Fan Speed Control with the EMC2102 Device
Revision 0.2 (09-17-07)
USER MANUAL SMSC EMC2102
6
1 Overview
SMSC has introduced a series of Environmental Monitoring and Control (EMC) devices with integrated
fan control. This fan controller family devices feature the advanced closed-loop fan control technology
developed by SMSC’s engineering team.
This user manual provides detailed information about fan control features supported by one of those
EMC devices -- EMC2102, with detailed hand-on experiments for configuring the devices in real
applications.
2 Audience
This user manual assumes that the reader is familiar with the functionality of the EMC2102 device and
its evaluation board. The goal of the user manual is to help users to evaluate the new EMC device
using Chip Manager (ChipMan) software provided by SMSC. This user manual also can be used as a
reference material for other EMC devices which have fan control features.

4 The Evaluation System
The evaluation system used for this user manual has two major parts, as shown in Figure 4.1,
"EMC2102 Fan Control Evaluation System":
An EMC2102 evaluation board (EVB-EMC2102) with on-board 5V DC fan (Figure 4.2)
A PC with SMSC ChipMan software installed (requiring XML file for EMC2102 device)
This user manual contains several groups of user experiments which cover most of the fan control
features of the EMC2102 fan controller device. All examples are based on the 2102 device evaluation
board (EVB-EMC2102) and its software, but the methods and the results will apply to other EMC2102
applications.
