16.2.3 AC Characteristics
Table 16.3 lists the control signal timing, and tables 16.4 lists the serial interface timing of the
H8/38024.
Table 16.3 Control Signal Timing
V_CC = 1.8 V to 5.5 V, AV_CC = 1.8 V to 5.5 V, V_SS = AV_SS = 0.0 V, T_a = –20°C to +75°C (regular
specifications), T_a = –40°C to +85°C (wide-range specifications), T_a = +75°C (Die) (including
subactive mode) unless otherwise indicated.
