14.5.5 LCD Characteristics
Table 14.22 lists the LCD characteristics, and table 14.23 lists the AC characteristics for external
segment expansion of H8/3832S, H8/3833S, and H8/3834S (wide temperature range (I-spec)
version).

Temperature Range (I-Spec) Version)
V_CC = 2.5 V to 5.5 V, AV_CC = 2.5 V to 5.5 V, V_SS = AV_SS = 0.0 V, T_a = –40°C to +85°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
