Chapter 1. Product Overview

1.1 INTRODUCTION

This chapter provides an overview of the MCP9984 Evaluation Board and covers the following topics:

• MCP9984 Device Short Overview
• What is the MCP9984 Evaluation Board?
• MCP9984 Evaluation Board Kit Contents

1.2 MCP9984 DEVICE SHORT OVERVIEW

The MCP9984 Evaluation Board is used to evaluate the MCP998X family of remote diode temperature monitors. Users can now easily evaluate many of the integrated features of the MCP998X device family. The MCP9984 Evaluation Board has the MCP9984-A, which has the SMBus address decode capability. The MCP9984 Evaluation Board also has on-board connectors to allow for diode-connected transistors used for off-board temperature measurements.

In addition, the MCP9984 Evaluation Board connects to the PC through a USB interface. Temperature can be data-logged using the Microchip Thermal Management Software Graphical User Interface (GUI).

1.3 WHAT IS THE MCP9984 EVALUATION BOARD?

The MCP9984 Evaluation Board enables users to easily evaluate many custom programmable features such as Temperature Alert Limit settings, Temperature Conversion Rate, Resistance Error Correction (REC) and Power Modes.

Figure 1-1 shows the top and bottom views of the MCP9984 Evaluation Board.

• (2) 2N3904TA transistor (TO-92 package).

Chapter 2. Installation and Operation

2.1 GETTING STARTED

This chapter describes how to power-up and interface with the MCP9984 Evaluation Board device. Items discussed in this chapter include:

• System and Configuration Requirements
• MCP9984 Evaluation Board Setup
- Software Setup

2.2 SYSTEM AND CONFIGURATION REQUIREMENTS

The MCP9984 Evaluation Board is designed to be used with a personal computer (desktop or laptop) running Microsoft ^® Windows ^® XP or later. For USB connectivity, the minimal physical requirement for the PC is a standard type-A USB 2.0 port.

2.3 MCP9984 EVALUATION BOARD SETUP

Before the MCP9984 Evaluation Board can be used, a few steps must be performed to install the PC software and configure the MCP9984 Evaluation Board's hardware.

1. Download the support material (PC application) that can be found on the EV23P16A board page, at www.microchip.com. Unzip the archive and install the executable.
2. When evaluating the MCP9984, ensure a jumper is populated at J5 to select the address decode resistance. Use Table 2-1 as a reference.

TABLE 2-1: MCP9984 ADDRESS DECODE

Resistance Selected at J5 SMBus Address

Chapter 3. Software GUI Description

3.1 THERMAL MANAGEMENT UTILITY - [MCP9984] SOFTWARE GUI OVERVIEW

The Microchip Thermal Management Software GUI allows users to evaluate the MCP9984 for temperature sensing applications. Once the hardware is connected, the software recognizes the board ID and displays the corresponding GUI for the MCP9984 Evaluation Board. Disconnecting the USB closes the GUI. This tool enables users to evaluate the sensor features and perform temperature data-logging.

Figure 3-1 depicts the Thermal Managemen Utility - [MCP9984] GUI.

As displayed in Figure 3-1, the GUI can be divided into three sections as follows:

1. Real-Time Acquisition action buttons
2. Temperatures, Sensor Settings and Registers List tabs
3. Data Acquisition Charting area

The features and functionality of the GUI are described below.

3.2 REAL-TIME ACQUISITION ACTION BUTTONS

The Play, Pause and Reset icons (Figure 3-2) can be used to perform continuous data acquisitions.

To stop the data logging click the Stop Recording button. Users can now go to the file's location to view the file.

Clicking the Update Registers button updates the GUI with all the registers of the selected device (see the Registers List tab for all register values).

3.3 TEMPERATURES, SENSOR SETTINGS AND REGISTERS LIST TABS

3.3.1 Temperatures Tab

The Temperatures tab displayed in Figure 3-4 shows the results of the MCP9984 temperature channels. This tab also displays the results of the various user programmable features of the MCP9984 Evaluation Board, such as the temperature ALERT and THERM status, Diode Fault status and hottest diode comparison.

3.3.2 Sensor Settings Tab

The Sensor Settings tab is divided into two sections:

• General Settings
• Beta & Ideality

3.3.2.1 GENERAL SETTINGS

Figure 3-5 displays the General Settings section under the Sensor Settings tab. This is where the user configures various features of the device.

Refer to the MCP998X data sheet for detailed information on the operation of these features and settings.

3.3.2.1.1 Standby Mode (One Shot)

Selecting Standby in the Active Mode drop-down menu puts the selected device in Standby mode. While in this mode, the device does not continuously acquire new data acquisitions. Instead, the device only acquires data when a One Shot command is issued. This is done by clicking on the One Shot button in the Real-Time Acquisition Action Buttons bar.

3.3.2.2 BETA & IDEALITY

Figure 3-6 displays the Beta and Ideality tab under the Sensor Settings tab. In this section, the user can manage the Auto-Beta Detection feature and ideality factor of the selected device. The Beta Value, which is determined by the device, is read-only. The ideality factor can be changed by the user.

3.3.3 Registers List Tab

The Registers List tab (Figure 3-7) contains a read/write table that contains all the user registers.

3.3.3.1 READING AND WRITING TO REGISTERS

Read

To read all registers, simply click the Update Registers button at the top of the GUI. To read an individual register, highlight the row of the register that you want to read, right-click, then select read.

Write

To write to a register, enter the value you wish to write to the corresponding Data High or Data Low cell. Then, click out of the cell and highlight the entire row, including the cell that was just written to. Then, right-click and select write. If the cell that is being written to is not highlighted blue with the rest of the row, the write function does not take place.

The logging interval can be adjusted using the interval scroll bar from 100 ms to 30s, as shown in Figure 3-8.

The data acquisition charting area (Figure 3-8) can be customized by double clicking the chart. Performing this action opens the Data Acquisition Customization window, shown in Figure 3-9.

Users can also zoom into a specific plot range by clicking and dragging the section. The data in the chart can also be exported by right-clicking the plot and selecting the Export dialog button.

3.4.0.1 DATA ACQUISITION CUSTOMIZATION WINDOW DESCRIPTION

The Data Acquisition Customization window contains eight tabs with several options allowing users to customize the data acquisition charting area.

The General tab (Figure 3-9) determines how the data acquisition charting area is displayed. General options include the border style, viewing style, font size, numeric precision and grid lines.

The Display option determines how the data acquisition charting area is generated: a graph, a table, or both.

The Plot tab, displayed in Figure 3-10, allows users to customize the appearance of the data sensor plots.
