AFS600-1FG484K

Overview

The AFS600-1FG484K is a Field Programmable Gate Array from the Microsemi Fusion family, manufactured by Microchip Technology. It features 600,000 equivalent system gates and 13,824 configurable logic blocks (CLBs). The device utilizes a nonvolatile Flash-based CMOS process with a 130-nm technology node. It operates on a single 3.3 V supply with an internal 1.5 V regulator. The package is a 484-pin Plastic Ball Grid Array (PBGA) with a 1.0 mm pitch. The industrial temperature range extends from -40 °C to +100 °C. Maximum system performance reaches 350 MHz.

Feature Summary

• Nonvolatile Flash-based architecture enables Live at Power-Up (LAPU) functionality without external configuration memory.
• Integrated mixed-signal capabilities including an analog-to-digital converter (ADC) and high-voltage tolerant I/Os.
• Supports in-system programming via JTAG with optional 128-bit AES encryption for content security.
• Includes embedded user flash memory for data storage and code execution.

Applications

• Industrial control systems requiring deterministic boot-up and mixed-signal processing.
• Automotive electronics utilizing high-voltage tolerant I/O interfaces.
• Telecommunications infrastructure equipment needing secure reprogrammable logic.
• Medical devices integrating analog signal acquisition with digital logic control.

Procurement Notes

Verify the specific suffix 'K' against official Microchip documentation to confirm if it denotes a specific environmental rating or packaging variant distinct from standard commercial grades. Ensure compatibility with existing board layouts regarding the 484-pin BGA footprint and thermal requirements. Confirm RoHS compliance status through the manufacturer's current product change notices.

Selection Notes

Select this component when nonvolatile configuration and mixed-signal integration are required within a high-density FPGA. Compare gate counts and I/O voltage levels against alternative Fusion family members like the M1AFS600 series. Evaluate the need for ARM core support; if processor integration is unnecessary, the pure logic AFS600 offers a simpler design path. Verify pin compatibility with legacy Actel designs if migrating existing projects.

Part Context

This part belongs to the Actel Fusion family, bridging the gap between traditional Flash FPGAs and complex SoCs. It succeeds earlier ProASIC technologies while preceding the more integrated SmartFusion and IGLOO2 lines. The Fusion platform is characterized by its ability to embed analog peripherals directly into the programmable fabric, distinguishing it from purely digital FPGA competitors.

Replacement Considerations

Direct pin-compatible replacements within the same package include other variants of the AFS600 series, such as the AFS600-1FG484I for industrial temperature ranges. Cross-family migration to the IGLOO2 or SmartFusion2 families requires schematic redesign due to architectural differences and pinout changes.
