A54SX08A-TQ144I

Overview

The A54SX08A-TQ144I 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 12,000 system gates and 768 logic modules. The device supports up to 113 user-programmable I/O pins within a 144-pin Thin Quad Flat Pack (TQFP) package. It operates with mixed-voltage support for 2.5 V, 3.3 V, and 5 V supplies, featuring 5 V input tolerance. The architecture delivers 250 MHz system performance and 350 MHz internal clock frequencies.

Feature Summary

• Supports hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements.
• Features deterministic, user-controllable timing with 100% resource utilization and pin locking capabilities.
• Includes nonvolatile single-chip solution with FuseLock security technology to prevent reverse engineering.
• Provides boundary-scan testing compliance with IEEE Standard 1149.1 (JTAG) for diagnostic verification.

Applications

• Low-power, high-performance designs requiring single-chip integration
• Systems requiring hot-swappable interface capabilities
• Applications needing secure programming and anti-tamper protection

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm temperature grade and packaging details. Confirm availability status as legacy antifuse products may have limited supply chains or end-of-life notifications. Ensure design files are compatible with the required Actel Designer software version for the SX-A family.

Selection Notes

Select this component when a nonvolatile FPGA with deterministic timing and high-speed I/O is required. The SX-A architecture is suitable for replacing complex CPLDs or gate arrays in cost-sensitive applications. Consider the 144-pin TQFP package constraints and verify that the 113 available I/Os meet the system interface requirements.
