1 Introduction
The Teridian™ 78M6618 PDU1 evaluation board is an example of a low-cost power distribution unit
(PDU) utilizing the 78M6618 system-on-chip (SoC). The 78M6618 monitors the AC line voltage and eight
load currents, and controls switching of eight internal load relays. The embedded firmware calculates the
RMS line voltage and RMS load currents, watts, VAs, VARs, and power factor. The real-time data is
transmitted to a PC via a USB interface for display in a Windows®-based graphical user interface (GUI).
The 78M6618 UART interface is used as the communications link to an on-board isolated USB interface
IC.
Included with the 78M6618 PDU1 is a Windows-based GUI for simplified access to the following
measurement data and controls:
•
•
•
•
•

1.3 Safety and ESD Notes
EXERCISE CAUTION WHEN LIVE AC VOLTAGES ARE PRESENT!
Standard ESD precautions must be taken when handling electronic equipment. The
78M6618 PDU1 contains ESD protected interfaces.
Do not connect test equipment, ICE emulators or external development boards directly to the
78M6618 hardware. Damage to the 78M6618 PDU1 and external equipment will occur due to the
78M6618’s “high side” reference topology. The 78M6618’s V3P3 (i.e., “high side”) is connected
directly to Neutral (Earth Ground) and the ground is 3.3V below neutral, creating a ground
reference disparity with any properly grounded external equipment. Also, reversing the line and
neutral connections at the inlet would place the board’s ground reference at the AC line voltage.
Always use the isolated USB interface for connecting to a PC. Contact the factory for instructions
on connecting other types of test equipment.
The board components and firmware settings are designed to operate with the following nominal AC
electrical ranges:
Voltage
Current
Line Frequency
110-240 VAC
20A Max
46-64 Hz
1.4 Firmware Demo Code Introduction
The Firmware Demo Code provides the following features:
•
•
Basic energy measurement data such as Watts, Volts, current, VAR, VA, phase angle, power factor,
accumulated energy, frequency, date/time, and various alarm statuses.
Control of alarm thresholds, calibration coefficients, temperature compensation, etc.
There are two means to facilitate performance evaluation between the user at the PC host and the
firmware code in the 78M6618 PDU1 evaluation board:
•
The graphical user interface (GUI). For information about the GUI, refer to the GUI User Guide.
•
The Command Line Interface (CLI) via HyperTerminal or comparable terminal emulator on a different
operating system. For information about the CLI, see the Firmware Description Document.
The 78M6618 PDU1 evaluation board is shipped with demonstration code loaded in the 78M6618 device
and included on the CD. The code revision can be verified by entering the command >i via the command
line interface. Firmware for the Demo Unit can be updated using either the Teridian TFP2 or an in-circuit
emulator such as Signum Systems ADM51 (www.signum.com).

FTDI COM Port Trouble-Shooting
If the FTDI device driver did not install properly, there would be no assigned COM port
number for the FTDI controller. Repeat the USB Driver Installation, see Section 2.1.
Microsoft Windows may associate a Ball Point device to the FTDI USB controller. When this
occurs a FTDI device COM port assignment is available via HyperTerminal but there is no
communications data. Verify if a Ball Point device has been added to the “Human Interface
Devices” via the Device manager. Refer to Section 2.3 for access to the Device Manager. If
a Ball Point device exists, delete it and unplug and replug the evaluation board’s USB cable.
2.5 Connect the AC Source and Load
Connect the desired AC source to the terminal block J4. Be sure to observe the correct connections for
line and neutral as they are designated on the silk screen. Terminal block J4 accepts bare wires size
24AWG to 10AWG. Be sure to select wire gauge appropriate to the total load to be applied to the board,
and make sure that the screws are tightened for good electrical connection and wire retention.
The loads to be controlled and metered are connected to the screw terminals J7-J22 that are located on
the bottom edge of the board. These terminals can accept bare wire, or spade terminals or ring terminals
that are capable of accepting a 6-32 screw. The individual terminals are rated to carry a maximum current
of 15A. As with the AC inlet connection, be sure to observe proper connection to the AC line (labeled
Outlet n) and AC neutral.

The main functional blocks of the evaluation board are the 78M6618 energy measurement SoC, voltage
regulators, input signal conditioning, and relay control.
3.1
78M6618
The 78M6618 is a highly integrated IC for energy monitoring and measurement. The key features of the
78M6618 include:
•
A 21-bit delta sigma analog to digital converter (ADC) with 10 multiplexed analog inputs
•
•
A 32-bit digital signal processor core (Compute Engine, or CE)
An 8-bit microprocessor core
•
•
•
128 Kbytes flash memory
32,768 kHz oscillator
Up to 19 general-purpose digital I/O pins (DIO).
For detailed information on the 78M6618, refer to the 78M6618 Data Sheet.
3.2
Voltage Regulators
The evaluation board is powered by an external 12VDC source. The on-board relays for switching power
to the 8 outlets are powered directly from the 12V supply. Linear regulators are used to provide the 3.3V
supply for the 78M6618 and external logic and a 6.6V supply for the operational amplifiers that are used
to amplify the voltage from the current sense resistors.
Rev 3

