Winstar WO1602I is a COG monochrome LCD display module with 16 characters x 2 lines. The module has an outline dimension of 51.2 x 20.7 mm, featuring a view area size of 40.0 x 10.0 mm and an active area size of 38.0 × 8.0 mm. It is ideal for use in small electronic devices such as MP3 players, USB voltage and current detectors, digital calipers, electronic coffee scales, and more.

This series of monochrome LCD display modules is built-in with the ST7032I driver, and the interface is I2C. The supply voltage for logic is 3V or 5V, with a 1/16 driving duty. The module can operate at temperatures ranging from -20°C to +70°C, and its storage temperatures range from -30°C to +80°C.

Interface Pin Function

Pin No. Symbol Level Description
1 VOUT   DC/DC voltage converter. Connect a capacitor between this terminal and VIN when the built-in booster is used.
2 CAP1N   For voltage booster circuit(VDD-VSS)
External capacitor about 0.1u~4.7uf
3 CAP1P  
4 VDD 3.0/5.0V Power supply
6 SDA   (In I2C interface DB7 (SDA) is input data.
SDA and SCL must connect to I2C bus (I2C bus is to connect a resister between SDA/SCL and the power of I2C bus ).
7 SCL   (In I2C interface DB6 (SCL) is clock input.
SDA and SCL must connect to I2C bus (I2C bus is to connect a resister between SDA/SCL and the power of I2C bus ).
8 RST   RESET (Low active)
