AFS090-2QNG180

Overview

The Microsemi AFS090-2QNG180 is a Fusion mixed-signal FPGA featuring 90,000 system gates and 2,304 tiles. It utilizes an advanced 130-nm flash-based CMOS process with seven metal layers. The device includes 2 Mbits of user flash memory and 1 Kbit of FlashROM. Integrated analog resources comprise a 12-bit ADC supporting up to 600 Ksps and five Analog Quads. It operates from a single 3.3 V supply with an on-chip 1.5 V regulator. The QN180 package provides 60/16 digital I/Os in a Quad Flat No Lead configuration.

Feature Summary

• Instant On nonvolatile flash technology eliminates external boot PROMs and firmware loading delays.
• Integrated mixed-signal architecture combines high-performance logic with analog peripherals on a single chip.
• Advanced security features include FlashLock protection and 128-bit AES decryption for IP safeguarding.
• On-chip voltage regulation and low-power modes support efficient power management applications.

Applications

• Power management systems
• Smart battery charging circuits
• Clock generation and management
• Motor control applications

Procurement Notes

Verify the specific ordering suffix against official Microsemi documentation to confirm temperature grade and packaging compliance. Ensure compatibility with Libero SoC software versions required for the Fusion family. Confirm availability status as production or transferred parts before finalizing procurement plans.

Selection Notes

Select this model for designs requiring integrated analog capabilities alongside programmable logic. The QN180 package suits space-constrained applications needing moderate I/O counts. Consider the 90,000 gate capacity relative to design complexity and verify that the 2 Mbit flash memory meets storage requirements.

Part Context

This component belongs to the Microsemi Fusion family of mixed-signal FPGAs. It shares architectural similarities with other devices like the AFS250 and AFS600 but offers lower logic density. The Fusion series is characterized by its instant-on flash technology and embedded analog peripherals.

Replacement Considerations

Pin-compatible alternatives within the same package include the AFS250 and AFS600 models. Verify functional equivalence regarding gate count and analog resource availability when substituting these higher-density devices.
