The 512 KB Flash and 128 KB RAM are sized for a mid-complexity application. ## Connectivity and peripherals — what is on the bus This MCU carries CANbus, USB OTG (host/device), SPDIF-Rx, SAI (serial audio interface), and a flexible memory controller (EBI/EMI) that can map external SRAM, NOR Flash, or a parallel LCD. The CANbus interface is a single node — enough for an industrial gateway or automotive body controller, but not a multi-CAN backbone. The 81 GPIOs in the 100-LQFP package give you room for a parallel display, external memory, and a handful of sensors without multiplexing. The 16-channel 12-bit ADC and dual 12-bit DAC cover analog front-end needs for current sensing or audio output.","metaTitle":"ST STM32F446VET7 ARM Cortex-M4 MCU, 180MHz, 512KB Flash","metaDescription":"STMicroelectronics STM32F446VET7 32-bit MCU: ARM Cortex-M4 at 180MHz, 512KB Flash, 128KB RAM, -40 to 105°C, 100-LQFP.
