Chapter 1. Product Overview
1.1 INTRODUCTION
The MCP46XX PICtail™ Plus demonstrates the features and abilities Daughter Board
of Microchip’s MCP45XX and MCP46XX Digital Potentiometers. This board is
designed to exclusively use the MCP46XX devices.
The MCP45XX and MCP46XX are digital potentiometers with an I2C interface. These
devices have either 7 bits or 8 bits of resolution, single or dual offering, and are
available as either volatile or non-volatile memory options.
This board is designed to easily operate with any of the following:
Explorer 16 Development Board (DM240001)
PICkit™ Serial Analyzer (DV164122)
Other PICDEM Demo Board that includes a PICtail Plus female connector
The use of the Explorer 16 Development Board (DM240001) will require a tool to
program the supplied firmware into the PIC24FJ128GA010 device. The use of any
other PICDEM Demo Board will require the user to modify the supplied “C” source
program appropriately.
The use of the PICkit Serial Analyzer will require the PC GUI interface program to
control the command and data sent to the MCP42XX devices serial port. The PICkit
Serial Analyzer GUI may be used.
This chapter covers the following topics:
What is the MCP46XX PICtail™ Plus Daughter Board?
What the MCP46XX PICtail™ Plus Daughter Board Kit includes.

1.2 WHAT IS THE MCP46XX PICTAIL™ PLUS DAUGHTER BOARD?
The MCP46XX PICtail™ Plus Daughter Board is used to demonstrate the use of digital
potentiometers. This board is designed to be used in conjunction with either the
Explorer 16 Development Board or the PICkit™ Serial Analyzer. Figure 1-1 shows the
board’s components placement and the purpose of the jumpers.
The board has an MCP4261-103 (10 kΩ) device for evaluation. This device is in the
TSSOP package (U2). This is a dual 8-bit Non-Volatile Potentiometer device. The
MCP4661 uses an I2C interface and can be controlled via the PICkit Serial Analyzer
interface (J1) or via the PICtail Plus interface (J3).
When using the PICtail Plus interface, the HVC voltages can be taken to a VIHH level
for high voltage commands. This is done by controlling the selection of the analog
switch device (U1).
Jumpers allow the Terminal A and Terminal B voltages to be tied to AVDD and VSS, or
come from an external source.

Each digital potentiometers Terminal A pin can be individually connected to either
AVDD or the corresponding VAx pad
Each digital potentiometers Terminal B pin can be individually connected to either
AVSS or the corresponding VBx pad
It can control the voltage on the MCP4661’s HVC/A0 pin to either VSS, 3.3V, 5.0V,
or 9.0V via control signals from the PICtail Plus interface (J3)
It can control the MCP4661 via the PICkit™ Serial Analyzer interface (J2)
PIC24 can monitor the voltage levels of the MCP4661’s W0 and W1 pins
It is supplied with a “C” program that demonstrates normal and high voltage
commands
It demonstrates a split rail application, with digital logic at 3.3V and analog
operation at 5.0V

2.3.1 The Hardware
Figure 2-2 shows the component placement of the MCP46XX PICtail™ Plus Daughter
Board as well as the operation of the board jumpers.
The VAx and VBx pads allow an external voltage source to be applied to the device’s
desired Terminal A or Terminal B pin. The VWx pad is directly connected to the
corresponding Terminal W pin, which makes it easy to measure the resulting voltage.
The AVDD pad allows an external power supply to power the board, which should
improve performance compared to powering the board via the PICtail Plus header or
the PICkit Serial Analyzer.
The Printed Circuit Board (PCB) has been designed for the support of the SPI and I2C
device families (MCP42XX and MCP46XX), so not all components are installed to
support the operation of the SPI version of the MCP46XX PICtail™ Plus Daughter
Board.
2.3.1.1 JUMPER DESCRIPTIONS
Figure 2-2 shows the function of the MCP46XX PICtail™ Plus Daughter Board
jumpers. Some of the jumpers configure the voltage source of the Terminal A and
Terminal B pins while others determine the connection of the W pins. Lastly, there is a
jumper to ensure that drive conflicts do not occur if an external power supply is being
used for the AVDD voltage.
The default jumper configuration for the shipped MCP46XX PICtail™ Plus Daughter
Board is shown in Figure 2-3.

FIGURE 2-3: MCP46XX PICtail™ Plus Daughter Board Layout with Default Jumper Settings
2.3.2 The Firmware
The supplied PIC24FJ128A010 firmware is written in 'C' for the Microchip 'C' Compiler.
The program is written using Microchip's released I2C library routines.
There are two program modes of operation, determined by the state of the S3 switches
after a device reset. Program one will generate a saw wave on Wiper 1 pin (VW1), while
program two will allow the user to control the value of the Wiper 1 register with the S4
and S6 switches. If it is desired to save that setting, the S5 switch can be depressed to
copy the value in the Volatile Wiper 1 register to the Non-Volatile Wiper 1 register. So
on any POR/BOR event the volatile Wiper 1 register will be loaded with the value of the
non-volatile Wiper 1 register.
Note: This is the jumper configuration that the board should be shipped with.

2.4 MCP46XX PICTAIL™ PLUS DAUGHTER BOARD DEMOS
This section describes how to demonstrate the MCP46XX PICtail™ Plus Daughter
Board. The demos will either use an Explorer 16 Development Board or a PICkit Serial
Analyzer.
The demo using the Explorer 16 Development Board is discussed in
Section 2.4.1 “Demos with the Explorer 16 Development Board”, while the demo
using the PICkit Serial Analyzer is discussed in Section 2.4.2 “Demo with the PICkit
Serial Analyzer”.
2.4.1 Demos with the Explorer 16 Development Board
This demo will use the Explorer 16 Development Board. This board needs to be
programmed with the supplied firmware. This firmware can be downloaded from the
Microchip web site. It is a good practice to check the Microchip web site for updates to
the demo firmware.
The supplied firmware program has two modes of operation. In the first mode, the
program generates a saw wave on the VW1 pin (see Figure 2-6). The second mode is
to display the operation of High Voltage commands to Wiper 1 (see Figure 2-7). This is
where the CS signal is driven to 9V.
The program selected is determined after a reset (including the Power-on reset) by the
state of the S3 switch. The programs are:
Wiper 1 Saw Wave (Switch S3 not depressed)
Increment / Decrement with High Voltage Write to Non-Volatile Wiper 1 Register
(Switch S3 depressed)
Table 2-1 shows the required hardware to operate the demo.
TABLE 2-1: DEMO HARDWARE REQUIREMENTS
Note: Both demos require that the MCP46XXDM-PTPLS board jumper settings
are as shown in Figure 2-4.
Note: For information on how to use the MPLAB-IDE, ICD-2, or any other aspect
of the PIC Development tool platform, please refer to the appropriate
documentation.

3 4-Channel oscilloscope Note 2
Note 1: A development tool to program the Explorer 16 Development Board is required.
This development tool could be Microchip’s MPLAB ICD-2.
2: An oscilloscope with fewer channels can be used, but this will require that the
probes be moved between signals to verify the output states. A 2-channel
oscilloscope is the minimum requirement, but it is not recommended.
