Product details

170 MHz Cortex-M4 with mixed-signal peripherals

The STM32G483CET6: The 20-channel 12-bit ADC and four 12-bit DAC channels let it handle multiple sensor inputs and analog outputs without external converters, shrinking the BOM in mixed-signal designs.

Connectivity and CAN FD support

The peripheral set includes CANbus (with CAN FD support per the STM32G4 family capability), I²C, SPI, UART/USART, QSPI, SAI, and USB — covering industrial fieldbus, external memory expansion over Quad-SPI, and audio codec links. The QSPI interface at 104 MHz (family-typical) reads clean with margin for external Flash or PSRAM, useful for OTA staging or waveform look-up tables.

Surface-mount only;

Listed as Active (current product) with ROHS3 compliance.

Frequently asked questions

Does STM32G483CET6 support CAN FD?

Yes — the STM32G4 series includes CAN FD-capable controllers. The connectivity listing covers CANbus, and the family reference confirms CAN FD support. For exact register setup, the reference manual details the FD frame handling.

Does STM32G483CET6 have a built-in USB controller?

Yes — USB is listed in the connectivity set. The STM32G4 family includes USB 2.0 full-speed device and OTG support. For specific endpoint configuration, refer to the reference manual.

When sourcing STM32G483CET6, what is the closest functional second-source?

The STM32L151CBU6A is a lower-power Cortex-M3 alternative at 32 MHz with similar peripheral mix (I²C, SPI, USB, 12-bit ADC/DAC), but it lacks the 170 MHz performance, CAN FD, and QSPI of the STM32G483CET6. It is not a pin-compatible drop-in — the STM32L1 uses a different package (UFBGA) and supply voltage (1.8 V nominal). For a true second-source within the G4 family, consider another STM32G4 variant in the same package.
