74.7.6 Slow RC Oscillator

Table 74-50. Slow RC Oscillator Characteristics
Symbol	Parameter	Conditions	Min	Max	Unit
V_BAT	Supply voltage range (VBAT)⁽¹⁾	–	V_IT-	3.6	V
f_SLOWRC	Frequency accuracy	VBAT = 3.3V, T_J = 0 to +50°C	30.5	33.5	kHz
		VBAT = V_IT- to 3.6V, over the applicable T_J range	29	37	kHz
		VBAT = VIT- to 3.6V, T_J = -40 to +105°C	29	35	kHz

Note:

In this table, V_IT- refers to the negative-going input threshold voltage of the VBAT POR (see the table VBAT POR Characteristics). The operation of the backup section of the device, and in particular of the slow RC oscillator, is granted down to the VBAT POR V_IT- threshold.
