A54SX32A-1TQG100I

Overview

The A54SX32A-1TQG100I is an industrial-grade FPGA from the Microchip SX-A family, featuring 48,000 system gates and a 100-pin TQFP package. It operates within a voltage range of 2.25 V to 2.75 V and supports up to 81 user I/Os. The device provides 2,880 logic modules, including 1,800 dedicated flip-flops, and three global clock networks. It utilizes antifuse technology for nonvolatile configuration and supports mixed-voltage I/O standards.

Feature Summary

• Supports hot-swap operations and power-up/down without supply sequencing requirements
• Provides deterministic timing with high-drive routing and segmented clock networks
• Includes IEEE 1149.1 compliant boundary-scan testing capabilities
• Features Actel Secure Programming Technology to prevent reverse engineering

Applications

• Industrial control systems requiring robust environmental tolerance
• High-performance digital signal processing applications
• Complex state machine implementations with strict timing constraints

Procurement Notes

Verify the specific ordering suffix 'I' confirms the industrial temperature grade (-40°C to +85°C). Confirm the 'G' suffix indicates RoHS compliance if required by your assembly process. Ensure the TQFP-100 package dimensions match your PCB footprint specifications before finalizing procurement orders.

Selection Notes

Select this component when nonvolatile antifuse technology is preferred over volatile SRAM-based FPGAs. Consider the 48,000 gate capacity and 81 I/O limit for medium-complexity designs. Verify that the 2.5V core voltage aligns with your system's power distribution network and I/O interface requirements.

Part Context

This part belongs to the Microchip (formerly Actel) SX-A family of antifuse FPGAs. The SX-A series is characterized by its metal-to-metal programmable interconnects and high-speed performance. The A54SX32A variant specifically offers 48,000 system gates, positioning it between the smaller A54SX16A and larger A54SX72A devices in terms of logic density.
