Freescale Semiconductor has today introduced the industry’s first 5V 32-bit microcontrollers built on the ARM Cortex-M0+ processor. Providing high efficiency and optimal code density, the new Kinetis E series MCUs feature electromagnetic noise immunity for systems that traditionally use 8- and 16-bit MCUs (white goods and industrial applications).
Intended applications for the new Kinetis E Series MCUs include dishwashers, refrigerators, home and building control systems, motor control fans, industrial converters and other equipment commonly operating in high-noise environments. Incorporating 32-bit processing capabilities and a highly robust design, the Kinetis E series MCUs can be used in place of the multiple MCUs previously required by system designers. Reducing the need for additional circuit protection, the new devices feature large-pitch packaging options and high electrostatic discharge protection performance. This enables single-layer board designs, reducing total system cost.
Freescale offers both hardware features (built into Kinetis E series MCUs) 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.
“Historically, 32-bit MCUs have been associated with lower voltage operation and considered unreliable in electromagnetically harsh environments such as factories or even many households. Kinetis E series MCUs break new ground by combining low cost and high performance with advanced electromagnetic compatibility and electrostatic discharge protection features designed to support compliance with industrial-grade reliability and temperature requirements,” comments Brandon Tolany, vice president of marketing and business development for Freescale’s MCU business.
Kinetis KE02 MCU features
Tony Massimini, chief of technology at Semico Research, commented “It’s impressive to see a 32-bit MCU family at these price points for this type of environment. The Kinetis E series MCUs allow customers to step up performance and leverage more advanced development tools and the extensive ecosystem surrounding the ARM Cortex M0+ core. As we see the market shifting to 32-bit solutions, the robustness of these 5V MCUs should even make it possible for systems challenged by signal-to-noise concerns to make the switch.”
Design freedom with world-class software support
Kinetis E series MCUs feature world-class development support, including the FRDM-KE02Z Freescale Freedom development platform, Processor Expert software, as well as a software development kit providing easy access to sample software libraries. The low-cost Freescale Freedom development platform makes it easy for customers to rapidly evaluate and prototype with Freescale MCUs. Kinetis E series MCUs also benefit from broad ARM ecosystem support including off-the-shelf software, tools and training, as well as partner-developed solutions, such as IAR Embedded Workbench and the Keil MDK-ARM Microcontroller Development Kit. Additional development resources include middleware and software libraries with high performance and optimal power efficiency CoreMark/mA.
Availability and pricing
The first Kinetis E series device, the 64-pin QFP version of the KE02, is available now. Suggested resale pricing for the KE02 MCU family in 10K unit quantities ranges from 78 cents to $1.13 (USD). The FRDM-KE02Z Freescale Freedom development platform is available now for $12.95 (USD).
