The peripheral set includes CANbus, USB OTG, QSPI, multiple SPI/I²C/UART, and an LCD interface — enough connectivity for an HMI panel or industrial gateway without external bridge chips.
Flash wait-state budget at 100 MHz
At 100 MHz the Cortex-M4 core needs at least one flash wait state inserted before raising the clock above roughly 30 MHz. Bump the wait-state register to 1 in the system init routine or the first branch out of reset hard-faults. The 512 KB Flash is organised as 4 KB and 64 KB sectors — size the OTA staging area accordingly.
Brown-out detect and POR are integrated, so an external supervisor is optional unless you need a precise reset threshold.
144-LQFP footprint and layout notes
Decouple each VDD pair with a 100 nF ceramic close to the pin; a 4.7 µF bulk cap per supply region handles transient draw.
ST lists the STM32F412ZET6 as Active.
