1. Kinetis L family introduction
Kinetis L series microcontrollers (MCUs) combine the
exceptional low-power performance with energy
efficiency and ease of use of the new ARM
®
Cortex
®
-
M0+ processor with the performance, peripheral sets,
enablement, and scalability of the Kinetis 32-bit MCU
portfolio.
The Kinetis ultra-low-power 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.
Kinetis ultra-low-power L series MCUs are also
hardware- and software-compatible with the ARM
Cortex-M4-based Kinetis K series, providing a scalable
migration path for higher performance, memory, and
feature integration.

Kinetis KL1x family key features
2. Kinetis KL1x subfamily overview
The Kinetis KL1x is a general-purpose ultra-low-power MCU family, providing additional memory,
communications, and analog peripheral options, beyond those offered in the Kinetis KL0x MCU family.
The KL1x MCU family is also compatible with the Kinetis K10 MCU family (based on the ARM
Cortex-M4 core) and with all other Kinetis KL2x, KL3x, and KL4x series MCU families, providing a
migration path for higher performance and feature integration.
•
KL13 – Provides up to 64KB flash and 8KB SRAM, built-in ROM boot-loader, enhanced mixed
signal integration with high-accuracy VREF, ISO7816, two LPUARTs, FlexIO, and high-accuracy
48 MHz IRC
KL14 – Broad offering with mixed signal integration, connectivity, and ultra-low power
KL15 – Expansion from the KL14 family with the addition of 16-bit ADC and TSI
KL16 – Expansion from the KL15 with up to 256 KB Flash and 32 KB SRAM, with the addition
of I2S and 16-bit SPI
KL17 – Latest member of KL1x, with up to 1:4 SRAM-to-Flash ratio, built-in ROM boot-loader,
enhanced mixed signal integration with high-accuracy VREF, ISO7816, two LPUARTs, FlexIO,
and high-accuracy 48 MHz IRC

3. Kinetis KL1x family key features
•
•
Ultra-low-power 48 MHz devices supported with base line functions, up to 256 KB of Flash, and
32 KB of RAM.
The asynchronous DMA allows for energy-saving peripherals; for example, ADC, UART, and
Timer / PWM, to trigger asynchronous DMA request in the STOP / VLPS modes to perform DMA
transfer and return to current power mode with no CPU intervention.
The LPUART supports asynchronous transmit and receive operations to the bus clock, supporting
communication down to the STOP / VLPS modes. Configurable receiver baud rate oversampling
ratio from 4× to 32× allowing for higher baud rates with lower clock sources.
,
The SPI supports slave mode address match wakeup function and first message capture down to
the STOP / VLPS modes.
The I
2
C supports multiple address match wakeup function down to the STOP / VLPS modes.
The FlexIO is capable of emulating multiple serial interfaces, for example, UART, SPI, I
2
C, IrDA,
and is fully-functional under the STOP / VLPS modes.
The LPTPM supports 16-bit timer input capture, output compare, and PWM functions, down to the
STOP / VLPS modes.
The LPTMR supports 16-bit timer and pulse counter functions in all power modes.
The RTC supports 32-bit second counter with second interrupt and programmable alarm in all
power modes with included temperature and voltage compensation.

The ADC supports single conversions in multiple result registers down to the STOP / VLPS modes
with hardware averaging and automatic compare modes.
The CMP supports threshold crossing detection in all power modes (except VLLS0) along with a
triggered compare mode for lower average power compares.
The DAC and VREF support static reference in all power modes (except VLLS0).
The TSI supports wake-on capacitive touch on single channel in all power modes.
The LLWU supports eight wakeup pins, RESET and NMI wakeup pins, and energy-saving
peripherals in the LLS and VLLSx modes.
Outstanding low-power operation with core mark currents down to 100 µA / MHz, state retention
stop mode down to 1.7 µA, with 7.5 µS wakeup time, and lowest power mode down to 87 nA.
Highly reliable, fast-access Flash memory with four levels of protection for code security /
protection.
Faster time to market with comprehensive enablement solutions, including SDK (drivers, libraries,
stacks), IDE, boot-loader, RTOS, online community, and more.
