●The Stellaris® LM3S6911 microcontroller is based on the ARM® Cortex™-M3 controller core operating at up to 50 MHz, with 256 kB flash and 64 kB SRAM. The LM3S6911 also features real-time industrial connectivity, with a 10/100 Ethernet MAC/PHY, 2 SSI / SPI controllers, 2 I2C interfaces, and 3 UARTs. Finally, the LM3S6911 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 46 GPIOs.
● 32-bit ARM® Cortex™-M3 50-MHz processor core with System Timer (SysTick), integrated Nested Vectored Interrupt Controller (NVIC), Memory Protection Unit (MPU), and Thumb-2 instruction set
● Full-featured debug solution with debug access via JTAG and Serial Wire interfaces, and IEEE 1149.1-1990 compliant Test Access Port (TAP) controller
● 256 KB single-cycle flash and 64 KB single-cycle SRAM
● Lower-power battery-backed Hibernation module with Real-Time Clock
● 10-46 GPIOs (depending on configuration) with programmable control for GPIO interrupts and pad configuration
● ARM FiRM-compliant Watchdog Timer ; plus four General-Purpose Timer Modules (GPTM), each of which provides two 16-bit timers/counters and can be configured to operate independently
● 10-bit Analog-to-Digital Converter (ADC) with analog input channels and a sample rate of samples/second
