Cortex-M0 core at 48 MHz — throughput for sensor fusion and control loops
The STM32F048G6U6: The ARM Cortex-M0 core runs at 48 MHz, which sets the instruction throughput ceiling for real-time tasks like reading a 12-bit ADC channel and updating a PWM duty cycle within a single control period. With 32 KB of flash and 6 KB of SRAM, the memory budget fits a modest application stack — a sensor hub logging data over I2C and USB, for example, leaves room for the HAL and a small RTOS.
28-UFQFPN 4x4 mm — board-fit for space-constrained layouts
Surface-mount assembly on a standard FR-4 board is straightforward; the exposed pad under the package aids thermal dissipation if the MCU drives multiple I/O pins continuously.
