Introduction
1.3
Using the Cypress PLC Solution
Powerlines are available everywhere in the world, which makes them one of the most widely available communication media. The pervasiveness of powerlines also makes it difficult to predict its
characteristics and noise. Because of the variability of the quality of powerline, implementing robust
communication over powerline has been an engineering challenge for years. With this in mind, the
Cypress PLC solution is designed to enable secure, reliable, and robust communication over powerline. Some of the features of Cypress PLC are:
■
Integrated powerline PHY modem with optimized filters and amplifiers to work with rugged high
voltage powerlines.
■
Powerline optimized network protocol that supports bidirectional communication with acknowledgement based signaling and multiple retransmit.
■
Support for 8-bit packet CRC and 4-bit header CRC for error detection and data packet retransmission.
■
Carrier Sense Multiple Access (CSMA) scheme that minimizes collisions between packet transmissions on the powerline.
The Cypress PLC solution contains three key elements as shown in Figure 1-1.

Powerline Network Protocol Layer
■
Physical Layer frequency shift keying (FSK) Modem

coupling circuit for communicating on high voltage (110 to 240 V AC) powerlines. For a detailed
description of the design parameters for the circuit, refer to the application note "Cypress Powerline
Communication Board Design Analysis - AN55427".
The CY8CPLC10 device is controlled by an external host microcontroller via an I2C interface. To
evaluate this kit, an external host must be created.
■
The first option is to use a PC to install and run the Cypress PLC Control Panel GUI, which is
included with this kit. The PC interfaces to the CY3272 board via the CY3240-I2USB Bridge
board that is included with this kit. Steps for setting up this system are provided in the quick start
guide, which is provided in the kit.
■
The second option is to use an external microcontroller that is running a host application. The
application note, AN52478 - Designing an External Host Application for Cypress's Powerline
Communication IC CY8CPLC10, provides an example project that can be programmed on a
PSoC microcontroller board (in this case, the CY3210-PSoCEVAL1) and explains how to interface it to the CY3272 board. This application note is provided with this kit.
Note To evaluate this kit, a second high voltage PLC kit is required. The compatible kits are CY3272
(this kit) and CY3274 High Voltage PLC Development Kit. For information on these kits, visit

Functional Overview
The PLC evaluation board is designed as an advanced evaluation, testing, and product development
platform for low bandwidth (2400 bps) powerline communication.
Data to be transmitted is sent to the CY8CPLC10 through the I2C serial communications interface
using a serial bridge driver to a PC or PSoC device. The serial bridge application on the
CY8CPLC10 receives this I2C data and encapsulates it into a PLC Network packet. The on-board
FSK modem modulates this packet and the coupling circuitry incorporates the resulting sinusoidal
waveform onto the existing waveform on the high voltage powerline bus.

PLC HV Evaluation Board
3.4
Setting Up the PLC HV Board
This section describes the components of the PLC HV Evaluation Board, the process of setting manual addresses on the PLC HV Board and the connection of USB-I2C Bridge and I2C Cable to the
I2C header on the board.
Figure 3-6. DIP Switches for Manual Addressing on the PLC Evaluation Boards
3.4.1
Setting Up Manual Addressing on PLC Boards
The PLC Evaluation Board contains a five-position DIP switch (S1). The three switches S1[3-5] are
used to manually set a logical address for the PLC chip. Logical Addresses for up to 8 nodes can be
set up using these DIP switches.
S1[3] is the MSB. S1[5] is the LSB. Set the dip-switch to the ON position for the particular bit to be
logic '1' and the OFF position for it to be logic '0'. For example, for setting logical address of 0X06:
S1[3] → ON = 1
S1[4] → ON = 1
S1[5] → OFF = 0
Note that the powerline network protocol supports 8-bit logical addressing, 16-bit extended logical
addressing, and 64-bit physical addressing; all of these are supported through software. An external
host microcontroller or a PSoC can talk to the CY8CPLC10 memory map to set the appropriate
mode and configure a particular logical address.
Manual addressing is an easy method to quickly assign a particular address between 0 and 7 to the
board which may be a node in a network.
Note After changing the address of the node, the RESET button on the board must be pressed on
the PLC HV Board for the change to take effect.
3.4.2
Setting Up I2C Address of the Node
I2C DIP switch S1[2] is used to assign a specific I2C address to the node for communicating with the
external microcontroller/PSoC or USB-I2C bridge. When the I2C switch S1[2] is in the OFF position,
the address of the node is 0x01 and when it is in the ON position, the address of the node is 0x7A.
For further details on I2C addressing, refer to the device data sheet, which is on the CD.
3.4.3
I2C Header Settings
The I2C header, J5, is a five pin header that can be used for communicating with an external board,
powering an external board, and resetting the CY8CPLC10 device from an external board. A five
wire ribbon cable is provided with this kit for use on the J5 header. The description for J5 header pins
is as follows:

