AFS1500-2FGG256I

Overview

The AFS1500-2FGG256I 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 an industrial temperature range from -40°C to +85°C and utilizes a 256-pin FBGA package with a 1 mm pitch.

Feature Summary

• Integrates high-performance reprogrammable flash technology for nonvolatile configuration retention without external memory.
• Supports live at power-up functionality to enable immediate system operation upon power application.
• Provides embedded user flash memory with configurable datapath widths for data storage applications.

Applications

• Industrial control systems requiring secure, low-power programmable logic.
• Automotive electronics demanding high reliability and nonvolatile configuration.
• Aerospace and defense platforms utilizing radiation-tolerant or high-reliability components.

Procurement Notes

Verify the specific suffix '2' indicates the industrial temperature grade (-40°C to +85°C) and 'I' denotes the lead-free/rohs compliant variant if applicable per the latest datasheet revision. Confirm package dimensions against the 256-FPBGA specification. Ensure compatibility with existing board layouts regarding the 1 mm ball pitch and thermal requirements for the FBGA form factor during integration.

Selection Notes

Select this component when a mid-density FPGA solution with integrated nonvolatile flash is required to reduce bill-of-materials complexity. Compare gate counts against the 600,000-gate AFS600 model if lower resource usage suffices. Evaluate the 1.5V core voltage requirements against available power rails in the target design to ensure proper regulation and stability.

Part Context

This part belongs to the Actel Fusion family, which combines SRAM-based FPGA fabric with embedded Flash memory. The series bridges the gap between volatile SRAM FPGAs and traditional anti-fuse devices by offering reprogrammability with instant-on capabilities. The 1.5M gate count positions it as a versatile solution for complex digital logic in compact packages.

Replacement Considerations

Direct pin-compatible replacements within the same package may include other variants in the AFS1500 series with different speed grades or temperature ranges, such as the commercial grade version. Verify that any substitute maintains the 256-ball FBGA footprint and 1.5V operating voltage specifications.
