180 MHz Cortex-M4 with 512 KB Flash in a 144-ball UFBGA
The STM32F446ZEJ6 is an ARM Cortex-M4 32-bit single-core MCU from the STM32F4 series, clocked at 180 MHz and packing 512 KB of Flash (512K x 8) and 128 KB of SRAM (128K x 8).
Peripheral set for mixed-signal and connectivity-heavy designs
The 114 general-purpose I/O lines, combined with the PWM timer channels and the DMA controller, let the MCU handle motor-drive commutation and data streaming without CPU intervention — a common pattern in industrial servo and robotics control boards.
