Product details

Peripherals and connectivity for real-time control

The STM32G031K6T6: The connectivity set covers I²C, IrDA, LINbus, SPI, SmartCard, and UART/USART — enough for motor-drive feedback, serial sensor links, and human-machine interfaces. An 18-channel 12-bit SAR ADC handles analog inputs, and the oscillator options (external or internal) simplify clock-tree design.

Cross-ship with STM32G0 series siblings

Within the STM32G0 family, the STM32G031K6T6 is pin-compatible with higher-density variants. The 32-LQFP footprint, supply range, and peripheral set are identical — only the Flash size changes.

Frequently asked questions

Where can I buy STM32G031K6T6?

Submit a request for current pricing and availability; we confirm both at quote time.

What is the difference between STM32G031K6T6 and STM32G031K8T6?

The only difference is Flash memory size: the K6 variant has 32 KB, while the K8 variant has 64 KB. Both share the same 32-LQFP package, 64 MHz core, 8 KB RAM, and peripheral set, making them pin-compatible and software-compatible for a firmware-size upgrade.

What are the equivalent parts for STM32G031K6T6?

Within the STM32G0 series, the STM32G031K8T6 (64 KB Flash) and STM32G031K4T6 (16 KB Flash) are pin-compatible density variants. Outside the series, the STM32L151CBU6A is a different architecture (Cortex-M3, 32 MHz) and is not a direct second-source substitute.
