PLC Functional Overview The CY8CPLC20 is an integrated powerline communication (PLC) chip with the powerline modem PHY and network protocol stack running on the same device. Apart from the PLC core, the CY8CPLC20 also offers Cypress's revolutionary PSoC technology that enables system designers to integrate multiple functions on the same chip. The physical layer of the Cypress PLC solution is implemented using an FSK modem that enables half duplex communication on any high voltage and low voltage powerline. This modem supports raw data rates up to 2400 bps. A block diagram is shown in Figure 2-2 Figure 2-2. Physical Layer FSK Modem Block Diagram Network Protocol 2.1 Robust Communication using Cypress’s PLC Solution Powerline optimized network protocol that supports bidirectional communication with acknowledgement-based signaling. In case of data packet loss due to bursty noise on the powerline, the transmitter has the capability to retransmit data. ■ The powerline network protocol also supports an 8-bit CRC for error detection and data packet retransmission. ■ A Carrier sense multiple access (CSMA) scheme is built into the network protocol that minimizes collisions between packet transmissions on the powerline and supports multiple masters and reliable communication on a bigger network. 2.2 Powerline Modem PHY Figure 2-1.

Local Oscillator Transmitter ■ Digital Receiver Digital Transmitter Powerline Modem PHY Powerlines are available everywhere in the world and are a widely available communication medium for PLC technology. The pervasiveness of powerlines also makes it difficult to predict the characteristics and operation of PLC products. Because of the variable quality of powerlines around the world, implementing robust communication has been an engineering challenge for years. The Cypress PLC solution enables secure and reliable communications. Cypress PLC features that enable robust communication over powerlines include: HF Band Pass Filter RX Amplifier Coupling Circuit 2.2.1 Transmitter Section Digital data from the network layer is serialized by the digital transmitter and fed as input to the modulator. The modulator divides the local oscillator frequency by a definite factor depending on whether the input data is high level logic ‘1’ or low level logic ‘0’. It then generates a square wave at 133.3 kHz (logic ‘0’) or 131.8 kHz (logic ‘1’), which is fed to the Programmable Gain Amplifier to generate FSK modulated signals. This enables tunable amplification of the signal depending on the noise in the channel. The logic ‘1’ frequency can also be configured as 130.4 kHz for wider FSK deviation. 2.2.2 Receiver Section The incoming FSK signal from the powerline is input to a high frequency (HF) band pass filter that filters out-of-band frequency components and outputs a filtered signal within the desired spectrum of 125 kHz to 140 kHz for further demodulation. The mixer block multiplies the filtered FSK signals with a locally generated signal to produce heterodyned frequencies. Page 3 of 56 CY8CPLC20 The intermediate frequency (IF) band pass filters further remove out-of-band noise as required for further demodulation. This signal is fed to the correlator, which produces a DC component (consisting of logic ‘1’ and ‘0’) and a higher frequency component. The output of the correlator is fed to a low pass filter (LPF) that outputs only the demodulated digital data at 2400 baud and suppresses all other higher frequency components generated in the correlation process. The output of the LPF is digitized by the hysteresis comparator. This eliminates the effects of correlator delay and false logic triggers due to noise. The digital receiver deserializes this data and outputs to the network layer for interpretation. 2.2.3 Coupling Circuit Reference Design The coupling circuit couples low voltage signals from the CY8CPLC20 to the powerline. The topology of this circuit is determined by the voltage on the powerline and design constraints mandated by powerline usage regulations. Cypress provides reference designs for a range of powerline voltages including 110 V/240 V AC and 12 V/24 V AC/DC. The CY8CPLC20 is capable of data communication over other AC/DC Powerlines as well with the appropriate external coupling circuit. The 110 V AC and 240 V AC designs are compliant to the following powerline usage regulations: ■ FCC Part 15 for North America ■ EN 50065-1:2001 for Europe 2.3 Network Protocol Cypress’s powerline optimized network protocol performs the functions of the data link and network layers in an ISO/OSI-equivalent model. Figure 2-3. Powerline Network Protocol Powerline Communication Solution The network protocol implemented on the CY8CPLC20 supports the following features: ■ Bidirectional half-duplex communication ■ Master-slave or peer-to-peer network topologies ■ Multiple masters on powerline network ■ 8-bit logical addressing supports up to 256 powerline nodes ■ 16-bit extended logical addressing supports up to 65536 powerline nodes ■ 64-bit physical addressing supports up to 264 powerline nodes ■ Individual, broadcast or group mode addressing ■ Carrier Sense Multiple Access (CSMA) ■ Full control over transmission parameters ❐ Acknowledged ❐ Unacknowledged ❐ Repeated Transmit 2.3.1 CSMA and Timing Parameters ■ CSMA – The protocol provides the random selection of a period between 85 and 115 ms (out of seven possible values in this range) in which the band-in-use (BIU) detector must indicate that the line is not in use, before attempting a transmission. ■ BIU – A Band-In-Use detector, as defined under CENELEC EN 50065-1, is active whenever a signal that exceeds 86 dBmVrms anywhere in the range 131.5 kHz to 133.5 kHz is present for at least 4 ms. This threshold can be configured for different end-system applications not requiring CENELEC compliance.The modem tries to retransmit after every 85 to 115 ms when the band is in use. The transmitter times out after 1.1 seconds to 3 seconds (depending on the noise on the Powerline) and generates an interrupt to indicate that the transmitter was unable to acquire the powerline. 2.3.2 Powerline Transceiver Packet Powerline Network Protocol Programmable System Resources Digital and Analog Peripherals Physical Layer FSK Modem PLC Core Additional System Resources MAC, Decimator, I2C, SPI, UART etc. PSoC Core Powerline Transceiver Packet CY8CPLC20 Embedded Application The powerline network protocol defines a powerline transceiver (PLT) packet structure, which is used for data transfer between nodes across the powerline. Packet formation and data transmission across the powerline network are implemented internally in CY8CPLC20. A PLT packet is divided into a variable length header (minimum 6 bytes to maximum 20 bytes, depending on address type), a variable length payload (minimum 0 bytes to maximum 31 bytes), and a packet CRC byte. This packet (preceded by a one byte preamble “0xAB”) is then transmitted by the powerline modem PHY and the external coupling circuit across the powerline. The format of the PLT packet is shown in Table 2-1 on page 5. Document Number: 001-48325 Rev. *K Page 4 of 56 CY8CPLC20 Table 2-1. Powerline Transceiver (PLT) Packet Structure Byte Offset Bit Offset 7 0x00 6 SA Type 5 4 3 2 1 0 DA Type Service RSVD RSVD Response RSVD Type 0x01 Destination Address (8-Bit Logical, 16-Bit Extended Logical or 64-Bit Physical) 0x02 Source Address (8-Bit Logical, 16-Bit Extended Logical or 64-Bit Physical) 0x03 Command 0x04 Payload Length RSVD 0x05 Seq Num Powerline Packet Header CRC 2.3.6 Sequence Numbering The sequence number is increased for every new unique packet transmitted. If in acknowledged mode and an acknowledgment is not received for a given packet, that packet is re-transmitted (if TX_Retry > 0) with the same sequence number. If in unacknowledged mode, the packet is transmitted (TX_Retry + 1) times with the same sequence number. If the receiver receives consecutive packets from the same source address with the same sequence number and packet CRC, it does not notify the host of the reception of the duplicate packet. If in acknowledged mode, it still sends an acknowledgment so that the transmitter knows that the packet was received. 2.3.7 Addressing The CY8CPLC20 has three modes of addressing: 0x06 Payload (0 to 31 Bytes) ■ Logical addressing: Every CY8CPLC20 node can have either a 8-bit logical address or a 16-bit logical address. The logical address of the PLC Node is set by the local application or by a remote node on the Powerline. ■ Physical addressing: Every CY8CPLC20 has a unique 64-bit physical address. ■ Group addressing: This is explained in the next section. Powerline Transceiver Packet CRC 2.3.3 Packet Header The packet header contains the first 6 bytes of the packet when 1-byte logical addressing is used. When 8-byte physical addressing is used, the source and destination addresses each contain 8 bytes. In this case, the header can consist of a maximum of 20 bytes. Unused fields marked RSVD are for future expansion and are transmitted as bit 0. Table 2-2 describes the PLT packet header fields in detail. Table 2-2. Powerline Transceiver (PLT) Packet Header Field Name SA Type DA Type No. of Tag Bits 1 Source Address Type 2 Destination Address Type Service Type Response 1 1 Response Seq Num 4 Sequence Number Header CRC 4 2.3.8 Group Membership Group membership enables the user to multicast messages to select groups. The CY8CPLC20 supports two types of group addressing: ■ Single Group Membership – The network protocol supports up to 256 different groups on the network in this mode. In this mode, each PLC node can only be part of a single group. For example, multiple PLC nodes can be part of Group 131. ■ Multiple Group Membership – The network protocol supports eight different groups in this mode and each PLC node can be a part of multiple groups. For example, a single PLC node can be a part of Group 3, Group 4, and Group 7 at the same time. Description 0 – Logical Addressing 1 – Physical Addressing 00 – Logical Addressing 01 – Group Addressing 10 – Physical Addressing 11 – Invalid 0 – Unacknowledged Messaging 1 – Acknowledged Messaging 0 - Not an acknowledgement or response packet 1 - Acknowledgement or response packet 4-bit unique identifier for each packet between source and destination. 