The MAX7219CNG is a compact, serial input/output common-cathode display driver that can interface microprocessors to 7-segment numeric LED displays of up to 8 digits, bar-graph displays, or 64 individual LEDs. Included on-chip are a BCD code-B decoder, multiplex scan circuitry, segment and digit drivers, and an 8×8 static RAM that stores each digit. RoboticsBD
Communication with the MAX7219 is achieved through a convenient 4-wire serial interface (supports SPI). Individual digits may be addressed and updated without rewriting the entire display. Only one external resistor is required to set the segment current for all LEDs. RoboticsBD
The IC also includes a 150μA low-power shutdown mode, analog and digital brightness control, a scan limit register that allows the user to display from 1 to 8 digits, and a test mode that forces all LEDs on. Featured By RoboticsBD.
