It sits in the STM32G4 series, which targets digital power conversion, motor control, and industrial sensing — applications where the combination of a fast math-capable core and dense analog peripherals reduces external component count.
Analog peripheral density — 23 ADC channels, 4 DAC outputs
This part carries 23 external analog-to-digital converter channels at 12-bit resolution and four 12-bit digital-to-analog converters. For a three-phase motor drive with current sensing on each phase plus DC-link voltage and temperature feedback, the ADC channel count covers the bill without an external mux. The four DAC outputs can generate analog reference voltages or feed a set-point directly to an external amplifier — useful in programmable power supplies or waveform generation.
Connectivity and control peripherals
Five 16-bit timers with PWM generation and a dedicated PWM timer are standard for the series. The built-in brown-out detect and power-on reset simplify the power-supply supervisory circuit.
Housed in a 64-ball UFBGA package measuring 5x5 mm (supplier device package 64-UFBGA), this is a fine-pitch BGA intended for space-constrained PCBs.
