ST STM32F446高性能 32位MCU开发方案
ST公司的STM32F446是采用高性能ARM® Cortex®-M4 32位RISC核的 32位MCU,工作频率高达180MHz,高速嵌入存储器如闪存512KB, SRAM 128KB和4KB备份SRAM.器件还集成了三个12位ADC,两个DAC,一个低功耗RTC,12个通用16位计时器以及两个32位通用计时器,工作电压1.7V-3.6V,主要用在马达驱动和应用控制,医疗设备,工业应用的PLC,逆变器,电路中断器,打印机和扫描仪,告警系统,视频互连和HVAC以及家庭音响设备.本文介绍了STM32F446xx主要特性,框图, 评估板STM32446E-EVAL主要特性,电路图,材料清单和PCB设计文件.
The STM32F446xx 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® 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 STM32F446xx devices incorporate high-speed embedded memories (Flash memory up to 512 Kbyte, up to 128 Kbyte 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.
