Flash Code Protection

Cypress products meet the specifications contained in their particular Cypress PSoC Data Sheets. Cypress believes that its

family of PSoC products is one of the most secure families of its kind on the market today, regardless of how they are used.

There may be methods, unknown to Cypress, that can breach the code protection features. Any of these methods, to our

1. Introduction

1.1 Safety Precautions

■Use the board with expert technical supervision. There is high voltage (110-V, 240-V AC) power

on the board.

■Accidental human contact with high voltage is dangerous.

■The capacitors on the board can be energized even after disconnecting the board from the main

power supply. Be careful not to touch any parts on the board immediately after you disconnect the

main power supply.

■Safety plastic casing is provided on the top of the high voltage section. Do not touch the

protected area during live operation for debugging, probing, or for any other purpose.

Cypress bears no responsibility for any consequences that may result from the improper or

hazardous use of this board.

1.2 Using the PLC Kit

Cypress’s Powerline Communication Solution (PLC) makes it possible to transmit command and

control data over high voltage and low voltage powerlines. This solution is developed for low

bandwidth powerline communication.

The CY3274 PLC high voltage (HV) PLC development kit provides the capability to develop an appli-

cation on the Cypress CY8CPLC20 device that can transmit and receive data over high voltage

(110 V to 240 V AC) powerlines.

■Chapter 1 provides a brief overview of the Cypress PLC solution. It describes the contents of the

CY3274 development kits and lists special features of the kit.

■Chapter 2 gives the functional overview of the PLC board and describes the operating procedure

of PLC HV board. It provides a high level hardware description of the board.

■The Appendix contains the schematics, layout, and bill of materials.

1.3 The Cypress PLC Solution

Powerlines are available everywhere in the world. This makes them one of the most widely available

communication media. The pervasiveness of powerlines also makes it difficult to predict their

characteristics and noise. Because of the variability of powerline quality, 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

powerlines.

CAUTION: High Voltage (Risk of Electric Shock)

Extreme care is necessary when you work with powerline communication

equipment.

Use caution when using power supplies or power related equipment.

Introduction

The key features of the Cypress PLC solution are:

■An integrated powerline PHY modem with optimized filters and amplifiers that work with rugged

high and 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 FSK modem

■Power amplification and coupling circuits

Figure 1-1. Cypress PLC Solution Block Diagram

The powerline network protocol layer and the physical layer FSK modem are implemented on the

CY8CPLC20 chip. The chip also contains a PSoC core in addition to the PLC core. The CY3274

board contains the CY8CPLC20 device along with the power amplification and coupling circuit for

communicating on high voltage (110-240 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.

Introduction

The network protocol layer allows for the addressing of multiple nodes on the network. This enables

point-to-multipoint communication. The protocol layer also provides a defined packet structure for

transmitting data packets from one node to the other as well as error detection and packet retransmit

functionalities. The chip contains a PSoC core in addition to the PLC core. The PSoC core includes

configurable blocks of analog and digital logic, and programmable interconnects. This architecture

enables you to create customized peripheral configurations that match the requirements of each

individual application. A fast CPU, flash program memory, SRAM data memory, and configurable

I/Os are also included.

A two-node system level diagram is shown in Figure 1-2. To evaluate this kit, follow the steps in the

quick start guide, which is provided in the kit.

Note To evaluate this kit, a second high voltage PLC kit is required. The compatible kits are CY3274

(this kit) and CY3272 High Voltage PLC Evaluation Kit, with EZ-Color. For information on these kits,

visit http://www.cypress.com/go/CY3274 and http://www.cypress.com/go/CY3272.
