AFS1500-2FG256

Overview

The AFS1500-2FG256 is a Fusion FPGA from Microchip Technology, featuring 1.5 million system gates and packaged in a 256-LBGA (17x17 mm) footprint. It operates on a supply voltage range of 1.425V to 1.575V with an industrial temperature rating of -40°C to +85°C. The device provides 119 I/O pins and includes 276,480 bits of embedded RAM. It utilizes a non-volatile Flash-based CMOS process that supports Live at Power-Up functionality.

Feature Summary

• Non-volatile Flash-based architecture retains configuration data when powered off without external memory requirements.
• Supports Live at Power-Up (LAPU) for immediate system operation upon power application.
• Integrates on-chip regulators allowing single 3.3V supply input while internally managing core voltages.

Applications

• Industrial control systems requiring non-volatile reprogrammability
• Secure embedded applications utilizing FlashLock security features
• Mixed-signal designs leveraging integrated analog capabilities

Procurement Notes

Verify the specific suffix '2' corresponds to the required industrial temperature grade (-40°C to +85°C). Confirm package dimensions match the 256-LBGA specification. Check RoHS status as some legacy Fusion devices may not be compliant. Ensure ESD handling procedures are followed during installation.

Selection Notes

Select this model for designs needing high gate density with instant-on capabilities. Compare against M1AFS variants if ARM Cortex-M1 integration is required. Verify I/O count sufficiency for the target interface requirements. Consider thermal management solutions suitable for the FBGA package type.

Part Context

This component belongs to the Microchip Fusion family, bridging the gap between traditional SRAM FPGAs and ASICs. It combines the flexibility of programmable logic with the non-volatility of Flash technology. The series is designed for cost-sensitive applications requiring low power consumption and high reliability.

Replacement Considerations

Direct substitutes include other AFS1500 variants with different packages or speed grades. Cross-reference with U1AFS1500-FG256 for pin-compatible options within the same gate count family. Verify electrical characteristics match before swapping components.
