BUG report

1. STM32H753VIT has SDIO/SDMMC. Parametric search results SDIO and SDMMC columns both say "No."
2. Choose LQFP100 package, TFBGA100 also appears in parametric search results.

Outragеd ,

Written by feral monkeys, apparently

Cannot scroll to the end of the MCU list after filtering.. looks like they just made their crappy website display in a web view and called that an app. About what I would expect from STmicro software devs
PS. ‘Evaluation tools->Tool type’ just crashes the app. I would expect no less from ST.

Great app

This is a great app, use it all the time
One bug, when you check the box for the stm32L4 family, it just spins and spins.
