APPLICATION NOTE 980
Experimenting with the MAX6952 and MAX6953 SPI and IC LED
Display Drivers from a PC

Abstract: This application note describes a PC program, downloadable free, to assist design, evaluation, font
design with MAX6952 and MAX6953 5x7 matrix LED display drivers.


The MAX6952 and MAX6953 are 4-digit common-row 5x7 matrix LED display drivers that are controlled through
a high speed SPI (MAX6952) or IC (MAX6953) serial interface. This application note describes a utility
program which allows a MAX6952 or MAX6953 driver to be controlled from a PC. The utility can be used
standalone simply to help an engineer familiarize himself