4-bit CRC value. This enables the receiver to suspend receiving the rest of the packet if its header is corrupted 2.3.4 Payload The packet payload has a length of 0 to 31 bytes. Payload content is user defined and can be read or written through I2C. 2.3.5 Packet CRC The last byte of the packet is an 8-bit CRC value used to check packet data integrity. This CRC calculation includes the header and payload portions of the packet and is in addition to the powerline packet header CRC. Document Number: 001-48325 Rev. *K Both these membership modes can also be used together for group membership. For example, a single PLC node can be a part of Group 131 and also multiple groups such as Group 3, Group 4, and Group 7. The group membership ID for broadcasting messages to all nodes in the network is 0x00. The service type is always set to Unacknowledgment Mode in Group Addressing Mode. This is to avoid acknowledgment flooding on the powerline during multicast. 2.3.9 Remote Commands In addition to sending normal data over the Powerline, the CY8CPLC10 can also send (and request) control information to (and from) another node on the network. The type of remote command to transmit is set by the TX_CommandID register and when received, is stored in the RX_CommandID register. When a control command (Command ID = 0x01-0x08 and 0x0C-0x0F) is received, the protocol automatically processes the packet (if Lock_Configuration is '0'), responds to the initiator, and notifies the host of the successful transmission and reception. Page 5 of 56 CY8CPLC20 When the send data command (ID 0x09) or request for data command (ID 0x0A) is received, the protocol replies with an acknowledgment packet (if TX_Service_Type = '1'), and notify the host of the new received data. If the initiator doesn't receive the acknowledgment packet within 500ms, it notifies the host of the no acknowledgment received condition. When a response command (ID 0x0B) is received by the initiator within 1.5s of sending the request for data command, the protocol notifies the host of the successful transmission and reception. If the response command is not received by the initiator within 1.5s, it notifies the host of the no response received condition. The host is notified by updating the appropriate values in the INT_Status register (including Status_Value_Change). The command IDs 0x30-0xff can be used for custom commands that would be processed by the external host (e.g. set an LED color, get a temperature/voltage reading). The available remote commands are described in Table 2-3 with the respective Command IDs. Table 2-3.

PSoC Core The CY8CPLC20 is based on the Cypress PSoC® 1 architecture. The PSoC platform consists of many Programmable System-on-chip Controller devices. These devices are designed to replace multiple traditional MCU-based system components with one, low-cost single-chip programmable device. PSoC devices include configurable blocks of analog and digital logic, and programmable interconnects. This architecture enables the user to create customized peripheral configurations that match the requirements of each individual application. Additionally, a fast CPU, flash program memory, SRAM data memory, and configurable I/Os are included in a range of convenient pinouts and packages. The PSoC architecture, as shown in Figure 3-1, consists of four main areas: PSoC Core, digital system, analog system, and system resources. Configurable global busing enables all the device resources to be combined into a complete custom system. The CY8CPLC20 family can have up to five I/O ports that connect to the global digital and analog interconnects, providing access to 16 digital blocks and 12 analog blocks. The PSoC core is a powerful engine that supports a rich feature set. The core includes a CPU, memory, clocks, and configurable GPIO (General Purpose I/O). Figure 3-1. PSoC Core Analog Port 7 Port 6 Port 5 Port 4 Port 3 Port 2 Port 1 Port 0 Drivers SYSTEM BUS Global Analog Interconnect SROM Flash 32K The PSoC device incorporates flexible internal clock generators, including a 24 MHz internal main oscillator (IMO) accurate to 2.5 percent over temperature and voltage. The 24 MHz IMO can also be doubled to 48 MHz for the digital system use. A low power 32 kHz internal low speed oscillator (ILO) is provided for the sleep timer and WDT. If crystal accuracy is desired, the ECO (32.768 kHz external crystal oscillator) is available for use as a real time clock (RTC) and can optionally generate a crystal-accurate 24 MHz system clock using a PLL. When operating the powerline transceiver (PLT) user module, the ECO must be selected to ensure accurate protocol timing. The clocks, together with programmable clock dividers (as a System Resource), provide the flexibility to integrate almost any timing requirement into the PSoC device. PSoC GPIOs provide connection to the CPU, digital, and analog resources of the device. Each pin’s drive mode may be selected from eight options, enabling great flexibility in external interfacing. Every pin also has the capability to generate a system interrupt on high level, low level, and change from last read.

