The Stellaris® LM3S818 microcontroller is based on the ARM® Cortex™-M3 controller core operating at up to 50 MHz, with 64 kB flash and 8 kB SRAM. The LM3S818 also features real-time industrial connectivity, with an SSI / SPI controller, and 2 UARTs. The LM3S818 microcontroller also features advanced motion control features, including 6 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 1 analog comparators and 6 channels of highly accurate 10-bit analog-to-digital conversion - with the ability to sample at speeds of 1M samples per second. Finally, the LM3S818 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 30 GPIOs.
