Freescale expands Kinetis with $0.79 MCUs
Freescale Semiconductor has broadened the range of its Kinetis microcontrollers with the release of the second generation devices that start at $0.79 for 10ku/year—said to be the industry's most inexpensive Cortex M4 based MCU devices with floating point unit reaching 100MHz with 64KB of flash.
The K series MCUs has increased onboard SRAM to address customer demand for more memory when adding features such as connectivity and richer human-machine-interfaces. Lower overall BOM costs come from features such as USB with crystal-less functionality for wearables, gaming, IoT data concentrators and end nodes, point-of-sale systems, smart-grid infrastructure, home automation products, and factory automation systems.
The company has also launched a development support to complement the processing enhancements of the Kinetis K series.
The Kinetis SDK is a comprehensive software framework available initially for the K series MCUs, but planned for future availability across the entire portfolio for developing applications based on Kinetis. The SDK incorporates hardware abstraction layers, RTOS adapters, peripheral drivers, libraries, middleware, utilities, and usage examples.
The Freescale Processor Expert Software helps to create, configure, and generate software and drivers for Freescale microcontrollers. and the bootloader software for Kinetis MCUs which enables in-system Flash programming over a serial connection and supports erase, program and verification capabilities.
Meanwhile, an mbed-enabled, low-cost FRDM-K64F Freescale Freedom development platform is compatible with the broad Arduino hardware ecosystem for Kinetis L series and K series MCUs.
With the K0+ devices—as expansion to the existing K1x, K2x, and K6x MCUs—the Kinetis portfolio now delivers up to 180MHz of performance, a floating point unit with 8KB I/D cache, 2MB Flash and 256KB SRAM. The portfolio includes more than 900 devices (600 Kinetis K series MCUs), providing customers a vast selection of software and hardware compatible products from which to choose.
A number of the new Kinetis K series MCUs based on ARM Cortex-M4, including the Kinetis K63, K64, K24, K22, K21, K12 and K11 MCUs are already in production today, with new Kinetis K22 derivatives and K02 MCUs sampling now, and even more devices planned for later this year. Customers can start developing today with the variety of available Tower System modules and the newly launched Freescale Freedom development platform, the FRDM-K64F.
