LM3S2911-IQC50-A2 Frequently Asked Questions (FAQs)

  • The recommended crystal oscillator frequency for the LM3S2911 is 12 MHz, but it can operate with a frequency range of 10 MHz to 20 MHz.
  • The GPIO pins on the LM3S2911 can be configured using the GPIO peripheral registers. The GPIO pins can be configured as inputs or outputs, and can also be configured to have internal pull-up or pull-down resistors.
  • The maximum current that can be sourced or sunk by the GPIO pins on the LM3S2911 is 4 mA. However, it is recommended to limit the current to 2 mA to ensure reliable operation.
  • The ADC on the LM3S2911 is a 12-bit successive approximation register (SAR) ADC. It can be configured to convert analog signals on any of the 12 available ADC channels. The ADC can be triggered by a software command or by an external signal.
  • The maximum clock frequency that the LM3S2911 can operate at is 50 MHz. However, the clock frequency can be adjusted using the PLL (Phase-Locked Loop) or the clock divider to achieve lower frequencies.
