- 10个外部状态输入（电流限制、零电压/零电流检测等）和6个故障输入
高分辨率定时器的主要特性如下：
- 184 ps 分辨率（适用于所有操作模式）
- 可变占空比、可变频率和临界模式
- 许多可降低CPU负荷的特性
- 谷值跳过模式和斜坡补偿
- 每个定时器都有一路DMA通道
- 内置的突发模式控制器和特定拓扑的模式：推挽和谐振。
- 定时器之间的大量互连用于：
- 复位/启动相邻定时器
- 设定 / 复位 / 切换其他输出
- 易于编程实现的简单高分辨率执行流程（等同于4.6 GHz的定时器）
精选 视频
As part of our embedded online event, we had the pleasure of filming with Reinhard Keil, a Senior Director of Embedded Tools at ARM.
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!
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.
