Description

The SoM-9×25 is a System on Module (SoM) based on the Atmel AT91SAM9x25 processor. Designed and manufactured in the USA, this wide temperature, fanless ARM9 400 MHz SoM has an Ethernet PHY included along with 6 serial ports with auto RS-485. It utilizes up to 4GB of eMMC Flash, up to 16MB of serial data flash, and up to 128MB of DDR2 RAM. A SoM is a small embedded module that contains the core of a microprocessor system.

Using the same small 144 pin SODIMM form-factor utilized by other EMAC SoM modules, the SoM-9×25 is the ideal processor engine for your next design. All of the ARM processor core functionality is included on this tiny board including: Flash, Memory, Serial Ports, Ethernet, I2S Audio, PWMs, Timer/Counters, A/D, digital I/O lines, Clock/Calendar, and more.

The SoM-9×25 is designed to plug into a carrier board that contains all the connectors and any custom I/O required for the application. This approach allows the customer or EMAC 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. With this System on Module approach, a semi-custom hardware platform can be developed in as little as a month.

In addition to the option of the developing a custom carrier board, one can be purchased off-the-shelf from EMAC. EMAC provides off-the-shelf Carrier boards that feature A/D, D/A, MMC/SD card, keypad, LCD, Audio, and Modem interfaces. The recommended off-the-shelf Carrier Board for the SoM-9×25 is the SoM-150ES which allows the user to immediately start coding their application using the powerful Linux Operating System and Tools.

The System On Module approach provides the flexibility of a fully customized product at a greatly reduced cost.

___________________________________________________________________________

EMAC is a global leader in system on module and carrier board embedded systems.  The System on Module (SoM) is an ideal alternative to custom engineering. With the SoM approach you get the best of aspects of both buying an Off-The-Shelf Embedded Single Board Computer (SBC) and a Custom Engineered solution. With Off-The-Shelf embedded components such as a generic carrier board and SOM module, it is possible to start development on your software applications before the custom carrier board is complete; thus offering a reduced time to market for your system. A System on Module (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.
