AFS1500-FG484I: Mixed-Signal SoC FPGA

November 9, 2025
AFS1500-FG484I

In the world of embedded systems, integrating digital processing, analog functionality, and secure control into a single chip can drastically reduce design complexity, power consumption, and cost. The AFS1500-FG484I from Microchip’s Fusion family is engineered for exactly that — a true SoC FPGA that combines logic fabric, analog peripherals, and Flash-based configuration for high-reliability, low-power embedded applications.

At DRex Electronics, we support developers and OEMs across industries by delivering components like the AFS1500-FG484I quickly and reliably, helping streamline development and supply chain continuity.

 

What is the AFS1500-FG484I?

The AFS1500-FG484I is a Flash-based System-on-Chip (SoC) FPGA that integrates 150,000 system gates with analog capabilities, such as ADCs, temperature sensing, and PLLs. It also features Flash configuration memory, security features, and a rich set of I/Os. Built on the Actel Fusion architecture (now Microchip), it is one of the first devices to merge mixed-signal analog, digital logic, and power management on a single chip.
