STM32F413/423微控制器为高性能STM32F4系列的入门产品,实现了运行模式下的动态功耗和处理器性能之间的最佳平衡,即使在3.951 x 4.039 mm的小封装内也集成了大量的增值特性。

STM32F412/423 MCU提供了工作频率为100 MHz的Cortex®-M4内核(具有浮点单元)的性能,同时还能在运行和停机模式下实现出色的低功耗性能。由于STM32F413/423配备2个RAM,且其中一个(64-KB SRAM2)通过I/D总线连接,因此该性能更为高效。

STM32F413/423利用大量数据获取模式(BAM)将批量数据处理进行功耗优化,将动态功耗效率提升到了一个新的水平。BAM允许通信外设实现批量数据交换,同时器件的其它部分(包括CPU)可保持在省电模式。

  • 性能:在100 MHz频率下,从Flash存储器执行时,STM32F401能够提供125 DMIPS/339 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:ST该系列产品采用意法半导体90 nm工艺,使用ART加速器和动态功耗调整功能,从Flash存储器执行指令,运行模式下可实现低至112 µA/MHz的电流消耗。停机模式下,功耗低至18 µA。
  • 集成度:STM32F413/F423器件内置高达1024至1536 KB的Flash存储器和高达320 KB的SRAM。 
    具备从48到144引脚各类封装。
    • 10路USART,速率高达12.5 Mbit/s
    • 5路SPI(I²S多路传输),速度高达50 Mbit/s

    • 真随机数发生器

STM32F4 Access lines: Entry level and still an F4!

The STM32F4 Access lines are made of STM32F401, STM32F410,STM32F411, STM32F412 and STM32F413/423 devices. They are the entry-level STM32F4 microcontrollers for cost-conscious applications requiring performance, energy efficiency, integration and connectivity.

Access lines, but still with performance and power efficiency:

  • Performance up to 100 MHz/ 125 DMIPS with dynamic efficiency down to 89 µA/MHz in Run mode
  • ST's Adaptive Real Time (ART) accelerator allowing zero-wait execution from embedded Flash memory
  • Batch Acquisition Mode (BAM) for Always-on data collection, even when the core is stopped, and dynamic power scaling
  • Low-power digital microphone interface for acquisition of up to 6 microphones

Access lines, but still with high integration and compactness:

  • Wide memory choice from 128 Kbytes of Flash memory / 32 Kbytes of RAM up to 1.5 Mbyte of Flash memory / 320 Kbytes of RAM
  • Smallest Cortex-M4 based device available in the entire STM32 portfolio, down to 2.553 x 2.579 mm

Access lines, but still with rich connectivity:

  • Up to 10 UARTs, USB OTG FS, 3xCANs, and up to 5 SPI/I2S interfaces
  • LCD parallel interface, 8080/6800 modes
  • Quad-SPI and FMC parallel interfaces supporting a large choice of external memory types

Note : To ease your upgrade from STM32F1 designs to STM32F4 access lines, refer to our application note AN4904.

Access lines, but still with a comprehensive development environment including:

  • STM32F412 Discovery kit (32F412GDISCOVERY) combines STM32F412 features with color touchscreen, joystick, stereo MEMS microphones, external memory capabilities, full-speed OTG USB interface and more.
  • STM32 Nucleo-144 development board (NUCLEO-F412ZG) with an STM32F412 MCU as well as Arduino, ST Zio and morpho connectivity provides an affordable and flexible way to try out new concepts and build prototypes.
