A54SX72A-PQG208

Overview

The A54SX72A-PQG208 is a nonvolatile Field Programmable Gate Array (FPGA) from the Microchip Actel SX-A family, housed in a 208-pin Plastic Quad Flat Pack (PQFP). It provides 108,000 system gates and supports up to 360 user-programmable I/O pins. The device operates on a 0.22 μm / 0.25 μm CMOS antifuse process technology. Standard speed grades include blank (Standard), -1, and -2, with the -3 grade discontinued. The component supports mixed-voltage operation at 2.5 V, 3.3 V, and 5 V, featuring hot-swap compliant I/Os and compliance with IEEE 1149.1 Boundary-Scan Testing.

Feature Summary

• Utilizes metal-to-metal programmable antifuse interconnect elements for permanent low-impedance connections and high performance.
• Features a sea-of-modules architecture with DirectConnect and FastConnect routing resources for deterministic timing and minimal propagation delays.
• Includes four quadrant clocks (QCLK) capable of driving individual chip quadrants or grouped sections for complex clock distribution.
• Supports flexible I/O configurations with individually selectable slew rates, pull-up/pull-down resistors, and hot-swap capabilities.

Applications

• High-performance digital logic integration requiring deterministic timing
• Systems requiring hot-swappable interface capabilities
• Complex state machines and fast counters utilizing local routing resources
• Applications needing secure, nonvolatile single-chip solutions

Procurement Notes

Verify the specific speed grade suffix required for the design, as standard packaging options vary by grade. Confirm that the PQFP package availability aligns with current manufacturing notices, noting that certain speed grades within this family have been discontinued. Ensure the ordering suffix matches the desired temperature range and RoHS compliance status before finalizing procurement.

Selection Notes

Select the A54SX72A when designs require 108,000 system gates and extensive I/O capacity up to 360 pins. Consider the -1 or -2 speed grades if higher performance than standard is needed. Verify that the 208-pin PQFP package fits the PCB layout constraints. Check if quadrant clock resources are necessary for the specific clock network topology required by the application.

Part Context

This component belongs to the Actel SX-A FPGA family, which is characterized by its antifuse-based nonvolatile architecture. The SX-A series offers a range of capacities from 12,000 to 108,000 system gates. The A54SX72A represents the highest capacity device in this specific lineup, providing the maximum number of logic modules and routing resources available in the family.

Replacement Considerations

Public confirmed substitute part numbers are not provided in the source material. Designers should consult official discontinuation notices or contact the manufacturer for recommended alternatives due to the proprietary nature of the antifuse architecture and specific pinout configurations.
