SANTA CLARA, Calif. -- August 26, 2014

Renesas Electronics Corporation, a premier supplier of advanced semiconductor
solutions, today announced that it has obtained IEC 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

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/EC^1 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 sensors.

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-related 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, and flash ROM. The self-diagnostic software uses fault
simulation^2 to obtain the diagnostic yields of CPU-related diagnostics. This
provides a clear basis for diagnostic yields and contributes to more efficient

(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 TÜV 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 TÜV-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 machinery products.

^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.
