A54SX16-1VQ100I

Overview

The A54SX16-1VQ100I is a Field Programmable Gate Array from the Actel SX-A family, featuring 24,000 typical system gates and 1,452 configurable logic blocks. It operates within a voltage range of 2.25 V to 2.75 V for core supply and supports mixed-voltage I/O standards including 3.3 V and 5 V PCI, TTL, LVTTL, and LVCMOS2. The device utilizes a 0.22 μm / 0.25 μm CMOS antifuse process technology and provides up to 81 user-programmable I/O pins in its 100-pin Thin Quad Flat Pack (TQFP) package. Designed for industrial applications, it functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse interconnect elements for permanent configuration without external memory.
• Hot-swap compliant I/Os allowing safe insertion into electrically active systems with no sequencing required for supply voltages.
• Configurable weak-resistor pull-up or pull-down capabilities for individual I/O pins at power-up to ensure deterministic initialization states.
• Support for IEEE Standard 1149.1 Boundary-Scan Testing via JTAG interface with dedicated or flexible pin modes.

Applications

• Industrial control systems requiring deterministic timing and high reliability
• Mixed-voltage interface designs supporting 3.3 V and 5 V signaling standards
• Applications necessitating hot-swappable hardware integration

Procurement Notes

Verify component authenticity through authorized Microchip Technology distributors. Confirm that the ordering suffix matches the specific speed grade, package type, and industrial temperature range requirements. Ensure compliance with RoHS directives if applicable to the manufacturing environment. Check for any product change notifications regarding lead-free packaging updates before finalizing procurement orders.

Selection Notes

Select this model when 24,000 system gates and 1,452 logic modules are sufficient for the design complexity. The -1 speed grade offers approximately 15% faster performance than standard speed grades. Ensure the TQFP-100 package fits the PCB footprint constraints. Verify that the 2.5 V core voltage requirement aligns with the available power rails in the target system architecture.

Part Context

This component belongs to the Actel SX-A FPGA family, which bridges the gap between CPLDs and larger FPGAs. The SX-A series is characterized by its antifuse technology, providing nonvolatile configuration and enhanced security against reverse engineering compared to SRAM-based devices. It serves as a cost-effective platform for integrating complex logic functions while reducing time-to-market for embedded designs.

Replacement Considerations

Direct replacements include other variants within the A54SX16A series such as A54SX16A-1TQG100I or A54SX16A-2TQG100I, depending on required speed grades and package types. Cross-family migration to newer Microsemi/Actel devices may require significant schematic and software redesign due to architectural differences.
