Bus Timing: Table 20.16 lists the bus timing.
Table 20.16 Bus Timing
Condition A: VCC = AVCC = 2.7 to 5.5 V, Vref = 2.7 V to AVCC, VSS = AVSS = 0 V,
ø = 2 to 10 MHz, Ta = â20 to +75°C (regular specifications),
Ta = â40 to +85°C (wide-range specifications)
Condition B: VCC = AVCC = 5.0 V ± 10%, Vref = 4.5 V to AVCC, VSS = AVSS = 0 V,
ø= 2 to 20 MHz, Ta = â20 to +75°C (regular specifications),
Ta = â40 to +85°C (wide-range specifications)
