AFS1500-FG256I

Overview

The AFS1500-FG256I is a Fusion FPGA from Microchip Technology, featuring 1.5 million system gates and 38,400 configurable logic blocks (CLBs). It operates within a supply voltage range of 1.42 V to 1.58 V, with a nominal rating of 1.5 V. The device supports up to 119 I/Os and includes 276,480 bits of embedded RAM. Packaged in a 256-pin FBGA with a 1 mm pitch, it functions reliably between -40°C and +85°C.

Feature Summary

• High-density programmable logic architecture utilizing advanced flash-based CMOS technology for nonvolatile configuration retention.
• Integrated on-chip voltage regulation enabling single-supply operation while maintaining low power consumption through sleep and standby modes.
• Supports live at power-up functionality allowing immediate system operation without external configuration memory requirements.

Applications

• Industrial automation control systems requiring reprogrammable logic
• Telecommunications infrastructure signal processing
• Automotive electronics interfaces and gateways

Procurement Notes

Verify export compliance documentation prior to purchase, as this component may require additional files for shipment from the United States. Confirm RoHS status and moisture sensitivity level (MSL 3) against specific project environmental requirements. Ensure ordering suffixes match exact package and temperature grade specifications to avoid functional mismatches.

Selection Notes

Select this model when high gate density and flash-based nonvolatility are required without external configuration devices. Compare against the U1AFS1500 series for updated feature sets or the M7AFS600 if ARM core integration is needed. Verify that the 256-pin FBGA footprint aligns with existing PCB layout constraints and thermal management capabilities.

Part Context

This part belongs to the Microchip Fusion FPGA family, which combines high-performance logic with embedded memory and optional processor cores. It succeeds earlier Actel ProASIC technologies, offering improved density and lower power consumption. The FG256 suffix denotes the industrial temperature grade and 256-ball FBGA package type.

Replacement Considerations

The U1AFS1500-FG256I serves as a direct successor within the same package and pinout. For legacy compatibility, verify electrical parameters against older Actel-branded parts. No other cross-family substitutes share identical pin configurations.
