MAX7219EWG

Description

8-digit 7-segment / 64-LED display driver, SPI, wide SOIC-24 — Maxim's classic LED matrix controller.

The MAX7219 is a compact, serial input/output common-cathode display drivers that interface microprocessors (μPs) 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. Only one external resistor is required to set the segment current for all LEDs.
