10.1.8.3 Slow RC Oscillator

Table 10-43. Slow RC Oscillator Characteristics
Symbol	Parameter	Conditions	Min	Max	Unit
V_DDBU	Supply voltage range (VDDBU)	–	V_IT-⁽¹⁾	3.60	V
f_SLOWRC	Output frequency range	V_DDBU = 3.3V, T_J = 0 to +50°C	31	33	kHz
f_SLOWRC	Output frequency range	V_DDBU = V_IT- to 3.6V	29	35	kHz

Note:

In this table, V_IT- corresponds to the negative-going input threshold voltage of the VDDBU POR (see VDDBU POR Characteristics table). Operation of the device backup section, and in particular of the Slow RC oscillator, is granted down to the VDDBU POR V_IT- threshold.