Table 3-5. J5 I2C Header Pins
J5 Pin Name
Description
V – Vdd
The Vdd pin can provide a maximum of 50 mA at 5 V to an external board. It is only
to source the current. DO NOT SUPPLY POWER TO THIS PIN FOR POWERING
THE CY8CPLC10 DEVICE. Note that the PWR jumper, as explained in the next
section, needs to be connected to enable this functionality.
G – Gnd
The Gnd pin can provide the ground reference to an external board. This pin connects to the ground of the CY3272 board.
D – I2C Data (SDA)
The I2C Data (SDA) pin is the data line for the I2C communication. This pin is
directly connected to the I2C_SDA pin on the CY8CPLC10 device. Check the next
section for appropriate jumper settings for I2C communication through this pin.
C – I2C Clock (SCL)
The I2C Clock (SCL) pin is the clock line for the I2C communication. This pin is
directly connected to the I2C_SCL pin on the CY8CPLC10 device. Check the next
section for appropriate jumper settings for I2C communication through this pin.
R – Reset
Connecting the reset of an external board to this pin enables the resetting of the
CY8CPLC10 device via the external board. Note that RES jumper, as explained in
the next section, needs to be connected to enable this functionality.

Table 3-6. Jumper Description
Jumper Name
Use
INT
This is not a jumper. It is a 2-pin header to connect the interrupt pin of the CY8CPLC10
device to an external host. Refer to the CY3272 board schematics to determine interrupt
and ground pins for this header.
PWR
This jumper should be connected if the user wants to provide power to an external board.
Once this jumper has been connected, power for the external board can be derived from
the V (Vdd) and G (Gnd) connectors on the I2C header (J5). For example, if we connect
another PSoC EVAL1 board with this board, the PLC board can supply power to that
board as well. The CY3272 board can provide a maximum of 50 mA at 5 V to an external
board through the V and G pins on the I2C header (J5).
RES
This jumper is for enabling Reset of the PLC device through an external board. Once this
jumper has been connected, the external board reset can be connected to the R (Reset)
pin on the I2C header (J5).
SCL
This is a pull up jumper. While communicating through I2C (J5), one side has to pull up
the line. When the jumper is connected, the SCL line will get pulled high. This needs to be
done when the user wants the I2C link to be pulled up by the CY3272 board.
This jumper does not need to be placed if the USB-I2C bridge is used for communication
to the host.
SDA
This is a pull up jumper. While communicating through I2C (J5), one side has to pull up
the line. When the jumper is connected, the SDA line will get pulled high. This needs to be
done when the user wants the I2C link to be pulled up by the CY3272 board.
This jumper does not need to be placed if the USB-I2C bridge is used for communication
to the host.
CLK
3.5
This jumper is not available for use and should be left unconnected by the user.
Example Project
The CY3272 kit is designed for systems that require a communication interface over commercial
high-voltage Powerlines. Typically, these systems consist of a microcontroller or processor along
with other electronic components that implement the host application functionality. For more information on this interface, see AN52478 Designing an External Host Application for Cypress's Powerline
Communication IC CY8CPLC10.
