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: 1.2 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 hardware description of the Cypress 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. 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. Because of the 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.

BIU LED [DS5] This is a yellow LED that glows when the transmit frequency band is in use. S1 Reset switch to reset the CY8CPLC10 device. S2[3-5] These dip switches are used to set up the logical address of the node in the network. This is an easy way for you to quickly assign an address from 0 to 7 to the board in a network. S1[3] is MSB and S1[5] is LSB for logical address assignment. S2[2] This dip switch sets the I2C slave address to establish the communication with a host processor. Setting the switch to OFF or ON sets the I2C address to external 0x01 or 0x7a respectively. S2[1] 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. Y1 This 32.768 kHz crystal is required for establishing the correct protocol timing and communication signal frequencies of the CY8CPLC10.

J8 I2C Header Pins J8 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 CY3273 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 through the external board. Note that the RES jumper, as explained in the next section, must be connected to enable this functionality. Figure 3-6. I2C Header for Communication 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 24 CY3273 Cypress Low Voltage Powerline Communication Evaluation Kit Guide, Doc. # 001-55382 Rev. *C [+] Feedback PLC LV Evaluation Board 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 these 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 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 further details on I2C addressing, refer to the data sheet available on the CD. 3.4.4 Jumper Settings for the PLC LV Boards Figure 3-8.

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 CY3273 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. After this jumper is 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 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). RES 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 the I2C header (J8). SCL This is a pull up jumper. While communicating through I2C (J8), one side has to pull up the line. When the jumper is connected, the SCL line gets pulled high. This needs to be done when the user wants the I2C link to be pulled up by the CY3273 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 (J8), one side has to pull up the line. When the jumper is connected, the SDA line is pulled high. This must be done when the user wants the I2C link to be pulled up by the CY3273 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. 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 Communication 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.
