evaluated, the Update_ Pot_ A_ and_ B checkbox is

enabled/disabled. The EV kit enters the normal operat-

ing mode when the USB connection is detected and the

part has been selected. Since the MAX5386M does not

have read capability, all the edit boxes are set to ques-

tion marks (??) and the Potentiometerꢀ track bar is set

to mid scale. If the USB connection is not detected, the

software prompts the user to retry, exit the program, or

enter the demo mode.

testing.

See the Detailed Description of Software section for more

information on the software features.

Detailed Description of Software

Graphical User Interface (GUI) Panel

The MAX5386M EV kit software GUI shown in Figure 1 is

a Windows program that provides a convenient means

to control the MAX5386M dual potentiometer. Use the

mouse or press the Tab key to navigate through the GUI

controls. The correct SPI write operations are generated

to update the MAX5386M internal memory registers

when any of these controls are executed.

Demo Mode

The EV kit software enters the demo mode, when the

USB connection is not detected, by selecting Cancel on

the MAX5386M_Evaluation_Kit_Interface_Circuit popup

window (Figure 2). The software can also enter demo

mode at any time from the main window by selecting

the Options_|_Demo_Mode menu item. When in demo

mode, all software communication to the EV kit circuit

is disabled; however, most of the software GUI is func-

tional. Demo mode allows the user to evaluate the soft-

ware without hardware connectivity. To exit demo mode,

deselect the Options_|_Demo_Mode menu item.

The software divides the EV kit functions into group

boxes. The Interface group box indicates the EV kit

Status and the last write operation Command_ Sent

and Data_ Sent indicators. This data confirms proper

device operation. The Device_ Connected combo box

selects the Maxim part being evaluated and enables

the Update_ Pot_ A_ and_ B checkbox function when

choosing the MAX5391 or MAX5393 option from the

list. The Default button programs both potentiometers

to their midscale positions. The lower Potentiometer_A

and Potentiometer_B group boxes provide controls to

change the respective wiper positions. The main win-

dow’s bottom-left status bar provides the USB interface

circuit communication status.

Potentiometer A and B Wiper Positions

The wiper position track bars (WA, WB) in the

Potentiometer_ A and Potentiometer_ B group boxes

are used to change the wiper position between the H_

and L_ end points. Use the computer mouse or arrow

keys to move the wiper position_between the 256 posi-

tion points. The wiper position can also be changed by

entering the desired integer value in the edit boxes, or

by pressing the up or down arrows in the respective

edit box. A change in the Wꢀ wiper position_track bars,

or HWꢀ/WLꢀ edit boxes writes to the registers and the

wiper position is updated with the data sent. The wiper

position is shown in the HWꢀ and WLꢀ edit boxes. The

HWꢀ edit box shows the wiper position with respect to

the potentiometer H end point and the WLꢀ edit box

shows the wiper position with respect to the potentiom-

eter L _ end point.

The EV kit software can also be used to evaluate

the MAX5386L, MAX5386N, MAX5388, MAX5391, and

MAX5393.

Software Startup

Upon startup, the EV kit software automatically search-

es for the USB interface board’s circuit connection.

In the Interface group box, the Device_ Connected

combo box allows the user to select the proper part

being evaluated. Upon selection of the device being

Factory Default

Simple SPI Commands

Pressing the Default button resets potentiometer A and

B wiper positions in the MAX5386M to the factory-default

midscale position.

There are two methods for communicating with the EV

kit, through the normal user-interface panel (Figure 1)

or through the SPI commands available by selecting

the 3-Wire_Interface (Figure 3) utility from the main pro-

gram’s Options_|_Advanced_Users Interface menu bar.

A window is displayed that allows SPI send/receive data

operations.

Status Indicator

The Status indicator in the Interface group box displays

EV_Kit_Operational when the EV kit enters the normal

operating mode after the USB connection is detected.

If the USB connection is not detected, or when the

software enters the demo mode, the Status indicator

displays Demo_Mode. Demo mode is used to exercise

the software without hardware connectivity.

On the 3-wire_interface tab, the Connection group box

defines the hardware connections of the interface. For

the EV kit, K10 is selected from the Clock_(SCK)(SCLK)

drop-down list, K12 from the Data_from_master_to_slave_

(MOSI)(DIN) drop-down list is disabled, K11 from the

Data_from_slave_to_master_(MISO)(DOUT) drop-down

list, K9 from the Chip-select_ (CS)_ for_ data_ framing

drop-down list, and Use_ standard_ connections_ for_

high-speed_SPI checkbox is checked (see Figure 3).

Command Sent Indicator

The Command_ Sent indicator in the Interface group

box displays the last command sent from the master

(software) to the MAX5386M. There are two commands

available in the MAX5386M IC. Table 2 describes the two

MAX5386M commands.

The Configuration group box allows the user to config-

ure the logic level and data rate. For the EV kit, check

the Send_&_Receive_MSB_first checkbox and verify that

the CPOL=1(clock_idle_high) and CPHA=1(sample_2nd_

edge)_checkboxes are unchecked (see Figure 3).

Data Sent Indicator

The Data_Sent indicator displays the last data sent from

the masters to potentiometer A (0x00) or potentiometer

B (0x01) registers.

The Send_and_Receive_Data group box allows the user

to send data to the MAX5386M. The Data_bytes_to_be_

written_edit box indicates data to be sent from the mas-

ter (microcontroller) to the device (MAX5386M). Eight-

bit hexadecimal numbers should be comma delimited.

Press the Send_Now button to transmit the data from the

master to the device. Data appearing in the Data_bytes_

received edit box is data read from the device. The Data_

bytes_ received edit box in the EV kit software always

shows a default value of 0xFF since the MAX5386M

does not send data back to the master.

