A54SX32A-1FG256I

Overview

The A54SX32A-1FG256I is an industrial-grade Field Programmable Gate Array from the Microchip SX-A family, featuring 48,000 system gates and a 256-pin Fine Pitch Ball Grid Array (FBGA) package. It supports up to 203 user-programmable I/Os and includes three global clock networks. The device operates within an extended temperature range of -40°C to +85°C and utilizes 0.22 μm / 0.25 μm CMOS antifuse technology for nonvolatile configuration.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse interconnect elements
• Supports hot-swap compliant I/Os with configurable weak-resistor pull-up or pull-down at power-up
• Includes dedicated boundary-scan testing capabilities compliant with IEEE Standard 1149.1 (JTAG)
• Features deterministic timing through segmented routing and high-drive clock networks

Applications

• Industrial control systems requiring robust performance in harsh environments
• High-speed data path logic and fast counters utilizing DirectConnect resources
• Secure embedded designs protected by Actel Secure Programming Technology

Procurement Notes

Verify component authenticity through authorized Microchip distributors. Confirm that the ordering suffix 'I' corresponds to the specified industrial temperature grade (-40°C to +85°C). Ensure compatibility with existing PCB footprints for the 256-pin FBGA package before finalizing procurement orders.

Selection Notes

Select this model when industrial temperature stability is required alongside high-density logic implementation. The -1 speed grade offers approximately 15% faster performance than standard variants. Verify that the 256-pin FBGA package meets board space constraints and thermal dissipation requirements for the target application environment.

Part Context

This part belongs to the SX-A FPGA family, which provides a cost-effective platform for integrating complex logic functions. The A54SX32A variant specifically offers 48,000 system gates, bridging the gap between lower-capacity devices like the A54SX16A and higher-capacity models such as the A54SX72A.

Replacement Considerations

Direct pin-compatible replacements within the same package are limited due to the discontinuation of certain speed grades. Evaluate the A54SX32A-FG256I for commercial grade applications if temperature ranges allow, or consider the A54SX32A-1FG256M for military specifications.
