Freescale Semiconductor has announced a line-up of low cost ARM Cortex M4 floating point MCUs. The portfolio delivers up to 180MHz of performance, a floating point unit with 8KB I/D cache, 2MB Flash and 256KB SRAM.

Alongside the latest Kinetis K0+ family and development boards, the second generation of Kinetis devices also expands the existing K1x, K2x and K6x MCU families with over 600 devices in the K range and 900 in total.

The devices start at prices as low as $0.79 for 10ku/year, which Freescale said is the industry's lowest priced Cortex-M4 based MCU with floating point unit reaching 100MHz with 64KB of Flash.

Freescale has also launched an mbed-enabled, low-cost FRDM-K64F Freescale Freedom development platform that is compatible with the broad Arduino hardware ecosystem for Kinetis L series and K series MCUs.

The Kinetis 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.

With the addition of these second-generation Kinetis K series MCUs, Freescale is taking scalability, performance, power efficiency and enablement to new levels, said Geoff Lees, SVP and GM for Freescale's MCU group. The development support we are offering with these highly integrated MCUs will redefine customers' expectations across the board.

The Kinetis software development kit (SDK) is a comprehensive software framework available initially for Kinetis K series MCUs, but planned for future availability across the entire portfolio for developing applications based on Kinetis MCUs. The SDK incorporates hardware abstraction layers, RTOS adapters, peripheral drivers, libraries, middleware, utilities and usage examples.

Freescale Processor Expert Software helps to create, configure and generate software and drivers for Freescale MCUs, and the bootloader software for Kinetis MCUs that enables in-system Flash programming over a serial connection and supports erase, program and verification capabilities.

A number of the Kinetis K series MCUs based on ARM Cortex-M4, including the Kinetis K63, K64, K24, K22, K21, K12 and K11 MCUs are in production, with Kinetis K22 derivatives and K02 MCUs sampling now, and even more devices planned for later this year. Customers can start developing with the variety of available Tower System modules and the Freescale Freedom development platform, the FRDM-K64F.
