Control Signal Timing

Condition A: V

CC = 2.7 V to 5.5 V, AVCC = 2.7 V to 5.5 V, Vref = 2.7 V to AVCC,

SS = AVSS = 0 V, φ = 32 kHz to 10 MHz, Ta = –20 to +75°C (regular

specifications), T

a = –40 to +85°C (wide-range specifications)

Condition B: V

CC = 2.7 V to 5.5 V, AVCC = 2.7 V to 5.5 V, Vref = 2.7 V to AVCC,

SS = AVSS = 0 V, φ = 32 kHz to 13 MHz, Ta = –20 to +75°C (regular

specifications), T

a = –40 to +85°c (wide-range specifications)

Condition C: V

CC = 5.0 V ±10%, AVCC = 5.0 V ±10%, Vref = 4.5 V to AVCC,

SS = AVSS = 0 V, φ = 2 to 20 MHz, Ta = –20 to +75°C (regular specifications),

a = –40 to +85°C (wide-range specifications)
