The MAX7219 is an integrated serial I/O common cathode display driver that connects a microprocessor with an 8-digit, 7-segment digital LED display, as well as a bar graph display or 64 independent LEDs. It includes an on-chip B-type BCD encoder, multiple scan loops, segment word drivers, and 8*8 static RAM to store each piece of data. There is only one external register used to set the segment current for each LED. A convenient four-wire serial interface connects all common microprocessors. Each data can be addressed during the update without overwriting all the displays. The MAX7219 also allows the user to choose whether or not to encode each piece of data. The entire device contains a 150 uA low power shutdown mode, controls analog and digital brightness controls, a scan limit register that allows the user to view 1 to 8 bits of data, and a detection mode that turns on all LEDs.
Only 3 IO ports are needed to drive 1 dot matrix! Flicker-free dot matrix display! Cascading is
