A54SX32A-2FG144I

Overview

The A54SX32A-2FG144I is a Field Programmable Gate Array from the SX-A family, featuring 48,000 system gates and 2,880 logic modules. It operates at a maximum clock frequency of 250 MHz with an internal performance of 350 MHz. The device utilizes 0.22 μm / 0.25 μm CMOS antifuse technology and supports mixed-voltage I/O standards including 2.5 V, 3.3 V, and 5 V. It is housed in a 144-pin Fine Pitch Ball Grid Array (FBGA) package and is rated for industrial temperature operation ranging from -40°C to +85°C.

Feature Summary

• Supports hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements.
• Provides deterministic timing through user-controllable routing resources like DirectConnect and FastConnect.
• Includes boundary-scan testing capabilities compliant with IEEE Standard 1149.1 (JTAG).
• Features Actel Secure Programming Technology with FuseLock to prevent reverse engineering.

Applications

• High-performance digital signal processing requiring fast counters and state machines.
• PCI-compliant interface designs supporting 66 MHz PCI standards.
• Mixed-voltage system integration utilizing 3.3 V, 5 V, and 2.5 V I/O levels.

Procurement Notes

Verify the specific speed grade suffix '2' corresponds to approximately 25% faster performance than standard speed. Confirm the 'I' suffix indicates industrial temperature range (-40 to +85°C). Ensure the FBGA144 package matches the required footprint. Check current availability status as older antifuse devices may have limited production runs.

Selection Notes

Select this model when 48,000 system gates are required with high-speed performance. The -2 speed grade offers faster propagation than standard grades. Choose the FG package for fine-pitch BGA applications. Verify that the 144-pin count provides sufficient I/O for the design, noting it supports up to 111 user I/Os in this package.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which utilize nonvolatile antifuse technology. The SX-A series is designed for low-power, high-performance applications, offering a single-chip solution that integrates CPLD and FPGA features. It is manufactured using 0.22/0.25 micron CMOS process technology.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Consider checking for updated Microchip or Actel FPGA families if long-term supply assurance is required, as antifuse devices may be subject to discontinuation notices.
