It includes a piece of type B BCD coder, multiplexing scanning circuit, drive period of word, but also a 8 * 8 static RAM is used to store each data. Only an external registers used to set the period of current of each LED. A convenient four wire serial interface can join all general microprocessor. Each data can be addressed in the update does not need to rewrite all the display. MAX7219 also allows users to each data selection code or code. The device contains A 150 mu A low-power shutdown mode, analog and digital brightness control, A scan limit register allows the user to display 1-8 bits of data, there is also A let all LED detection mode.
