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.
Lifecycle and sourcing posture
ST lists the STM32G483CEU6 as an active product.
