概述

Description

MAX7219ENG (MAX7219) is a compact LED display driver with a serial interface. It can drive up to 8 digits of 7‑segment LEDs or an 8×8 LED matrix, using 64 constant‑current LED sinks.
Key points:
- Interface: 3‑wire SPI‑like (DIN, CLK, CS) with 16‑bit frames (8‑bit address, 8‑bit data); supports daisy chaining.
- Outputs: 8 digits × 1 current sink per segment (A–G, DP), plus 8 digit drivers for multiplexing.
- Features: selectable brightness (intensity 0–15), decode mode for 0–9/A–F, display‑test, shutdown, and ISET pin to set LED current.
- Power: typical operation at 4.5–5.5V; current per LED is programmable.
- Applications: digital clocks, counters, scoreboards, LED matrices, where you want simple MCU control without many pins.
In short, MAX7219ENG simplifies driving multiple LED digits/matrices with a single cheap MCU interface and daisy‑chain scalability.

Package

It’s a 24-pin package (DIP-24 and SO-24 options available).

Pinout

Pin count: 24 pins (DIP-24 / SO-24).
Function: MAX7219ENG is a serially interfaced, constant-current LED display driver for up to 8 digits of 7-segment (64 LEDs). It uses an SPI-like interface (DIN, CLK, LOAD) with DOUT for daisy chaining. It provides 8 segment outputs (A–G and DP) and 8 digit drivers, with current set by an external ISET resistor. It enables multiplexed driving and includes V+ and GND pins.

Manufacturer

Manufacturer: Maxim Integrated (now part of Analog Devices). Maxim Integrated is a global semiconductor company that designs and manufactures analog, mixed-signal, and digital integrated circuits.

Application

- 7-segment LED displays (up to 8 digits) and 8×8 dot-matrix displays
- Digital clocks, timers, counters, scoreboards
- Signage and panel displays in consumer electronics
- Instrumentation and control panels
- Educational/hobby projects (Arduino, Raspberry Pi)
- Cascaded displays for larger digit counts (up to 64 digits)
