At 64 MHz the Cortex-M0+ delivers single-cycle I/O and fast interrupt response, suited for real-time control loops and communication protocol handling. The 128 KB Flash is sized for mid-complexity firmware stacks, including USB Type-C Power Delivery and multiple serial interfaces (I2C, SPI, UART/USART, LIN, IrDA). That means no last-time-buy pressure and full manufacturer support for new designs. For dual-sourcing resilience, the STM32G0 family includes pin-compatible density variants — qualify the alternate now rather than single-source the BOM line. ## Package and power delivery Supply decoupling should follow the reference design: a 100 nF ceramic per VDD pair plus a 4.7 µF bulk capacitor on the main rail.","metaTitle":"STM32G081CBU6 ARM Cortex-M0+ MCU, 64 MHz, 128 KB Flash","metaDescription":"STMicroelectronics STM32G081CBU6 32-bit MCU with ARM Cortex-M0+ core, 64 MHz speed, 128 KB Flash, 36K x 8 RAM, 1.7 V to 3.6 V supply, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"64MHz","Series":"STM32G0","Package":"Tray","RAM Size":"36K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, I2S, POR, PWM, WDT","Connectivity":"HDMI-CEC, I2C, IrDA, LINbus, SPI, UART/USART, USB Type-C™ (Power Delivery)","Mounting Type":"Surface Mount","Number of I/O":"44","Core Processor":"ARM® Cortex®-M0+","Package / Case":"48-UFQFN Exposed Pad","Product Status":"Active","Data Converters":"A/D 17x12b; D/A 2x12b","Oscillator Type":"External, Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32G081","Program Memory Size":"128KB (128K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"48-UFQFPN (7x7)","Voltage - Supply (Vcc/Vdd)":"1.7V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.2176","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ff1515e19cd6d6de50e6dbfd9e8fe5bc.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32G081CBU6/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to STM32G081CBU6?","answer":"Within the STM32G0 series, the STM32G071CB (same package and pinout) offers a similar peripheral set with slightly different memory options.
