Chapter 2. Installation and Operation

2.1 INTRODUCTION

The MCP401XEV Evaluation Board allows the system designer to quickly evaluate the operation of the MCP40D18 10 kΩ (-103) Digital Potentiometer device using the PICkit Serial Analyzer. The PICkit Serial Analyzer is available separately (order number: DV164122).

The MCP401XEV Evaluation Board is a minimum configuration for the device. As well as the device, other desired passive components (resistors and capacitors) and connection posts may be installed.

The MCP401XEV Evaluation Board can also be very easily jumpered into a customers existing circuit. This gives an indication of the MCP40D18 device performance, but is affected by the jumper lead length and the EM noise that the jumpers pick up.

The MCP401XEV Evaluation board uses the generic SC70EV Evaluation Board PCB, and includes a second blank PCB. Additional PCB may be ordered (order number: SC70EV). The SC70EV kit includes 5 blank PCBs.

Other boards can be easily built up using the SC70EV PCB to allow evaluation of other resistance options (5 kΩ, 50 kΩ, or 100 kΩ) or any of the other devices in the following packages:

• SC70 package (uses I ^2 C interface)
- MCP4017, MCP4018, MCP4019, MCP40D17, or MCP40D19
- SOT-23 package (uses Up/Down interface)
- MCP4012, MCP4013, MCP4014, MCP4022, MCP4023, or MCP4024
• DIP-8 Package (uses SPI interface)
- MCP4131, MCP4141, MCP4151, or MCP4161

The MCP401XEV Evaluation Board also has a 6-pin interface (PICkit Serial, ICSP, etc.) whose signals can easily be jumpered to any of the device's pins.

Additional information on using the SC70EV Evaluation Board PCB or for modifying the MCP401XEV board is available in the SC70EV User's Guide (DS51874). Appendix A. "Schematic and Layouts" has information on the PCB schematic and layout while Figure 2-2 shows components that are installed on the PCB.

2.3 GETTING STARTED

The MCP401XEV Evaluation Board allows quick evaluation of the MCP40D18-103AE/LT device. This device is in the potentiometer configuration with terminal B internally tied to ground. This devices has an R_AB resistance that is typically 10 kΩ and has a slave I²C device address of 7Ch. Evaluation can be done by:

• Using the PICkit Serial Analyzer for interface communication
• Jumpering the MCP401XEV Evaluation Board into your application circuit to control the MCP40D18-103A device

This user guide will discuss the steps needed to evaluate the MCP40D18-103AE/LT device using the PICkit Serial Analyzer (order number: DV164122).

Section 2.5 “Configuring The PICkit Serial Analyzer” shows the steps to configure the PICkit Serial Analyzer as well as create User Script files which are used to communicate with the MCP40D18, based on the devices I²C communication protocol format.

2.4 MCP401XEV EVALUATION BOARD DESCRIPTION

The MCP401XEV Evaluation Board uses the flexible SC70EV Evaluation Board PCB. This simple Evaluation Board allows the system designer to quickly evaluate the operation of the MCP40D18-103A device ( R_AB(TYP) = 10 k and has a device slave I^2C address = 7Ch) using the PICkit Serial Analyzer or by jumpering the board into their application system. The PICkit Serial Analyzer is available separately (order number: DV164122).

2.4.1 The Hardware

Figure 2-2 shows the component layout of the MCP401XEV Evaluation Board. This is a small four-layer board (1.43" x 1.255" (36.322 mm x 31.877 mm)). There are ten connection points/pads that can use either through-hole or surface-mount connector posts.

The pad labeled VDD is connected to the PCB power plane, while the pad labeled VSS is connected to the PCB ground plane. All the passive components that are connected to VDD or VSS are connected to either the power plane or ground plane.

The eight remaining PCB pads correspond to the device pins (i.e.; pad 1 connects to pin 1).

Each pad has two passive components associated with them: a pull-up resistor and a pull-down resistor. The pull-up resistor is always RXU and the pull-down resistor is RXD. The "X" is a numeric value that corresponds to a particular pad (1 to 8). As an example, Pad 5's pull-up resistor is R5U. Capacitor C1 and C2 are the power supply filtering capacitors. For whichever pin is the device's VDD, the RxD component footprint can be used for the device's bypass capacitor. Table 2-2 describes the components.

A 6-pin header interface is available to support the PICkit Serial or the PICmicro In-Circuit Serial Programming (ICSP) interface.

Note 1: Whichever pin is the device's VDD pin, that corresponding RXD footprint can be used for the device's bypass capacitor. So if Pin 8 is the device's VDD pin, then install the bypass capacitor in the R8D footprint.
2: All passive components use the surface mount 805 footprint.

Note 1: Whichever pin is the device's VDD pin, that corresponding RXD footprint can be used for the device's bypass capacitor. So if Pin 8 is the device's VDD pin, then install the bypass capacitor in the R8D footprint.
2: All passive components use the surface mount 805 footprint.
3: If board is powered via the VDD and GND connection points, the use of bypass capacitors on C1 and C2 may improve performance. The benefit is reduced if the board is powered via the PICkit Serial interface.

