AFS090-1FGG256I

Overview

The AFS090-1FGG256I is a Fusion mixed-signal FPGA featuring 90,000 system gates and 2,304 tiles. It utilizes a 130-nm flash-based CMOS process with a single 3.3 V supply and an on-chip 1.5 V regulator. The device includes 2 Mbits of user flash memory, 1 Kbit FlashROM, and 27 kbits of SRAM. Integrated analog resources comprise a 12-bit ADC supporting up to 15 input channels and five MOSFET gate driver outputs. Operating in the industrial temperature range (-40°C to +100°C), it offers 350 MHz system performance and supports advanced digital I/O standards.

Feature Summary

• Integrates high-performance reprogrammable flash technology with embedded analog peripherals for mixed-signal applications.
• Provides instant-on functionality without external boot PROMs, utilizing nonvolatile flash configuration.
• Includes integrated analog-to-digital conversion with high-voltage input tolerance and programmable gate drivers.
• Features robust security mechanisms including FlashLock and 128-bit AES encryption for IP protection.

Applications

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

Procurement Notes

Verify the specific ordering suffix 'I' confirms the industrial temperature grade (-40°C to +100°C) as defined in the datasheet. Confirm package type FG256 matches design requirements. Check RoHS compliance status, noting that QN packages are RoHS compliant while standard FG packages may differ. Ensure the 'Y' security license suffix is included if cryptographic IP implementation is required.

Selection Notes

Select this model for designs requiring mixed-signal integration within a compact footprint. The AFS090 provides sufficient logic density for supervisory functions and moderate data processing. Consider the FG256 package constraints regarding available I/O banks. Evaluate the 15-channel ADC limit against sensor interface needs. Compare against higher-density models like AFS250 if additional logic or memory resources are anticipated.

Part Context

This component belongs to the Microsemi Fusion family of mixed-signal FPGAs. It shares architectural similarities with the AFS250, AFS600, and AFS1500 devices but offers lower logic density. The Fusion platform integrates flash memory, analog blocks, and VersaTile logic into a single chip, distinguishing it from traditional SRAM-based FPGAs.

Replacement Considerations

Direct pin-compatible replacements within the same package include other speed grades of the AFS090 (e.g., AFS090-2FGG256). For increased capacity, consider the AFS250 series, though pin compatibility varies by package. Verify software toolchain support in Libero SoC for migration.
