Overview


The SoM-400EM is based on the 8051 code compatible Maxim/Dallas™ DS80C400 TINI® processor. The Tiny InterNet Interface (TINI®) processor is a Java programmable processor that is ideal for use in Internet appliances and Web based applications.

This 8-bit 8051 code compatible processor has an Ethernet MAC built-in along with 3 serial ports. It can directly access 16 MB of memory and has a UNIX type OS that features a complete file system.

The only drawback to this processor was that it does not have a hardware SPI port. To overcome this drawback, EMAC designed a PLD SPI engine that connects directly to the processor's data bus. This allows the EMAC SoM-400EM to meet customer SPI speed requirements, that a bit-banged SPI could not. EMAC also added a programmable oscillator and 10 general-purpose digital I/O lines to this SoM.

Using the same SODIMM form-factor that Maxim/Dallas™ used on their reference board, EMAC then added additional higher speed memory, an Ethernet PHY, a hardware SPI port, and digital I/O lines. EMAC also wrote a custom native SPI driver to support the hardware SPI port. A special version of the board can be purchased that is backwards compatible with the Maxim/Dallas™ reference board.

Since the SoM-400EM normally runs a Java Interpreter, it can tend to be slow executing certain tasks. In order to provide more throughput for the customers that need it, EMAC has designed a hardware compatible 32-bit SoM which can offer the user a higher speed alternative.

The SoM-400EM 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 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, and Modem interfaces. The off-the-shelf Carrier Board (SoM-100ES) allows the user to immediately start coding their application using a powerful Embedded Java Compiler and Tools.

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