LM3S1538-IQC50-A2 Frequently Asked Questions (FAQs)

  • The recommended crystal oscillator frequency for the LM3S1538 is 12 MHz, but it can operate with a frequency range of 10 MHz to 20 MHz.
  • The GPIO pins can be configured as analog or digital inputs using the Analog Mode Select (AMS) register and the Digital Function Select (DFS) register. Refer to the device's user manual for specific register settings.
  • The maximum current that can be sourced or sunk by a GPIO pin is 4 mA. However, it's recommended to limit the current to 2 mA to ensure reliable operation.
  • The internal flash memory can be used for data storage by using the Flash Memory Controller (FMC) module. The FMC provides a set of registers to read, write, and erase the flash memory. Refer to the device's user manual for specific programming examples.
  • The power consumption of the LM3S1538 varies depending on the operating mode. In active mode, the typical current consumption is around 20 mA at 50 MHz. In sleep mode, the typical current consumption is around 10 uA. Refer to the device's datasheet for specific power consumption values.
