What is a System-on-Module (SoM)?

SoM is short for system on module. It’s an electronic circuit and integrates all required system functions into a module, including processor, storage (eMMC or Flash), memory (DDR) and I/O controller. However, unlike SoC that combines many of these functions onto a single chip, SoM typically requires only power to operate. In short, a SoM packages core computing capabilities into a compact, ready-to-use module. Most SoMs integrate the CPU, memory, storage, and board-to-board (B2B) connectors/edge contacts. It’s connected to a matching carrier board through pins to implement a system-on-a-chip in a certain field.

What is a System-on-Chip (SoC)?

SoC is short for system on chip, which is an integrated circuit (also known as a "chip") that integrates all or most components of a computer or other electronic system. These components typically (but not always) include a central processing unit (CPU), memory, input/output interfaces, and secondary storage interfaces-- all on a single substrate or microchip, size of a coin. It may contain digital, analog, mixed-signal, and often RF signal processing functions, depending on the applications. As integrated on a single substrate, SoC consumes significantly less power and occupies much less area than an equivalent multi-chip design. It can perform a variety of functions, including signal processing, wireless communications, artificial intelligence. SOC is commonly used in embedded systems and IoT.

Why Choose a System-on-Module for Your Project?

SoMs are easy-to-use embedded electronic hardware that can be integrated with substrates. When choosing a SoM, you should consider several factors, like specification, scalability, and flexibility, which are fundamental factors of any SoM that can impact your application. SoMs significantly reduce time-to-market and minimize costs, and make development much easier for engineers. With a SoM, all you need is a carrier board that fits your application to come into use.

SoMs offer significant advantages for hardware engineers and product manufacturers:

• Mitigate Design Complexity: Bypass intricate high-speed PCB routing and memory integration.
• Simplify Manufacturing: Reduce your BOM complexity and guarantee higher production yield rates.
• Accelerate TTM: Enable parallel hardware and software development to launch products months faster.
• Leverage Proven BSPs: Skip low-level driver debugging with our pre-compiled Linux and Android images.
• Out-of-the-Box Connectivity: Rely on pre-validated industrial protocols and interfaces for seamless integration.

SoM vs. SoC: What is the Difference?

Feature	System-on-Chip (SoC)	System-on-Module (SoM)
Form Factor	Single Silicon Chip	Complete PCB Module
Design Complexity	Extremely High (requires complex PCB routing)	Low to Medium (only carrier board design needed)
Time-to-Market	Longer (12-18 months)	Faster (3-6 months)
Development Cost	High upfront engineering costs	Lower upfront costs; highly cost-effective for low-to-mid volume
Best For	High-volume consumer electronics, ultra-custom designs	Industrial controllers, medical devices, Edge AI, rapid prototyping
