A54SX32A-2FG256I

Overview

The A54SX32A-2FG256I is an antifuse-based Field Programmable Gate Array from the SX-A family, manufactured by Microchip Technology. It provides 48,000 system gates and 2,012 dedicated flip-flops within a 256-pin Fine Pitch Ball Grid Array (FBGA) package. The device operates at a maximum system frequency of 250 MHz with internal performance up to 350 MHz. It supports mixed-voltage I/O standards including 2.5 V, 3.3 V, and 5 V, with 203 user-programmable I/Os. The industrial temperature grade (-40°C to +85°C) ensures reliable operation in demanding environments.

Feature Summary

• Nonvolatile antifuse architecture providing permanent configuration without external memory
• Hot-swap compliant I/Os allowing insertion into active systems without damage
• Deterministic timing through metal-to-metal programmable interconnect elements
• Integrated boundary-scan testing compliant with IEEE Standard 1149.1

Applications

• High-performance digital signal processing requiring deterministic latency
• Industrial control systems operating in extended temperature ranges
• Secure hardware implementations utilizing FuseLock technology
• PCI-compliant interface designs supporting 66 MHz operations

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type, speed grade, and temperature range. Confirm RoHS compliance status as manufacturing changes may affect environmental declarations. Check for any Product Change Notifications regarding packaging or material substitutions prior to finalizing procurement orders.

Selection Notes

Select this component when nonvolatile configuration and high-speed deterministic logic are required. Ensure the design utilizes the available 203 user I/Os effectively within the 256-pin FBGA footprint. Consider the 2.5V core voltage requirement and verify that the power supply sequencing accommodates the hot-swap capabilities of the I/O banks.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which utilizes 0.22/0.25 micron CMOS antifuse technology. The SX-A series is designed for cost-effective, low-power applications requiring high performance. The A54SX32A variant specifically offers 48,000 system gates, positioning it between the smaller A54SX16A and larger A54SX72A devices in terms of capacity.

Replacement Considerations

Direct pin-compatible replacements within the same package and speed grade should be sought from the A54SX32A product line. Verify if higher speed grades (e.g., -1) or different temperature grades (e.g., Commercial C or Military M) are acceptable substitutes based on system requirements.
