A54SX16P-VQG100

Overview

The A54SX16P-VQG100 is an antifuse-based Field Programmable Gate Array from the Actel SX-A family, manufactured by Microchip Technology. It provides 24,000 system gates and 1,452 configurable logic blocks (CLBs). The device supports up to 81 user-programmable I/Os in a 100-pin Thin Quad Flat Pack (TQFP) package. It operates with internal clock frequencies up to 350 MHz and system performance up to 250 MHz. The FPGA utilizes 0.22 μm / 0.25 μm CMOS technology and supports mixed-voltage I/O standards including 2.5 V, 3.3 V, and 5 V.

Feature Summary

• Nonvolatile single-chip solution using metal-to-metal programmable antifuse interconnect elements for permanent configuration without external memory.
• Supports hot-swap capabilities and power-up/down friendly operation, allowing supply voltages to be powered in any order without sequencing requirements.
• Features deterministic timing through dedicated routing resources like DirectConnect and FastConnect, ensuring predictable signal propagation delays.
• Includes Actel Secure Programming Technology with FuseLock to prevent reverse engineering and unauthorized design access.

Applications

• High-performance digital logic integration replacing complex CPLDs or gate arrays.
• Systems requiring deterministic timing and fast state machine execution.
• Applications needing nonvolatile configuration without boot-time bitstream loading.

Procurement Notes

Verify the specific speed grade suffix associated with the P designation in the official datasheet ordering information, as standard commercial grades typically use different suffixes. Confirm that the TQFP-100 package availability aligns with current manufacturing support for the SX-A family. Ensure compliance with RoHS requirements if applicable to the specific revision.

Selection Notes

Select this device when 24,000 system gates and 1,452 CLBs are sufficient for the design complexity. Consider the SX-A family's low capacitance interconnect for high-speed applications requiring sub-nanosecond local routing. Verify that the required I/O voltage levels (2.5V, 3.3V, or 5V) match the available configurable I/O standards supported by the device.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which are characterized by their antifuse technology and high-density logic architecture. The SX-A series offers various gate counts ranging from 12,000 to 108,000 system gates, providing scalable solutions for embedded logic applications. The family is known for its robust security features and deterministic performance characteristics.

Replacement Considerations

Direct replacements within the same package and pinout include other devices from the A54SX16A series with compatible speed grades, such as A54SX16A-TQ100. For higher capacity needs, consider the A54SX32A series, though pin compatibility must be verified against the specific package options listed in the datasheet.
