SPECIFICATIONS

Interface Pin Function

Pin No. Symbol Description
1 VG VG is the LCD driving voltage for segment circuits.
VGO is the output of VG regulator. VGS is the feedback of VG regulator.
VGI is the VG input of segment circuits.
1.6 ≤ VG < VDD2.
2 XV0 XV0 is the LCD driving voltage for common circuits at positive frame.
XV0OUT is the output of XV0 regulator. XV0S is the feedback of XV0 regulator.
XV0I is the V0 input of common circuits
3 V0 V0 is the LCD driving voltage for common circuits at negative frame.
V0OUT is the output of V0 regulator. V0S is the feedback of V0 regulator.
V0I is the V0 input of common circuits.
Be sure that: V0 ≥ VG > VM > VSS ≥ XV0 (under operation).
4 VDD Power supply input.
5 VSS Ground
6 SDA Serial data input
7 SCL Serial clock input
8 RST Hardware reset input pin. When RSTB is “L”, internal initialization is executed
and the internal registers will be initialized.
