產品敘述

WO1602L 16x2 字元型COG LCD 顯示器,外觀尺寸為 62.8 x 23 mm, 檢視區域尺寸為51.5 x 12.23 mm。此系列產品使用 ST7032Ai IC 可支援介面為I2C。此系列COG顯示器模組的操作溫度為-20℃ to +70℃; 儲藏溫度為-30℃ to +80℃。此模組為COG結構,低成本方案,外形輕巧,低功耗,低供電等特點,適用於小型電子產品、手持產品等。因應部分IC交期長, 華凌開發WO1602L作為WO1602H替代選項型號。

產品規格

Pin功能定義

Pin No. 符號 說明
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
