It's a STM32F072. The requirements were 2 SPI ports (one for the FPGA and one for the SD card), battery backed RTC, USB, and a TQFP48 package.
I recently discovered the STM32L433 which is even more powerful and pin-compatible. I still have to check how fast the SD card access is,
but the F072 should be fast enough.

Great choice, the stm32f07x series is a great mcu for USB. I recently upgraded to some of my designs to the same chip family and have been enjoying getting to know the chip.
