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

knowledge, would be dishonest and possibly illegal. Neither Cypress nor any other semiconductor manufacturer can

guarantee the security of their code. Code protection does not mean that we are guaranteeing the product as ‘unbreakable’.

Cypress is willing to work with the customer who is concerned about the integrity of their code. Code protection is constantly

evolving. We at Cypress are committed to continuously improving the code protection features of our products.

1. Introduction

The Cypress Semiconductor EZ-USB®NX2LP-Flex™ Controller chip (CY7C68033) is a

programmable USB NAND controller based on the FX2LP (CY7C68013A) silicon. The NX2LP-Flex

architecture enables USB data transfer rates of over 53 MB for every second. This is the maximum

allowable USB 2.0 bandwidth, while still using a low-cost 8051 microcontroller in a small 56-pin QFN

package While both CY7C68033 and CY7C68034 are functionally similar, the latter is more

appropriate for battery-powered applications because of its low standby power consumption.

The CY3686 EZ-USB NX2LP-Flex Development Kit (DVK) is provided to customers for evaluating

and developing NAND Flash USB mass storage applications using the NX2LP-Flex controller. The

CY3686 NX2LP-Flex DVK is a combination of two development platforms:

■The CY3684 EZ-USB FX2LP-DVK, based on Cypress's most popular USB 2.0 general purpose

microcontroller, the EZ-USB FX2LP

■The NX2LP-Flex development board, based on Cypress's NAND flash controller EZ-USB

NX2LP-Flex

This enables users to integrate their custom application with NAND flash solutions.

This chapter gives an overview of the DVK. Chapter 2 describes the installation of the CY3686

NX2LP-Flex DVK kit and drivers. Chapter 3 describes the utilities provided with the kit and firmware

debugging with Keil uVision. Chapter 4 describes the kit hardware. Chapter 5 describes the NX2LP

NAND Programming utility. The Appendix chapter describes firmware design notes, USB Mass

Storage testing, handling SOP sockets, schematics and layout, and frequently asked questions

associated with the CY3686 NX2LP-Flex DVK.

1.1 CY3686 EZ-USB NX2LP-Flex DVK Features

This kit provides:

■NAND flash firmware source code with the following features:

❐512-page, 2K-page, and 4K-page NAND type support

❐Removable/unremovable device configuration

❐USB BULK only mass storage device class support

❐Windows boot support

❐Autorun support

❐2-NAND chips select and 8-NAND chips select support

6 CY3686 EZ-USB® NX2LP-Flex™ Development Kit Guide, Doc. # 001-61287 Rev. *B

Introduction

■NAND flash manufacturing utility programs

❐NandMfg.exe (NAND flash programming tool)

❐BldNx2.exe (Build configuration file)

■GPIF designer tool

■MAC OS 9.x drivers available at http://www.cypress.com/?rID=14396

1.2 CY3686 EZ-USB NX2LP-Flex DVK Contents

The development kit includes:

■EZ-USB advanced development board (FX2LP base board)

■EZ-USB prototyping board ("Breadboard")

■NX2LP-Flex board populated with two NAND flash devices

■USB cable

■RS-232 cable

■CY7C68033 sample chips

■NAND manufacturing utility

■CY3686 firmware and BldNx2 utility

■GPIF Designer

■Kit CD/DVD with documentation

1.3 System Requirements

The CY3686 EZ-USB NX2LP-Flex DVK has the following system requirements:

■Microsoft Windows XP/Windows Vista/Windows 7

■Microsoft .NET Framework v2.0 or later

■Administrative privileges on the system

■64 MB RAM (256 MB recommended)

■Pentium IV-class PC (1 GHz or higher recommended)

■Super VGA display (resolution 800 × 600 or higher)

■USB Host Controller (full-speed or high-speed)

The NAND development tools (such as, NANDMfg.exe, BldNx2.exe, and so on) are supported on

Windows XP, Windows Vista, and Windows 7 and not on Mac or Linux OS. However, after the NAND

flash is programmed, the Cypress EZ-USB NX2LP development board and the EZ-USB NX2LP

NAND flash Controller operate in a Mac and Linux environment if the OS supports USB mass

storage devices.
