STM32 L0 系列

STM32 L0系列超低功耗MCU

STM32 L0 MCU的每个部分都通过优化达到了卓越的低功耗水平。由此产生了功耗性能破纪录的真正超低功耗MCU。

ARM® Cortex®-M0+内核与STM32超低功耗特性的独有结合,使STM32 L0非常适合电池供电或供电来自能量收集的应用。

STM32 L0提供了动态电压调节、超低功耗时钟振荡器、LCD接口、比较器、DAC及硬件加密。

新的自主式外设(包括USART、I²C、触摸传感控制器)分担了ARM Cortex-M0+内核的负荷,减少了CPU唤醒次数,因此有助于减少处理时间及功耗。

它还内置有其它一些增值特性,例如16位ADC(硬件过采样)、无需外晶振的USB、超低功耗模式中的短唤醒时间及低功耗模式下仍可工作的通信外设,实现了集成特性、高性能与超低能耗之间的完美平衡。

STM32 L0具有高达64 KB闪存、8 KB RAM及高达2 KB的嵌入式EEPROM(无需闪存模拟),采用32到64针封装,包括节省空间的WLCSP36。

电流消耗参考值:

  • 动态运行模式:低至87 μA/MHz
  • 超低功耗模式 + 全RAM + 低功耗定时器:440 nA(16根唤醒线)
  • 超低功耗模式 + 备份寄存器:250 nA(3个唤醒引脚)
  • 唤醒时间:3.5 µs

Software development for STM32 made easy with STM32Cube™

Software development for STM32 made easy with STM32Cube™

STM32Cube™ is an entirely free tool, providing

STM32CubeMX , a generator of initialization C-code for STM32 MCUs, based on a graphical user interface, and one embedded software library per series of STM32 products, containing the hardware abstraction layer (HAL) for the STM32 peripherals and a set of Middleware (RTOS, USB, TCP/IP, Graphics, …) based on components that are either ST developed or open source

The initialization code and HAL and Middleware library work with all STM32 compilers, the included  project examples are set up for IAR, Keil, and the GCC based Atollic IDE. 

STM32Cube comes with hundreds of application code examples and supports the STM32 F4, STM32 F3  STM32 F2, STM32 F0 and STM32 L0 series
