stm32f20x和stm32f10x系列兼容吗？

想要寻找一款比stm32f103vct6更强的芯片，主要是usb要支持high speed，另外pin脚尽量兼容，代码改动要小。不知道有没有这样的芯片。原来香主置顶的那个选型pdf文件现在怎么找不到了？

stm32f20x和stm32f40x系列里面有推荐的芯片？谢谢大家！

The STM32F405xx and STM32F407xx devices maintain a close compatibility with the whole STM32F10xxx family. All functional pins are pin-to-pin compatible. The STM32F405xx and STM32F407xx, however, are not drop-in replacements for the STM32F10xxx devices: the two families do not have the same power scheme, and so their power pins are different. Nonetheless, transition from the STM32F10xxx to the STM32F40x family remains simple as only a few pins are impacted

看来主要是一些电源管脚不一样。
