Condition A: V_CC = PLLV_CC = 3.0 V to 3.6 V, PV_CC = 3.0 V to 5.5 V, AV_CC = 3.6 V to 5.5 V*¹,
V_ref = 3.6 V to AV_CC*², V_SS = AV_SS = PLLV_SS = 0 V, ø = 2 to 16 MHz, T_a = –20°C
to +75°C (regular specifications), T_a = –40°C to +85°C (wide-range specifications)
Condition B: V_CC = PLLV_CC = 3.0 V to 3.6 V, PV_CC = 4.5 V to 5.5 V, AV_CC = 4.5 V to 5.5 V,
V_ref = 4.5 V to AV_CC, V_SS = AV_SS = PLLV_SS = 0 V, ø = 2 to 25 MHz, T_a = –20°C to
+75°C (regular specifications), T_a = –40°C to +85°C (wide-range specifications)
