170 MHz Cortex-M4 with FPU — real-time control headroom
That core speed puts it in the class for digital power control, motor-field-oriented control loops, and mixed-signal acquisition where the math pipeline needs to close a current loop inside a few microseconds.
Peripheral set and connectivity for mixed-signal control
On the analog side, the part integrates 21-channel 12-bit ADC and four 12-bit DAC channels — enough for simultaneous three-phase current sensing plus a voltage or temperature feedback. Digital interfaces include CANbus, I²C, SPI, QSPI, UART/USART, USB, SAI, and IrDA, so it can talk to an inverter gate driver, an isolated CAN transceiver, and a serial Flash on the same die without an external bridge. The brown-out detect, POR, and watchdog peripherals are standard for unsupervised industrial operation.
The 48-UFQFN with exposed pad (7x7 mm body) is a compact surface-mount package; the thermal pad needs a via-stitched ground plane on the PCB to pull heat from the die when the core and peripherals run near full load.
ST lists the STM32G483CEU6 as an active product.
