That core includes a single-precision FPU and a full DSP instruction set, so it handles FFTs, motor-current loops, or audio filtering without an external coprocessor. The 512 KB Flash and 132 KB RAM give enough room for a real-time OS plus a moderate application stack — think a multi-axis servo drive or a digital power supply controller. Connectivity includes CANbus, USB OTG, SPI, I²C, SAI, and SPDIF-Rx. The 114 I/O lines are in a 144-UFBGA (10x10 mm) package. ## Lifecycle: end-of-life — plan the last-time-buy now The STM32F446ZEH7 is marked end-of-life (EOL hot). Production is winding down; the window for last-time-buy orders is closing.","metaTitle":"STM32F446ZEH7 ARM Cortex-M4 MCU, 180 MHz, 512KB Flash, 144-UFBGA","metaDescription":"STM32F446ZEH7 from STMicroelectronics: 32-bit ARM Cortex-M4 at 180 MHz, 512KB Flash, 132KB RAM, 114 I/O, -40°C to 105°C, 144-UFBGA.
