The SoM-NE64M is a 16-bit system on module (SoM) based on the ColdFire MC9S12NE64 processor. This 16-bit 68HC12-compatible processor has an Ethernet MAC and PHY built-in along with two serial ports. It features 64 KB of flash memory, 32 KB of EEPROM, and 8 KB of RAM. Another 512 KB of RAM can be added as an option.

All of this functionality is incorporated on a board smaller than a business card that uses less than 1 W of power. Applications for the SoM-NE64 can be programmed using GNU tools within an Eclipse IDE. Alternatively, the SoM-NE64 can be programmed using CodeWarrior.

Like other modules in the product line, the SoM-NE64M is designed to plug into a carrier board containing all the connectors and any additional I/O components that may be required. This approach allows the design of 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. Since the module itself has more functionality built in than many other SoM designs, the carrier board can be much easier to design and produce, lowering cost and time to market.  

In addition to the option of the developing a carrier board, one can be purchased off-the-shelf. Off-the-shelf carrier boards that feature A/D, D/A, MMC/SD card, keypad, LCD, and modem interfaces are currently available. The SoM approach provides the flexibility of a fully customized product at a greatly reduced cost.

The SoM-NE64M is ideal for any web/network data acquisition and control application. The SoM-NE64M costs $67.
