" Building on the company’s safety heritage and expertise, Freescale’s SafeAssure functional safety
program enables system designers to develop with confidence and more efficiently achieve their
system-level design goals and compliance with the IEC 61508 and ISO 26262 requirements.
Freescale’s functional safety approach covers four key areas: Safety Process, Safety Hardware,
Safety Software and Safety Support.
Functional safety requirements begin with the way a company designs and implements a
functional safety solution—the Safety Process. Freescale has made functional safety an
integral part of its product development process to align to the rigorous requirements of IEC
61508 and ISO 26262. In addition, select Freescale products are being defined and designed
from the ground up to comply with the standards, with safety analysis done at each step of
the development process and additional confirmation measures taken to help ensure safety
requirements are fully met.
Freescale’s Safety Hardware concept focuses on detecting and mitigating random hardware
failures. This is achieved through built-in safety features, including self-testing, monitoring and
hardware-based redundancy in Freescale MCUs, analog and power management integrated
circuits (ICs) and sensors. Freescale’s analog automotive solutions provide additional functionality
(such as checking MCU timing, voltages and error management) that helps improve system
robustness and simplify electronic control unit designs. Freescale’s Qorivva 56xx automotive
MCUs and PXS family of industrial MCUs based on Power Architecture technology are designed
specifically to address the requirements of the IEC 61508 and ISO 26262 safety standards. A
number of devices in this family are already sampling, with some in full production. The lead
product in the automotive family, the MPC564xL MCU, targets steering and braking applications
and features a dual-core architecture that can be operated in lockstep mode. The PXS20 device
is leading the way in the industrial market, targeting various industrial functional safety applications
including industrial automation and motor control."
