A54SX32A-TQG176I

Overview

The A54SX32A-TQG176I is an SX-A series Field Programmable Gate Array (FPGA) manufactured by Microsemi. It provides 48,000 typical system gates and 2,880 configurable logic blocks within a 176-pin Thin Quad Flat Pack (TQFP) package. The device supports up to 147 user-programmable I/O pins and operates at a maximum internal clock frequency of 350 MHz with a system performance of 250 MHz. It utilizes 0.22 μm / 0.25 μm CMOS antifuse technology and supports mixed-voltage operation for 2.5 V, 3.3 V, and 5 V I/Os. The Industrial temperature grade (-40°C to +85°C) ensures reliable operation in demanding environments.

Feature Summary

• Supports hot-swappable I/O configurations allowing safe insertion into active systems without power sequencing requirements.
• Features deterministic timing through patented metal-to-metal antifuse interconnects and dedicated routing resources like DirectConnect.
• Includes IEEE 1149.1 compliant Boundary-Scan Testing capabilities for enhanced diagnostic and verification functions.

Applications

• High-performance digital signal processing requiring low-latency logic execution
• Industrial control systems necessitating wide operating temperature ranges
• Complex state machine implementations utilizing fast local routing resources

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current product documentation to confirm package type and temperature grade compatibility. Ensure that the design environment supports the required antifuse programming tools and that the target application accounts for the nonvolatile nature of the configuration memory.

Selection Notes

Select this component when designs require high-density logic within a surface-mount TQFP form factor. Consider the 147 available user I/Os and the support for mixed-voltage standards when interfacing with diverse peripheral devices. Evaluate the 350 MHz internal performance capability against the specific timing constraints of the intended logic architecture.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which are characterized by their use of antifuse technology for permanent configuration. The SX-A series is designed to replace multiple complex programmable logic devices (CPLDs) or gate arrays in single-chip solutions, offering significant reductions in board space and power consumption while maintaining high-speed performance.

Replacement Considerations

Direct replacements include other speed grades within the A54SX32A series such as A54SX32A-1TQG176I or A54SX32A-2TQG176I for higher performance requirements. Alternative packages for the same logical capacity include the FBGA variants like A54SX32A-FG256I.
