文介绍了 STM32F405xx 和 STM32F407xx 主要特性,方框图,MCBSTM32F400 评估板主要特性,技

术指标,方框图以及电路图和 PCB 元件布局图.STM32F405xx/STM32F407xx:ARM Cortex-M4 32b

MCU+FPU, 210DMIPS, up to 1MB Flash/192+4KB RAM, USB OTG HS/FS, Ethernet, 17 TIMs,

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 totwo APB buses, two

AHB buses and a 32-bit multi-AHB bus matrix.All devices offer three 12-bit ADCs, two

DACs, a low-power RTC, twelve general-purpose 16-bit timers including two PWM timers

for motor control, two general-purpose 32-bit timers. a true random number generator

(RNG). They also feature standard and advanced communication interfaces.● Up to

three I2Cs● Three SPIs, twoI2Ss full duplex. To achieve audio class accuracy, the

I2S peripherals can be clocked via a dedicated internal audio PLL or via an external

in the –40 to +105 °C temperature range from a 1.8 to 3.6 V power supply.

The supply voltage can drop to 1.7 V when the device operates in the 0 to 70 °C

temperature range and PDR is disabled. A comprehensive set of power-saving mode allows

the design of low-powerapplications.The STM32F405xx and STM32F407xx family offers

devices in four packages ranging from 64 pins to 176 pins. The set of included

peripherals changes with the device chosen.These features make the STM32F405xx and

STM32F407xx microcontroller family suitable for a wide range of

applications:STM32F405xx 和 STM32F407xx 主要应用:● Motor drive and application

control● Medical equipment● Industrial applications: PLC, inverters, circuit

breakers● Printers, and scanners● Alarm systems, video intercom, and HVAC● Home
