NXP MKL14Z64VLH4

MKL14Z64VLH4 Description

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 compatible with Kinetis K10 MCUs (based on ARM Cortex -M4) and with all other Kinetis KL1x, KL2x, KL3x, and KL4x series MCUs, providing a migration path to higher performance and feature integration.

MKL14Z64VLH4 Features

• Ultra-Low-Power

  Next-generation 32-bit ARM Cortex-M0+ core: 2x more CoreMark/mA than the closest 8/16-bit architecture

  Single-cycle fast I/O access port facilitates bit banging and software protocol emulation, keeping an 8-bit "look and feel"

  LPUART, SPI, I2C, FlexIO, ADC, DAC, LP timer, and DMA support low-power mode operation without waking up the core

  Multiple flexible low-power modes, including new, compute clocking option which reduces dynamic power by placing peripherals in an asynchronous stop mode

• Memory

  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

  16 KB ROM and built-in boot loader simplifies the effort to program MCU and allows for easy flash upgrades

• Performance

  Bit manipulation engine for improved bit handling of peripheral modules

  The Thumb instruction set combines high code density with 32-bit performance

  Independent-clocked COP guards against clock skew or code runaway for fail-safe applications

  ARM Cortex-M0+ core, 48 MHz core frequency over full voltage and temperature range (-40oC to +105oC)

  Up to 4-ch. DMA for peripheral and memory servicing with reduced CPU loading and faster system throughput

• Mixed-Signal

  Integrated temperature sensor

  12-bit DAC with DMA support

  High-speed comparator with internal 6-bit DAC

  Up to 16-bit ADC with the configurable resolution, sample time, and conversion speed/power

• Timing and Control

  Real-time clock with calendar

  A low-power timer allows operation in all power modes except for VLLS0

  Two 6-ch. and one 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

• Human-Machine Interface

  GPIO with pin interrupt support, DMA request capability, and other pin control options

  The capacitive touch sense interface supports up to 16 external electrodes and DMA data transfer

• Connectivity and Communications

  Two SPI with DMA support

  I2S module for audio applications

  One LPUART and two UART with DMA support

  FlexIO for universal or customized serial peripheral emulation

  Two I2C with DMA support, up to 1Mbps, and compatible with SMBus V2 features

  High accuracy internal clock reference to support high-performance communication  

  FlexIO module supports a wide range of protocols including UART, I2C, SPI, I2S, and PWM waveform generation
