The Stellaris® LM3S2678 microcontroller is based on the ARM® Cortex™-M3 controller 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 and BootLoader. The LM3S2678 also features real-time industrial connectivity, with a CAN controller, an SSI / SPI controller, and a UART. The LM3S2678 microcontroller also features advanced motion control features, including 4 motion-control PWM outputs with dead-band, a quadrature encoder input for precise position monitoring, and a fault protection input for low-latency shutdown. The microcontroller also features intelligent analog capability, including .8 channels of highly accurate 10-bit analog-to-digital conversion - with the ability to sample at speeds of 500K samples per second. Finally, the LM3S2678 microcontroller provides a 24-bit systick timer, 4 32-bit or 8 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 33 GPIOs.
