Migrating from L431CCU6 to F412CEU6

Hello,

I'm planning to migrate from L431CCU6 to F412CEU6 MCU and as per CubeMX, all the pins and power scheme matches. But I see there is Vcap on pin 22 of F412 MCU. Is it okay to skip it with below setup? Adding this cap will need redesign and we want to utilize the same boards designed for L431. Thank you!

Absolutely not, capacitor of proper value as per datasheet, connected to Vcap, is vitally needed for the 'F412 to work.
