A54SX16A-TQ100

Overview

The A54SX16A-TQ100 is a Field Programmable Gate Array from the Actel SX-A family, featuring 24,000 system gates and 1,452 logic modules. It operates with a standard speed grade in a 100-pin Thin Quad Flat Pack (TQFP) package. The device supports up to 81 user-programmable I/O pins and utilizes 0.22 μm / 0.25 μm CMOS antifuse technology. It functions within a supply voltage range of 2.25 V to 2.75 V, typically at 2.5 V. The component achieves 250 MHz system performance and 350 MHz internal performance.

Feature Summary

• Nonvolatile single-chip solution using metal-to-metal programmable antifuse interconnect elements for permanent low-impedance connections.
• Hot-swap compliant I/Os allowing insertion into active systems without degrading host reliability or requiring specific power sequencing.
• Configurable I/O support for mixed-voltage operation including 3.3 V/5 V PCI, 5 V TTL, 3.3 V LVTTL, and 2.5 V LVCMOS2 standards.
• Actel FuseLock™ security technology prevents reverse engineering and design theft by hiding special security fuses throughout the fabric.

Applications

• High-performance digital logic integration replacing complex CPLDs or gate arrays
• PCI-compliant interface designs supporting 66 MHz operations
• Systems requiring deterministic timing and user-controllable signal propagation delays

Procurement Notes

Verify the specific ordering suffix for temperature grade and packaging compliance. The base model designation does not explicitly state the temperature range in the provided text; commercial grade is implied by the blank application code, but industrial or military variants exist. Confirm RoHS status via the 'G' suffix if required. Check current manufacturing status as older speed grades may be discontinued.

Selection Notes

Select this device for applications requiring 24,000 system gates and 100-pin surface mount packaging. Ensure the design fits within the 81 available user I/O constraints. Verify that the standard speed grade meets the 250 MHz system performance requirement. Consider the TQFP package dimensions and thermal characteristics for PCB layout planning.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which are fabricated on high-voltage twin-well CMOS process technology. The family includes devices ranging from 12,000 to 108,000 system gates. The A54SX16A variant specifically offers a balance of logic density and I/O count suitable for mid-range programmable logic applications.

Replacement Considerations

Direct replacements depend on the required temperature grade and speed. Variants such as A54SX16A-I or A54SX16A-M offer different operating ranges. Note that higher speed grades like -1 or -2 provide faster performance but may have different timing characteristics. Lower speed grade -F is also available.
