The 384 KB Flash and 80 KB RAM leave room for a moderate firmware image and a few KB of data logging or communication buffers. The 86 available I/O in a 100-LQFP package give you enough pins to wire up parallel displays, multiple encoder interfaces, or a bank of relay drivers without resorting to port expanders. The 14x14 mm footprint is manageable for four-layer boards; keep the analog and digital grounds split if you're using all 39 ADC channels. ## Analog integration — 39-channel ADC and dual DAC The 39-channel 12-bit ADC array covers multi-sensor acquisition. The two 12-bit DACs can generate analog setpoints or bias voltages. It does not carry AEC-Q100 qualification. ## Connectivity — CAN, USB, and serial fieldbuses On-chip CANbus (2.0B) interfaces directly with industrial fieldbus nodes; USB full-speed handles data logging or HID-class peripherals. The I2C, SPI, and UART/USART blocks cover sensor bridges, serial displays, and Modbus RTU slaves. IrDA and LINbus are available for legacy automotive or infrared communication links. The peripheral set is fixed — no internal PHY for Ethernet or CAN FD.","metaTitle":"ST STM32F303VDT6 ARM Cortex-M4 MCU, 72 MHz, 384 KB Flash, 100-LQFP","metaDescription":"STMicroelectronics STM32F303VDT6 32-bit MCU with ARM Cortex-M4 core at 72 MHz, 384 KB Flash, 80 KB RAM, 86 I/O, 39x12b ADC, 2x12b DAC, CAN/USB.
