32-bit L Series MCUs
Kinetis KL1x Family
Ultra-low-power, entry-level MCUs
Target Applications
• Low-power applications
• Battery-operated applications
• USB peripherals
• Consumer applications
Overview
The Kinetis KL1x MCU family is pin, software and tool compatible with all other
Kinetis L families, and provides additional memory, communications and analog
peripheral options beyond those offered on the KL0x family. The Kinetis KL1x MCU
family is also compatible with the Kinetis K10 family of MCUs built on the ARM
®
Cortex
TM
-M4 core, providing a migration path to higher performance and feature
integration. Devices start from 32 KB of flash in a small-footprint 5 x 5 mm 32 QFN
package, extending up to 256 KB in a 80 LQFP package. Each family member
combines ultra-low-power performance with a rich suite of analog, communication,
timing and control peripherals.

Features
Ultra Low Power
• Next-generation 32-bit ARM Cortex-M0+
core. Two times more CoreMark/mA than the
closest 8/16-bit architecture. Single-cycle fast
I/O access port facilitates bit banging and
software protocol emulation, maintaining an
8-bit “look and feel.”
• Multiple flexible low-power modes,
including new compute mode that reduces
dynamic power by placing peripherals in an
asynchronous stop mode
• LPUART, SPI, I
2
C, ADC, DAC, LP timer and
DMA support low-power mode operation
without waking up the core
Mixed Signal
• Up to 16-bit ADC with configurable resolution,
sample time and conversion speed/power.
Integrated temperature sensor. Single or
differential input mode operation for improved
noise rejection.
• High-speed comparator with internal
6-bit DAC
• 12-bit DAC with DMA support
Connectivity and Communications
• I
2
C with DMA support, up to 400 Kb/s and
compatible with SMBus V2 features
• One LPUART and two UARTs with
DMA support
• Two SPIs with DMA support
• I

S module for audio applications
Software and Tools
• Freescale Tower System hardware
development environment and low-cost
demo board
• Integrated development environments
• CodeWarrior for Microcontrollers V10.x
(Eclipse) IDE with Processor Expert software
modeling tool
• IAR Embedded Workbench, Keil MDK, Atollic
• Runtime software and RTOS
• MQX™ Lite, FreeRTOS, CodeSourcery
G++ (GNU)
• Full ARM ecosystem support
Timing and Control
• One 6-ch. and two 2-ch., 16-bit low-power
timer PWM modules with DMA support
• 2-ch., 32-bit periodic interrupt timer provides
time base for RTOS task schedule or trigger
source for ADC conversion
• Low-power timer allows operation in all
power modes except for VLLS0
• Real-time clock
Flash and SRAM
• Up to 256 KB flash with 64 byte flash cache,
up to 32 KB RAM
• Security circuitry to prevent unauthorized
access to RAM and flash contents
HMI
• Capacitive touch sense interface supports up
to 16 external electrodes and DMA
data transfer
• GPIO with pin interrupt support, DMA request
capability and other pin control options
Performance
• ARM Cortex-M0+ core, 48 MHz core
frequency over full voltage and temperature
range (–40 ˚C +105 ˚C)
• Bit manipulation engine for improved bit
handling of peripheral modules
• Thumb instruction set combines high code
density with 32-bit performance
• Up to 4-ch. DMA for peripheral and memory
servicing with reduced CPU loading and
faster system throughput
• Independent-clocked COP guards
against clock skew or code runaway
for fail-safe applications
