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 8x8 static RAM that
stores each digit.
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.
The IC also includes a 150A low-power shutdown mode, analog and
digital brightness control, a scanlimit register that allows the user
to display from 1 to 8 digits, and a test mode that forces all LEDs
This device comes in a 24-pin DIP package.
