Product details

The STM32G081CBT6 is a 32-bit ARM Cortex-M0+ MCU from ST's STM32G0 series, clocked at 64 MHz. It carries 128 KB of Flash and 36 KB of RAM, enough for a USB-C Power Delivery controller or a multi-protocol sensor hub. The integrated USB Type-C PHY with Power Delivery support saves an external controller chip — that's a real BOM consolidation move for a compact board.

Lifecycle — EOL hot, plan the migration

This part carries an EOL hot lifecycle status. That means ST has announced end-of-life — the last-time-buy window is active or closing. If you're qualifying a new design, look at the STM32G0 series successors or a pin-compatible sibling in the same 48-LQFP footprint. For existing BOM lines, secure your last-time-buy quantities now; after the LTB closes, supply moves to surplus and broker channels.

Sourcing and supply

Frequently asked questions

Where can I buy STM32G081CBT6 and get a price?

We source the STM32G081CBT6 to order through independent distribution. Submit an RFQ for current availability and pricing — no stock count or price is listed here, but we confirm both at quote time.

What is the closest pin-compatible alternative to STM32G081CBT6?

A pin-compatible sibling in the same 48-LQFP footprint would be another STM32G0 series MCU with the same package and pinout, such as the STM32G071CBT6. Verify the peripheral set and Flash/RAM size against your firmware requirements before swapping.

What is STM32G081CBT6's listed speed?

The STM32G081CBT6 runs at 64 MHz on its ARM Cortex-M0+ core.

What series is STM32G081CBT6 part of?

It belongs to the STM32G0 series.

What compliance documentation does ST provide for STM32G081CBT6?

ST provides RoHS and REACH compliance documentation for this part. The 48-LQFP package is lead-free and RoHS-compliant per ST's standard declarations.
