Product details

Active production and BOM-fit baseline

The STM32G071C8U3: The 64 MHz ARM Cortex-M0+ core, paired with 64 KB of flash and 36 KB of SRAM, provides enough headroom for a control loop with a moderate protocol stack — think a motor controller reading a resolver at 10 kHz while maintaining a CANopen fieldbus frame.

The 44 I/O lines, many multiplexed with the HDMI-CEC, I²C, SPI, UART, and IrDA peripherals, let a single part serve as both the application processor and the system supervisor — no separate CEC controller needed for a TV main board.

Analog capture and output path

Seventeen 12-bit ADC channels and two 12-bit DAC channels are integrated on-chip — enough to sample three-phase motor currents plus a DC-link voltage while outputting a reference or a bias setpoint, all without an external ADC or DAC.

Frequently asked questions

What is STM32G071C8U3's listed speed?

The core runs at 64 MHz, which is the maximum clock frequency for the ARM Cortex-M0+ in this device.

What is the pinout of STM32G071C8U3?

The pinout is documented in the STM32G071C8 datasheet — the 48-UFQFN package has 44 I/O pins plus power, ground, and the exposed thermal pad.

Can STM32G071C8U3 replace STM32G071C8?

The STM32G071C8U3 shares the same base product number and core memory configuration, but the package differs — the 'U3' suffix indicates the 48-UFQFN package versus the LQFP variant. Check the pin compatibility against your PCB footprint before substituting.
