LM3S317-IQN25-C2 Frequently Asked Questions (FAQs)

  • The recommended crystal oscillator frequency for the LM3S317-IQN25-C2 is 12 MHz, but it can operate with a frequency range of 10 MHz to 20 MHz.
  • To configure the JTAG interface, connect the TDI, TDO, TCK, and TMS pins to a JTAG debugger, and set the JTAG clock frequency to 10 MHz or less. Also, ensure that the JTAG pins are not used for other functions.
  • The maximum current that can be sourced or sunk by the GPIO pins is 4 mA per pin, with a total current limit of 100 mA for all GPIO pins combined.
  • The LM3S317-IQN25-C2 has a built-in watchdog timer that can be enabled and configured using the Watchdog Timer Control Register (WDTCTL). The watchdog timer can be set to timeout after a specified period, and can be reset using the WDTCTL register or an external reset signal.
  • The power consumption of the LM3S317-IQN25-C2 varies depending on the operating mode. In active mode, the power consumption is approximately 250 μA/MHz. In sleep mode, the power consumption is approximately 10 μA, and in deep sleep mode, it is approximately 1 μA.
