Freescale integrates support for new analog system basis chips

Intending to reduce the cost and complexity of designing applications required to meet functional safety standards, Freescale Semiconductor is reportedly helping automotive and industrial system designers. The company has announced new system basis chips (SBCs) that provide support for stringent system-level functional safety integrated with a high efficiency DC/DC switching regulator for reducing overall energy consumption.

Developed in accordance with the key functional safety requirements, Freescale’s new MC33907and MC33908 SBCs work seamlessly with 32-bit microcontrollers (MCUs) like Freescale’s Qorivva series devices to provide a scalable power supply solution that combines power management and communications with integrated functional safety for a broad range of power segmentation architectures.

Featuring the efficiency of a dual DC/DC switching regulator architecture and unique, low-voltage operation down to 2.7 V supply, the MC33907 and MC33908 products supply power to microcontrollers and other system loads while maintaining system operation during power brown-out events such as during an automotive cranking pulse. Ultra-low power modes and innovative wake-up capabilities reduce system quiescent current down to 30 µA, limiting system standby energy consumption and battery discharge. The devices’ configurable voltage regulator capabilities enable design of scalable platform solutions optimized for 32-bit MCUs supporting functional safety certifications across multiple vehicles or industrial applications.

“Achieving functional safety compliance can be difficult and costly. Freescale makes it quicker and easier to achieve compliance with these new system basis chips, which are designed to meet ISO 26262 ASIL D – the most stringent functional safety requirement, as well as the latest automotive OEM requirements for ESD and electromagnetic compatibility,” said James Bates, General Manager & Senior Vice-President of Freescale’s Analog and Sensors Group.

The MC33907 and MC33908 SBCs are available now for a suggested resale price starting at US$2.49 and US$2.55, respectively in 10,000-piece quantities. Please contact Freescale Sales for additional quantities.
