A54SX32A-FGG256I

Overview

The A54SX32A-FGG256I is an industrial-grade Field Programmable Gate Array from the SX-A family, featuring 48,000 system gates and 2,880 logic modules. It utilizes a 0.22 μm/0.25 μm CMOS antifuse technology with a 1.0 mm pitch Fine Pitch Ball Grid Array (FBGA) package containing 256 pins. The device supports up to 203 user-programmable I/Os and operates within an industrial temperature range of -40°C to +85°C. Standard speed grade performance includes 250 MHz system performance and 350 MHz internal clock frequencies.

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 power-up/down without voltage sequencing requirements.
• Includes dedicated boundary-scan testing capabilities compliant with IEEE Standard 1149.1 (JTAG).
• Features individually selectable output slew rates and configurable weak-resistor pull-ups or pull-downs for I/O at power-up.

Applications

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

Procurement Notes

Verify the specific ordering suffix 'I' confirms the industrial temperature grade (-40°C to +85°C) as defined in the official Actel SX-A datasheet. Confirm that the FBGA-256 package type matches the required footprint. Ensure compliance with RoHS standards if applicable to the manufacturing batch. Cross-reference the part number against current Microchip Technology product discontinuation notices.

Selection Notes

Select this component when 48,000 system gates and 203 available I/Os are required for complex logic designs. The industrial temperature rating makes it suitable for environments exceeding commercial limits. Consider the standard speed grade if 250 MHz system performance meets design constraints. Verify that the 256-pin FBGA package fits the target PCB layout constraints.

Part Context

This device belongs to the Actel SX-A FPGA family, which offers high-density logic resources on a single chip. The A54SX32A variant specifically provides 48,000 system gates, positioning it between the lower-capacity A54SX16A and the higher-capacity A54SX72A. The SX-A architecture is known for its sea-of-modules organization and patented antifuse interconnect technology.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult Microchip Technology for current equivalent offerings or alternative packages within the same SX-A family, such as the A54SX32A-FG256I, noting potential differences in package pitch or availability.
