4.11.3 Clock Specifications The CC3200 device requires two separate clocks for its operation: • A slow clock running at 32.768 kHz is used for the RTC. • A fast clock running at 40 MHz is used by the device for the internal processor and the WLAN subsystem. The device features internal oscillators that enable the use of cheaper crystals rather than dedicated TCXOs for these clocks. The RTC can also be fed externally to provide reuse of an existing clock on the system and reduce overall cost. 4.11.3.1 Slow Clock Using Internal Oscillator The RTC crystal connected on the device supplies the free-running slow clock. The accuracy of the slow clock frequency must be 32.768 kHz ±150 ppm. In this mode of operation, the crystal is tied between RTC_XTAL_P (pin 51) and RTC_XTAL_N (pin 52) with a suitable load capacitance.
