A54SX32A-FG256

Overview

The A54SX32A-FG256 is a Field Programmable Gate Array from the Microchip Technology SX-A family, featuring 48,000 system gates and 203 user I/Os. It operates within a supply voltage range of 2.25 V to 2.75 V at a nominal 2.5 V. The device supports a maximum operating frequency of 238 MHz and functions across a commercial temperature range of 0°C to +70°C. It utilizes a 1.0 mm Fine Pitch Ball Grid Array (FBGA) package with 256 pins.

Feature Summary

• Supports hot-swap compliant I/Os for safe insertion into active systems without power sequencing requirements.
• Provides nonvolatile single-chip configuration using antifuse technology to prevent reverse engineering.
• Enables mixed-voltage operation with configurable I/O standards including 3.3V/5V PCI, 5V TTL, and 2.5V LVCMOS2.

Applications

• High-performance logic integration replacing complex CPLDs or gate arrays.
• Systems requiring deterministic timing and pin-locking capabilities.
• Applications needing secure design protection against unauthorized access.

Procurement Notes

Verify component authenticity through authorized Microchip distributors. Confirm RoHS compliance status as packaging suffixes may vary. Check for discontinuation notices or lifecycle changes prior to finalizing procurement plans.

Selection Notes

Select this model when 48,000 system gates and 203 I/Os are required in a 256-pin FBGA package. Ensure the application environment remains within the commercial temperature limits of 0°C to +70°C. Verify that the 2.5V core voltage aligns with the target system power architecture.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which utilize metal-to-metal programmable antifuse interconnect elements. The family offers high performance with internal clock frequencies up to 350 MHz and supports various temperature grades and package options for diverse industrial applications.

Replacement Considerations

Direct replacements include other speed grades within the A54SX32A series such as A54SX32A-1FG256 or A54SX32A-2FG256 if higher performance is needed. For lower performance requirements, standard speed variants may be considered. Package variations like FBGG256A exist but require verification of electrical compatibility.
