Custom Engineering & Manufacturing

System on a module (SoM) is an ideal alternative to custom engineering. With an SoM approach you get the best of aspects of both buying Off-The-Shelf and of a Custom Engineered solution.

An SoM is comprised of a small processor module with CPU bus accessibility and standard I/O functionality. The SoM module does not have any connectorization and is designed to be plugged into a Carrier Board. The Carrier board contains the I/O connectors as well any other I/O requirement not provided on the SoM itself.

This approach allows the customer to design a Custom Carrier Board, that meets the customer's I/O, dimensional, and connector requirements without having to worry about the processor, memory, and standard I/O functionality.

If the customer does not have the ability to design the Custom Carrier board in-house, EMAC's Custom to Order Service (COS) can economically produce a Custom Carrier for you. By utilizing a library of standard I/O modules EMAC can typically deliver Carrier prototypes in 1 to 2 months and also meet your production delivery needs in the future. EMAC also offers Off-The-Shelf Carrier boards for SoM evaluation and early software development.

There are two families of SoMs. The microcontroller family offers a very inexpensive and small size solution for Data Accusation and Control, Internet Appliance and Web applications. The x86 family offers PC compatibility with embedded features such as Flash Disk and LCD video. An advantage of the SoM design approach is that within each family of SoMs there are several processor choices. This allows the user to select a low-end processor for initial deployment and upgrade later to a higher end processor as features and need demands.

SoM Benefits

• Faster time to market
• Cost savings
• Reduced risk
• Scalable CPU choices
• Decreased customer design requirements
• Small footprint
