The recommended crystal oscillator frequency for the LM3S601-IQN50-C2 is 12 MHz, but it can operate with a frequency range of 10 MHz to 20 MHz.
To configure the JTAG interface for debugging, connect the TDI, TDO, TCK, and TMS pins to a JTAG debugger, and ensure that the JTAG clock frequency is set to 10 MHz or less. Also, make sure to configure the JTAG pins as inputs in the GPIO configuration.
The maximum current that can be sourced or sunk by the GPIO pins of the LM3S601-IQN50-C2 is 4 mA per pin, with a total current limit of 100 mA for all GPIO pins combined.
To use the internal voltage regulator to power external components, connect the VCC pin to the external component's power pin, and ensure that the total current drawn from the regulator does not exceed 100 mA. Also, make sure to decouple the VCC pin with a 1 uF capacitor to prevent noise and oscillations.
The minimum operating temperature range for the LM3S601-IQN50-C2 is -40°C, and the maximum operating temperature range is 85°C.
