STM32L4 series of ultra-low-power and performance MCUs
STM32L432/442 & STM32L452/462 devices extend the ultra-low-power portfolio and performance with an ARM® Cortex®-M4 core with DSP and floating-point unit (FPU) at 80 MHz.
- The STM32L432 portfolio offers from 128 to 256 Kbytes of Flash in very small plastic package QFN-32 (5 x 5 mm).
- The STM32L452 portfolio offers from 256 to 512 Kbytes of Flash and from 48-to 100-pin packages.
精选 视频
B-U585I-IOT02A探索套件为STM32U585AI微控制器提供了一个完整的演示和开发平台, 配备Arm® Cortex®-M33内核、Arm® TrustZone®、Armv8-M主线安全扩展、2 Mb Flash存储、786 Kb SRAM存储，以及智能外设资源。
本视频涉及STM32L5，这是我们最近推出的超低功耗微控制器，它带来了新的安全维度。STM32L5已安全投产，其整个生态系统已可用，包括硬件套件、软件工具、固件，以及所有文档。这是我们首款基于Cortex-M33及其Trustzone并使用特定意法半导体安全实现的STM32，观看视频以查找更多信息！
STM32L5基于与意法半导体安全实现相结合的Arm® Cortex-M33和TrustZone®技术。在您的STM32L562E-DK探索板上已禁用TrustZone（出厂设置），您可以像在其他STM32器件上那样进行开发。本视频演示了如何使用STM32CubeProgrammer在STM32L562E-DK探索板上启用TrustZone，并使用STM32CubeIDE创建、编译、调试或运行新项目。此外还演示了如何打开STM32CubeL5 MCU软件包中提供的示例项目，修改、编译、调试或运行该项目。有关更多信息，您可以参阅AN5394和AN5424应用笔记。
