The Stellaris® LM3S301 microcontroller is based on the ARM® Cortex™-M3 controller core operating at up to 20 MHz, with 16 kB flash and 2 kB SRAM. The LM3S301 also features real-time industrial connectivity, with an SSI / SPI controller, and a UART. The LM3S301 microcontroller also features advanced motion control features, including 2 motion-control PWM outputs with dead-band and 1 fault protection inputs for low-latency shutdown. The microcontroller also features intelligent analog capability, including 2 analog comparators and 3 channels of highly accurate 10-bit analog-to-digital conversion - with the ability to sample at speeds of 250K samples per second. Finally, the LM3S301 microcontroller provides a 24-bit systick timer, 2 32-bit or 4 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.
