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.","metaTitle":"STM32F412ZET6 STM32F4 ARM Cortex-M4 MCU, 100MHz, 512KB Flash","metaDescription":"STM32F412ZET6 32-bit ARM Cortex-M4 MCU at 100MHz, 512KB Flash, 256KB RAM, 114 I/O, 144-LQFP, -40 to 85°C.
