Kinetis L Series Arm Cortex-M0+ MCUs NXP Semiconductors Kinetis L Series Arm Cortex-M0+ Microcontrollers are an entry-level 32-bit MCU family built on the Arm Cortex-M0+ core. The Kinetis L Series 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. Manufactured using NXP's low-leakage, 90nm 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 energy efficiency and intelligence for a range of applications, including battery-operated devices, medical systems, smart meters and motor control systems.
