The STM32G474QET6 is a high-performance MCU from STMicroelectronics featuring an ARM Cortex-M4F core at 170MHz. It provides 512KB flash and 128KB RAM. The device operates from 1.71V to 3.6V, ideal for power-sensitive applications. It includes advanced analog peripherals, multiple PWM timers, and DMA controllers. The 128-LQFP package offers extensive I/O. It is designed for digital power, motor control, and industrial applications requiring real-time performance.
- 170MHz Cortex-M4F with FPU: Handles complex control algorithms with minimal latency, enabling high-bandwidth loops.
- 128KB RAM: Large buffer for data logging or multi-axis motion profiles without external memory.
- Advanced analog peripherals (12-bit ADC, DAC, comparators): Reduces external components and improves signal chain accuracy.
- Low-voltage operation (1.71V): Extends battery life in portable and energy-harvesting designs.
Digital Power Supplies
The 170MHz Cortex-M4F with FPU executes high-frequency control loops (up to 1MHz) for LLC or PFC converters. The 128KB RAM buffers large lookup tables for nonlinear compensation.
Solar Inverters
Multiple 12-bit ADCs (up to 5Msps) sample grid voltage/current simultaneously. The PWM timers generate interleaved signals for multi-phase topologies, improving efficiency.
Industrial Drives
With 128-LQFP, it interfaces with external encoders and resolvers. The 170MHz speed handles field-oriented control with sensorless observers at high PWM frequencies.
Battery Management Systems
The 1.71V low-voltage operation allows direct connection to single-cell Li-ion. DMA transfers data from ADC to RAM without CPU intervention, reducing power consumption.
Robotics Actuators
Integrated I2S supports digital MEMS microphones for acoustic sensing. The fast PWM and dead-time insertion enable precise servo control with low torque ripple.
EV Charging Stations
Multiple communication interfaces (CAN, UART, SPI) handle protocol stacks. The brown-out detector ensures safe shutdown during grid transients.
