The Qualcomm Dragonwing™ Q-4390 processor series enables a flexible platform that delivers edge processing, LPDDR5, 5G, Wi-Fi 6E, and software-configurable options, letting you scale across product lines without hardware redesign.

Manufacturers building connected devices for industrial, retail, and home applications need to support a growing mix of connectivity, memory, and performance requirements. A single product line may include 5G, 4G, Wi-Fi, LPDDR4x, LPDDR5, quad-core, or octa-core configurations. When each variation becomes a separate platform, companies add board design work, software maintenance, validation cycles, inventory planning, and launch complexity.

The Dragonwing Q-4390 processor helps simplify that model with a configurable platform approach...
