A54SX32A-2TQG100I

Overview

The A54SX32A-2TQG100I is a Field Programmable Gate Array from the SX-A family, featuring 48,000 system gates and 2880 logic modules. It operates with an internal performance of 350 MHz and supports up to 81 user-programmable I/Os in a 100-pin Thin Quad Flat Pack (TQFP) package. The device utilizes 0.22 μm / 0.25 μm CMOS antifuse technology and supports mixed-voltage operation at 2.5 V, 3.3 V, and 5.0 V with 5.0 V input tolerance. It includes three global clock networks and complies with IEEE Standard 1149.1 for boundary-scan testing.

Feature Summary

• Supports hot-swappable I/O configurations and power-up/down friendly operation without supply voltage sequencing requirements.
• Provides deterministic timing through unique local routing resources including DirectConnect and FastConnect for predictable signal propagation.
• Integrates Actel Secure Programming Technology with FuseLock to prevent reverse engineering and design theft.
• Enables 100% resource utilization and 100% pin locking for concurrent printed circuit board development.

Applications

• 66 MHz PCI compliant designs
• Low-power high-performance embedded systems
• Industrial control applications requiring mixed-voltage I/O

Procurement Notes

Verify the specific speed grade suffix '2' indicates approximately 25% faster performance than standard speed. Confirm the 'I' suffix denotes industrial temperature range operation from -40°C to +85°C. Ensure the TQFP package type matches the target PCB footprint. Check for RoHS compliance status as packaging options may vary.

Selection Notes

Select this model when 48,000 system gates are required within a compact 100-pin surface-mount package. Consider the SX-A architecture for applications needing deterministic timing and nonvolatile single-chip solutions. Evaluate the 2.5 V, 3.3 V, and 5.0 V mixed-voltage capabilities if interfacing with diverse peripheral voltages is necessary.

Part Context

This component belongs to the Microchip (formerly Actel) SX-A FPGA family, which uses antifuse technology for permanent configuration. The A54SX32A variant offers a mid-range capacity within the series, bridging the gap between smaller devices like the A54SX16A and larger ones like the A54SX72A. It is designed for cost-effective integration of CPLD and FPGA functionalities.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing Actel Designer software versions for programming and place-and-route tools.
