The Luminary Micro Stellaris Serial-to-Ethernet Reference Design Kit (RDK-S2E) offers a complete, open-tool, and ready-to-implement solution designed to add Web connectivity to any serial device.
Included in the kit is the tiny-footprint Stellaris Serial-to-Ethernet Module (MDL-S2E). The most common application for the MDL-S2E is for augmenting legacy products that only contain a serial port for a configuration or control interface. In addition, newer computers, especially laptop computers, do not necessarily have serial ports, and a serial connection is limited by a typical cable length of 10 metres. Simply installing a Serial-to-Ethernet Module into the legacy serial device provides many benefits including no major board redesign or software changes, easy sharing on a network other than Ethernet, tiny form-factor for unobtrusive implementation, and the 10-metre maximum cable length for serial connections is no longer a limitation.
The MDL-S2E features a highly integrated ARM Cortex-M3 microcontroller with 50 MHz of performance and ample single-cycle, on-chip Flash and SRAM memory for efficient network traffic handling. For maximum space savings, the microcontroller is offered in a small BGA package and integrates the 10/100 Ethernet MAC and PHY on-chip.
