Table 17.12 shows the LCD characteristics.
Table 17.12 LCD Characteristics
One of following conditions is applied unless otherwise specified.
Condition A (F-ZTAT version): V_CC = 2.7 V to 3.6 V, AV_CC = 2.7 V to 3.6 V,
V_SS = AV_SS = 0.0 V
Condition B (F-ZTAT version): V_CC = 2.2 V to 3.6 V, AV_CC = 2.2 V to 3.6 V,
V_SS = AV_SS = 0.0 V
Condition C (Mask ROM version): V_CC = 1.8 V to 3.6 V, AV_CC = 1.8 V to 3.6 V,
V_SS = AV_SS = 0.0 V

Notes: 1. The voltage step-down from power supply pins V1, V2, V3, and V_SS to each segment pin
or common pin.
2. When the liquid crystal display voltage is supplied from an external power supply,
ensure that the following relationship is maintained: V_CC ≥ V1 ≥ V2 ≥ V3 ≥ V_SS.
