Each driver can control up to 64 pixels or segments, and you can chain them to control more. They take SPI input to reliably produce a stable display. In addition, this driver natively understands LED matrices and segment displays so you don't have to make your life any harder than it already is by forcing you to map bits to pins.\u003c\/p\u003e\n\n\u003cp\u003eThe device includes an on chip BCD code-B decoder, a multiplex scan circuitry, segment and display drivers, and a 64 Bit (8 x 8) startic RAM memory to store each digit. The memory is used to store the LED settings, so that continuous reprogramming is not necessary. \u003cspan style=\"line-height: 1.6;\"\u003eEvery individual segment can be addressed and updated separately. Only one external resistor is required to set the current through the LED display. Brightness can be controlled either in an analog or digital way. The user can choose the internal code-B decoder to display numeric digits or to address each segment directly. \u003c\/span\u003e\u003cspan style=\"line-height: 20.7999992370605px;\"\u003eA convenient 4-wire serial interface connects to all common microprocessors and individual digits may be addressed and updated without rewriting the entire display.\u003c\/span\u003e\u003c\/p\u003e\n\n\u003cp\u003eThe \u003cspan style=\"line-height: 20.7999992370605px;\"\u003eMAX7219CNG+ \u003c\/span\u003efeatures an extremely low shutdown current of only 20µA and an operational current of less than 500µA.
