ST STM32F407IG ARM Cortex M4 32位MCU开发方案
ST公司的STM32 F4系列是高性能的基于ARM Cortex M4的32位微控制器,工作频率高达168MHz. Cortex M4具有浮点单元(FPU)但精度,支持所有的ARM单精度数据处理指令和数据类型,具有DSP指令和自适应的实时加速器(ART),允许从闪存中零等待状态实现,存储器保护单元和210 DMIPS/1.25 DMIPS/MHz (Dhrystone 2.1).主要用在马达驱动和应用控制,医疗设备,工业应用如PLC,逆变器,电路断路器,打印机和扫描仪,告警系统,HVAC和家庭音频设备.本文介绍了STM32F407xx系列主要特性,方框图以及STM3240G-EVAL评估板主要特性, 评估板硬件布局和配置图, 元件布局图和详细电路图.
The STM32F405xx and STM32F407xx family is based on the high-performance ARM® Cortex™-M4 32-bit RISC core operating at a frequency of up to 168 MHz. The Cortex-M4 core features a Floating point unit (FPU) single precision which supports all ARM single precision data-processing instructions and data types. It also implements a full set of DSP instructions and a memory protection unit (MPU) which enhances application security.
The Cortex-M4 core with FPU will be referred to as Cortex-M4F throughout this document.
The STM32F405xx and STM32F407xx family incorporates high-speed embedded memories (Flash memory up to 1 Mbyte, up to 192 Kbytes of SRAM), up to 4 Kbytes of backup SRAM, and an extensive range of enhanced I/Os and peripherals connected to two APB buses, two AHB buses and a 32-bit multi-AHB bus matrix.
