STM32F411微控制器属于STM32 Dynamic Efficiency™系列。这些器件为高性能F4系列的入门产品,提供了动态功耗(运行模式)和处理性能之间的最佳平衡,同时在3 x 3 mm的小封装内集成了大量的增值特性。
STM32F411 MCU可运行于工作频率100 MHz、支持浮点运算单元的Cortex®-M4内核,在运行和停机模式下实现出色的低功耗性能。
STM32F411为新型、大量数据获取模式(BAM),为数据处理进行了功耗优化,将Dynamic Efficiency提升到了一个新的水平。此BAM可通过通信外设交换大量数据,同时器件的其它部分(包括CPU)可处于省电模式。
- 性能:在100 MHz频率下,利用意法半导体的ART加速器,从Flash存储器执行时,STM32F411可实现FLASH零等待执行并达到125 DMIPS/339 CoreMark的性能。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,能够在运行模式和从Flash存储器执行时实现低至100 µA/MHz的电流消耗。停机模式下,功耗低至10 µA。
- 集成度:STM32F411器件内置高达256至512KB的Flash存储器和高达128KB的SRAM。
