A54SX16-VQ100I

Overview

The A54SX16-VQ100I is a Field Programmable Gate Array from the Microsemi SX-A family, fabricated using 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 81 user-programmable I/O pins within a 100-pin Thin Quad Flat Pack (TQFP) package. It features three global clock networks and operates at maximum internal frequencies of 350 MHz with standard speed grades.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse interconnect elements for permanent low-impedance connections.
• Supports hot-swap compliant I/Os allowing power-up/down without voltage sequencing requirements.
• Includes dedicated routing resources such as DirectConnect and FastConnect for deterministic timing and high-speed signal propagation.
• Compliant with IEEE Standard 1149.1 (JTAG) for boundary-scan testing and in-system diagnostic verification.

Applications

• High-performance digital logic integration requiring deterministic timing
• Systems requiring nonvolatile configuration without external bitstream memory
• Hot-swappable interface designs with mixed-voltage I/O standards

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm temperature grade and packaging compliance. Confirm that the component matches the exact pin count and gate density specifications required for the target application design.

Selection Notes

Select this model based on the requirement for 24,000 system gates and 100-pin TQFP packaging. Ensure the design utilizes the available 81 user I/Os and leverages the three global clock networks provided by the SX-A architecture for optimal performance.

Part Context
