Analog integration — 39-channel 12-bit ADC and dual 12-bit DAC
The on-chip data converters include a 39-channel 12-bit ADC and two 12-bit DACs. That many ADC channels cover three-phase current sensing plus DC-link voltage and temperature feedback without an external multiplexer. The dual DAC can generate offset references or analog setpoints for an external power stage. For designs that need more than 12-bit resolution, an external ADC is still required, but the integrated converters reduce BOM count for the majority of industrial-control and instrumentation tasks.
Connectivity — CAN, USB, and five serial interfaces
The STM32F303VDH6 supports CANbus, USB, I²C, SPI, UART/USART, IrDA, and LINbus. CAN and USB are on the same die, so a single MCU can serve as a CAN-to-USB gateway or a fieldbus node with a debug/programming port. The 84 GPIOs leave room for parallel LCD or memory interfaces alongside the serial channels. The internal oscillator eliminates the external crystal for many applications, though a crystal is still recommended for CAN or USB timing accuracy.
Package and temperature grade — 100-UFBGA, -40 to 85 °C
Housed in a 100-ball UFBGA measuring 7x7 mm, the STM32F303VDH6 is sized for compact PCBs. The BGA footprint requires controlled solder-paste deposition and X-ray inspection.
Lifecycle and sourcing — confirm status before BOM commitment
The lifecycle record shows the STM32F303VDH6 as active per ST's product status, but an EOL-hot flag appears in the sourcing data. This contradiction means the part may be approaching end-of-life or subject to a last-time-buy window. Before freezing this MCU into a production BOM, verify the current lifecycle stage directly with ST or through your distributor.