Development Tools PSoC Designer™ is the revolutionary integrated design environment (IDE) that you can use to customize PSoC to meet your specific application requirements. PSoC Designer software accelerates system design and time to market. Develop your applications using a library of precharacterized analog and digital peripherals (called user modules) in a drag-and-drop design environment. Then, customize your design by leveraging the dynamically generated application programming interface (API) libraries of code. Finally, debug and test your designs with the integrated debug environment, including in-circuit emulation and standard software debug features. PSoC Designer includes: ■ Application editor graphical user interface (GUI) for device and user module configuration and dynamic reconfiguration ■ Extensive user module catalog ■ Integrated source-code editor (C and assembly) ■ Free C compiler with no size restrictions or time limits ■ Built-in debugger ■ In-circuit emulation ■ Built-in support for communication interfaces: 2 ❐ Hardware and software I C slaves and masters ❐ Full-speed USB 2.0 ❐ Up to four full-duplex universal asynchronous receiver/transmitters (UARTs), SPI master and slave, and wireless PSoC Designer supports the entire library of PSoC 1 devices and runs on Windows XP, Windows Vista, and Windows 7. PSoC Designer Software Subsystems Design Entry In the chip-level view, choose a base device to work with. Then select different onboard analog and digital components that use the PSoC blocks, which are called user modules. Examples of user modules are analog-to-digital converters (ADCs), digital-to-analog converters (DACs), amplifiers, and filters. Configure the user modules for your chosen application and connect them to each other and to the proper pins. Then generate your project. This prepopulates your project with APIs and libraries that you can use to program your application. The tool also supports easy development of multiple configurations and dynamic reconfiguration. Dynamic reconfiguration makes it possible to change configurations at run time. In essence, this lets you to use more than 100 percent of PSoC's resources for an application. Document Number: 001-48325 Rev. *K Code Generation Tools The code generation tools work seamlessly within the PSoC Designer interface and have been tested with a full range of debugging tools. You can develop your design in C, assembly, or a combination of the two. Assemblers. The assemblers allow you to merge assembly code seamlessly with C code. Link libraries automatically use absolute addressing or are compiled in relative mode, and linked with other software modules to get absolute addressing. C Language Compilers. C language compilers are available that support the PSoC family of devices. The products allow you to create complete C programs for the PSoC family devices. The optimizing C compilers provide all of the features of C, tailored to the PSoC architecture. They come complete with embedded libraries providing port and bus operations, standard keypad and display support, and extended math functionality. Debugger PSoC Designer has a debug environment that provides hardware in-circuit emulation, allowing you to test the program in a physical system while providing an internal view of the PSoC device. Debugger commands allow you to read and program and read and write data memory, and read and write I/O registers. You can read and write CPU registers, set and clear breakpoints, and provide program run, halt, and step control. The debugger also lets you to create a trace buffer of registers and memory locations of interest. Online Help System The online help system displays online, context-sensitive help. Designed for procedural and quick reference, each functional subsystem has its own context-sensitive help. This system also provides tutorials and links to FAQs and an Online Support Forum to aid the designer. In-Circuit Emulator A low-cost, high-functionality in-circuit emulator (ICE) is available for development support. This hardware can program single devices. The emulator consists of a base unit that connects to the PC using a USB port. The base unit is universal and operates with all PSoC devices. Emulation pods for each device family are available separately. The emulation pod takes the place of the PSoC device in the target board and performs full-speed (24 MHz) operation. Page 12 of 56 CY8CPLC20 6. Designing with PSoC Designer The development process for the PSoC device differs from that of a traditional fixed-function microprocessor. The configurable analog and digital hardware blocks give the PSoC architecture a unique flexibility that pays dividends in managing specification change during development and lowering inventory costs. These configurable resources, called PSoC blocks, have the ability to implement a wide variety of user-selectable functions. The PSoC development process is: 1. Select user modules. 2. Configure user modules. 3. Organize and connect. 