Bit Brick SSOM-3576 Datasheet
1. Product Introduction
Bit-Brick SSOM-3576 is a high-performance System-on-Module (SoM) built around the Rockchip RK3576 processor, designed for intelligent terminals, industrial control systems, and edge computing applications,etc.
The module features a heterogeneous octa-core CPU architecture, integrates quad-core Cortex-A72 and quad-core Cortex-A53, with clock speeds up to 2.2GHz. It integrates an ARM Mali-G52 MP4 GPU, delivering robust capabilities for multitasking and advanced graphics processing. A built-in Neural Processing Unit (NPU) with 6 TOPS of AI computing power enables efficient on-device inference for AI workloads, supporting applications such as computer vision and intelligent interaction at the edge.
The module incorporates a rich set of high-speed interfaces, including Gigabit Ethernet, PCIe 2.1, USB 3.0, and MIPI DSI/CSI, facilitating flexible peripheral expansion and system integration. It supports ultra-high-definition video decoding up to 4K@120fps and multi-display configurations, including both mirrored and independent output modes, addressing a wide range of multimedia and display-centric use cases.
With its low power consumption, high stability, and excellent scalability, the SSOM-3576 is ideally suited for deployment in smart retail terminals, industrial panel PCs, AI-powered vision systems, and smart home control hubs, offering developers a reliable and efficient embedded hardware platform.
