MAX6952 Evaluation Kit
General Description
Features
The MAX6952 evaluation kit (EV kit) is an assembled
and tested PC board that demonstrates the MAX6952
SPI™-interfaced four-digit 5 x 7 matrix LED display dri-
ver. Two cascaded MAX6952s are used to drive eight
5 x 7 monocolor matrix displays. The EV kit is powered
by a user-supplied 2.7VDC to 5.5VDC power supply.
The SPI-compatible serial interface is connected to an
IBM- compatible PC parallel port for easy evaluation.
The EV kit can be reconfigured for interfacing to a
user’s microcontroller for standalone operation.
