产品概述

The MAX7219EWG+ is a 8-digit serially interfaced LED Display Driver for LED matrix displays. The MAX7219 is 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. A convenient 4-wire serial interface connects to all common µPs. Individual digits may be addressed and updated without rewriting the entire display. The MAX7219 also allow the user to select code-B decoding or no-decode for each digit. The devices include a 150µA low-power shutdown mode, analogue 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.
