The Stellaris® LM3S102 microcontroller is based on the ARM® Cortex™-M3 controller core operating at up to 20 MHz, with 8 kB flash and 2 kB SRAM. The LM3S102 also features real-time industrial connectivity, with an SSI / SPI controller, an I2C interface, and a UART. Finally, the LM3S102 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 18 GPIOs.
