STEVAL-DPSG474

STEVAL-DPSG474 is a digital power supply control kit based on STM32G474RE. It consists of a main board, based on STM32G474RE MCU, an adapter board, which provides different communication interfaces and allows programming MCU through a standard 20-pin JTAG connector. The STM32G474RE MCU includes high-performance Arm® Cortex® M4 32-bit RISC core operating at up to 170MHz frequency, a FPU, a full set of DSP instructions, and high-speed embedded memories (512Kbytes of flash, 128Kbytes 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 5 fast 12-bit ADCs (5Msps), 7 ultra-fast comparators, 6 op-amp, 7 DAC channels (3 external and 4 internal), a low-power RTC, 32-bit timers, 3 timers dedicated to motor control, 7 general purpose 16-bit timers, one 16-bit low-power timer, HRTIM with 184ps resolution, specifically designed to drive power conversion systems.
