A54SX16P-TQG144I

Overview

The A54SX16P-TQG144I 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 24,000 typical system gates and 1,452 logic modules (CLBs). The device supports up to 350 MHz internal performance and features 113 user-programmable I/Os in a 144-pin Thin Quad Flat Pack (TQFP) package. It operates within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Supports mixed-voltage operation with configurable I/O standards including 3.3 V/5 V PCI, 5 V TTL, 3.3 V LVTTL, and 2.5 V LVCMOS2.
• Features hot-swap compliant I/Os that allow safe insertion into active systems without power sequencing requirements.
• Includes dedicated clock resources such as HCLK, CLKA, and CLKB for deterministic timing control.
• Provides IEEE 1149.1 (JTAG) boundary-scan testing capabilities for in-system diagnostic verification.

Applications

• High-performance digital signal processing
• Industrial automation controllers
• Communication interface protocols

Procurement Notes

Verify the specific ordering suffix 'I' confirms the industrial temperature grade (-40°C to +85°C) and the 'P' indicates the Plastic TQFP package type. Confirm RoHS compliance status through official Microchip documentation as packaging options vary by manufacturing lot.

Selection Notes

Select this component when designs require nonvolatile configuration without external memory chips. Ensure the 144-pin TQFP footprint matches the PCB layout constraints. Verify that the 24,000 gate capacity meets the logic density requirements compared to smaller SX-A variants like the A54SX08A.

Part Context

This part belongs to the Actel SX-A FPGA family, which utilizes metal-to-metal programmable antifuse interconnects. The SX-A architecture emphasizes high-speed routing through DirectConnect and FastConnect resources, allowing for predictable timing and high resource utilization.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Cross-referencing with other speed grades or package types within the A54SX16 series requires checking specific electrical parameter compatibility.
