Austin, Tex. − Freescale Semiconductor has claimed the industry's first 5-V 32-bit MCUs built on the ARM Cortex-M0+ processor. The Kinetis E series MCUs feature electromagnetic noise immunity for systems that traditionally use 8- and 16-bit MCUs, such as white goods and industrial applications. Target applications include dishwashers, refrigerators, home and building control systems, motor control fans, industrial converters and other equipment that operate in high-noise environments.
The Kinetis E series enables system designers to use a single device instead of the multiple MCUs previously required, said Freescale. In addition, large-pitch packaging options and high electrostatic discharge (ESD) protection performance can enable single-layer board designs and reduce the need for additional circuit protection components for lower system cost, added the company.
Freescale offers hardware features (built into Kinetis E series MCUs) and pre-certified, fault-tolerant software routines to help customers meet the IEC 60730 Class B safety standard for household appliances, which is mandatory in European markets.
Key features include:
- Flash, RAM, register, watchdog and clock tests
- 2.7V to 5.5V and across -40 degrees C to +105 degrees C ambient temperature range
- ARM Cortex-M0+ core running up to 20 MHz
- Single-cycle 32-bit x 32-bit multiplier
- Single-cycle I/O access port
- Up to 64 KB flash memory
- 256 B EEPROM
- Up to 4 KB RAM
"It's impressive to see a 32-bit MCU family at these price points for this type of environment," said Tony Massimini, chief of technology at Semico Research, in a statement. "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."
Support for the Kinetis E series MCUs includes the FRDM-KE02Z Freescale Freedom development platform, Processor Expert software, as well as a software development kit that provides easy access to sample software libraries. The development platform is designed to speed up evaluation and prototyping with Freescale MCUs. ARM ecosystem support includes 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 optimal power efficiency CoreMark/mA.
Pricing: Suggested resale pricing for the KE02 MCU family ranges from 78 cents to $1.13 in quantities of 10,000. The FRDM-KE02Z Freescale Freedom development platform is priced at $12.95.