4. Generate, verify, and debug. Select User Modules PSoC Designer provides a library of prebuilt, pretested hardware peripheral components called “user modules.” User modules make selecting and implementing peripheral devices, both analog and digital, simple. Configure User Modules Each user module that you select establishes the basic register settings that implement the selected function. They also provide parameters and properties that allow you to tailor their precise configuration to your particular application. For example, a PWM User Module configures one or more digital PSoC blocks, one for each eight bits of resolution. Using these parameters, you can establish the pulse width and duty cycle. Configure the parameters and properties to correspond to your chosen application. Enter values directly or by selecting values from drop-down menus. All of the user modules are documented in datasheets that may be viewed directly in PSoC Designer or on the Cypress website. These user module datasheets explain the internal operation of the user module and provide performance specifications. Each datasheet describes the use of each user Document Number: 001-48325 Rev. *K module parameter, and other information that you may need to successfully implement your design. Organize and Connect Build signal chains at the chip level by interconnecting user modules to each other and the I/O pins. Perform the selection, configuration, and routing so that you have complete control over all on-chip resources. Generate, Verify, and Debug When you are ready to test the hardware configuration or move on to developing code for the project, perform the “Generate Configuration Files” step. This causes PSoC Designer to generate source code that automatically configures the device to your specification and provides the software for the system. The generated code provides APIs with high-level functions to control and respond to hardware events at run time, and interrupt service routines that you can adapt as needed. A complete code development environment lets you to develop and customize your applications in C, assembly language, or both. The last step in the development process takes place inside PSoC Designer's Debugger (accessed by clicking the Connect icon). PSoC Designer downloads the HEX image to the ICE where it runs at full-speed. PSoC Designer debugging capabilities rival those of systems costing many times more. In addition to traditional single-step, run-to-breakpoint, and watch-variable features, the debug interface provides a large trace buffer. It lets you to define complex breakpoint events that include monitoring address and data bus values, memory locations, and external signals. Page 13 of 56 CY8CPLC20 ■ 6.1 PLC User Modules Powerline transceiver (PLT) user module (UM) enables data communication over powerlines up to baud rates of 2400 bps. This UM also exposes all the APIs from the network protocol for ease of application development. The UM, when instantiated, provides the user with three implementation modes: ■ FSK Modem Only – This mode enables the user to use the raw FSK modem and build any network protocol or application with the help of the APIs generated by the modem PHY. ■ FSK Modem + Network Stack – This mode enables the user to use the Cypress network protocol for PLC and build any application with the APIs provided by the network protocol. FSK Modem + Network Stack + I2C – This mode enables the user to interface the CY8CPLC20 with any other microcontroller or PSoC device. Users can also split the application between the PLC device and the external microcontroller. If the external microcontroller is a PSoC device, then the I2C UMs can be used to interface it with the PLC device. Figure 6-1 on page 14 shows the starting window for the PLT UM with the three implementation modes from which the user can choose. Figure 6-1. PLT User Module The power consumption estimate of the CY8CPLC20 chip with the PLT User Module loaded along with the other User Modules can be determined using the application note AN54416 titled “Using CY8CPLC20 in Powerline Communication (PLC) Applications” at http://www.cypress.com. 1.

Or when devices are cascaded in width, the slave device is the one that allows another device to control the timing of data exchanges between the cascaded devices and an external interface. The controlling device is called the master device. SRAM An acronym for static random access memory. A memory device where you can store and retrieve data at a high rate of speed. The term static is used because, after a value is loaded into an SRAM cell, it remains unchanged until it is explicitly altered or until power is removed from the device. SROM An acronym for supervisory read only memory. The SROM holds code that is used to boot the device, calibrate circuitry, and perform Flash operations. The functions of the SROM may be accessed in normal user code, operating from Flash. stop bit A signal following a character or block that prepares the receiving device to receive the next character or block. synchronous 1. A signal whose data is not acknowledged or acted upon until the next active edge of a clock signal. 2. A system whose operation is synchronized by a clock signal. tri-state A function whose output can adopt three states: 0, 1, and Z (high-impedance). The function does not drive any value in the Z state and, in many respects, may be considered to be disconnected from the rest of the circuit, allowing another output to drive the same net. UART A UART or universal asynchronous receiver-transmitter translates between parallel bits of data and serial bits. user modules Pre-build, pre-tested hardware/firmware peripheral functions that take care of managing and configuring the lower level Analog and Digital PSoC Blocks. User Modules also provide high level API (Application Programming Interface) for the peripheral function. user space The bank 0 space of the register map. The registers in this bank are more likely to be modified during normal program execution and not just during initialization. Registers in bank 1 are most likely to be modified only during the initialization phase of the program. VDD A name for a power net meaning "voltage drain." The most positive power supply signal. Usually 5 V or 3.3 V. VSS A name for a power net meaning "voltage source." The most negative power supply signal. watchdog timer A timer that must be serviced periodically. If it is not serviced, the CPU resets after a specified period of time. Document Number: 001-48325 Rev. *K Page 54 of 56 CY8CPLC20 16.
