Control Signal Timing

Table 21.5 lists the control signal timing.

Table 21.5 Control Signal Timing

Condition A: VCC = 2.7 to 5.5 V, AVCC = 2.7 to 5.5 V, Vref = 2.7 V to AVCC,

VSS = AVSS = 0 V, φ = 2 to 10 MHz, Ta = –20 to +75°C (regular specifications),

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

Condition B: VCC = 5.0 V ±10%, AVCC = 5.0 V ±10%, Vref = 4.5 V to AVCC,

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

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