Specifications of CMAXQUSB+

Lead Free Status / RoHS Status
Lead free / RoHS Compliant
The Maxim Command Module (CMAXQUSB) receives
commands from an IBM PC through the USB to create
an SPI™ or SMBus™/I
evaluation kits (EV kits) that make use of the
CMAXQUSB require custom software and can be
ordered together as an evaluation system (EV system).
Ordering information for EV systems is included in the
EV kit’s corresponding data sheet.
An EV system is an EV kit combined with an interface
board such as a CMAXQUSB and custom software.
Refer to the appropriate EV kit data sheet for quick start
and detailed operating instructions.
The use of the CMAXQUSB as a MAXQ2000 develop-
ment target is not supported. Rather, use the MAXQ2000
EV kit (available at www.maxim-ic.com/MAXQ2000-KIT)
for this purpose.
The CMAXQUSB has been tested on Windows
Second Edition, Windows 2000, and Windows XP
19-3838; Rev 2; 12/10
SPI is a trademark of Motorola, Inc.
SMBus is a trademark of Intel Corp.
Windows and Windows XP are registered trademarks of
Microsoft Corp.
