Description

The STEVAL-DPSG474 is a digital power supply control kit. It consists of a main

board, based on the STM32G474RE microcontroller from the STM32G4 family, and

an adapter board, which provides different communication interfaces and allows

programming the microcontroller through a standard 20-pin JTAG connector.

The STM32G474RE microcontroller includes the high-performance Arm? Cortex?

M4 32-bit RISC core operating at up to 170 MHz frequency, a floating point unit

(FPU), a full set of DSP (digital signal processing) instructions, and high-speed

embedded memories (512 Kbytes of flash memory and 128 Kbytes of SRAM).

The device embeds peripherals that allow the mathematical/arithmetic function

acceleration (CORDIC for trigonometric functions and FMAC unit for filter functions).

The MCU offers five fast 12-bit ADCs (5 Msps), seven ultra-fast comparators, six

operational amplifiers, seven DAC channels (three external and four internal), a

low-power RTC, 32-bit timers, three timers dedicated to motor control, seven generalpurpose

16-bit timers, one 16-bit low-power timer, and the high-resolution timer

(HRTIM) with 184 ps resolution, specifically designed to drive power conversion

systems.

The main board embeds a standard 64-pin DIN 41612 connector for connection

with a power board. It provides all the PWM control signals, sensing networks, and

protection features needed for a wide range of digital power supply applications.
