Greetings to all the GEEKS.

Well i am looking for STM32 microcontroller that has usb host capability as well as it can interface with micro sd card or sd card. The reason for usb host capability is --- I want to store the data on to usb pen drive that is fat or fat32 formatted. I want the interface with micro sd card or sd card for the same reason. If usb pen drive is not attached then i want to store data on to micro sd card or sd card.

Any advice will be helpful. I don't mind the usb host speed i.e. i am okay if i don't get usb host capability on full speed.

The USB OTG can work as host. It is present on STM32F105/F107/F2xx/F4xx/F7xx/L4x5/L4x6 series.

All of them have a an SPI than can be used for the SDCARD (in SPI mode)

You will get better performances by using

STM32F2xx/F4xx/F7xx because they embed a SDIO peripheral ideal for the SDCARD.
