Description
The WO1602L is a COG 16x2 Character LCD Display equipped with an ST7032Ai controller IC and supports an I2C serial interface. The logic power supply voltage is 3V or 5V, and it operates with a 1/16 driving duty. With outline dimensions of 62.8 x 23 mm, the display provides a view area of 51.5 x 12.23 mm and an active area of 47.6 x 9.74 mm.
This module can operate at temperatures ranging from -20℃ to +70℃, and its storage temperatures range from -30℃ to +80℃. The LCD COG display is particularly suitable for applications that demand more compact package displays. It's important to note that the WO1602L serves as an alternative model for WO1602H in case of IC shortages or longer lead times.

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 |
