The MAX7219 is an integrated serial input / output common-cathode display driver. It can be connected to an 8-digit 7-segment digital LED display can also be connected to the bar graph display or 64 separate LED with the help of a microcontroller. The B BCD encoder includes an on-chip, multi-channel scanning loop word drive and also an 8 x 8 static RAM is used to store each data. An external register is used to set the current of each LED segment.
