ZLG7289B 的主要特性

􀂄 很宽的工作电压范围：＋2.7～6V；

􀂄 直接驱动8 位共阴式数码管（1 英寸以下）或64 只独立的LED；

􀂄 能够管理多达64 只按键，自动消除抖动；

􀂄 段电流可达15mA 以上，字电流可达100mA；

􀂄 利用功率电路可以方便地驱动1 英寸以上的大型数码管；

􀂄 具有左移、右移、闪烁、消隐、段点亮等强大功能；

􀂄 要显示的数据提供有两种不同的译码方式（也可以选择不译码）；

􀂄 不接数码管而仅使用键盘管理功能时，工作电流可降至3mA；

􀂄 与微控制器之间采用SPI 串行总线接口，操作方便，占用I/O 资源少；

􀂄 工作温度范围：－40～＋85℃；

􀂄 封装：SOP-28，DIP-28。-ZLG7289B is guangzhou ZhouLiGong SCM development Co., LTD. To design digital tube display drivers and keyboard scan

Management chip, can direct drive a total of eight Yin type digital tube (or 64 only independent LED), also can scan management as many as

Only 64 buttons. ZLG7289B interior contains show decoder, can be directly accept BCD or hexadecimal yards, and also to provide

There are two kinds of decoding way. In addition, but also has a variety of control instruction, such as vanishing, flashing, moves left, move to the right, period of addressing, etc.

ZLG7289B using SPI serial bus and micro controller interface, occupies only a few root I/O mouth line. Use of selected signals,

More pieces of ZLG7289B can also be connected together with and use, convenient to achieve more than eight display or more than 64 only buttons

Application.

ZLG7289B can be widely used in instrumentation, industrial controller, bar displays, the control panel, etc.
