产品叙述
WO1602L 16x2 字元型COG LCD 显示器,外观尺寸为 62.8 x 23 mm, 检视区域尺寸为51.5 x 12.23 mm。此系列产品使用 ST7032Ai IC 可支援介面为I2C。此系列COG显示器模组的操作温度为-20℃ to +70℃; 储藏温度为-30℃ to +80℃。此模组为COG结构,低成本方案,外形轻巧,低功耗,低供电等特点,适用于小型电子产品、手持产品等。因应部分IC交期长, 华凌开发WO1602L作为WO1602H替代选项型号。

Pin功能定义
Pin No. | 符号 | 说明 |
---|---|---|
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 |
