Developing automotive systems under the conditions of ISO 26262 definitely is no joy ride. Reading the specs alone can be an ordeal, and testing for compliance is even worse. It's a good thing that tool manufacturers increasingly offer certification services. Freescale now takes this one step further.
The »Qorivva MPC574xP« aCU and MC33906/7/8 SBC families are designed from the ground up in order to allow system manufacturers to achieve system compliance with functional safety standards by providing integrated safety architectures in hardware, a ccompanying safety software, and a support infrastructure that helps reduce development time.
The Freescale SafeAssure program includes various MCUs, sensors and analog ICs, as well as support including training, safety documentation and technical support for functional safety application design.
"Our system-level approach helps developers reduce the complexity of achieving compliance with safety standards while building advanced safety performance into their systems," said Gavin Woods, vice president and general manager of Freescale’s Analog & Mixed-Signal Products Division. "Our new generation of SBCs along with the latest Qorivva MCU are backed by the Freescale SafeAssure program and enable our customers to meet their system-level functional safety goals."
The Qorivva MPC574xP MCU provides the performance and features needed to address functional safety requirements up to the ISO 26262 ASIL D level. Operating up to 180 MHz, the Qorivva MCU is built on a 55 nm process with an integrated safety architecture, dual-core delayed lock step and additional on-chip redundancy. It can operate in extreme operating environments, such as electric power steering systems, that require a junction temperature of up to 165 degrees C.
By integrating many features into one safety platform, the MPC574xP offers approximately twice the memory, performance and motor control capabilities of previous Freescale products. And, pin compatibility means existing Freescale MCU customers can upgrade with only minor hardware and software changes, speeding time-to-market and reducing the overall development cycle. This device builds on Freescale’s legacy of shipping dual-core lockstep MCUs to the automotive market for more than a decade.
The SBC devices provide power to MCUs and other system loads and optimize energy consumption through low-power saving modes. The devices also contain CAN and LIN physical layers compliant with the ISO 11898-2-5 and LIN 2.1/J2602-2 standards, safety measures and a serial peripheral interface to allow control and diagnostic with the MCU.
The pin-compatible MC33906/7/8 family is the latest generation of Freescale SBC solutions that includes DC/DC switching regulators to optimize energy efficiency. An optional boost mode keeps the system available during engine cranking pulses. In addition, ultra-low-power modes are designed to drastically reduce current consumption and optimize wake-up times. As with previous generations, the new SBCs are designed to meet the latest automotive OEM requirements for electromagnetic compatibility.
These SBCs are part of the Freescale Energy-Efficient Solutions program, which means they are designed to offer customers assurance that Freescale has employed the right combination of technologies and techniques to achieve optimal energy savings as relevant to a particular application space. The mark stands for Freescale’s technology expertise in delivering products optimized for high performance within the constrained energy and power budgets of embedded environments.