78M6618 PDU1 Evaluation Board User Manual
3.3
UM_6618_022
Input Signal Conditioning
Input signal conditioning includes the voltage divider used to reduce the AC line voltage to a level that can
be measured by the 78M6618, the differential amplifiers that are used to remove common-mode voltage
from the input signals to the ADC current channels, and the low-pass filters that block high-frequency
signal content from the ADC inputs.
3.4
Relay Control
Power to each of the 12 outlets on the board is switched by a relay. The relays are individually controlled
by digital I/O (DIO) lines from the 78M6618. Do to the type of relay driver circuit used on this board, the
firmware Relay Config register (0x0210) is set equal to 2. This inverts the relay driver input polarity.
3.5
Theory of Operation
Before describing the operation of the PDU, it may be helpful to make note of some of the characteristics
of the 78M6618 and the board design.
1. The reference for the 78M6618’s ADC is its positive power supply (V3P3), not ground.
2. The 78M6618’s 3.3V power supply is directly connected to the neutral side of the AC power source.
As a result, the 78M6618’s ground reference is actually 3.3V below the AC neutral.
3.5.1
78M6618 Operation
The analog multiplexer at the front end of the delta-sigma ADC sequentially presents the signals at the 10
analog input pins to the ADC, which converts them to digital words which are presented to the 32-bit
compute engine (CE). The CE performs filtering and calculates RMS voltage and current, line frequency,
real power and reactive power. The CE transfers its results to the 80515 MPU at the end of each
accumulation interval. The accumulation interval, which is the period over which RMS voltage, current
and power are calculated, is determined by the firmware loaded into the 78M6618’s internal flash, and
may be between 200 milliseconds and 1 second. The 80515 MPU performs some scaling of the CE
results, calculates some additional values, and manages the communication with an external host via its
integrated UART. The MPU also controls the operation of the CE.
3.5.2
Voltage and Current Measurement
As previously described, the reference voltage for the 78M6618 ADC is 3.3V. The valid input range for
the ADC is 3.3V ±250 mV. A 250 mV signal corresponds to full scale on the ADC. A voltage divider is
used to scale the line voltage to the ±250 mV range of the ADC. The voltage divider consists of 2 1 MΩ
resistors and one 750 Ω resistor. The ADC measures the voltage across the 750Ω resistor, which is
0.0375% of the line voltage. With this ratio, the ADC can measure line voltages up to 667VPEAK, which
corresponds to a sinusoidal voltage input of ~471 VRMS. An RC low-pass filter at the input to the ADC
limits the frequency content of the input signal to around 4,500 Hz.
The PDU uses current sense resistors, also known as shunt resistors, to sense the current flowing in the
neutral or return of each outlet. The value of the current sense resistor is selected to scale the voltage
drop across the resistor to the input range of the ADC. The sense resistors must also have low resistance
values in order to keep voltage drop and power dissipation to acceptable levels. The 78M6618’s ADC has
single ended inputs referenced to V3P3. The PCB traces that are used for the line and neutral buses on
the PDU board have resistances that are of the same magnitude or greater than that of the acceptable
shunts. This parasitic resistance appears between the reference end of the sense resistors and the ADCs
reference point, as illustrated by Figure 4. If the sense resistors are corrected directly to the ADC inputs
as shown in Figure 5, it is impossible to separate the voltage across the sense resistors from the voltage
across the parasitic resistance in the PCB. Because of this, current flowing in one outlet will affect the
voltage at the ADC current measurement inputs for other channels, resulting in channel-to-channel
crosstalk. To eliminate this problem, differential amplifiers are used between the current sense resistors
and the ADC current measurement inputs, as shown in Figure 5. The differential amplifier is biased to
provide an output centered at 3.3V, and rejects the voltage drop due to the PCB resistance, which
appears as common mode voltage at the amplifier inputs, so that the signal presented at the ADC input is
14

78M6618 PDU1 Evaluation Board User Manual
due only to the voltage drop across the current sense resistor. An additional advantage of using the
differential amplifier is that it is possible to use lower value sense resistors by increasing the gain of the
differential amplifier. The PDU evaluation board uses 500 µΩ sense resistors, with an amplifier gain of 10.
With this configuration, a peak current of 50A results in full-scale input to the ADC. This allows the PDU to
measure 16A loads with a crest factor slightly greater than 3.

Figure 7: ICE Adaptor
Figure 3 shows how to attach the ICE Adaptor to the 78M6618 evaluation board. Please make note of the
orientation of the ICE Adaptor as to how it attaches to the 78M6618 evaluation board (V3P3 ICE Adaptor
pin connects to the +V Evaluation Board pin).
Figure 8: 78M6618 ICE Adaptor Attachment
Disconnect the 78M6618 evaluation board from live AC voltages before connecting the
ADM51 or TFP2. An Earth ground disparity and high AC voltages are present on the
78M6618 evaluation board when it is connected to the AC outlet. Equipment damage to
the 78M6618, ADM51/TFP2 and attached PC may occur when live AC voltages are
present on the 78M6618 evaluation board. Refer to the 78M661x Safety Precautions
Applications Note for additional information.
It is recommended to always use the supplied flat ribbon cable. Do not use discrete wires in place of the
flat ribbon. Poor signal integrity will cause flash memory programming errors. Additional adaptors and flat
ribbon cables can be ordered through Maxim.
