Renesas Electronics Introduces an IEC 61508 T�V-Certified RX631, 63N Safety Package to Accelerate Implementation of Safety Systems for Industrial Equipment
SANTA CLARA, Calif. --(Business Wire)--
Renesas Electronics Corporation, a premier supplier of advanced
semiconductor solutions, today announced that it has obtained IEC (News - Alert) 61508
(Functional Safety) certification for the RX631, RX63N Safety Package,
featuring a robust self-diagnostic software and a safety manual for
microcontrollers (MCUs) necessary to implement functional safety in
industrial equipment. An RX631, RX63N Safety Solution Evaluation Kit
will be available in September 2014, providing a hardware evaluation
board with the RX63N
MCU, the evaluation version of the self-diagnostic software library, and
a Users Guide.
"Renesas is committed to the quality and the inherent functional safety
of our devices, and we understand the complexity that comes with
stringent standards like the IEC 61508," said Ritesh Tyagi, vice
president of marketing, Renesas Electronics America. "Our Functional
Safety Package solution provides customers one less thing to worry
about, reducing their risk in certifying their own safety solutions and
allowing them to focus on their core areas of expertise."
Functional safety has become a growing reality for factories, equipment
manufacturers, and automation OEMs to reduce economic losses due to
equipment failures, production losses, and more importantly threats to
personnel safety. The European Machinery Directive 2006/42/EC1
mandates support for functional safety, and efforts to bring relevant
industrial equipment into compliance with functional safety standards
such as IEC 61508 have been moving forward. Functional safety is now
implemented on multiple industrial equipment such as industrial motor
drives, control equipment, industrial networking equipment as well as
Compliance with the IEC 61508 functional safety standard not only
requires system designers to perform tasks referred to as safety
analysis, such as failure analysis of safety-related hardware and study
of failure diagnostic methods and their diagnostic yields, but also to
meet defined regulations aimed at reducing specification and design
errors in the development process of safety-rlated systems that can
result in malfunctions. In particular, maintaining conformance at all
stages of the software development process is a key issue.
Of the tasks that need to be performed by system developers, such as
safety analysis and study of failure diagnostic methods and diagnostic
yields, Renesas has already carried out the aspects related to the MCU.
For the testing process, Renesas leveraged IAR Systems' IAR Embedded
Workbench for RX certified for Functional Safety, which fulfilled the
requirement for proof of tools safety certification. It offers a
complete and high-performance C/C++compiler and debugger toolchain
together with comprehensive documentation. In addition, the Safety
Manual includes the vital information such as FIT rates and SFF (Safe
Failure Fraction) computation that can be passed on to a certifying body
to reduce complexity in conformance.
Key features of the RX631, RX63N Functional Safety Package Solution:
(1) Self-diagnostic software library and safety
manual for RX631 and RX63N 32-bit MCUs
The safety manual contains the results of safety analysis performed on
each internal functional block of the MCU, and the self-diagnostic
software library covers the CPU, RAM (News - Alert), and flash ROM. The self-diagnostic
software uses fault simulation2 to obtain the diagnostic
yields of CPU-related diagnostics. This provides a clear basis for
diagnostic yields and contributes to more efficient development.
(2) IEC 61508-certified self-diagnostic software
library for a simplified software development process
The self-diagnostic software library for the RX631 and RX63N MCUs has
been certified as compliant with IEC 61508 SIL3 by the international
certification authority T�V Rheinland of Germany. When installing this
software, the customer can omit the usual verification of conformance of
the software development process required by the IEC 61508 standard.
(3) RX631, RX63N Safety Solution Evaluation Kit
The RX631, RX63N Safety Solution Evaluation Kit includes an MCU
self-diagnostic software library, an evaluation board with the RX63N MCU
installed on it, as well as the T�V-certified Functional Safety version
of IAR Embedded Workbench and compiler for RX from IAR Systems. This
will enable system designers to get started immediately with diagnostic
software performance evaluation and initial system consideration.
With the new Safety Package, Renesas continues to deliver on its
commitment to support customers in functional safety system development,
offering more functional safety solutions for the industrial field,
including a stronger lineup with support for industrial MCUs such as the
high-performance, low-power RX100 Series.
1 European Directive on Machinery: A unified standard adopted
by the European Union that covers the distribution of industrial
2 Fault simulation: An evaluation method that uses a fault
simulator to determine the rate at which the self-diagnostic mechanism
can detect hypothetical failures.
