A54SX72A-1FG256I

Overview

The A54SX72A-1FG256I is a nonvolatile Field Programmable Gate Array (FPGA) from the SX-A family, manufactured by Microchip Technology. It features 108,000 system gates and 6,036 configurable logic blocks (CLBs). The device supports up to 203 user-programmable I/Os and operates within a supply voltage range of 2.25V to 5.25V. It utilizes 0.22 μm / 0.25 μm CMOS antifuse technology for permanent configuration. The component is housed in a 256-pin Fine Pitch Ball Grid Array (FBGA) package with a 1.0 mm pitch. It is rated for industrial temperature operation between -40°C and +85°C.

Feature Summary

• Supports mixed-voltage I/O standards including 3.3V/5V PCI, 5V TTL, 3.3V LVTTL, and 2.5V LVCMOS2.
• Features hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements.
• Includes dedicated quadrant clock networks for efficient global clock distribution across the die.
• Provides boundary-scan testing capabilities compliant with IEEE Standard 1149.1 (JTAG).

Applications

• High-performance digital logic integration requiring deterministic timing.
• Systems requiring secure, nonvolatile single-chip solutions with reverse-engineering protection.
• 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 manufacturer's datasheet. Confirm the package type matches the required 256-pin FBGA footprint. Ensure design compatibility with the SX-A family architecture before procurement.

Selection Notes

Select this model for designs requiring approximately 108,000 system gates and extensive I/O connectivity. Consider the speed grade '-1' for performance requirements exceeding standard specifications. Verify that the application does not require embedded memory or processor cores, as this device is a pure FPGA fabric.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which are characterized by their metal-to-metal programmable antifuse interconnect technology. The family offers high-density logic resources with low power consumption and inherent security against reverse engineering due to the nonvolatile nature of the antifuse structure.

Replacement Considerations

Direct replacements within the same package and pinout include other speed grades of the A54SX72A series, such as A54SX72A-FGG256I or A54SX72A-2FG256I, provided the timing requirements align with the new speed grade specifications.
