stm32l + fatfs

All of the FATFs examples (and indeed, CubeMX) appear to be geared toward the STM32F series chips when using FatFS. I want to use the STM32L433, insofar as I have a lot of my application already written for that device. Now they want to add a file system and SD card...


Am I "spitting into the wind" trying to get a L series chip to work with this? Does it not have enough horsepower to do the job? I'll be writing something on the order of 35 bytes at a 720 samples/second rate. Will this keep up with DMA?

Writing to another device is possible, but the ultra-lower power consumption is one of the attractions to this chip.
