The 30 I/O lines in the 32-UFQFN package keep the board area tight for space-constrained designs like sensor nodes or motor-control interfaces. Brown-out detect and POR are integrated, so the reset supervisor on the BOM can often be dropped. ## Analog peripherals and connectivity Thirteen 12-bit ADC channels and two 12-bit DAC channels handle multi-sensor acquisition and analog output without external converters. The connectivity set — I²C, SPI, UART/USART with LIN and IrDA, plus USB and HDMI-CEC — covers the common industrial and consumer bus requirements. No last-time-buy window to track, no end-of-life clock running.","metaTitle":"STM32G081KBU6 ARM Cortex-M0+ MCU, 64MHz, 128KB Flash","metaDescription":"STM32G081KBU6 32-bit MCU from STMicroelectronics: 64MHz Cortex-M0+, 128KB Flash, 36KB SRAM, 30 I/O, -40 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","Mounting Type":"Surface Mount","Number of I/O":"30","Core Processor":"ARM® Cortex®-M0+","Package / Case":"32-UFQFN Exposed Pad","Product Status":"Active","Data Converters":"A/D 13x12b; D/A 2x12b","Oscillator Type":"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":"32-UFQFPN (5x5)","Voltage - Supply (Vcc/Vdd)":"1.7V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.9700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ff1515e19cd6d6de50e6dbfd9e8fe5bc.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32G081KBU6/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to STM32G081KBU6?","answer":"The STM32G071KBU6 is the closest pin-compatible sibling within the same STM32G0 family. The G081 adds a second DAC channel and a wider set of peripherals versus the G071, but the footprint and pinout match, making it a drop-in swap for designs that need the extra analog channel."},{"question":"What is the difference between STM32G081KBU6 and STM32G031KBU6?","answer":"The STM32G031KBU6 runs at a lower core speed (64 MHz vs 64 MHz — same clock, but the G031 lacks the second DAC, has fewer ADC channels, and less SRAM. The G081's 36 KB SRAM and 13 ADC channels versus the G031's smaller memory and 12 ADC channels make the G081 the better fit for sensor-heavy or data-buffering applications."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32G081KBU6","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32G081KBU6 when reusing this data.
