Table 22-36 Clock Timing
Condition B: V_CC = 5.0 V ± 10%, AV_CC = 5.0 V ± 10%, V_ref = 4.5 V to AV_CC,
V_SS = AV_SS = 0 V, ø = 2 to 20 MHz, T_a = –20 to +75°C (regular specifications),
T_a = –40 to +85°C (wide-range specifications)
Condition C: V_CC = 3.0 to 5.5 V, AV_CC = 3.0 to 5.5 V, V_ref = 3.0 V to AV_CC,
V_SS = AV_SS = 0 V, ø = 2 to 13 MHz, T_a = –20 to +75°C (regular specifications),
T_a = –40 to +85°C (wide-range specifications)
