ZLG7290B 是广州周立功单片机发展有限公司自行设计的数码管显示驱动及键盘扫描 管理芯片。能够直接驱动8 位共阴式数码管（或64 只独立的LED），同时还可以扫描管理 多达64 只按键。其中有8 只按键还可以作为功能键使用，就像电脑键盘上的Ctrl、Shift、 Alt 键一样。另外ZLG7290B 内部还设置有连击计数器，能够使某键按下后不松手而连续有 效。采用I2C 总线方式，与微控制器的接口仅需两根信号线。该芯片为工业级芯片，抗干扰 能力强，在工业测控中已有大量应用。-Canton weeks ZLG7290B is Ligong Singlechip Development Co., Ltd. to design the digital tube display driver and the keyboard scan management chip. Can directly drive a total of 8 vaginal digital tube (or 64 independent LED), at the same time management can also scan up to 64 keys. Which has 8 buttons can also be used as function keys, like the computer keyboard on the Ctrl, Shift, Alt keys like. Another internal ZLG7290B batter has also set up counters, can press a button and a row after不松手effective. Using I2C bus mode microcontroller interface with only two signal lines. The chip-on-chip for industry, anti-interference ability, in the industrial measurement and control has been a large number of applications.
