The Stellaris® LM3S2620 microcontroller is based on the ARM® Cortex™-M3 controller core operating at up to 25 MHz, with 128 kB flash and 32 kB SRAM. The LM3S2620 also features real-time industrial connectivity, with 2 CAN controllers, an SSI / SPI controller, an I2C interface, and a UART. The LM3S2620 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. Finally, the LM3S2620 microcontroller provides a 24-bit systick timer, 4 32-bit or 8 16-bit general-purpose timers, a watchdog timer, a battery-backed hibernation module with RTC and 256 bytes of non-volatile state-saving memory, a low drop-out voltage regulator so that only one supply voltage is required, brown-out reset, power-on reset controller, and up to 52 GPIOs.
