Introduction
2.1 Overview
This chapter provides an overview of the Kinetis L series of ARM® Cortex™-M0+
MCUs and KL25 product family. It also presents high-level descriptions of the modules
available on the devices covered by this document.
2.2 Kinetis L Series
The Kinetis L series is the most scalable portfolio of ultra low-power, mixed-signal ARM
Cortex-M0+ MCUs in the industry. The portfolio includes 5 MCU families that offer a
broad range of memory, peripheral and package options. Kinetis L Series families share
common peripherals and pin-counts allowing developers to migrate easily within an
MCU family or between MCU families to take advantage of more memory or feature
integration. This scalability allows developers to standardize on the Kinetis L Series for
their end product platforms, maximising hardware and software reuse and reducing time-
to-market.
Features common to all Kinetis L series families include:
• 48 MHz ARM Cortex-M0+ core
• High-speed 12/16-bit analog-to-digital converters
• 12-bit digital-to-analog converters for all series except for KLx4/KLx2 family
• High-speed analog comparators
• Low-power touch sensing with wake-up on touch from reduced power states for all
series except for KLx4 family
• Powerful timers for a broad range of applications including motor control
• Low power focused serial communication interfaces such as low power UART, SPI,
I2C etc.
• Single power supply: 1.71V - 3.6V with multiple low-power modes support single
operation temperature: -40 ~ 105 °C (exclude CSP package)
