AFS1500-1FGG256I

Overview

The AFS1500-1FGG256I is a Fusion series Field Programmable Gate Array (FPGA) manufactured by Microchip Technology. It features 1,500,000 system gates and 38,400 configurable logic blocks (CLBs). The device operates within a supply voltage range of 1.425V to 1.575V and supports an industrial temperature range of -40°C to +85°C. It is housed in a 256-pin FBGA package with a 1mm pitch. Key specifications include 119 I/Os and non-volatile flash-based technology that enables live-at-power-up functionality without external configuration memory.

Feature Summary

• Non-volatile Flash-based architecture retains program data when powered off, eliminating the need for external configuration devices.
• Supports Live at Power-Up (LAPU) for immediate system operation upon power application.
• Integrates on-chip regulators allowing single 3.3V supply operation while internally managing 1.5V core voltage.
• Includes embedded user flash memory with configurable datapath widths for data storage and retrieval.

Applications

• Industrial control systems requiring non-vatile programmability
• Secure embedded applications utilizing FlashLock security features
• Mixed-signal signal processing using integrated analog blocks

Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature grade (-40°C to +85°C). Confirm the package designation matches the 256-pin FBGA form factor. Check for RoHS compliance status as older Actel-branded stock may differ from current Microchip specifications. Ensure the ordering part number aligns with the latest datasheet revisions to avoid pinout or feature discrepancies.

Selection Notes

Select this component for designs requiring high gate density with built-in non-volatility. Compare against the M1AFS1500 series if higher performance or different I/O counts are needed. Consider the U1AFS1500 series for advanced mixed-signal capabilities. Verify that the 1.5V core voltage requirements match the system power budget and that the 256-pin footprint fits the PCB layout constraints.

Part Context

This part belongs to the Fusion family, originally developed by Actel before its acquisition by Microsemi and subsequently Microchip. It bridges the gap between low-density ProASIC devices and high-end SmartFusion SoCs. The AFS1500 variant provides significant logic resources compared to the AFS600, targeting complex digital logic applications in aerospace and defense sectors.

Replacement Considerations

Direct substitutes include the M1AFS1500-1FG256 for updated manufacturing sources. The AFS1500-1FG256YES is a legacy equivalent with similar electrical characteristics but potentially different packaging or compliance status. Cross-reference pinouts carefully when migrating between Actel and Microchip branded versions.
