The 11-channel 12-bit ADC and single 12-bit DAC handle mixed-signal tasks.
The 32-UFQFPN package with exposed pad (5×5 mm) provides 24 I/Os. Surface-mount assembly follows standard reflow profiles for UFQFPN.
The STM32F301K8U7 and STM32F301K8U6 are pin-compatible and share the same 32-UFQFPN package, 72 MHz core, and 64 KB Flash.
