MAX6902 Evaluation System/Evaluation Kit
General Description
The MAX6902 evaluation system (EV system) consists
of a MAX6902 evaluation kit (EV kit) and a companion
Maxim SMBus鈩?interface board.
The MAX6902 EV kit is an assembled and tested PC
board that demonstrates the MAX6902 SPI鈩?bus real-
time clock (RTC). This EV kit is intended to demonstrate
the functionality and features of the MAX6902 RTC. It is
not designed to exercise the MAX6902 at its maximum
SPI bus interface speed. A typical bus interface speed
is in the 90kHz range and depends upon the operating
system and computer used.
The Maxim SMBus interface board (MAXSMbus) allows
an IBM-compatible PC to use its parallel port to emulate
the SPI, 3-wire, and SMBus (2-wire) interfaces.
Windows 95/98
廬
-compatible software provides a user-
friendly interface to exercise the features of the
MAX6902. (Note: Windows NT/2000 requires additional
driver software; contact factory.) The program is menu
driven and offers a graphic interface with control but-
tons and status display.
Order the complete EV system (MAX6902EVSYS) for
comprehensive evaluation of the MAX6902 using a PC.
Order the EV kit (MAX6902EVKIT) if the MAXSMbus
module has already been purchased with a previous
Maxim EV system, or for custom use in other 碌C-based
systems.