The MAX5386M IC uses an 8-bit (MSBs, D7–D0) data

byte to set the wiper position. Refer to the MAX5386 IC

data sheet for additional information.

Keyboard Navigation

Press the Tab key to select each GUI control. The select-

ed control is indicated by a dotted outline. Using Shift

+ Tab moves the selection to the previously selected

control. Buttons respond to the keyboard’s space bar

and some controls respond to the keyboard’s up and

down arrow keys. Activate the program’s menu bar by

pressing the F10 key and then pressing the letter of the

desired menu item. Most menu items have one letter

underlined, indicating their shortcut key.

Note: The SPI dialog boxes accept numeric data in

hexadecimal format. Hexadecimal numbers must be pre-

fixed by $ or 0x. Figure 3 shows a simple SPI write-byte

operation using the included 3-wire interface diagnostics

tool. In this example, the software is sending command

0x00 (write to potentiometer A) and data 0x7F. The data

sequence sets the MAX5386M wiper position to 127.

When a number is entered into the edit boxes, it can be

sent to the device by pressing the Enter key. It is also

sent when Tab or Shift + Tab is pressed.

Detailed Description of Hardware

The MAX5386M evaluation kit (EV kit) is an assembled

and tested PCB that features the MAX5386M dual 50kI

digital potentiometers. Both potentiometer A and B have

an end-to-end resistance of 50kI and each wiper can be

programmed independently among 256 tap positions.

The EV kit uses a MAX5386M IC in a 16-pin thin QFN

package on a proven two-layer PCB design.

• Is the USB cable connected to the MINIQUSB+ board?

• Has Windows plug-and-play detected the board?

Bring up Control_Panel->System->Device_Manager,

and look at what device nodes are indicated for USB.

If there is an Unknown_ device_ node attached to

the USB, uninstall it—this forces plug-and-play to try

again.

The EV kit provides connector J1 to interface with the

MAX5386M CS, DIN, SCLK, and GND signals directly

to a user-supplied 3-wire system. Connector J1 also

provides a connection for the MAX5386M EV kit’s 2.6V

to 5.5V VPOWER power-supply input.

• If using an off-board SPI interface, is the power ground

connected to the EV kit ground (GND) at one of the

header J1 pin connections (J1-2, J1-4, J1-6, or J1-8)?

The EV kit is typically used with a MINIQUSB+ interface

board for communicating with a PC through the 3-wire

serial interface. Logic-level translators U7 and U8 pro-

vide proper SPI interface translation when using 2.6V to

5.5V to power the MAX5386M VDD input.

Table 4 for proper jumper JU1configuration.

MAX5386M VDD Input Configuration

Jumper JU2 selects the power source for the MAX5386M

VDD input. Install a shunt across pins 1-2 of jumper JU7

to operate the MAX5386M VDD input power using LDO

U5 output. Install a shunt across pins 2-3 to operate the

MAX5386M VDD input from the VPOWER rail. See Table

5 for proper jumper configuration for the MAX5386M

VDD power-supply input.

Regulator U5 has an adjustable output that can be con-

figured to a different voltage by replacing resistor R1.

tion for setting VPOWER rail.

SPI Clock, Data-, and Chip-Select Inputs

The MAX5386M features clock, data-, and chip-select

input pins for SPI-compatible communication to control

the MAX5386M wiper position. The clock, data-, and

chip-select pins can be driven by the MINIQUSB+ inter-

face circuit or the PCB header (J1), along with a user-

supplied external SPI-compatible controller. An external

SPI-compatible controller can be connected to CS

(J1-3), DIN (J1-5), SCLK (J1-7), and GND (J1-2, J1-4,

J1-6, J1-8) on header J1 to communicate with the

MAX5386M IC. When using an external SPI-compatible

controller, verify that the MINIQUSB+ interface board

has been disconnected from the EV kit’s J2 and J3 head-

ers. See Table 6 for header J1 pin assignment.

Alternatively, the EV kit’s VDD PCB pad can be used to

supply an external 2.6V to 5.25V to the circuit’s VPOWER

rail, by removing the shunt at jumper JU20.

MAX5386M Evaluation System

Potentiometer, Voltage-Divider, or

Note that to test the device in resistor mode, the ohmme-

ter must be GND referenced to the MAX5386M. This can

be accomplished by connecting the L_ pin to GND or

the H_ pin to U1 VDD. Resistance can then be measured

between W_ and L_ or W_ and H_ PCB pads.

Variable Resistor with Ground Reference

The EV kit provides an option to configure the MAX5386M

as a potentiometer or voltage-divider, open end, or

with ground reference, respectively. Use jumpers

JU3 and JU4 for potentiometer A, and jumpers JU5 and

JU6 for potentiometer B configurations. Tables 7 and 8 list

jumper options for configuring potentiometers A and B.

Evaluating the MAX5388, MAX5391,

and MAX5393 ICs

The EV kit is populated with additional PCB footprints

and various jumpers to evaluate the MAX5391 (U2),

MAX5393 (U3), and MAX5388 (U4), respectively.

The MAX5386M IC can also be configured as a variable

resistor by shorting the H_ and W_ pads together using

a wire. When operating as a variable resistor, any power

source connected to the H_, W_, or L_ pads must be

voltage and current limited to the maximum conditions

stated in the MAX5386 IC data sheet.

Refer to the MAX5388, MAX5391L, or MAX5393 EV sys-

tem data sheets for additional information when evaluating

the_MAX5388, MAX5391, or MAX5393 digital potentiom-

eters.
