Product details

The 30 I/Os in a 32-LQFP package (7x7 mm body) keep the board area small while leaving room for a dozen analog inputs and a couple of DAC outputs.

Analog and connectivity peripherals

A 13-channel 12-bit ADC and two 12-bit DAC channels handle sensor conditioning and closed-loop analog outputs. The standout is the integrated USB Type-C interface with Power Delivery support — this saves an external PD PHY and controller, a real BOM win for USB-C sink or source designs.

Package and rework — 32-LQFP with visible leads

The 32-LQFP package has a 7x7 mm body and 0.8 mm pitch. The leads are fully visible and accessible, so rework with a hot-air station is straightforward — no hidden pads, no underfill.

The base product number is STM32G081, which covers the full family of density and package variants.

Frequently asked questions

What is the maximum clock speed of STM32G081KBT6?

The core runs at 64 MHz. At that speed the Flash needs one wait state inserted (per the STM32G0 reference manual), which the hardware handles automatically when the clock is configured above 24 MHz.

Is STM32G081KBT6 RoHS compliant?

Yes, it is ROHS3 compliant, meaning no exemptions for lead, mercury, or other restricted substances under the EU RoHS directive.

What is the difference between STM32G081KBT6 and STM32G071KBT6?

The STM32G081KBT6 adds USB Type-C Power Delivery support that the STM32G071KBT6 lacks. Both share the same Cortex-M0+ core, 64 MHz speed, 128 KB Flash, and 32-LQFP package. If your design needs a USB-C PD port, the G081 is the correct pick; if not, the G071 saves a small cost.

What is the equivalent of STM32G081KBT6?

Within the STM32G0 family, the STM32G071KBT6 is the closest functional equivalent minus the USB Type-C PD peripheral. The STM32L151CBU6A is a different architecture (Cortex-M3 at 32 MHz) with lower speed but more I/Os and a 1.8 V supply — it is not a pin-compatible drop-in but could serve a similar application role with a board spin.
