ST STM32F437xx和STM32F439xx系列MCU开发方案
ST公司的STM32F437xx和STM32F439xx系列是基于高性能ARM® Cortex®-M4 32位RISC内核的MCU,集成了FPU,自适应实时(ART)加速度器,工作频率高达180MHz, MPU, 225 DMIPS/1.25 DMIPS/MHz (Dhrystone 2.1)以及DSP指令,高达2MB闪存,256+4KB SRAM和32位数据总线,工作电压1.7-3.6 V,工作温度–40到+105 ℃.主要用在马达驱动和工业控制,医疗设备,PLC,逆变器,电路断路器,打印机和扫描仪,告警系统,视频连接,HVAC和家庭音响设备.本文介绍了STM32F437xx和STM32F439xx系列主要特性,框图,以及评估板STM32439I-EVAL主要特性,框图,电路图,材料清单和PCB元件布局图.
The STM32F437xx and STM32F439xx devices are based on the high-performance ARM® Cortex®-M4 32-bit RISC core operating at a frequency of up to 180 MHz. The Cortex-M4 core features a Floating point unit (FPU) single precision which supports all ARM® singleprecision 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 STM32F437xx and STM32F439xx devices incorporate high-speed embedded memories (Flash memory up to 2 Mbyte, up to 256 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.
