blocks (CLBs). The device supports up to 350 MHz internal performance with a maximum system frequency of 250 MHz. It features 81 user-programmable I/O pins in a 100-pin Thin Quad Flat Pack (TQFP) package. The core operates at 2.5 V, while I/O banks support mixed-voltage operation including 2.5 V, 3.3 V, and 5 V standards.

Feature Summary

• Supports hot-swappable I/O configurations for safe insertion into active systems without power sequencing requirements.
• Includes dedicated DirectConnect and FastConnect routing resources to minimize signal propagation delays within logic clusters.
• Features Actel FuseLock security technology to prevent reverse engineering and unauthorized design access.
• Provides IEEE 1149.1 compliant Boundary-Scan Testing capabilities for enhanced diagnostic and verification.

Applications

• High-performance digital logic integration replacing complex gate arrays
• PCI-compliant interface designs requiring 66 MHz bus speeds
• Secure embedded control applications utilizing nonvolatile antifuse architecture

Procurement Notes

Verify component authenticity through authorized Microchip or Actel distribution channels. Confirm that the specific ordering suffix matches the required speed grade and temperature range. Check for RoHS compliance status if environmental regulations apply to the target assembly process. Ensure proper handling procedures are followed due to moisture sensitivity classification.

Selection Notes

Select this model when 24,000 system gates and 100-pin TQFP packaging are required. The -2 speed grade offers approximately 25% faster performance than standard grades. Verify that the 2.5 V core voltage aligns with the system power budget. Consider the -F grade if slower switching speeds are needed to reduce electromagnetic interference.

Part Context

This component belongs to the Actel SX-A family of antifuse FPGAs, which utilizes metal-to-metal programmable interconnects. The family ranges from 12,000 to 108,000 system gates. The A54SX16 variant specifically targets mid-range capacity applications requiring deterministic timing and high-speed logic processing within a single-chip solution.

Replacement Considerations

Direct replacements include other A54SX16 variants with different packages such as A54SX16-2PQ208A or A54SX16-2TQ144. Speed grade adjustments may require selecting -1 or -3 grades, though some grades are discontinued. Cross-family migration to ProASIC3 or SmartFusion requires significant architectural redesign.
