A54SX16P-2TQG144I

Overview

The A54SX16P-2TQG144I is a Field Programmable Gate Array from the SX-A family, featuring 1452 Configurable Logic Blocks and 24,000 system gates. It operates at a maximum clock frequency of 320 MHz with a typical combinatorial delay of 0.7 ns. The device utilizes 0.22 μm / 0.25 μm CMOS antifuse technology and supports mixed-voltage I/O standards including 2.5 V, 3.3 V, and 5 V. It is housed in a 144-pin Thin Quad Flat Pack (TQFP) package and is rated for industrial temperature operation ranging from -40°C to +85°C.

Feature Summary

• Supports hot-swap compliant I/Os allowing insertion into active systems without power sequencing requirements.
• Provides deterministic timing through unique local routing resources like DirectConnect and FastConnect.
• Includes Actel Secure Programming Technology with FuseLock to prevent reverse engineering and design theft.

Applications

• High-performance digital logic integration requiring low latency
• Systems demanding nonvolatile single-chip FPGA solutions
• Industrial applications requiring robust boundary-scan testing capabilities

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type, speed grade, and temperature range. Ensure compatibility with existing PCB footprints for the TQFP-144 configuration. Confirm that the antifuse-based programming method aligns with your manufacturing workflow, as these devices are not reprogrammable once configured.

Selection Notes

Select this model when 24,000 system gates and 1452 CLBs are sufficient for the design complexity. The -2 speed grade offers approximately 25% faster performance than standard grades. Consider the TQFP-144 package if pin count and board space constraints favor thin quad flat pack configurations over ball grid arrays or plastic quad flat packs.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which are characterized by their metal-to-metal programmable antifuse interconnect technology. The SX-A series provides high-speed performance and security features suitable for cost-effective, low-power designs. The A54SX16 variant sits within the mid-range capacity of the family, offering a balance between resource density and execution speed.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided source material. Verify availability of alternative speed grades or packages within the same A54SX16A series if pinout compatibility allows.
