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

MCP3911 ADC EVALUATION BOARD
FOR 16-BIT MCUs USER’S GUIDE
Chapter 1. Hardware Description
1.1
OVERVIEW
The MCP3911 ADC Evaluation Board for 16-Bit MCUs system provides the opportunity
to evaluate the performance of the MCP3911 dual-channel ADC. It also provides a
development platform for 16-bit PIC®-based applications, using existing 100-pin PIC
microcontroller Plug-in Module (PIM) systems that are compatible with the Explorer 16
and other high pin count PIC®-based demo boards. The system comes with a
programmed PIC24FJ256GA110 PIM module that communicates with the Energy
Management Utility software for data exchange and ADC setup.
1.1.1
Feature Highlights
• Dual ADC MCP3911 output display using serial communication to the PC
software interface
• Simultaneous 55 ksps at OSR32 address loop ALL or 95 dB SINAD at OSR512
performance on MCP3911
• System and ADC performance analysis through graphical PC tools showing noise
histogram, frequency domain (FFT), time domain scope plot, and statistical
numerical analysis
• Robust hardware design with analog grounding and analog/digital separation,
allowing low noise evaluation of MCP3911 devices; includes separate power
supplies and power planes on a 4-layer board.
• PICtail™ Plus connectors for Explorer 16 daughter board compatibility

MCP3911
Digital Connection Overview PIM/MCP3911 Connections.
Ports A, B, and D are used for signals such as push buttons, output LEDs, CS and
MCLR (for MCP3911 data mode setting). Output Capture 1 is used for clock generation
in the MCP3911. Serial communication is achieved through the MSSP module 1.
The MCP3911 device is an ADC with a second order modulator and a third order sinc
filter, plus a first order sinc filter used for higher OSR’s values. This Delta-Sigma A/D
converter has an adjustable oversampling ratio. The CLKIN pin of the MCP3911 is the
oversampling clock (MCLK) input. The MCP3911 ADC Evaluation Board for 16-Bit
MCUs offers two different options for the MCP3911 master clock (MCLK).

Using the Crystal X1
The MCP3911 ADC Evaluation Board for 16-Bit MCUs is populated with a 3.58 MHz
crystal, used as a clock source, by placing jumpers in the following position on the
MCP3911 Digital I/O header block:
CLKOUT
CLKIN

Driving the Clock with the PIM Module
The PIC® MCU can be used to generate the CLKIN (MCLK) signal for the MCP3911,
setting the ADC sample rate through the use of the output compare module OC1. To
use this feature, make the following jumper change to the MCP3911 Digital I/O header
block:

Hardware Description
1.3
ANALOG INPUT STRUCTURE
Two differential input paths allow external signal sources to be easily connected to the
MCP3911 input. Screw-terminal connectors J2 and J5 are 3-pin connectors that act as
both screw-type and clip-on post connectors.
Note:
To use a screw-terminal connector as a post connector, pull up the blue
plastic top to access the posts.
The connectors J2 and J5 can be used to force either channel from a differential to
single-ended configuration. R4 and R11 (on CH0), and R19 and R21 (on CH1) act as
locations for burden resistor connectors for any current transformer inputs.
1.4
UNIVERSAL SERIAL BUS (USB)
The MCP3911 ADC Evaluation Board for 16-Bit MCUs also contains a USB connection
for connecting the evaluation board to a PC. On the board, there is an MCP2200 USB
to UART converter that creates a virtual COMM port on the PC. The MCP3911 ADC
Evaluation Board for 16-Bit MCUs also features a RS232 connector, just in case it is
required. The RS232 line driver is connected to the same UART pins of the MCU. For
this reason, a 3-pin jumper (J16) is present on the evaluation board to select which
serial communication will be used: USB or RS232. The following figure summarizes the
connections between the ADC, MCU, USB to serial converter and the RS232 line
driver.

FIGURE 1-5:
USB Block Diagram.
The MCP2200 is powered from the USB with 5V. The Q1 transistor (see Appendix A.)
is used to disconnect the board from the PC when it is powered down to avoid power
consumption.
Since the PIC24F runs at 3.3V, a level shifter was used to modify the signal level to 5V
as required by the MCP2200; this is done with U11 (see Appendix A.).
The 7.3728 MHz value of the crystal is required to achieve the correct baud rate values
for higher speed. This design uses a baud rate of 920.6 kbaud and for this baud rate,
the register value is 3 (decimal).
