This is a 28-lead QFN with an exposed pad underneath. The 4x4 mm body has low thermal mass, so it reflows fast — preheat the board to 150°C, then hit the package with hot air at 320°C for about 20 seconds. The pad is small enough that solder bridging between the perimeter leads is unlikely if your stencil aperture is right. MSL 3 out of the bag — bake at 125°C for 24 hours if the moisture barrier bag has been open longer than the floor-life window. ST lists the STM32G071GBU3 as Active.","metaTitle":"STM32G071GBU3 ARM Cortex-M0+ MCU, 64 MHz, 128 KB Flash","metaDescription":"STMicroelectronics STM32G071GBU3 32-bit MCU, ARM Cortex-M0+ at 64 MHz, 128 KB Flash, 36K x 8 RAM, -40°C to 125°C, 28-UFQFPN.","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","Mounting Type":"Surface Mount","Number of I/O":"26","Core Processor":"ARM® Cortex®-M0+","Package / Case":"28-UFQFN","Product Status":"Active","Data Converters":"A/D 12x12b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32G071","Program Memory Size":"128KB (128K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~125°C(TA)","Supplier Device Package":"28-UFQFPN (4x4)","Voltage - Supply (Vcc/Vdd)":"1.7V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.1600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3acc4c90a212caed0ac76df97b7ae54a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32G071GBU3/alternatives.json"},"ai":{"faq":[{"question":"Can STM32G071GBU3 replace STM32G071KBU3?","answer":"The STM32G071KBU3 is a pin-compatible variant in the same STM32G071 family, differing primarily in Flash and RAM density. The STM32G071GBU3 has 128 KB Flash and 36K x 8 RAM; the KBU3 variant carries 64 KB Flash. If your firmware fits the smaller Flash, the KBU3 is a drop-in replacement.
