1. Introduction
1.1 Introduction to the Cypress PLC Solution
Cypress’s Powerline Communication Solution (PLC) enables transmission of command and control
data over high voltage and low voltage powerlines. This solution is developed for low bandwidth
powerline communication.
The CY3273 PLC Low Voltage (LV) Evaluation Board demonstrates the ability of the Cypress
CY8CPLC10 to transmit data at 2400 bps over low voltage (12 V to 24 V AC/DC) powerlines.
This guide includes the following chapters:
■ Chapter 1 provides a brief overview of the Cypress PLC solution. It describes the contents of the
CY3273 evaluation kit and lists additional requirements to run the code examples, which are
included as part of the kit.
■ Chapter 2 gives the functional and high level hardw ar e descr ip tion of th e Cyp re ss PLC LV
boards. It also describes the setup and operating procedure of the PLC LV board. It describes
features such as manual addressing, connection of USB-I2C bridge, and jumper settings with
examples.
■ The Appendix contains the schematics, layout, and bill of materials.
1.2 Using the Cypress PLC Solution
Powerlines are one of the most widely available communication media in the world. The
pervasiveness of powerlines makes it difficult to predict its characteristics and noise. Becaus e o f th e
variable 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 amplifiers to work with rugged low voltage
powerlines.
■ Powerline optimized network protocol that supports bidirectional communication with
acknowledgement based signaling and multiple retries.
■ 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 consists of three key elements as shown in Figure 1-1.
■ Powerline network protocol layer
■ Physical layer frequency shift keying (FSK) modem
■ Power amplification and coupling circuits

This inductor, along with C30, filters out low frequency signals (for example, 50/60 Hz AC or
DC power) and presents a high impedance to the 132 kHz PLC signal.
This is the coupling capacitor that couples the PLC signal and blocks the low frequency signals. Its voltage rating must be higher than the voltage on the powerline..

This dip switch controls the clock setting to the CY8CPLC10. Setting the switch to 0 or 1
sets the FSK modem clock to external 32 kHz crystal or external 24 MHz oscillator,
respectively. Note that the external crystal is always required for protocol timing.

D – I2C Data (SDA)
C – I2C Clock (SCL)
R – Reset
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.
The Gnd pin can provide the ground reference to an external board. This pin connects to the ground of the CY3273 board.

Connecting the reset of an external board to this pin enables the resetting of the
CY8CPLC10 device through the external board. Note that the RES jumper, as
explained in the next section, must be connected to enable this functionality.

3.4.2 Setting Up Manual Addressing on PLC Boards
The PLC evaluation board contains a five-position DIP switch. The first three switches S2[3-5] are
used to manually set a logical address for the PLC chip. Logical addresses for up to eight nodes can
be set up using these DIP switches.
S2[3] is the MSB. S2[5] is the LSB. Set the DIP switch to the ON position for the particular bit to be
logic ‘1’ and OFF position for it to be logic ‘0’. For example, for setting the logical address of 0X06
(see Figure 3-7):
S2[5] → OFF = 0
S2[4] → ON = 1
S2[3] → ON = 1

Figure 3-7. DIP Switches for Manual Addressing on the PLC Evaluation Boards
Note that the powerline network protocol supports 8-bit logical addressing, 16-bit extended logical
addressing, and 64-bit physical addressing; all of th ese are supported through software. An external
host or PSoC microcontroller can talk to the CY8CPLC10 internal memory map to set the appropriate mode and write 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, press the RESET button on the PLC LV board for the
change to take effect.
3.4.3 Setting Up the I2C Address of the Node
PLC LV Evaluation Board
S2[1] dip switch is used to assign a specific I2C address to the node to communicate with the external microcontroller/PSoC or USB-I2C bridge. When the S2[1] switch is in the OFF position, the
address of the node is 0x01 and when the position is ON, the address of the node is 0x7A. For fur-
ther details on I

C addressing, refer to the data sheet available on the CD.

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 CY3273 board schematics to determine interrupt
and ground pins for this header.
This jumper should be connected if the user wants to provide power to an external board.
After this jumper is connected, power for the external board can be derived from the V

another PSoC EVAL1 board with this board, the PLC board can supply power to that
board too. The CY3273 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).
This jumper is for enabling reset of the PLC device through an external board. After this
jumper is connected, the external board reset can be connected to the R (Reset) pin on

3.5 Code Example
The CY3273 kit is designed for systems that require a communication interface over low 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, refer to AN52478 - Designing an External Host Application for Cypress's Powerline Com-
munication IC CY8CPLC10.
3.6 Technical Reference
For a real-time list of knowledge base articles for the CY3273 kit, refer to our Online Knowledge
Base. For any help with the installation of the Control Panel, refer to the Control Panel User Guide
provided in the kit CD. You can also download the latest revision of the GUI setup and user guide
