概述

CS1694 是一种动态 LED 控制/驱动器具有多种显示模式 6

×11 或 7×10

内部具有

8 级亮度

控制带有按键扫描功能可以扫描

10

×2 的键盘矩阵电路内部含有一个 14×8 的显示 RAM 以及

一个

5

×6 的按键数据 RAM 作为 MCU 的理想外围元件带有可以直接和 MCU 相接的串行口 Din

& Dout Stb Clk

CS1694 是在 CS1684 的基础上封装改动形成的在 CS1684 电路基础上将 Din 与 Dout 键合在

一起

Key3 和 Seg11 不键合其他功能与 CS1684 相同

该电路主要用作动态

LED 控制/驱动器也有按键扫描的用途是单片机与动态 LED 屏之间的

理想元器件

可以用在

DVD VCD 功放等整机上
