APM sleep mode using slow clock with Ethernet PHY enabled: TBD Operating Temperature: -40 ~ 85° C (-40 ~ 185 ° F), fanless operation. Operating Humidity: 0% ~ 90% relative humidity, non-condensing SoM-3354M User Manual.docx Rev 1.4 © 2021 EMAC, Inc. -
Page 6: External Connections
The SoM-3354M connects to a carrier board containing its connectors, power supply and any expansion IO, through a standard gold-plated SODIMM 200-pin connection shown below. The use of the DDR SODIMM form-factor for EMAC’s SoMs is a sound choice that has been proven rugged and reliable in the laptop and embedded SBC markets. -

2.2.4. Ethernet The SoM-3354M provides a Micrel KSZ8041 Ethernet 10/100 PHY IC on board. Carrier designers need only to run these lines through the appropriate magnetics layer to have a functional Ethernet connection. Remember, the RX and TX lines are differential pairs and need to be routed as such. -

10111 UART0/USB0 Boot from Serial/USB. The SoM-3354M is capable of booting out of Serial, Ethernet, SPI Flash, or USB. Booting from eMMC is only possible with a custom populated version. Contact EMAC for more details. Minimum purchase quantities apply. 2.2.17. Power Connections The SoM-3354M requires a 3.3V supply for the bus and I/O voltages. -
Page 14: Design Considerations
3. Design Considerations One of the goals of the SoM-3354M is to provide a modular, flexible, and inexpensive solution capable of delivering high-end microcontroller performance. 3.1. The EMAC SoM Carrier-SoM-200ES EMAC provides an off the shelf carrier for the SoM-3354M module, the SoM-200ES, which provides power to the SoM module as well as wealth of peripheral I/O, including audio and LCD. -
Page 15: Software
4. Software The SoM-3354M offers a wide variety of software support from both open source and proprietary sources. The hardware core was designed to be software compatible with the TI AM3354 reference design, which is supported by Linux.
