STM32G431CBU3 Description

The  STM32G431CBU3 is based on the high-performance Arm? Cortex?-M4 32-bit RISC core. It offers two fast 12-bit ADCs (5 Msps), four comparators, three operational amplifiers, four DAC channels (2 external and 2 internal), an internal voltage reference buffer, a low power RTC, one general-purpose 32-bit timer, two 16-bit PWM timers dedicated to motor control, seven general-purpose 16-bit timers, and one 16-bit low-power timer.
