MPU System On Modules (SOMs)

Creating an industrial-grade microprocessor (MPU)-based system doesn’t have to require a great deal of design effort and complexity. System on Modules can significantly simplify your design by integrating the power management, nonvolatile boot memory, Ethernet PHY, high-speed (LP)DDR2 memory and optional wireless connectivity onto a small, single-sided Printed Circuit Board (PCB). These SOMs use a common set of proven Microchip components and limit the design rules of the main application board, reducing overall PCB complexity and cost. They have castellated mounting holes to enable easy hand soldering in your initial prototyping phase and automated board-to-board soldering in production.

You can solder the SOM on a motherboard and take your project to production, or you can use the free schematics, design and Gerber files and complete Bill of Materials (BOM)that are available in the Documents section  on the SOM’s product page, to create a reference design. You can also easily transition from the SOM to the SiP or the SAMA5D2 MPU itself, depending on your design needs. No matter which option you select, these devices are backed by Microchip’s client-driven obsolescence practice of continuing to supply a product for as long as possible and while demand for the product exists.
