A54SX16A-2TQG144

Overview

The A54SX16A-2TQG144 is a Field Programmable Gate Array from the Actel SX-A family, fabricated using 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 24,000 system gates and 1,452 logic modules within a 144-pin Thin Quad Flat Pack (TQFP) package. The device supports up to 113 user-programmable I/O pins and features a maximum clock frequency of 313 MHz. It operates with supply voltages of 2.5 V, 3.3 V, or 5 V, supporting mixed-voltage operation with 5 V input tolerance.

Feature Summary

• Supports hot-swap compliant I/Os allowing insertion into active systems without damage
• Features power-up/down friendly design requiring no sequencing for supply voltages
• Includes nonvolatile single-chip solution preventing configuration bitstream interception
• Provides deterministic, user-controllable timing with up to 100% resource utilization

Applications

• High-performance digital signal processing
• PCI bus interface designs
• State machine implementations
• Data path logic integration

Procurement Notes

Verify the specific speed grade suffix '2' corresponds to the required performance level, as it indicates approximately 25% faster operation than standard speed. Confirm the temperature grade suffix matches the operational environment requirements. Ensure the TQG144 package designation aligns with the PCB footprint specifications. Check for RoHS compliance status if environmental regulations apply to the manufacturing process.

Selection Notes

Select this component when a high-density FPGA with nonvolatile antifuse technology is required. The -2 speed grade offers higher performance suitable for complex logic functions. Consider the mixed-voltage I/O capabilities if interfacing with 5 V legacy devices. Verify that the 144-pin TQFP package fits the available board space and thermal constraints.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which utilizes metal-to-metal programmable antifuse interconnect elements. The family includes devices ranging from 8,000 to 108,000 system gates. The A54SX16A variant specifically targets applications needing moderate density with high-speed performance and robust security features against reverse engineering.
