19. Electrical Characteristics
19.3 AC Characteristics
Clock timing parameters are listed in table 19.4, control signal timing parameters in table 19.5,
and bus timing parameters in table 19.6. Timing parameters of the on-chip supporting modules are
listed in table 19.7.

Condition: T_a = −20°C to +75°C (regular specifications), T_a = −40°C to +85°C (wide-range
specifications)
Condition A: V_CC = 3.0 to 3.6 V, AV_CC = 3.0 to 3.6 V, V_REF = 3.0 to AV_CC, V_SS = AV_SS = 0 V,
fmax = 25 MHz
Condition B: 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,
fmax = 20 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,
fmax = 25 MHz
