A54SX32A-1FGG484I

Overview

The A54SX32A-1FGG484I is a Field Programmable Gate Array from the SX-A family, manufactured by Microsemi. It features 48,000 system gates and 2,880 logic modules within a 484-pin Fine Pitch Ball Grid Array package. The device supports up to 249 user-programmable I/O pins and operates at an industrial temperature range of -40°C to +85°C. Utilizing 0.22 μm / 0.25 μm CMOS antifuse technology, it delivers internal performance up to 350 MHz and system performance up to 250 MHz.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse interconnect elements for permanent low-impedance connections.
• Supports hot-swap compliant I/Os allowing safe insertion into electrically active systems without power sequencing requirements.
• Includes dedicated boundary-scan testing capabilities compliant with IEEE Standard 1149.1 (JTAG) for diagnostic verification.
• Features individually configurable weak-resistor pull-up or pull-down states for I/O pins during power-up.

Applications

• High-performance digital logic integration requiring deterministic timing
• Systems requiring nonvolatile configuration without external bitstream memory
• Industrial control applications operating in extended temperature environments

Procurement Notes

Verify the specific ordering suffix 'I' confirms the Industrial temperature grade (-40°C to +85°C). Confirm the '1' speed grade designation against current availability as older grades may be discontinued. Ensure the 484-pin FBGA footprint matches the target PCB design constraints.

Selection Notes

Select this component when 48,000 system gates are required alongside high-speed internal clocking capabilities. Consider the SX-A architecture's unique DirectConnect and FastConnect routing resources for optimized register/logic mix. Verify that the 249 available I/O pins meet the interface requirements for the target application.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which utilizes antifuse technology rather than volatile SRAM configurations. The SX-A series provides a cost-effective platform for integrating CPLD and gate array functionalities into a single chip, emphasizing low power consumption and high reliability.
