The 12-bit ADC (13 channels) and dual 12-bit DAC cover most sensor-interface and analog-output needs, so you can keep the BOM lean for motor drives, industrial sensors, or building-automation controllers.
DMA and PWM timers offload the core for periodic tasks.
No. The STM32F091CCT7 comes in a 48-pin LQFP, while the STM32F091RCT6 is a 64-pin LQFP. They share the same core and memory but differ in pin count and I/O availability.
It uses the standard ARM Serial Wire Debug (SWD) interface, accessible on the SWDIO and SWCLK pins. The bootloader also supports UART and I²C programming.
