A54SX72A-FPQG208

Overview

The A54SX72A-FPQG208 is an SX-A family Field Programmable Gate Array (FPGA) manufactured by Microchip Technology. It features 108,000 system gates and 6,036 logic modules within a 208-pin Plastic Quad Flat Pack (PQFP) package. The device supports mixed-voltage operation at 2.5 V, 3.3 V, and 5 V with 5 V input tolerance. It offers up to 171 user-programmable I/Os, three global clocks, and four quadrant clocks. The component utilizes 0.22 μm / 0.25 μm CMOS antifuse technology for nonvolatile configuration.

Feature Summary

• Nonvolatile single-chip solution using metal-to-metal programmable antifuse interconnect elements
• Supports hot-swap compliant I/Os allowing power-up/down without supply voltage sequencing
• Includes unique in-system diagnostic and verification capability with Silicon Explorer II
• Features Actel Secure Programming Technology with FuseLock to prevent reverse engineering

Applications

• High-performance designs requiring deterministic timing and low power consumption
• Systems needing mixed-voltage I/O standards including 3.3 V/5 V PCI and 5 V TTL
• Applications requiring secure, nonvolatile FPGA implementation without external configuration memory

Procurement Notes

Verify the specific speed grade suffix associated with the FPQG208 designation, as standard speed grades are indicated by a blank space while faster grades use -1 or -2 suffixes. Confirm temperature grade requirements against the available Commercial, Industrial, Automotive, and Military options. Check current availability status as older SX-A family components may have limited stock or end-of-life implications.

Selection Notes

Select this device when 108,000 system gates and 6,036 logic modules are required in a 208-pin PQFP form factor. Ensure design compatibility with 0.22 μm / 0.25 μm CMOS process technology. Verify that the application benefits from the specific clock resources, including four quadrant clocks available only in the A54SX72A variant. Consider the nonvolatile nature of the antifuse architecture for permanent configuration needs.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which are designed for cost-effective, high-performance applications. The SX-A family utilizes antifuse technology, providing a nonvolatile, single-chip solution. The A54SX72A represents the highest capacity device in this specific series, offering significant logic density compared to lower-end models like the A54SX08A or A54SX16A.

Replacement Considerations

Direct replacements within the same package and pinout include other speed grades of the A54SX72A, such as A54SX72A-1PQG208 or A54SX72A-2PQG208, depending on timing requirements. Different temperature grades like A54SX72A-I or A54SX72A-M are available for industrial or military environments. Cross-family migration to newer Microchip FPGA families requires schematic and software redesign.
