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. ## Connectivity and peripherals — what's on the die ## Sourcing and supply","metaTitle":"ST STM32G081CBT6 ARM Cortex-M0+ MCU, 64 MHz, 128 KB Flash","metaDescription":"STMicroelectronics STM32G081CBT6 32-bit MCU with 64 MHz Cortex-M0+ core, 128 KB Flash, 36 KB RAM, USB Type-C PD, 48-LQFP.
