system on a module concept:

SoM – "System-on-Module". SoM is comprised of a small processor module with CPU bus accessibility and standard I/O functionality. SoM is an ideal alternative to custom engineering. With a SoM approach you get the best of aspects of both buying an Off-The-Shelf Single Board Computer (SBC) and of a Custom Engineered solution. Unlike an SBC (Single Board Computer) which includes a set of standard connectors (e.g. Power, USB, Ethernet, etc), the SOM requires a matching a carrier board (or "baseboard") in order to establish a complete system. SOM-based Base-board enables a flexible design, while keeping most of the “off the shelf” SBC advantages (e.g. Time to market , cost-effective solution and proven software support)

Variscite's SOMs are low-power, high performance System-on-Modules which serve as building blocks and easily integrate into any embedded solution. They include an extensive range of interfaces and communication protocols and are ready to run any embedded operating system such as Linux and Windows Embedded CE

Variscite SOMs are widely used in a variety of fields, such as: Medical, Agriculture, Industrial computing, Military and consumer products.

SOM Advantages:

Design Challenges &
Resources SOM Integration MCU Integration

Hardware

Documentation Simplified Data Sheet Complex documentation

Reference Design Simple, cost-sensitive, ORCAD DSN format.
Design review – Variscite offers schematic
review to each of its customers. Available

Design Flexibility Medium High

Design Complexity Low High – DDR interface, power management
..etc.

Layout Simple, 4-6 layers, no micro-vias required,
Signal integrity -> lower risk and cost Complex (DDRs, Complex power lines..)
Micro vias in large size PCBs -> high cost
Signal integrity done by customer

Bring Up Short Process, focus in application specific
peripherals. Long HW -SW integration process of basic
MCU peripherals.

Hardware upgrades
(CPU Speed, memory Size) Variscite SOMs are pin-2-pin compatible ->
Replacing SOM Full project re-spin.

Software

Device Drivers Rich feature set, proven, device drivers for
all common peripherals tested by over 100
customers. Device drive modifications required, long
debug & QA process.

Software Features Unique features such as: Remote software,
upgrades, manufacturing servers for
concurrent burning at production…etc. Poor basic features supplied by IC vendor.

Software upgrades, BSP
maintenance. Free Costly design process
