FMPLL electrical characteristics

The device provides a frequency-modulated phase-locked loop (FMPLL) module to generate a fast system

clock from the main oscillator driver.

2 This is the recommended range of load capacitance at OSC32K_XTAL and OSC32K_EXTAL with respect to

ground. It includes all the parasitics due to board traces, crystal and package.

3 Maximum ESR (R

m) of the crystal is 50 kΩ

4 C0 includes a parasitic capacitance of 2.0 pF between OSC32K_XTAL and OSC32K_EXTAL pins

DD = 3.3 V ± 10% / 5.0 V ± 10%, TA = −40 to 125 °C, unless otherwise specified. Values are specified for no

neighbor GPIO pin activity. If oscillator is enabled (OSC32K_XTAL and OSC32K_EXTAL pins), neighboring pins

should not toggle.
