TM4C123GH6PM -Minimum clock frequency

Hi

1) Can this device  be clocked on the internal 30KHz oscillator in run mode with PLL off?  I need to run the device slow at certain times.

2) Can the ADC be clocked at a lower frequency other than 16Mhz?

Regards

    Hello Nikhil,

    Yes, it is possible to run the device of 30K with PLL off. However it would be better to instead using the Deep Sleep as that would result in lower current consumptions due to other power saving options, like LDO scaling, clock scaling, and memory low power.

    The ADC is fixed for option of MOSC or PLL divided clock
