The STMicroelectronics digital power supply control kit 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, a full set of DSP instructions, and high speed embedded memories. This device embeds peripherals that allow the mathematical or arithmetic function acceleration.
