Freescale MKL14Z324 Ultra-low-power, entry-level mcus Datasheet

32-bit L Series MCUs
Kinetis KL1x Family
Ultra-low-power, entry-level MCUs
Target Applications
Overview
• Low-power applications
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®
CortexTM-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.
• Battery-operated applications
• USB peripherals
• Consumer applications

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.”
Mixed Signal
Connectivity and Communications
• 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.
• I2C with DMA support, up to 400 Kb/s and
compatible with SMBus V2 features
• High-speed comparator with internal
6-bit DAC
Software and Tools
• 12-bit DAC with DMA support
• LPUART, SPI, I2C, ADC, DAC, LP timer and
DMA support low-power mode operation
without waking up the core
• 2-ch., 32-bit periodic interrupt timer provides
time base for RTOS task schedule or trigger
source for ADC conversion
Flash and SRAM
• Low-power timer allows operation in all
power modes except for VLLS0
• Freescale Tower System hardware
development environment and low-cost
demo board
Timing and Control
• One 6-ch. and two 2-ch., 16-bit low-power
timer PWM modules with DMA support
• Security circuitry to prevent unauthorized
access to RAM and flash contents
• ARM Cortex-M0+ core, 48 MHz core
frequency over full voltage and temperature
range (–40 ˚C +105 ˚C)
• Integrated development environments
• CodeWarrior for Microcontrollers V10.x
(Eclipse) IDE with Processor Expert software
modeling tool
• IAR Embedded Workbench, Keil MDK, Atollic
• Real-time clock
• Runtime software and RTOS
HMI
• MQX™ Lite, FreeRTOS, CodeSourcery
G++ (GNU)
• Capacitive touch sense interface supports up
to 16 external electrodes and DMA
data transfer
Performance
• Two SPIs with DMA support
• I2S module for audio applications
• Multiple flexible low-power modes,
including new compute mode that reduces
dynamic power by placing peripherals in an
asynchronous stop mode
• Up to 256 KB flash with 64 byte flash cache,
up to 32 KB RAM
• One LPUART and two UARTs with
DMA support
• Full ARM ecosystem support
• GPIO with pin interrupt support, DMA request
capability and other pin control options
• Bit manipulation engine for improved bit
handling of peripheral modules
