Note the following details of the code protection feature on Microchip devices:
•
Microchip products meet the specification contained in their particular Microchip Data Sheet.
•
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
•
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
•
Microchip is willing to work with the customer who is concerned about the integrity of their code.
•
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.

BOARD USER’S GUIDE
Chapter 1. Product Overview
1.1
INTRODUCTION
The EMC1182 Temperature Sensor Evaluation Board provides an easily accessible
platform to test the various features of the EMC1182. The System Management Bus
(SMBus) communication is accomplished using an Universal Serial Bus (USB) bridge,
providing a standard interface for the application code interface. The board is populated with a 3x3 DFN version of the EMC1182 device.
1.2
EMC1182 DEVICE FEATURES
The EMC1182 device is a two-channel SMBus temperature sensor featuring both
pin-selectable and fixed SMBus address capability. The communications bus is also
compatible with I2C communication protocol (see SMSC® application note AN 14.0
rev.1.1 - “SMSC Dedicated Slave Devices in I2C Systems” for details on the differences
between the SMSC SMBus implementation and standard I2C/SMBus).
One externally connected temperature diode and one internal diode are available for
temperature sensing. THERM and ALERT outputs have programmable temperature
limits.
1.3
WHAT IS THE EMC1182 TEMPERATURE SENSOR EVALUATION BOARD?
All functions of the EMC1182 device can be tested and observed using the USB-based
EMC1182 Temperature Sensor Evaluation Board. Figure 1-1 shows the block diagram

Chapter 3. Hardware Description
3.1
INTRODUCTION
The EMC1182 Temperature Sensor Evaluation Board provides the means to
demonstrate all of the EMC1182 features, and allows the registers to be viewed and
modified. LEDs indicating status information and test points are included to enable
system voltage monitoring, using a voltmeter or an oscilloscope.
3.1.1
Power Source
The board requires only one universal serial bus (USB) connection to power the board.
The USB-to-SMBus bridge regulates the +5V USB power to +3.3V used by the
EMC1182 and other evaluation board circuitry.
3.2
USB-TO-SMBUS BRIDGE
The USB-to-SMBus bridge is based on an 8-bit microcontroller with integrated USB
and SMBus interfaces, as well as internal flash and RAM. During the evaluation board
manufacturing process, the firmware is loaded into the bridge that provides the interface between the USB and the SMBus. Power is sourced to the microcontroller from
the USB interface for device power and communication.
3.2.1
Direct SMBus Connect Option
It is also possible to connect an external SMBus master to the EMC1182 Temperature
Sensor Evaluation Board. A few jumper settings are required to drive the EMC1182 on
the evaluation board, as explained in the following steps:
• Remove the jumpers on header JP10 and connect the SMBus master to the SDA,
SCL and ALERT pins (3, 5 and 7, respectively), as well as an external supply for
+3.3V (pin 1).
• Remove resistors R19, R20, R22 and R25, shown in Figure 3-1.
• The +3.3V can be supplied by the SMBus bridge by leaving the +3.3V jumper in
place and retaining the USB connection.
3.2.2
Supplemental 1.8V SMBus Pull-up
A 1.8V (nominal) linear regulator is placed on the board along with the jumpers to
connect SDA and SCL to a 1.8V pull-up supply. Once the jumper resistors are
disconnected, jumpers connecting J2-1 to J2-2 and J2-3 to J2-4 may be installed to
activate the 1.8V pull-ups. This jumper is identified in Figure 3-1 by the blue circle.

RESISTANCE ERROR CORRECTION (REC)
The external diode 1 (Q1) on the board has a series resistance adjustment on the DN
line. Checking the Resistance Error Correction (REC) feature is accomplished by
turning the resistor wheel R5. With the REC on, the temperature will not change as the
wheel is turned. With REC off, a significant temperature error will occur.
3.4
TEST POINTS
The EMC1182 Temperature Sensor Evaluation Board includes test points for the
following:
• ALERT output (TP1)
• THERM output (TP2)

REMOTE DIODES
The evaluation board is populated with jumpers to connect to the on-board diode or an
off-board diode (see Table 3-2).
To connect to an off-board CPU or GPU, remove both jumpers from header J1. Then
connect Pin 1 to the ‘remote+’ terminal of the off-board diode and Pin 2 to the ‘remote–’
terminal of the off-board diode. Make sure a common ground exists between the
off-board diode (GPU, etc.) and the evaluation board. Ensure that the off-board diode
is properly biased. Consult the CPU manufacturer’s data sheet for guidance on
interfacing to the thermal diode. Refer to the EMC1182 Temperature Sensor Evaluation
Board schematic in Appendix A. “Schematic and Layouts” for details on the
evaluation board header connections.

CHIP MANAGER APPLICATION OVERVIEW
The Chip Manager application enables the user to display temperature readings, set
temperature limits and read/write configuration register values. The Chip Manager
initially displays a Quick Help screen (see Figure 2-7). For detailed information on
application features and usage, select Help > Contents to display the HTML-based
Help document, as shown in Figure 4-1.

Real-Time Register Graphs
The Chip Manager software has the ability to plot register values in real-time, up to a
10 Hz continuous rate.

4.1.2
Selecting Registers to Plot
1. To plot a register, right-click the desired register name or value. Select the “Add
Register(s) to Plot” from the context menu (see Figure 4-2), to add the register
or value to the plot list.
FIGURE 4-2:
Adding Registers to Plot.
2. Once the desired register is added to be plotted, a graphic plot window will
appear with a legend on top, as shown in Figure 4-3. The two windows can be
rearranged independently.
FIGURE 4-3:

3. To plot additional registers, go back to the Chip Manager main window and
repeat Step 1.

4.1.3
Starting the Plots
All plots can be started simultaneously by selecting Control > Plots > Start All Plots from
the menu, in the main application window. Multiple plots will be in sync if they are
started simultaneously.
Individual plots may be paused at any time by clicking Control > Pause in the plot
window. This will not cause loss of captured data on the other plot windows.
For a better view on the plot, select a different “Time per division” value in the
drop-down menu at the bottom of the plotting window. This scale change affects both
the real-time mode and the playback mode, while the rate at which data is recorded is
unaffected.
4.1.4
Sampling a Plot
Figure 4-4 is an example of temperature history. Internal Temperature, External
Diode 1 Temperature and External Diode 1 High Limit are selected for plotting. The
results after the plot starting are that the External Diode Temperature High Limit is
reduced, the External diode 1 starts at room temperature and is then heated by simply
placing a finger on the external diode Q1.

Exporting and Importing the Plot Data
The data on each plot window may be stored in a semicolon-separated text file. To save
the data, follow the steps:
1. Stop the plotting by selecting Control > Stop from the plot window, or Control >
Plots > Stop All Plots from the Chip Manager main window.
2. Select File > Export from the plot window to save the data.
To review saved data:
1. Select File > Import from an open plot window and then select the file name to
open.
Note:
