STMicroelectronics’ STM32G484 microcontroller is suitable for next-generation digital power converters and mixed-signal control systems, combining high processing performance with precise analog control. It features a 170MHz Arm Cortex-M4 core with extensions, augmented by dedicated hardware math accelerators that offload complex control algorithms. This architecture enables fast control loops and real-time signal processing for high-efficiency power conversion and other demanding control applications.
To interface directly with power electronics, STM32G484 integrates rich analog and timing peripherals. It offers five multi-channel, simultaneous voltage and current sensing, along with six on-chip programmable-gain operational amplifiers and seven comparators for real-time signal conditioning and protection.
The STM32G484 features extensive connectivity for system integration. Also, multiple low-power modes, such as sleep, stop, standby, and shutdown help to minimize energy consumption when full performance is not required. Developers also benefit from the STM32 ecosystem: the STM32CubeG4 software package provides HAL/LL libraries and control examples, and tools like STM32CubeMX and STM32CubeIDE are supported. This ecosystem, combined with the chip’s dual-bank Flash enables rapid development of safe, high-performance digital power solutions.
Part Number: B-G474E-DPOW1
The B-G474E-DPOW1 Discovery Kit is a complete digital power development platform built around an STM32G4 MCU. It features an onboard buck-boost converter (with selectable internal or external input and resistive load bank) and a high-brightness RGB LED, allowing developers to evaluate DC-DC conversion and LED lighting control designs. A Class-D audio amplifier circuit is also included to demonstrate digital power in audio applications. The kit provides rich user interface and connectivity, including four user LEDs, a 4-direction joystick, a USB Type-C™ port supporting USB Power Delivery 3.0, a Micro-USB port (for ST-Link), and extension headers for additional peripherals.
