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

2.3
GETTING STARTED
The following example is given to describe how to use this evaluation board using a
current-sensing shunt, 220 VAC line voltage and a 10A load. All connections described
in this section are dependent on the choice of current-sensing element. A 250 µΩ shunt
is selected as the current-sensing element.
2.3.1
Step 1: Install Current-Sensing Element and Make Appropriate
Input Connections
Use the input prototype area to connect the line/load and current-sensing elements to
the appropriate screw-type connector. An example of connecting the shunt is shown in
Figure 2-2. Please note that the phase-side of the line should be used as the GND
reference to the MCP3905A/06A Evaluation Board when using the AC/DC power
supply circuit in shunt examples like the one in Figure 2-2.

Resistor sockets R11 and R12 should be left open when using a shunt. JP3, JP13 and
JP14 should also be open. This configuration puts the shunt across the channel inputs

Step 5: Select +5V Source
With the connections for J9 and J11 made in Figure 2-2, the 220V AC/DC power supply
circuit can be used as the +5V supply. Here we put JP4 in the “INT” position for internal
connection.
2.3.6
Step 6: Connect Line and Load and Observe MCP3905A Output
Once all jumper positions have been selected, connecting 220V with the correct L,G,N
connections and an appropriate load (10A in this example) will power both the
MCP3905A/06A Evaluation Board and create the MCP3905A output (LED, BLINKING)
in Figure 2-5.

MCP3905A/06A EVALUATION BOARD OVERVIEW
The functional blocks of the MCP3905A/06A Evaluation Board will be described in this
section. For more detailed information regarding design decisions and approaches to
IEC1036 compliance, refer to AN994, “IEC Compliant Active Energy Meter Design
Using The MCP3905A/06A” (DS00994). For a detailed circuit schematic, refer to

FUNCTIONAL BLOCK DESCRIPTIONS
2.5.1
Input Prototype Area
All line/load, shunt and CT connections are to be made next to the screw-type
connectors J5-J12. This area includes two mounting holes for a standard shunt
connector. All high-voltage connections go onto this prototype area.
2.5.2
High-Voltage Input Connections (J5-12)
These screw-type connections are for shunts, CTs, line and load. The shunt resistance
should be placed in parallel with J5 and J6. A variety of experiments using shunts and
CTs can be performed here in conjunction with the input prototype area.
J9 and J10 feed the AC/DC power supply circuitry. J10 is the reference connection to
the entire board. Shunt-type meters should be connected to the line-side. One example
is given in the figure below.

Channel 1 RC Circuit with AGND Option – Circuit A
Channel 1 is a differential input with two possible circuit selections for each
single-ended input (circuit A and circuit B). Using the MCP3905A/06A Evaluation
Board, either of the inputs can be connected to the RC or to AGND, allowing
single-ended or differential experiments. JPX should be shorted to ground for all
single-ended input configurations.

2.5.8
DC Power Supply
A low-cost DC power supply circuit is included on the MCP3905A/06A Evaluation
Board. This is the same DC power supply circuit used in the MCP3905A/06A Energy
Meter Reference Design. The DC power supply is created from a half-wave zener
diode-limited AC signal feeding a 7805 +5V regulator.
C17 and C16 divide the AC signal coming directly from the line, with their values
depending on the AC source expected. The board comes populated with a series
capacitor of 0.47 µF, designed to divide down an AC line voltage of 220 VRMS. If the DC
power supply is to be used with a 120 VRMS AC source capacitor, C16 should change
to 1 µF. Refer to Appendix B. “Bill Of Materials (BOM)” for detailed part information.
For more detail on this circuit design, as well as for 120V circuit specifications, refer to
AN994 “IEC Compliant Active Energy Meter Design Using The MCP3905A/06A”
(DS00994).
2.5.9
Output Prototype Area
A second prototype area is included for experiments using the MCP3905A output.
All MCP3905A outputs (FOUT0, FOUT1, HFOUT, REVP) are brought out to the prototype
area.

Starter Kit Connector
A standard 14-pin PICtail™ daughter board connector is included on this board, as
shown in Figure 2-12. Any number of MCP3905A with PICmicro MCU meter designs
can be developed. An optical isolator is included with the MCP3905A/06A Energy
Meter Reference Design as an additional level of protection for direct-connect meters
using a shunt. It is connected to the selected output of the MCP3905A via JP5.
A pull-up resistor is required on the output of the optical isolator to allow the selected
logic signal to appear on the PICmicro MCU-based demo board, which is isolated
entirely from the MCP3905A/06A Evaluation Board. The output of the optical isolator
is connected to RC0 on this connector, as shown in Figure 2-12. RC0 was chosen to
be the default output due to the timer1 clock input on many PICmicro® MCUs.
