MAX6901 Evaluation System/Evaluation Kit
Evaluates: MAX6901
General Description
The MAX6901 evaluation system (EV system) consists
of a MAX6901 evaluation kit (EV kit) and a companion
Maxim SMBus鈩?interface board.
The MAX6901 EV kit is an assembled and tested PC
board that demonstrates the MAX6901 3-wire serial
real-time clock (RTC). This EV kit is intended to demon-
strate the functionality and features of the MAX6901
RTC. It is not designed to exercise the MAX6901 at its
maximum serial 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
SPI鈩? 3-wire, and SMBus (2-wire) interfaces. Windows
廬
95/98-compatible software provides a user-friendly
interface to exercise the features of the MAX6901.
(Note: Windows NT/2000 requires additional driver soft-
ware; contact the factory.) The program is menu driven
and offers a graphic interface with control buttons and
status display.
Order the complete EV system (MAX6901EVSYS) for
comprehensive evaluation of the MAX6901 using a PC.
Order the EV kit (MAX6901EVKIT) if the MAXSMBus
module has already been purchased with a previous
Maxim EV system, or for custom use in other 碌C-based
systems.
