A54SX32-2TQ144I

Overview

The A54SX32-2TQ144I 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 an internal performance of 350 MHz with a system performance of 250 MHz. It operates at supply voltages ranging from 2.25 V to 5.25 V and is rated for industrial temperature grades spanning -40°C to +85°C.

Feature Summary

• Supports mixed-voltage I/O standards 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 boundary-scan testing capabilities compliant with IEEE Standard 1149.1 (JTAG)
• Utilizes nonvolatile antifuse technology that prevents reverse engineering and design theft

Applications

• PCI-compliant single-chip integration solutions
• High-performance digital signal processing designs
• Industrial control systems requiring deterministic timing

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type, speed grade, and temperature range. Confirm RoHS compliance status as packaging options vary. Check current product lifecycle status to ensure availability for new designs.

Selection Notes

Select this component when a nonvolatile FPGA solution with high-speed performance and robust security features is required. Ensure the design utilizes the available 249 user I/Os and verify that the 144-pin TQFP package fits the PCB layout constraints. Consider the 250 MHz system performance limit for timing closure.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which are built on 0.22 μm / 0.25 μm CMOS antifuse technology. The family offers various gate counts and packages, with the A54SX32 variant providing a balance of logic density and pin count for mid-range applications.

Replacement Considerations

Consult the official Microchip SX-A datasheet for direct pin-compatible alternatives within the same family. Verify if other speed grades or package options in the A54SX32 series meet the specific timing and form-factor requirements.
