The RK3399K is manufactured by Rockchip, a Chinese semiconductor company specializing in system-on-chip (SoC) designs for consumer electronics. Founded in 2001 and headquartered in Fuzhou, Rockchip produces ARM-based processors used in tablets, smart TVs, IoT devices, and single-board computers (like the Rock Pi 4). The RK3399K is a variant of the RK3399, optimized for AI and edge computing applications. Rockchip is known for cost-effective, mid-range chips but lacks the global brand recognition of Qualcomm or MediaTek.

The RK3399K, a high-performance SoC by Rockchip, is widely used in:
1. Single-board computers (e.g., Rock Pi 4, NanoPC-T4).
2. AI edge computing (NPU for lightweight ML tasks).
3. Industrial automation (robotics, control systems).
4. Digital signage & kiosks (4K video playback).
5. Gaming & entertainment (ARM-based consoles, media centers).
6. IoT gateways (data processing hubs).
7. Embedded vision (drones, surveillance cameras).
Its dual-core Cortex-A72 + quad-core A53 CPU and Mali-T864 GPU make it ideal for multitasking and multimedia applications.

The RK3399K is typically available in a TFBGA (Thin Fine-Pitch Ball Grid Array) package. This compact, surface-mount package is designed for high-performance applications, featuring multiple pins for connectivity and efficient heat dissipation. It is commonly used in embedded systems, single-board computers, and AIoT devices. The exact pin count and dimensions may vary slightly depending on the manufacturer.
