Arm® Cortex®-M0+_超低功耗Kinetis® KL2x USB MCU

点击播放视频

Kinetis^® KL2x是超低功耗MCU系列，在Kinetis KL1x系列的基础上添加了全速USB 2.0 OTG控制器或全速免晶振USB 2.0设备控制器。

Kinetis KL2x MCU系列还与Kinetis K20 MCU (基于Arm^® Cortex®-M4内核)系列及其他Kinetis KL1x、KL2x、KL3x、KL4x系列MCU兼容，为迁移到更低功耗、更高性能和更丰富的功能集成提供了解决之道。

Kinetis L系列KL2x MCU

功能

超低功耗

新一代32位Cortex-M0+内核：与最接近的8/16位架构相比，CoreMark/mA能效得分高两倍
单周期快速I/O访问端口有利于位拆裂(bit banging)和软件协议仿真，保持了8位器件的“使用体验”
多个灵活的低功耗模式，包括新的计算时钟选项，该功能通过将外设置于异步停止模式，降低了动态功耗
LPUART、SPI, I^²C、FlexIO、ADC、DAC、LP定时器和DMA，支持低功耗模式运行，无需唤醒内核

存储器

高达512KB闪存，高达128KB SRAM
安全电路可防止对RAM和闪存内容的非法访问
32 KB ROM和内置引导加载程序，可简化MCU编程工作，支持轻松升级闪存

性能

Cortex-M0+内核，在整个工作电压和温度范围(-40ºC至+105ºC)内，可提供72MHz/96MHz的内核频率
位操作引擎，用于改善外设模块的位处理
Thumb指令集将高代码密度和32位性能结合在一起
多达8通道外设和存储器用DMA，使CPU负载更低，系统吞吐更快
时钟独立的COP可防止时钟偏移或代码失控，适用于故障安全型应用

混合信号

16位ADC，可配置分辨率、采样时间和转换速度/功率
内置温度传感器
带内置6位DAC的高速比较器
支持DMA的12位DAC
1.2 V和2.1 V参考电压(Vref)

定时和控制

两个6通道和1个2通道16位低功耗定时器PWM模块，支持DMA
两通道32位周期中断定时器为RTOS任务调度程序提供时基，或为ADC转换提供触发信号源
低功耗定时器能够在除VLLS0外的所有功耗模式下运行
带日历的实时实钟

人机接口

电容式触摸传感接口支持多达16个外部电极和DMA数据传输
通用IO带引脚中断支持、DMA请求功能及其他引脚控制选项

连接与通信

USB 2.0 OTG (全速)，带集成USB低压稳压器，可提供120 mA，3.3 V的片外电源，为5 V输入的外部组件供电；或USB 2.0设备(全速)，带时钟恢复功能，无需外部晶振
FlexIO支持通用或自定义串行外设仿真
高精度内部参考时钟，用于支持高性能通信
3个支持DMA的I2C，速率高达1 Mbps，兼容SMBus V2功能
3个支持DMA的LPUART
3个支持DMA的SPI
I^²S模块，面向音频应用
FlexIO模块支持丰富的协议，包括UART、I^²C、SPI、I^²S、PWM波形生成
智能卡接口VMSIM (ISO7816-E)
