ST STM32F407xx系列32位MCU开发方案

ST公司的STM32F407xx系列产品是基于ARM®Cortex™-M4内核的32位RISC MCU,工作频率高达168MHz. Cortex-M4内核具有单精度浮点单元(FPU),支持所有的ARM单精度数据处理指令和数据类型,还能实现所有的DSP指令集和存储器保护单元(MPU),增强了应用保密性,主要用在马达驱动和应用控制,医疗设备,工业设备如PLC,逆变器,电路中断器,打印机和扫描仪以及消费类电子如HVAC,家庭音响设备等.本文介绍了STM32F407xx系列主要特性,框图,以及STM3240G-EVAL评估板主要特性,框图,电路图,材料清单和PCB元件布局图.

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 (M PU) which enhances application security. The Cortex-M4 core with FPU will be referred to as Cortex-M4F through out 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, three AHB bu ses and a 32-bit mu lti-AHB bus matrix.
