Texas Instruments: EKT-LM3S6965 Ethernet Evaluation Kit for Stellaris LM3S6965 Microcontroller

Kit Overview

The Stellaris LM3S6965LM3S6965 Evaluation Board (EKT-LM3S6965EKT-LM3S6965) is a compact and versatile evaluation platform for Ethernet enabled Stellaris LM3S6965 ARM Cortex-M3 based microcontroller. The evaluation kit uses the LM3S6965 microcontroller’s fully integrated 10/100 Ethernet controller to demonstrate an embedded web server. You can use the board either as an evaluation platform or as a low-cost in-circuit debug interface(ICDI). Each board has an In-Circuit Debug Interface (ICDI) that provides hardware debugging functionality not only for the on-board Stellaris devices, but also for any Stellaris microcontroller-based target board. In debug interface mode, the on-board microcontroller is bypassed, allowing programming or debugging of an external target.

The kit is also compatible with high-performance external JTAG debuggers. This evaluation kit enables quick evaluation, prototype development, and creation of applicationspecific designs for Ethernet networks. The kit also includes extensive source-code examples, allowing you to start building C code applications quickly.

The heart of the EVB is a Stellaris LM3S6965LM3S6965 ARM Cortex-M3 based microcontroller operating at up to 50 MHz, with 256 kB flash and 64 kB SRAM. The LM3S6965 also features real-time industrial connectivity, with a 10/100 Ethernet MAC/PHY, an SSI / SPI controller, 2 I2C interfaces, and 3 UARTs. The LM3S6965 microcontroller also features advanced motion control features, including 6 motion-control PWM outputs with dead-band, two quadrature encoder inputs for precise position monitoring, and 1 fault protection inputs for low-latency shutdown. The microcontroller also features intelligent analog capability, including 2 analog comparators and 4 channels of highly accurate 10-bit analog-to-digital conversion - with the ability to sample at speeds of 1M samples per second. Finally, the LM3S6965 microcontroller provides a 24-bit systick timer, 4 32-bit or 8 16-bit general-purpose timers, a watchdog timer, a battery-backed hibernation module with RTC and 256 bytes of non-volatile state-saving memory, a low drop-out voltage regulator so that only one supply voltage is required, brown-out reset, power-on reset controller, and up to 42 GPIOs.
