|Freescale Introduces Kinetis L Series, Industry’s First Microcontrollers Built on the ARM® Cortex-M0+ Processor|
Alpha samples of entry-level Kinetis L series MCUs planned for Q2
Freescale’s early demonstration of Kinetis L series devices is possible due to the close partnership between Freescale and ARM during the Cortex-M0+ core development process. Freescale was a lead partner, providing input that helped ARM define and develop the world’s most energy-efficient processor, designed to satisfy the rigorous energy-efficiency, cost-sensitivity and ease-of-use requirements of entry-level applications such as domestic appliances, portable medical systems, smart meters, lighting, power and motor control systems.
With more than 30 years of experience in MCU development, Freescale provided valuable insights during the definition and validation of the new processor, particularly in the areas of I/O handing and debug support. This close collaboration resulted in the L series – an entry-level MCU family that combines exceptional energy-efficiency and ease-of-use with the performance, peripheral sets, enablement and scalability of the Kinetis 32-bit MCU portfolio while leveraging the inherent low-power and high-performance features of the ARM Cortex architecture.
“Our close partnership with ARM throughout the design and development of
their new core has positioned us as the first MCU supplier to produce
and demonstrate an MCU based on the Cortex-M0+ and continues our
strategy of driving to market new products based on the ARM
“Freescale was the first supplier to bring Cortex-M4 processor-based
MCUs to the mass market, and they are again taking a lead role with an
ARM processor – in this case the Cortex-M0+ processor,” said
Kinetis L series MCUs
Manufactured using Freescale’s low-leakage, 90 nm thin film storage (TFS) process technology, the Kinetis L series frees power-critical designs from 8- and 16-bit MCU limitations by combining excellent dynamic and stop currents with superior processing performance. A broad selection of on-chip flash memory densities and extensive analog, connectivity and HMI peripheral options enable increased intelligence for a range of applications.
The Kinetis L series also addresses the ease-of-use requirement critical for entry-level designs that is frequently a barrier to developers considering 32-bit solutions. Features within the MCU and in the accompanying enablement package will provide an easy look and feel, enabling quick access to new device capabilities. This will allow developers to leverage the full power of Kinetis L series MCUs, while maintaining the rapid development cycles common to entry-level designs.
Upward migration through the Kinetis portfolio is available via compatible Kinetis K series devices (built on the ARM Cortex-M4 processor) that provide access to DSP performance and advanced feature integration.
Full details of the Kinetis L series product families will be announced
ARM Cortex-M0+ processor
The ARM Cortex-M0+ processor evolves the previous-generation Cortex-M0 into a true 8-bit replacement, while maintaining compatibility with all other Cortex-M-class processors. This allows designers to reuse their existing compilers and debug tools. Enhancements to the new ARM Cortex-M0+ processor include:
As entry-level applications migrate from 8- and 16-bit to Kinetis 32-bit MCU solutions, the need for tightly integrated enablement resources is essential to fully leverage the new system resources. The Kinetis L series will benefit from a comprehensive enablement package standard for Kinetis devices, consisting of the Freescale CodeWarrior IDE, MQX RTOS and associated middleware, as well as support from the extensive ARM ecosystem.
