For a 64-pin package, that analog density is generous — you can read a three-phase current-sense set, a DC-link voltage, and a few thermistors without external muxes. The DAC is useful for analog setpoint generation or sensor excitation bias. If your BOM needs more than one analog output, you will need an external DAC or a different STM32F3 variant with multiple DAC channels. ## Industrial temperature grade and CANbus for field-deployed control Includes CANbus interface. For dual-sourcing resilience, the STM32F302 family shares pin-compatibility across density options within the same package footprint, so a move to a higher-Flash sibling is a BOM-line change, not a board respin.","metaTitle":"ST STM32F302RBT7 ARM Cortex-M4 MCU, 72 MHz, 128 KB Flash","metaDescription":"STMicroelectronics STM32F302RBT7 32-bit MCU with ARM Cortex-M4 core at 72 MHz, 128 KB Flash, 32 KB RAM, 16x12-bit ADC, CANbus, -40 to 105 °C.
