Core architecture and memory headroom
The STM32F413ZHT3: The 114 I/O pins in a 144-LQFP package give plenty of room for parallel buses, sensor arrays, or a human-machine interface with an LCD controller integrated on-chip.
This MCU includes USB OTG for dual-role device/host operation, CANbus for industrial or automotive networks, QSPI for high-speed serial memory expansion, and SAI for audio serial interfaces. The data converter block provides 16 analog inputs with 12-bit resolution and two 12-bit DAC outputs, sufficient for multi-channel sensor acquisition and analog control loops.
Listed with an active lifecycle status, the STM32F413ZHT3 is a current-production part with no announced end-of-life. For dual-sourcing or a lower-power alternative, the STM32L151CBU6A (Cortex-M3, 32 MHz, 1.8 V) is a functional peer but not pin-compatible—evaluate the peripheral and memory differences before substituting.
