The Stellaris® LM3S2139 microcontroller is based on the ARM® Cortex™-M3 controller core operating at up to 25 MHz, with 64 kB flash and 16 kB SRAM. The LM3S2139 also features real-time industrial connectivity, with a CAN controller, an SSI / SPI controller, an I2C interface, and 2 UARTs. The microcontroller also features intelligent analog capability, including 3 analog comparators and 4 channels of highly accurate 10-bit analog-to-digital conversion - with the ability to sample at speeds of 250K samples per second. Finally, the LM3S2139 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 56 GPIOs.
