推荐两颗料 LED显示驱动芯片 AT7219/7221可完全替代：MAX7219 MAX7211
商品详情
简介：
AT7219 / AT7221 是一种集成化的串行输入/输出共阴极显示驱动器，它连接微处理器与8位数字的7段数字LED显示，也可以连接条线图显示器或64个独立的LED。芯片包括片上BCD译码器，多路扫描回路，段，字驱动器，8 * 8的静态RAM用来存储每一个数据。通过外部电阻设置LED的段电流.AT7221与SPI? ，QSPI? 以及MICROWIRE? 相兼容，并且通过限制驱动电流变化斜率来减小电磁干扰。
芯片包含150uA 的低功耗模式，模拟和数字亮度调节控制，扫描限制寄存器容许用户显示1-8 位数据，测试模式可以让所有的LED 发光。
