1 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 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)
