STM32F446产品系列是高度集成的节能产品，具有高性能和丰富的连接性，Flash最小为256KB。
它利用ST的专有ART Accelerator™、智能架构、先进的Flash技术及其嵌入式ARM Cortex-M4内核，实现了225 DMIPS和608 CoreMark® 的领先性能（180MHz频率下从嵌入式Flash执行）。
通过多个接口进行高效并发通信，使工业、科技、医疗以及物联网（Internet-of-Things，IoT）应用更加智能并具有更多交互，同时先进的处理技术和动态电压调节、广泛的时钟门控以及灵活的睡眠模式实现了有效的节能。
- 性能：在180 MHz频率下，从Flash执行时，STM32F446能够提供225 DMIPS/608 CoreMark性能，并且利用意法半导体的ART加速器实现了FLASH零等待状态。 DSP指令和浮点运算单元扩大了产品的应用范围。
- 功效：该系列产品采用意法半导体90 nm工艺和ART加速器，具有动态功耗调整功能，能够在运行模式下和从Flash存储器执行时实现低至200 µA/MHz的电流消耗（@ 180 MHz）。 停机模式下，功耗为50 µA（典型值）。
- 集成：
- 2个专用音频PLL，SPDIF输入，3路半双工I²S和2路串行音频接口（SAI），支持全双工I²S和时分复用（TDM）模式。
- 多达20个通信接口（包括4个USART、2个速度达11.25 Mbit/s的UART、4个速度达45 Mbit/s的SPI、3个具有新型可选数字滤波器功能的I²C、2个CAN、SDIO、HDMI CEC以及摄像头接口）
- 两个12位DAC、三个速度为2 MSPS或7.2 MSPS（交错模式）的12位ADC定时器多达17个：频率高达180 MHz的16和32位定时器
- 使用灵活的90 MHz存储控制器可以轻松扩展存储范围，带有一个32位的并行接口，能支持Compact Flash、SRAM、PSRAM、NOR、 NAND以及SDRAM存储器
- 由于90MHz Dual quadSPI接口支持内存映射模式，可进行经济实惠的NOR闪存扩展
STM32F446系列产品在小至3.85 x 3.728 mm的封装内提供了256~512KB Flash、128KB SRAM和64~144个引脚。
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.
