The 17-channel 12-bit ADC and single 12-bit DAC handle analog acquisition and setpoint output directly, reducing the external converter count on the BOM.
The peripheral set includes DMA, I²S, POR, PWM, and WDT, covering most sensor-to-actuator paths without glue logic.
Both parts share the same STM32F302 base and ARM Cortex-M4 core, but the VDH6 offers 384 KB Flash and 64 KB SRAM versus the VCT6's 256 KB Flash and 40 KB SRAM, plus the 100-UFBGA package versus a 100-pin LQFP. Pin compatibility depends on the package; the BGA footprint is different from the LQFP, so a board respin is needed. Check the STM32F302 reference manual for peripheral and register compatibility.
The core runs at 72 MHz, which is the maximum rated speed for this device.
The STM32F302VDH6 is listed as RoHS compliant per STMicroelectronics standard for this product family. The 100-UFBGA package is lead-free and compatible with lead-free reflow processes.
