A54SX32A-2TQ144I

Overview

The A54SX32A-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 (CLBs). The device supports up to 113 user-programmable I/O pins in a TQFP-144 package. It operates at a maximum frequency of 313 MHz with an internal performance of 350 MHz. The supply voltage range is 2.25 V to 2.75 V, with a nominal operating voltage of 2.5 V. The industrial temperature grade (-40°C to +85°C) is indicated by the 'I' suffix.

Feature Summary

• Supports hot-swap compliant I/Os for safe insertion into active systems without power sequencing requirements.
• Provides deterministic timing through unique local routing resources like DirectConnect and FastConnect.
• Includes boundary-scan testing capabilities compliant with IEEE Standard 1149.1 (JTAG) for diagnostic verification.

Applications

• High-performance digital signal processing requiring low latency
• Industrial control systems needing deterministic timing and robust I/O
• Prototyping complex logic designs using antifuse technology

Procurement Notes

Verify the specific speed grade and package availability directly with authorized distributors or the manufacturer. Confirm that the industrial temperature rating matches the application environment requirements. Check for any end-of-life notifications or production change notices associated with this part number before finalizing procurement plans.

Selection Notes

Select this component when a nonvolatile FPGA solution with high-speed performance is required. Ensure the design fits within the 48,000 gate capacity and utilizes the available 113 I/Os efficiently. Consider the 2.5V core voltage requirement and verify compatibility with the target I/O standards such as LVCMOS or LVTTL.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which utilize antifuse technology for permanent configuration. The SX-A series is known for its high performance and security features, making it suitable for applications where reverse engineering protection is critical. The A54SX32A variant offers a balance of logic density and I/O count.

Replacement Considerations

Direct replacements may include other speed grades within the A54SX32A series, such as A54SX32A-1TQ144I or A54SX32A-TQ144I, provided the timing requirements are met. Verify pinout compatibility and electrical specifications before substituting.
