The four 10-bit ADC channels are enough for reading analog feedback from a potentiometer, a current-sense resistor, or a thermistor.
The supply range is 3.0 V to 3.6 V — single 3.3 V rail operation is straightforward.
That said, the Stellaris line has been part of TI's legacy portfolio for several years, so buyers planning a multi-year production run should monitor for any future PCN.
