Safety Manual for C2000™ MCUs in IEC60730 Safety
Applications
1 Introduction
You, as a system and equipment manufacturer or designer, are responsible to ensure that your systems
(and any Texas Instruments hardware or software components incorporated in your systems) meet all
applicable safety, regulatory, and system-level performance requirements. All application and safety
related information in this document (including application descriptions, suggested safety measures,
suggested TI products, and other materials) is provided for reference only. You understand and agree that
your use of TI components in safety critical applications is entirely at your risk, and that you (as buyer)
agree to defend, indemnify, and hold harmless TI from any and all damages, claims, suits, or expense
resulting from such use.
This document is a safety manual for the Texas Instruments C2000 32-bit real time C2000™
microcontrollers product family. This document introduces TI’s C2000 family of controllers and its
subsystem-based architecture that matches most real-time control systems. Its inherent safety features
could enable existing and emerging systems that require IEC60730 and IEC60335 or UL1998 safety
compliance.
1.1 About This Document
This safety manual provides information needed by system developers to assist in the creation of a
IEC60730 class of safety system using a C2000 microcontroller (MCU). This document contains:
• An overview of C2000 MCU - Piccolo™ and Delfino™ MCU product architecture
• An overview of the development process utilized to reduce systematic failures
• An overview of the safety architecture for management of random failures
• The details of architecture partitions, implemented safety mechanisms, and recommended usage
• Software design and development process
It is expected that the user of this document should have a general familiarity with the C2000 product
family. More information can be found at http://www.ti.com/C2000. This document is intended to be used
in conjunction with the device-specific data sheets, technical reference manuals, and other documentation
for the products under development. This partition of technical content is intended to simplify development,
reduce duplication of content, and avoid confusion as compared to the definition of safety manual
referenced in any of the IEC safety standards.
IEC60730, IEC60335 and UL1998 specification addresses safety in appliances and equipment’s that uses
microelectronic hardware and its related software. All these standards reference similar safety functions
addressing appliances or industrial equipment. Throughout this document IEC60730 will be the common
name used for this safety standard, unless called separately. This document will cover Class B and
Class1 level of safety mentioned in these specifications. For this release of this document, all references
are applicable IEC60730-1: 2010 Class B and UL1998:2008 Class 1 standards.
