A54SX16P-TQ144

Overview

The A54SX16P-TQ144 is a Field Programmable Gate Array from the Actel SX-A family, fabricated using 0.22 μm / 0.25 μm CMOS antifuse technology. It contains 1,452 logic modules and provides 24,000 system gates with up to 113 user-programmable I/O pins in a 144-pin Thin Quad Flat Pack (TQFP) package. The device supports mixed-voltage operation at 2.5 V, 3.3 V, and 5 V, featuring hot-swap compliant I/Os and nonvolatile configuration. It achieves 250 MHz system performance and 350 MHz internal clock frequencies.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse interconnect elements for permanent low-impedance connections.
• Supports mixed-voltage I/O standards including 3.3 V/5 V PCI, 5 V TTL, 3.3 V LVTTL, and 2.5 V LVCMOS2 with individual slew rate control.
• Hot-swap compliant architecture allowing power-up/down without voltage sequencing requirements or damage to the host system.
• Includes dedicated boundary-scan testing capabilities compliant with IEEE Standard 1149.1 (JTAG) for diagnostic verification.

Applications

• High-performance digital logic integration requiring deterministic timing and pin-locking
• PCI-compliant interface designs operating at 66 MHz
• Systems requiring secure programming and reverse-engineering protection via FuseLock technology

Procurement Notes

Verify the specific speed grade suffix associated with the part number, as standard commercial grades are indicated by a blank suffix while faster variants use numerical designators. Confirm that the TQFP package type matches the required footprint dimensions. Ensure the temperature range corresponds to the application environment, noting that the 'P' designation typically implies commercial specifications.

Selection Notes

Select this component when a nonvolatile FPGA with high-speed antifuse technology is required. The SX-A architecture offers 100% resource utilization and pin locking, which facilitates concurrent PCB development. Consider the available global and quadrant clock resources if complex timing synchronization is needed within the design constraints of the 144-pin form factor.

Part Context

This device belongs to the Actel SX-A family of FPGAs, which are designed for cost-effective, low-power applications. The family utilizes a sea-of-modules architecture with register cells and combinatorial cells arranged into clusters. The A54SX16 variant specifically targets designs needing approximately 24,000 system gates, bridging the gap between smaller CPLDs and larger gate arrays.
