AFS090-QNG108I

Overview

The AFS090-QNG108I is a Fusion mixed-signal FPGA featuring 90,000 system gates and 2,304 tiles. It operates on a single 3.3 V supply with an internal 1.5 V regulator. The device includes 2 Mbits of user flash memory, 1 Kbit of FlashROM, and 27 kbits of SRAM. It integrates a 12-bit ADC with up to 600 Ksps sampling rate and 30 scalable analog input channels. The QN108 package provides 37 digital I/Os and 9 analog I/Os. It supports industrial temperature range (-40°C to +100°C) and features 1 PLL.

Feature Summary

• Integrates high-performance flash-based FPGA fabric with embedded analog peripherals for mixed-signal applications.
• Provides Instant On capability without external configuration boot PROMs, ensuring immediate operation upon power-up.
• Includes robust security features such as FlashLock and 128-bit AES encryption for IP protection and secure in-system programming.

Applications

• Power management systems
• Smart battery charging controllers
• Motor control applications

Procurement Notes

Verify the specific ordering suffixes against the manufacturer's current datasheet to confirm package type, speed grade, and temperature range compatibility. Ensure that any required intellectual property licenses, such as those based on the Cryptography Research Inc. patent portfolio, are properly accounted for during procurement planning.

Selection Notes

Select this component when a single-chip solution combining programmable logic, nonvolatile memory, and analog signal processing is required. Consider the AFS090-QNG108I for designs needing industrial temperature stability and integrated MOSFET gate driving capabilities within a compact QN108 footprint.

Part Context

This part belongs to the Microsemi Fusion family of mixed-signal FPGAs, which combines flash technology with analog peripherals. The AFS090 variant represents the entry-level density in this series, offering 90,000 system gates. It shares architectural similarities with higher-density models like the AFS250 and AFS600 but is optimized for cost-sensitive mixed-signal designs.

Replacement Considerations

Direct pin-compatible replacements within the same package may include other AFS090 variants with different speed grades or temperature ratings. For higher performance needs, consider upgrading to the AFS250 series, though package and pin count differences must be evaluated.
