STM32L0 - ARM Cortex-M0+ ultra-low-power MCUs

STM32L0系列超低功耗MCU

STM32L0系列是意法半导体的入门级32位超低功耗MCU产品组合，旨在实现卓越的低功耗水平。由此产生了真正的超低功耗MCU，125℃时的功耗为世界最低。

ARM^® Cortex^®-M0+内核与STM32超低功耗特性的独有结合，使STM32L0非常适合电池供电或供电来自能量收集的应用。

为了实现最佳功率效率，STM32L0提供动态电压调整、超低功耗时钟振荡器和短唤醒时间。新的自主式外设（包括USART、I²C和触摸传感控制器）降低了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率消耗。

为了降低总应用BOM成本，STM32L0集成了低功耗比较器、嵌入式EEPROM和无晶体USB接口。

它还内置其它一些增值特性，例如16位ADC（硬件过采样）、双通道DAC、硬件加密、能够在超低功耗模式下运行的通信外设，实现了集成特性、高性能与超低功耗之间的完美平衡。

STM32L0 MCU具有高达192 KB的闪存、20 KB RAM、及高达6 KB的嵌入式真正EEPROM（无需仿真），采用14到100引脚封装（包括空间节约型WLCSP36封装）。

STM32L0 MCU在比较超低功耗微控制器效率的标准化EEMBC™ ULPBench^®测试中获得244分。

电流消耗参考值：

动态运行模式：低至49 µA/MHz（采用外部DC/DC）和76 µA/MHz（采用LDO）
超低功耗模式 + 全RAM + 低功耗定时器：340 nA（16根唤醒线）
超低功耗模式 + 备份寄存器：230 nA（2个唤醒引脚）
唤醒时间：3.5 µs

STM32L5 Series ultra-low power microcontroller with more security

This video is about the STM32L5, our recently announced ultra-low power microcontroller bringing a new security dimension. The STM32L5 is now in full production and all its ecosystem is available including hardware kits, software tools, firmware and all documentations of course. This is our first STM32 based on Cortex-M33 and its Trustzone and using specific ST security implementation - watch the video to find out more!

How to enable TrustZone<sup>®</sup> and start a project with STM32L5

How to enable TrustZone^® and start a project with STM32L5

The STM32L5 is based on Arm® Cortex-M33 and TrustZone® technology combined with STMicroelectronics security implementation. On your STM32L562E-DK discovery board, TrustZone is disabled (factory setting) and you can develop as on any other STM32 device. This video shows how to enable TrustZone on STM32L562E-DK discovery using STM32CubeProgrammer and create, compile and debug or run a new project with STM32CubeIDE. It also shows how to open an example project delivered in STM32CubeL5 MCU Package, modify, compile and debug or run it. For further information, you can refer to AN5394 and AN5424 application notes.
