58.7.5 Slow RC Oscillator

Table 58-42. Slow RC Oscillator Characteristics
Symbol	Parameter	Conditions	Min	Typ	Max	Unit
V_DDBU	Supply voltage range (VDDBU)⁽¹⁾	–	V_IT-	–	3.6	V
f_SLOWRC	Frequency accuracy	VDDBU = 3.3V, T_J = 0 to +50°C	31	32	33	kHz
f_SLOWRC	Frequency accuracy	VDDBU = V_IT- to 3.6V T_J = -40 to +125°C	29	–	35	kHz

Note:

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