A54SX16-VQG100

Overview

The A54SX16-VQG100 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 1,452 Configurable Logic Blocks (CLBs) and 24,000 system gates. The device supports up to 81 user-programmable I/O pins and features dedicated flip-flops for sequential logic. It operates within a commercial temperature range of 0°C to +70°C and utilizes a VQFP-100 package.

Feature Summary

• Supports mixed-voltage operation with configurable I/O standards including 3.3V/5V PCI, 5V TTL, 3.3V LVTTL, and 2.5V LVCMOS2.
• Features hot-swap compliant I/Os that allow safe insertion into active systems without power sequencing requirements.
• Includes boundary-scan testing capabilities compliant with IEEE Standard 1149.1 (JTAG) for diagnostic verification.

Applications

• High-performance digital logic integration requiring deterministic timing
• PCI-compliant interface designs operating at standard bus speeds
• Systems requiring nonvolatile single-chip FPGA solutions

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature grade. Confirm RoHS compliance status as legacy variants may differ. Check for end-of-life notifications or discontinuance notices prior to finalizing procurement plans.

Selection Notes

Select this component when a design requires approximately 24,000 system gates with a 100-pin footprint. Ensure the application fits within the commercial temperature range limits. Verify that the required I/O voltage levels match the supported standards listed in the electrical specifications.

Part Context
