AFS600-1FG484

Overview

The AFS600-1FG484 is a Field Programmable Gate Array from the Microsemi Fusion family, manufactured using an advanced 130-nm, 7-layer metal, flash-based CMOS process. It provides 600,000 equivalent system gates and 13,824 configurable logic blocks within a 484-pin Plastic Ball Grid Array (PBGA) package with a 1.0 mm pitch. The device operates on a single 3.3 V supply with an integrated 1.5 V regulator, supporting mixed-voltage I/O standards including LVTTL, LVCMOS, LVDS, and LVPECL. It achieves a maximum system frequency of 350 MHz and features nonvolatile flash technology that retains configuration data when powered off.

Feature Summary

• High-performance reprogrammable flash technology enabling live at power-up functionality without external configuration memory
• Integrated embedded flash memory with configurable datapath for user data storage and secure in-system programming
• Mixed-signal capabilities including an integrated analog-to-digital converter and high-voltage tolerant I/Os

Applications

• Industrial control systems requiring nonvolatile configuration and mixed-signal processing
• Automotive electronics utilizing high-voltage input tolerance and robust flash technology
• Telecommunications infrastructure employing high-speed differential signaling standards

Procurement Notes

Verify the specific ordering suffix to confirm temperature range and RoHS compliance status, as variations exist within the Fusion family. Confirm package pinout compatibility with existing PCB footprints before procurement. Ensure the selected variant matches the required I/O voltage levels and speed grade for the target application environment.

Selection Notes

Select this component for applications demanding nonvolatile FPGA configuration combined with embedded analog functions. Compare against SRAM-based FPGAs if power consumption during standby is critical, as flash technology eliminates configuration reload overhead. Evaluate the integrated ADC resolution and channel count against specific signal conditioning requirements to determine if external components are necessary.

Part Context

This part belongs to the Actel/Microsemi Fusion mixed-signal FPGA family, which integrates standard digital logic with analog peripherals on a single chip. It succeeds earlier ProASIC families by offering higher gate counts and enhanced security features while maintaining low power consumption through its flash-based architecture.

Replacement Considerations

Direct pin-compatible replacements within the same package include other members of the Fusion AFS600 series, such as the M1AFS600 variants, provided the speed grade and temperature rating match. Cross-family migration to PolarFire or SmartFusion requires schematic and code adaptation due to architectural differences.
