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

Chapter 1. Product Overview
1.1
OVERVIEW
The MCP3914 ADC Evaluation Board for 16-Bit MCUs system provides the opportunity
to evaluate the performance of the MCP3914 eight-channel AFE. It also provides a
development platform for 16-bit PIC® device-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 device-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.
The MCP3914 ADC Evaluation Board for 16-Bit MCUs uses the Energy Management
Utility software for evaluation of the MCP3914 via a USB connection to the board. A
download link for this software can be found on the evaluation board’s web page. For
instructions on the use of this software, refer to the supporting documentation included
within the application install package.
1.1.1

Ports A, D, and G are used for signals such as push buttons, output LEDs, CS and
MCLR (for MCP3914 data mode setting). Output Compare 1 is used for clock generation in the MCP3914. Serial communication is achieved through the MSSP module 1.
The MCP3914 device is an AFE with eight ADCs featuring a second order modulator
and a third order sinc filter, plus a first order sinc filter used for higher OSR’s values.
The delta-sigma A/D converters have an adjustable oversampling ratio. The CLKIN pin
of the MCP3914 is the oversampling clock (MCLK) input. The MCP3914 ADC Evaluation Board for 16-Bit MCUs offers two different options for the MCP3914 master clock
(MCLK). The default setting for the ADC internal clock is external clock driven by the
MCU.
2.1.1
Using the Crystal X1
The MCP3914 ADC Evaluation Board for 16-Bit MCUs is populated with a 10 MHz
crystal, used as a clock source, by placing jumpers in the following position on the

ANALOG INPUT STRUCTURE
Eight differential input paths allow external signal sources to be easily connected to the
MCP3914 inputs. Screw-terminal connectors J1, J4, J7, J21, J23, J25, J27 and J29 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 J1, J4, J7, J21, J23, J25, J27 and J29 can be used to force either
channel from a differential to single-ended configuration. R4 and R11 (on CH0), R19
and R21 (on CH1) R18 and R65 (on CH2), R69 and R71 (on CH3), R75 and R77 (on
CH4), R81 and RR83 (on CH5), R87 and R89 (on CH6) and R93 and R95 (on CH7)
act as locations for burden resistor connectors for any current transformer inputs.

Hardware Description
2.3
UNIVERSAL SERIAL BUS (USB)
The MCP3914 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 MCP3914 ADC
Evaluation Board for 16-Bit MCUs also features a RS-232 connector, just in case it is
required. The RS-232 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 RS-232. The following figure summarizes
the connections between the ADC, MCU, USB to serial converter and the RS-232 line
driver.

FIGURE 2-4:
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. By changing the jumper J9 setting, the user can select the source of the
power supply for the board to be either +5V derived from USB or an external +9V power
supply.
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 921.6 kbaud and for this baud rate,
the register (U1BRG) value is 3 (decimal).

Chapter 3. Firmware
3.1
PIC24FJ256GA110 FIRMWARE DESCRIPTION
3.1.1
MCU Initialization
The microcontroller used for the code example is the 16-bit XLP with 16 MIPS
PIC24FJ256GA110. The MCU has remappable pins and output compare with a
dedicated time base.
The MCU uses a 7.3278 MHz crystal for the clock and the internal PLL to increase the
frequency by four times. The uncommon crystal value was chosen to obtain the correct
baud rate, even for high baud rates. The remappable pins are configured to make the
PIM compatible with the Explorer 16 development board. The MCP3914 is linked with
the MCU through the SPI1 port. The ADC clock is given by OC1. The DR pin of the
MCP3914 is tied to external Interrupt 2.
Serial data transmission is carried out through the UART2 module. For transmission,
OC2 interrupt is used; for receiving, the _U1RX Interrupt is used. The UART communication speed is 921.6 kbaud. OC2 is used for the serial transmission to create short
bursts of data that can be processed by the MCP2200. Sending too many characters,
with no time between them at the current baud rate, will cause the MCP2200 to lose
data.
Note:
3.2
The PIC24FJ256GA110 must be Rev. A5 or newer, in order for this code
example to work.
DATA ACQUISITION
External Interrupt 2 is used for detecting the end of conversion on the MCP3914. In the
INT2 Interrupt, the data samples are read from the ADC using SPI.
When a new buffer begins to be read, Timer4 is started. This is set as a 32-bit timer
together with Timer5. It will be stopped when the buffer is full and it is used to measure
the sampling speed.
Before reading the date samples, the MCU investigates the address loop setting
(READ <1:0> bits) in the STATUSCOM register and adjusts the read sequence accordingly (when the address is not incremented automatically in hardware, the MCU has to
do that in firmware, leading to a longer read sequence). The acquired samples are
written in six long vectors created in the RAM of the MCU. The six vectors hold the first,
second and third byte from both channels.
The vectors have a length of 2048. The value of Timer 4, and the values of the other
registers inside the ADC, are stored in a vector called “internal_registers[26]”.

MCP3914 ADC Evaluation Board for 16-Bit MCUs User’s Guide
3.3
UART COMMUNICATION PROTOCOL
The serial connection is used to send the acquired data to the PC at a speed of
921.6 kbaud, and the MCP2200 is used for the UART-to-USB conversion.
The communication uses handshaking, meaning that the board will not send data to
the PC unless the board receives a command from the PC.
The UART transmission is triggered by the output compare module OC2.This allows
the data to be transmitted to the PC in short bursts that are separated by a dead time.
This way of sending data allows the MCP2200 to handle the high throughput. If the
entire amount of data is sent continuously to the PC at the current baud rate, the
MCP2200 will not be able to process the data for correct USB transfer.
After a complete transmission, the UART RX interrupt is enabled by increasing its priority, while all other interrupts have lower priorities. In this interrupt, the MCU needs to
receive the values of the internal registers as the user is setting them in the PC GUI.
