Freescale Semiconductor recently rolled out its 5V 32bit MCUs built on the ARM Cortex-M0+ processor. The new Kinetis E series MCUs feature electromagnetic noise immunity for systems that traditionally use 8 and 16bit MCUs, such as white goods and industrial applications, while providing high efficiency and optimal code density.

The Kinetis E series can be used in dishwashers, refrigerators, home and building control systems, motor control fans, industrial converters and other equipment commonly operating in high-noise environments. Leveraging a robust design and 32bit processing capabilities, systems designers can use a single device instead of the multiple MCUs previously required. In addition, large-pitch packaging options and high electrostatic discharge protection performance can enable single-layer board designs and reduce the need for additional circuit protection components, leading to lower system cost.

"32bit MCUs have been associated with lower voltage operation and considered unreliable in electromagnetically harsh environments such as factories or even many households," said Brandon Tolany, Freescale's vice president. "Kinetis E series MCUs break new ground by combining low cost and high performance with advanced electromagnetic compatibility (EMC) and electrostatic discharge (ESD) protection features designed to support compliance with industrial-grade reliability and temperature requirements."

The company offers both hardware features and pre-certified, fault-tolerant software routines engineered to help customers meet the IEC 60730 Class B safety standard for household appliances, which is mandatory in European markets.
