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.”

Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.

Information contained in this publication regarding device applications and the like is provided only for your convenience and may be superseded by updates. It is your responsibility to ensure that your application meets with your specifications.

Product Overview

2.7 PIC32MZ EF CURIOSITY DEVELOPMENT BOARD (DM320104) OVERVIEW

Note 1: The PIC32MZ EF Curiosity Development Board is used for data capture

from the MCP331X1D Evaluation Board. This board can be purchased with preprogrammed SAR ADC firmware compatible with the MCP331X1D Evaluation Board (ADM00873).

2: The PIC32MZ EF Curiosity Development Board included in the

MCP331X1D Evaluation Kit is already preprogrammed with SAR ADC firmware.

The PIC32MZ EF Curiosity Development Board (DM320104) is a fully-integrated, 32-bit development platform featuring the high-performance PIC32MZ EF Series PIC Microcontroller (PIC32MZ2048EFM100), which is utilized for capturing the digital data received from the MCP331X1D Analog-to-Digital Converter (ADC) Evaluation Board.

Figure 2-1 shows the connection of the PIC32MZ EF Curiosity Development Board

directly between the MCP331X1D 16/14/12-Bit, 1 Msps SAR ADC Evaluation Board and the SAR ADC Utility Software.

The Curiosity Development Board (DM320104) connects to the PC through a USB cable, providing the user with two functionalities:

• The ability to send user commands directly to the device from the SAR ADC Utility Software.

• The ability to collect data from the evaluation board and send them to the SAR ADC Utility Software.

Figure 2-3 displays a close-up of the PIC32MZ EF Curiosity Development Board. More

information, including user’s guides and other resources for the Curiosity Development Board, can be found by visiting www.microchip.com.
