製品概要
概要
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 general-purpose 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.
An external 5 V supply voltage can supply the board either through a dedicated connector or through the main connector. The adapter board features a configurable user communication (SMBus, CAN, or RS-232) with two DB9 connectors and the appropriate transceiver ICs, a standard STDC14 14-pin connector, which provides the SWD interface for debugging and USART communication for user interface (UI), and the standard JTAG connector for programming.
The board also includes a reset button and a termination resistance between the CAN lines.
You can easily connect the STEVAL-DPSG474 to another control board via opto-coupled serial communication and dedicated connectors.
