Description

The tiny-footprint Stellaris® Serial-to-Ethernet Module (MDL-S2E) offers a complete, ready-to-implement solution designed to add web connectivity to any serial device. 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 cable length (typically 10 m). Simply installing a Stellaris® Serial-to-Ethernet Module into the legacy serial device provides many benefits including no majorboard redesign or software changes, easy sharing on a network other than Ethernet, tiny form-factor for unobtrusive implementation, and 10-meter maximum cable length for serial connections is no longer a limitation.

The MDL-S2E is the first serial-to-Ethernet converter available with 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 Stellaris® microcontroller is offeredin a small BGA package and integrates the 10/100 Ethernet MAC and PHYon-chip.
