Not Recommended For New Designs

The 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 RDK-S2E 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 cable length (typically 10m). Simply installing a Stellaris® 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, tinyform-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 offered in a small BGA package and integrates the 10/100 Ethernet MAC and PHYon-chip.

Features

The RDK-S2E ships with the MDL-S2E module. The MDL-S2E is aready-for-production serial-to-Ethernet module with the following features:

• LM3S6432 in a 10 x 10 mm BGA package for reduced board size
• 10/100 Mbit Ethernet port
• Auto MDI/MDIX cross-over correction
• Traffic and link indicators Serial ports
• UART ports include RTS/CTS for flow control
• UART0 has RS232 levels, transceiver runs at up to 230.4 Kbaud
• UART1 has CMOS/TTL levels, can run at 1.0 Mbaud

• IP configuration with static IP address or DHCP
• Telnet server for access to serial port (VCP software included)
• Web server for module configuration
• UDP responder for device discovery
• Telnet client for Ethernet-based serial port extender
• Module supports 5 V and 3.3 V supplies
• Multiple mounting options
• JTAG port pads for factory programming
