STLED524 - Intelligent matrix LED display driver

General Description

The STLED524 is a 5x24 dot matrix LED display driver.

It can drive each dot with a current up to 20 mA.

Rows of the matrix are multiplexed.

Key Features

  • Operating input voltage range from 2.7 V to 5.5 V.
  • 5x24 LED matrix driver.
  • Adjustable luminance separately for each LED thanks to internal registers in 255 steps.
  • Internal registers store 2 patterns.
  • 4-way scroll function with the possibility to lock column data.
  • PWM dimming in 255 steps.
  • Adjustable blanking time.
  • Automatic slope function.
  • Cycle time and slope time adjustable for each dot separately.
  • SPI i.
