The Stellaris® LM3S2730 microcontroller is based on the ARM® Cortex-M3 controller core operating at up to 50 MHz, with 128 kB flash and 64 kB SRAM.The LM3S2730 also features real-time industrial connectivity, with a CAN controller, an SSI / SPI controller, and a UART.Finally, the LM3S2730 microcontroller provides a 24-bit systick timer, 3 32-bit or 6 16-bit general-purpose timers, a watchdog timer, a low drop-out voltage regulator so that only one supply voltage is required, brown-out reset, power-on reset controller, and up to 60 GPIOs.
