20. Electrical Characteristics
20.2.2 AC Characteristics
Clock timing parameters are listed in table 20.6, control signal timing parameters in table 20.7,
and bus timing parameters in table 20.8. Timing parameters of the on-chip supporting modules are
listed in table 20.9.

Condition: T_a = –20°C to +75°C (regular specifications), T_a = –40°C to +85°C (wide-range
specifications)
Condition A: V_CC = 2.7 to 5.5 V, AV_CC = 2.7 to 5.5 V, V_REF = 2.7 to AV_CC, V_SS = AV_SS = 0 V,
φ = 1 to 10 MHz
Condition B: V_CC = 3.0 to 5.5 V, AV_CC = 3.0 to 5.5 V, V_REF = 3.0 to AV_CC, V_SS = AV_SS = 0 V,
φ = 1 to 13 MHz
Condition C: V_CC = 5.0 V ±10%, AV_CC = 5.0 V ±10%, V_REF = 4.5 to AV_CC, V_SS = AV_SS = 0 V,
φ = 1 to 20 MHz
