Cypress has introduced the first truly programmable solution for data communication over power lines.

Using the programmable analogue and digital resources of Cypress's PSoC programmable system-on-a-chip architecture, the new Cypress Powerline Communication (PLC) solution integrates multiple functions beyond communication, such as power measurement, system management and LCD drive.

In addition to its flexibility and integration, the new solution offers reliability with greater than 97% packet success rates without retries and 100% success rates with retries built into the solution's coding. It offers the flexibility to communicate over high-voltage and low-voltage power lines for lighting and industrial control, home automation, automatic meter reading and smart energy management applications.

Whereas existing solutions require external microcontrollers and filters, the Cypress PLC solution integrates a Frequency-Shift Key (FSK) PHY modem, network protocol and application code with the programmable analogue and digital blocks and microcontroller of the PSoC architecture. This combination provides a single hardware platform for multiple applications, reducing BOM cost, board size and chip count while improving manufacturability. Cypress offers reference designs for high-voltage (110V - 240V AC) and low-voltage (12V - 24V AC/DC) coupling circuits based on boards compliant with Federal Communications Commission (FCC) and European Committee for Electrotechnical Standardization (CENELEC) standards.

"Our lead customers have raved about the unparalleled reliability of our PLC solution, and the versatility it offers with PSoC," said Dinesh Ramanathan, Executive Vice President of the Data Communication Division at Cypress. "Our PowerPSoC line has helped us build strong expertise with lighting and other control applications, further adding value to our complete PLC solution for customers."

The PowerPSoC family offers the industry's first single-chip solution to control and drive high-power LEDs. The Cypress PLC solution integrates LED driving support.

Additional features and benefits of the PLC solution include:
• Support for bidirectional half-duplex communication
• Flexibility to use complete solution (PHY, Protocol and Application code) or just pieces of solution (PHY and Protocol or PHY only)
• Variable baud rates up to 2400bps
• Onboard power supply derives power from the power line bus

The Cypress PLC family includes a cost-optimised fixed-function device with an I2C interface (CY8CPLC10), programmable PSoC-based devices (CY8CPLC20), and programmable PSoC-based devices optimised for LED support (CY8CLED16P01). The CY8CPLC10 device is available in a 28-pin SSOP package, while the CY8CPLC20 and CY8CLED16P01 devices come in 28-pin SSOP, 48-pin QFN and 100-pin TQFP packages. All of the devices are currently in production.

Cypress also offers multiple evaluation and development kits:
• The CY3272 High Voltage Powerline Communication Evaluation Kit and CY3273 Low Voltage Powerline Communication Evaluation kit are currently available. Each kit is compliant with FCC and CENELEC standards and includes an evaluation board, quick start guide, multiple cables, a USB cable, a 12V AC power adapter and a CD with test software, datasheets, a user guide, an application note, schematics and Gerber files
• The CY3274 Programmable High Voltage Powerline Communication Development Kit and CY3275 Programmable Low Voltage Powerline Communication Development Kit enables system design using CY8CPLC20 devices. The CY3276 Programmable High Voltage Powerline Communication Development Kit and CY3277 Programmable Low Voltage Powerline Communication Development Kit are targeted for lighting application system design using CY8CLED16P01 devices.

PSoC devices employ a highly configurable system-on-chip architecture for embedded control design, offering a flash-based equivalent of a field-programmable ASIC without lead-time or NRE penalties. PSoC devices integrate configurable analogue and digital circuits, controlled by an on-chip microcontroller, providing both enhanced design revision capability and component count savings. A single PSoC device can integrate as many as 100 peripheral functions saving customers design time, board space and power consumption while improving system quality and reducing system cost.

The new PSoC 3 and PSoC 5 architectures include high-precision programmable analogue capability (up to 20bit resolution for an Analogue to Digital Converter) and expanded programmable digital resources integrated with powerful, industry-standard MCU cores and ample memory and communications peripherals. PSoC 3 devices are based on a high-performance 8bit 8051 processor, while PSoC 5 devices include a powerful 32bit ARM Cortex-M3 processor. The products provide designers with a seamless, programmable design platform, enabling easy migration from 8bits to 32bits.
