Q-4390
Q4

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...

Benefits

default icon alt text
Scale Across Product Lines
Use one configurable platform to support multiple device tiers, connectivity options, and price points.
default icon alt text
Reduce Hardware Redesigns
Support different product configurations through pin-compatible hardware SKUs and software-enabled feature packs, eliminating the need for separate board designs, BSPs, and validation cycles.
default icon alt text
Add Advanced Connectivity
Bring 5G, 4G, Wi-Fi 5, and Wi-Fi 6E to mid-tier IoT devices without moving to a higher-cost platform or changing the underlying architecture.
default icon alt text
Support LPDDR5 Designs
Address the transition from LPDDR4x to LPDDR5 with the most affordable Qualcomm IoT platform built to support both current and next-generation memory requirements.
default icon alt text
Control Cost by Configuration
Enable only the features each product requires through software licensing, aligning performance, connectivity, and cost across a broader device portfolio without over-provisioning hardware.
