The Stellaris® LM3S3634 microcontroller is based on the ARM® Cortex-M3controller core operating at up to 50 MHz, with 128 kB flash, 32 kB SRAM,a 32-ch DMA, and ROM preloaded with the StellarisWare Driver Library andBootLoader. The LM3S3634 also features real-time industrial connectivity,with USB 2.0 Full Speed Host/Device, an SSI / SPI controller, 2 I2C interfaces,and 2 UARTs. The microcontroller also features intelligent analog capability,including 6 channels of highly accurate 10-bit analog-to-digital conversion- with the ability to sample at speeds of 500K samples per second. Finally,the LM3S3634 microcontroller provides a 24-bit systick timer, 3 32-bit or6 16-bit general-purpose timers, a watchdog timer, a battery-backed hibernationmodule with RTC and 256 bytes of non-volatile state-saving memory, a lowdrop-out voltage regulator so that only one supply voltage is required,brown-out reset, power-on reset controller, and up to 33 GPIOs.
