14.8.5 LCD Characteristics
Table 14.37 lists the LCD characteristics, and table 14.38 lists the AC characteristics for external
segment expansion of the H8/3833 and H8/3834.
Table 14.37 LCD Characteristics of H8/3833 and H8/3834
V_CC = 2.7 V to 5.5 V, AV_CC = 2.7 V to 5.5 V, V_SS = AV_SS = 0.0 V, T_a = –20°C to +75°C, including
subactive mode, unless otherwise specified.

Notes: 1. These are the voltage drops between the voltage supply pins V₁, V₂, V₃, and V_SS, and
the segment pins or common pins.
2. When V_LCD is supplied from an external source, the following relation must hold:
V_CC ≥ V₁ ≥ V₂ ≥ V₃ ≥ V_SS
