A54SX16P-VQ100M

Overview

The A54SX16P-VQ100M 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 16,000 typical system gates and 1452 logic modules, including 924 combinatorial cells and 512 dedicated flip-flops. The device supports up to 81 user-programmable I/Os in a 100-pin Thin Quad Flat Pack (TQFP) package with a height of 1.4 mm. It operates at a maximum system frequency of 250 MHz with internal performance reaching 350 MHz. The component supports mixed-voltage operation at 2.5 V, 3.3 V, and 5.0 V with 5.0 V input tolerance.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse interconnect elements for permanent low-impedance connections.
• Hot-swap compliant I/Os allowing insertion into active systems without power sequencing requirements or system degradation.
• Deterministic timing architecture featuring DirectConnect and FastConnect routing resources for predictable signal propagation.
• Integrated Boundary-Scan Testing (BST) compliant with IEEE Standard 1149.1 (JTAG) for in-system diagnostic verification.

Applications

• High-performance digital logic integration requiring deterministic timing and pin-locking capabilities
• Systems requiring hot-swappable interface components with mixed-voltage I/O standards
• Secure embedded designs utilizing nonvolatile antifuse technology to prevent reverse engineering

Procurement Notes

Verify the specific ordering suffix 'M' against official Microchip documentation to confirm military temperature grade (-55°C to +125°C). Confirm RoHS compliance status as standard packaging may differ from lead-free variants. Check current product lifecycle status, as older FPGA families often face discontinuation. Ensure design tools support the specific speed grade associated with this part number.

Selection Notes

Select this device when 16,000 system gates and 81 I/Os are sufficient for the target application. Consider the TQFP-100 package constraints regarding pin count and thermal dissipation. Evaluate the need for military-grade temperature range versus commercial options. Verify that the required I/O voltage standards (3.3V/5V PCI, TTL, LVTTL) align with the SX-A family's configurable I/O capabilities.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which utilizes antifuse technology for nonvolatile configuration. The SX-A series is designed for cost-effective, low-power applications requiring high performance. The A54SX16A variant represents the mid-range capacity within the family, offering a balance between logic density and I/O availability compared to the smaller A54SX08A and larger A54SX32A devices.

Replacement Considerations

Direct replacements must match the 100-pin TQFP package and 16,000 gate capacity. Verify compatibility with existing PCB footprints and pin assignments. Consider alternative speed grades within the A54SX16A series if timing requirements differ. Note that newer FPGA architectures may require significant redesign due to differences in configuration methods and I/O standards.