Double clicking on the WriteAddrA8 Example I2CM Script will load the Script Details. Figure 2-9 shows what the values mean in the Script Details. These values are hex numbers.

The first value (03h), is the number of bytes that will be written. The second byte is the I²C Slave address (A8h) of the device with the Read/Write bit forced to '0' (an I²C write). The next two bytes (02h and 33h) are data bytes, and these values will be dependent on the slave I²C device protocol format and the desired operation.

Double clicking on the ReadAddrA8 Example I2CM Script will load the Script Details. Figure 2-10 shows what the values mean in the Script Details. These values are hex numbers.

The first value (02h) is the number of bytes that will be written. The second byte is the I²C Slave address (A8h) of the device with the Read/Write bit forced to '0' (an I²C write). The next byte (00h) is a data byte, and the value will be dependent on the slave I²C device protocol format and the desired operation.

Now a I ^2 C Restart bit is forced onto the I ^2 C bus. The next byte (01h) indicates how many bytes will be written. The next bit (A9h) is the I ^2 C Slave address (A8h) of the device with the Read/Write bit forced to '1' (an I ^2 C read). The last byte (10h) is the number of bytes that will be read from the I ^2 C Slave Device. The value will be dependent on the slave I ^2 C device protocol format and the desired operation.

To create the write script for the MCP40D18, double click on the WriteAddrA8 script in the "Example I2CM Scripts" column. This loads the script (see Figure 2-9) into the "Script Detail" column. Modify the script details so that it looks like Figure 2-11. Then, in the "Script Name" write the name that you would like to call the script. We chose "MCP40D18_Write" (see Figure 2-11).

Then click on the "Save Script" button. This will save the script, which can then be accessed under the "User I2CM Script" column (see Figure 2-11). This script will be available when the GUI is opened in the future (unless the script has been cleared or deleted).

Note: The saved User Scripts are saved to a text file. The file is saved in the PICkit Serial Analyzer directory. This User Scripts file is called: CommScripts.txt The default install location of the file is: C:\Program Files\Microchip\PICkit Serial Analyzer

2.6 MCP40D18EV DEMO STEPS

This demo assumes that you know how to configure the PICkit Serial Analyzer for Master I ^2 C operation. See Section 2.5 “Configuring The PICkit Serial Analyzer” or the PICkit Serial Analyzer User’s Guide (DS51647) for additional information.

1. Plug the PICkit Serial device into the PC's USB port.
2. Plug the MCP40D18EV board into the PICkit Serial.
3. Start the PICkit Serial GUI.
4. Ensure the GUI is in Master I ^2 C communication mode (see Figure 2-4).
5. Ensure that the Master I ^2 C configuration is appropriately configured (see Figure 2-6).
6. Measure the wiper voltage on the MCP40D18EV board using an oscilloscope or digital multimeter. Measure voltage from the ground plane (GND) to the Wiper (P7). The voltage on the wiper should be V_DD/2 (2.5V) .
7. Open the Script Builder window (see Figure 2-7).
8. Double click on the "WriteAddrA8" script in the "Example I2CM Scripts column. This loads the Script Detail column (see Figure 2-9).
9. Modify the "Script Detail" so that it is like that shown in Figure 2-13.
10. Click on the "Execute Script" button. This executes the script shown in the script detail column, which will update the wiper value to 7Fh. The Wiper voltage will now be V_DD ( 5V). The Transaction window (see Figure 2-15) will be updated to indicate the execution of the script.
11. Select the "MCP40D18_Read" script in the User I2CM Scripts column. It should look like Figure 2-14.
12. Click on the "Execute Script" button. This executes the script shown in the script detail column. The Transaction window (see Figure 2-15) will be updated to indicate the execution of the script. The Data read is shown in the last line.
13. Select the "MCP40D18_Write" script in the User I2CM Scripts column. It should look like Figure 2-13.
14. Modify the data value to write to the wiper (see Figure 2-13) to 1Fh.
15. Click on the "Execute Script" button. This executes the script shown in the script detail column, which will update the wiper value to 1Fh (from 7Fh). The Wiper voltage will now be 1/4^*V_DD ( 1.25V ). The Transaction window (see Figure 2-16) will be updated to indicate the execution of the script.
16. Select the "MCP40D18_Read" script in the User I2CM Scripts column. It should look like Figure 2-14.
17. Click on the "Execute Script" button. This executes the script shown in the script detail column. The Transaction window (see Figure 2-16) will be updated to indicate the execution of the script. The Data read is shown in the last line.
18. You can repeat the sequence of writing values to the wiper register or Writing then reading the values back.

NOTICE

If at any time during script execution, an error message is generated in the transaction window, it is good practice to reset the PICkit Serial Analyzer (PKSA). The PKSA can be reset using the "Reset" toolbar icon. Verify that subsequent script operations do not generate errors.
