我看手册写的:42xx的如下
Several prescalers are used to configure the AHB frequency, the high-speed APB (APB2)
and the low-speed APB (APB1) domains. The maximum frequency of the AHB domain is
180 MHz. The maximum allowed frequency of the high-speed APB2 domain is 90 MHz. The
maximum allowed frequency of the low-speed APB1 domain is 45 MHz
405xx和415xx如下:
Several prescalers are used to configure the AHB frequency, the high-speed APB (APB2)
and the low-speed APB (APB1) domains. The maximum frequency of the AHB domain is
168 MHz. The maximum allowed frequency of the high-speed APB2 domain is 84 MHz. The
maximum allowed frequency of the low-speed APB1 domain is 42 MHz
刚才仔细看了F411手册,似乎没问题呀

参考官网DM00115249.pdf手册 是这样写的
STM32CubeF4固件包V1.6.0
