Datasheet
19-2180; Rev 0; 11/01
The MAX6951 evaluation kit (EV kit) is an assembled and
tested PC board that demonstrates the MAX6951 serially
interfaced eight-digit LED display driver IC. The EV kit is
powered by a user-supplied +4VDC to +6.5VDC power
supply. A configurable +3.3V or user-configurable low-
dropout (LDO) linear regulated power supply provides
power for the entire EV kit. An SPI™-compatible serial
interface is connected to an IBM PC-compatible com-
puter’s parallel port for easy evaluation. The EV kit can
easily be reconfigured for interfacing with a user-sup-
plied microcontroller (standalone operation).
Windows
friendly interface to demonstrate the various features of
the MAX6951 IC. The program is menu driven and
offers a graphic interface with control buttons. Windows
NT/2000 support is available; contact the factory for
details.
