16-bit MCU and DSC Programmer’s Reference Manual High-Performance Microcontrollers (MCU) and Digital Signal Controllers (DSC) 本手册《dsPIC30F Programmer manual》是关于dsPIC30F系列高性能微控制器（MCU）和数字信号控制器（DSC）的程序员参考手册，由Microchip Technology Inc.在2009年发布。从提供的文件内容来看，手册中涉及了代码保护特征、产品安全和合规性相关的知识。手册中提到了Microchip产品的代码保护功能。Microchip的产品在其数据表中规定了相关规格，并声称其产品系列在市场上是最安全的产品之一，这指的是在正常使用和正常条件下使用的安全性。然而，也提醒了存在不诚实甚至是非法的方法来破坏代码保护功能。如果有人试图通过非授权的方式访问软件或其他受版权保护的作品，可能会违反《数字千年版权法案》。这强调了代码保护是一个持续发展的领域，并且Microchip承诺会不断地改进其产品的代码保护特性。此外，手册还提到，Microchip不能保证其产品的安全性，因为代码保护并不意味着产品是“无法破解”的。这表明即使拥有先进的代码保护措施，也没有任何半导体制造商能保证其产品的绝对安全性。用户应当了解，试图破解代码保护功能可能会构成违法行为。手册还提供了设备应用等信息，这些信息仅为了方便用户参考，可能会被后续的更新所替代。因此，用户有责任确保他们的应用符合自身的要求和规格。在法律声明方面，Microchip明确表示不对所提供的信息做出任何形式的声明或保证，无论是明示的、暗示的、书面的、口头的、法定的还是其他的。这些信息包括但不限于产品的条件、质量、性能、适用性或目的适合性。这意味着，如果由于信息的使用而产生的任何责任和损失，Microchip将不承担责任。手册还提到，如果用户将Microchip的产品应用于生命支持和/或安全系统中，将完全是购买者的责任。购买者需要对由此带来的任何损害进行辩护、赔偿，并保证Microchip免受损害。本手册是一份关于dsPIC30F系列微控制器和数字信号控制器的程序员参考指南，不仅提供了关于产品编程的具体技术信息，而且涉及了代码保护、产品安全、合规性等多方面的内容。这些内容对于从事微控制器和数字信号控制器相关工作的开发者和工程师具有重要的参考价值。

Note the following details of the code protection feature on Microchip devices:

• Microchip products meet the specification contained in their particular Microchip Data Sheet.

• Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the

intended manner and under normal conditions.

• There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our

knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data

Sheets. Most likely, the person doing so is engaged in theft of intellectual property.

• Microchip is willing to work with the customer who is concerned about the integrity of their code.

• Neither Microchip 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.”

Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our

products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts

allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.

Microchip received ISO/TS-16949:2002 certification for its worldwide

headquarters, design and wafer fabrication facilities in Chandler and

Tempe, Arizona; Gresham, Oregon and design centers in California

and India. The Company’s quality system processes and procedures

are for its PIC

MCUs and dsPIC

DSCs, KEELOQ

code hopping

devices, Serial EEPROMs, microperipherals, nonvolatile memory and

analog products. In addition, Microchip’s quality system for the design

and manufacture of development systems is ISO 9001:2000 certified.
