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.”

Chapter 2. Installation and Operation

2.1 INTRODUCTION

This chapter discusses the setup and operation of the MCP3551 PICtail™ Demo Board.

The MCP3551 PICtail™ Demo Board is designed to demonstrate Microchip Technology’s MCP3551 22-Bit Delta-Sigma Analog-to-Digital Converter performance using the DataView software installed on a Personal Computer (PC). The demo board can be used with the MPLAB Development Programmer for developing demonstration/evaluation firmware.

This demo board is designed to evaluate the MCP3551 with minimum Printed Circuit Board (PCB) noise. The PCB layout practices low-noise design to reduce the signal noise as much as possible in order to demonstrate the 22-bit performance of the MCP3551.

2.2 FEATURES

The MCP3551 PICtail™ Demo Board has the following features:

• Three precision potentiometers for demonstrating the capabilities of the MCP3551

• USB interface for connecting to a PC

• On-board PIC18F4550 Microcontroller Unit (MCU) with USB for communication with DataView software

• DataView software with easy-to-read format and data logging

• Three headers/connectors for programming the PIC18F4550 MCU using any of the following (see schematic):

- PICkit™ 1 Flash Starter Kit

- PICkit™ 2 Development Programmer

- MPLAB

2.3 GETTING STARTED

The MCP3551 PICtail™ Demo Board is a fully functional, assembled and tested board for evaluation of the MCP3551 22-Bit Delta-Sigma ADC. The board is engineered to provide a virtually noise-free analog signal to the MCP3551, so that the capabilities of the device can be observed using a PC loaded with the DataView software.

The setup process is as follows:

1. Install the DataView software.

2. Since the board can be powered by USB power or with a 5V power supply, connect only the USB cable or the USB cable and

3. After applying power, the “Power” LED (D1) will illuminate and either D4 (externally-powered) or D7 (USB-powered) will illuminate.

4. The drivers will automatically install the first time the board is connected.

5. Run the DataView software.

2.4.2 Hardware Power

The board can be powered directly from the USB cable or self-powered. LEDs, D4 and D7, indicate how the board is powered.

To power the board via the USB, simply connect the USB cable. D7 will illuminate.

To self-power the board, connect a 5V power supply to the power terminals. D4 will illuminate.

2.4.3 The Analog Input

By default, the analog input is provided by a voltage divider circuit on VIN+, with VINshorted to ground via a 0Ω resistor. These components are initially soldered on the board for demonstration purposes only and are not required by a typical MCP3551 system. These components should be removed when evaluating a sensor through JPX.

2.4.4 Customizing the Analog Input

For demonstration purposes, the voltage on the inputs is fixed via a voltage divider on V

+. However, experimentation with different voltages on the inputs is made possible

by the two SMA connectors (J1 and J3) and/or the 4-pin header (J10).

There are several reference designators (Zn) which can be populated, as needed, to evaluate the MCP3551, external circuits, Z1, Z2 and Z3, are populated to create the voltage divider. These components will need to be removed to accommodate the custom circuit. All other Zn designators are unpopulated.

2.4.5 Reading the MCP3551 Output Using the DataView Software

The DataView software displays the digital output of the MCP3551 in a graphical format on Windows PC through the USB port, where it is converted to decimal and then plotted. The sample size of each window calculation (Histogram, Output and Auxiliary) can be configured through the Configuration dialog box. There are three different windows that display the data.

2.4.5.1 OUTPUT WINDOW

The Output window (Figure 2-2) shows the ADC output as a scope plot. The Y-axis can be configured LSB (default), PPM, percentage or volts (see Figure 2-5).

2.4.5.2 HISTOGRAM WINDOW

The Histogram window (Figure 2-3) shows the distribution over the selected sample size. Each bin of the histogram is always the equivalent of 1 LSB, showing the true output noise performance of the system with this quanta.

2.4.5.3 AUXILIARY DATA SCREEN

The Auxiliary Data window (Figure 2-4) displays calculated information, such as mean LSB, mean PPM, sample size and output noise RMS (PPM).

2.4.5.4 CONFIGURATION WINDOW

The Configuration window has three tabs for configuration and information.

The Scope Plot tab allows the Y-axis and the units to be changed. The X-axis is fixed. The defualt for the Y-axis is ‘Auto’ for the min/max and LSB for the units.

The A/D Device tab displays the ADC used (MCP3551) and is also where the sample rate for displaying the data is set. Please note that the minimum should be ~90 ms (see Section 2.4.6 “MCP3551 Sample Rate Demo” for more information).

The USB Device tab displays information about the board/device.

2.4.6 MCP3551 Sample Rate Demo

The Sample Rate demo uses a combination of polling and time to sample the input signal. When the Play button in the software is pressed, the PIC18F4550 samples the Ready state of the MCP3551 every 10 ms by lowering CS pin. If the device is ready (i.e., the conversion is complete), the data is clocked out. Otherwise, CS

Note: Once data is read out and CS is toggled for the first time, the device is

Since the conversion time of the MCP3551 is ~72 ms and the Ready state is sampled at ~10 ms intervals, the data is available to the PC approximately every 72 ms, ±10 ms. However, the USB host queries the board for data every 10 ms. This implies that the minimum sample rate for the software (see Section 2.4.5.4 “Configuration Window” for details on setting the sample rate) should be > 92 ms (or ~100 ms). If the DataView software is set to a shorter sample rate, data will be repeated and the software will not reflect the true operation of the device.

See the MCP3550/1/3 Data Sheet (DS21950) for more details on conversion time and Single Conversion mode.
