20.2.3 AC Characteristics
The following AC timing chart represents the AC characteristics, not signal functions. For signal
functions, see the explanation in the text.
(1) Clock Timing
Table 20.18 Clock Timing
Conditions: V_CC = 3.3 V ±0.3V, AV_CC = 3.3 V ±0.3V, AV_CC = V_CC ±0.3V, AV_ref = 3.0 V to
AV_CC, V_SS = AV_SS = 0 V, Ta = –20 to +75°C*
Note: * Regular-specification products; for wide-temperature-range products, Ta = –40 to +85°C
