TM1668是一种带键盘扫描接口的LED驱动控制专用电路,用于控制数码管的显示。通过将LED或数码管的两端连接到TM1668的两个管脚上,可以实现对数码管的控制。例如,当GRID为1时,通过控制SEG1-8来分别控制每个管脚,以达到显示特定数字或字符的目的。要让数码管全部亮,可以对地址0x00输入0xFF。TM1668还具有MCU数字接口、数据锁存器、LED高压驱动和键盘扫描等功能。它主要用于VCR、VCD、DVD和家庭影院等产品的显示屏驱动。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
