STM32F4相对于STM32F1的改进不只一点点,为了便于初学者了解,我们比对相关资料将改进点进行了汇总。
STM32F1和STM32F4区别 (安富莱整理)
◆ F1采用Crotex M3内核,F4采用Crotex M4内核。
◆ F1最高主频 72MHz, F4最高主频168MHz。
◆ F4具有单精度浮点运算单元,F1没有浮点运算单元。
◆ F4的具备增强的DSP指令集。F4的执行16位DSP的时间只有F1的30%~70%。F4执行32位DSP指令 的时间只有F1的25%~60%。
◆ F1内部SRAM最大64K字节, F4内部SRAM有192K字节(112K+64K+16K)。
◆ F4有备份域SRAM(通过Vbat供电保持数据),F1没有备份域SRAM。
◆ F4从内部SRAM和外部FSMC存储器执行程序的速度比F1快很多。F1的指令总线I-Bus只接到Flash上,从SRAM和FSMC取指令只能通过S-Bus,速度较慢。F4的I-Bus不但连接到Flash上,而且还连接到SRAM和FSMC上,从而加快从SRAM或FSMC取指令的速度。
◆ F1最大封装为144脚,可提供112个GPIO;F4最大封装有176脚,可提供140个GPIO。
◆ F1的GPIO的内部上下拉电阻配置仅仅针对输入模式有用,输出时无效。而F4的GPIO在设置为输出模式时,上下拉电阻的配置依然有效。即F4可以配置为开漏输出,内部上拉电阻使能,而F1不行。
◆ F4的GPIO最高翻转速度为84MHz,F1最大翻转速度只有18MHz。
◆ F1最多可提供5个UART串口,F4最多可以提供6个UART串口。
◆ F1可提供2个I2C接口,F4可以提供3个I2C接口。
◆ F1只有12个DMA通道,F4有16个DMA通道。F4的每个DMA通道有4*32位FIFO,F1没有FIFO。
◆ F1的SPI时钟最高速度为 18MHz, F4可以到37.5MHz。
◆ F1没有独立的32位定时器(32位需要级联实现),F4的TIM2和TIM5具有32位上下计数功能。
◆ F1和F4都有2个I2S接口,但是F1的I2S只支持半双工(同一时刻要么放音,要录音),而F4的I2S支持全双工,放音和录音可以同时进行。
