Preliminary- Designed and manufactured in the USA, the DEV-SOM36 development kit is a IEEE 1588v2 Precision Time Protocol starting point.
The DEV-SOM36, an ultra-compact design with the TI DP83640 IEEE 1588 PTP PHYTER onboard, including an optional 4.3 inch WQVGA (480 x 272) TFT color LCD and a resistive touch screen for HMI applications. The dimensions of the DEV-SOM36 are 4.8” by 3.0”, about the same dimensions as that of popular touch cell phones. The DEV-SOM36 is small enough to fit in a 2U rack space or on the end of a 2U enclosure.
Standing above other panel PC options the DEV-SOM36 the second Ethernet Phy is ready for Precision Time Protocol (PTP) IEEE-1588 v1 and v2. The Texas Instruments TI DP83640 Real Time PHY offers many features to support Real time PTP networking as well as low latency time synchronization. IEEE 1588 Standards are known as Precision Clock Synchronization Protocol for Networked Measurement Control Systems, or PTP for short. IEEE-1588 PTP protocol allows clocks distributed across a wired network to accurately synchronize time by distributing time stamped messages between nodes. This synchronizing decreases the latency jitter between master and slave PTP systems.
Unlike other compact Panel PCs, the DEV-SOM36 comes with EMAC’s Embedded Linux distribution installed and fully configured on the onboard flash disk. This allows the software engineer to concentrate on writing applications and not have to worry about configuration and setup. Just apply power and watch the User Interface appear on the vivid color LCD, Linux X-Windows desktop. Interact with the DEV-SOM36 using the responsive, integrated touch screen.
The DEV-SOM36 compact Panel PC utilizes a System on Module (SoM) for the processing core. This allows the user to easily upgrade, if more memory capacity, storage capacity or processing power is required. The DEV-SOM36 includes an embedded ARM A8 SoM; this ARM System on Module features a 1GHz Fanless Low Power Processor with Video and Touch. The SoM provided with the DEV-SOM36 supports up to 512MB of Embedded SDRAM, Up to 16GB of embedded eMMC Flash, and 16MB of serial data flash. Typical power consumption is less than 5 Watts and the LED backlight can be shut off when not in use to further decrease its power consumption.
The DEV-SOM36 offers two RS-232 serial ports, and one RS232/422/485 port. Also provided are two USB 2.0 host ports, an Audio Beeper and a battery-backed real-time clock. A Micro SD card socket is provided for additional Flash storage. The DEV-SOM36 can be connected to a network using the 10/100 Base-T Ethernet controller and its onboard RJ-45 connector.
This approach allows clients to develop a product using a commercial off the shelf (COTS) system development/baseboard/carrier board for the proof of concept or production units. If the product or project has specific dimensional, I/O or connector placement requirements a custom carrier board can be created in as little as a month. Use of an off-the-shelf carrier board allows clients to start developing their software while the custom carrier board is being designed and build. Using the SoM approach, product lifecycle concerns for the processor, memory and other SoM based components are minimized.
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.
