A54SX32A-TQ144I

Overview

The A54SX32A-TQ144I is a Field Programmable Gate Array from the SX-A family, manufactured by Microchip Technology. It features 48,000 system gates and 2,880 logic modules within a 144-pin Thin Quad Flat Pack (TQFP) package. The device supports up to 113 user-programmable I/O pins and operates with supply voltages ranging from 2.25 V to 2.75 V. It provides internal performance of 350 MHz and system performance of 250 MHz. The component is rated for industrial temperature grades, functioning reliably between -40°C and +85°C.

Feature Summary

• Supports mixed-voltage operation including 2.5 V, 3.3 V, and 5 V with 5 V input tolerance
• Features hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements
• Includes nonvolatile antifuse technology that prevents reverse engineering and design theft via FuseLock security
• Provides deterministic timing through patented metal-to-metal programmable interconnect elements

Applications

• 66 MHz PCI compliant single-chip solutions
• High-performance state machines and fast counters requiring deterministic timing
• Systems requiring boundary-scan testing in compliance with IEEE Standard 1149.1 (JTAG)

Procurement Notes

Verify the specific ordering suffix 'I' confirms the industrial temperature range (-40°C to +85°C). Confirm the package type corresponds to the 144-pin TQFP form factor. Ensure compatibility with Actel Designer software for programming the nonvolatile antifuse architecture. Check current availability status as legacy FPGA families may have limited production runs.

Selection Notes

Select this model when 48,000 system gates are required within a 144-pin surface-mount footprint. Choose the industrial grade variant for environments exceeding commercial temperature limits. Verify that the 2.5 V core voltage aligns with the target system's power rails. Consider the 113 available I/O count against interface requirements before finalizing the part number.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which utilizes 0.22 μm / 0.25 μm CMOS antifuse technology. The SX-A series is designed for low-power, high-performance applications, offering a cost-effective alternative to multiple CPLDs or gate arrays. The family includes devices ranging from 12,000 to 108,000 system gates.
