That clock rate puts it in the sweet spot for cost-sensitive control loops — fast enough to handle a 20 kHz PWM update with cycle-by-cycle current limit and a Modbus RTU stack running in the background, without needing a Cortex-M3 or M4. ## Peripherals and I/O — what connects where Thirty I/O lines in a 32-UFQFN 5x5 mm package — that is a high pin-to-area ratio, which helps on dense boards but demands careful fan-out routing. The exposed pad (UFQFPN) needs a thermal via stitch under the paddle to pull heat into the ground plane; without it, the junction temperature rises faster than the 125 °C limit allows at sustained 64 MHz operation. That removes the single-source risk for a design starting today — you are not locking into a soon-to-be-obsolete line.","metaTitle":"STM32G071KBU3 ARM Cortex-M0+ MCU, 64MHz, 128KB Flash","metaDescription":"STM32G071KBU3 32-bit MCU with 64MHz Cortex-M0+, 128KB Flash, 36KB RAM, -40 to 125°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","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":"STM32G071","Program Memory Size":"128KB (128K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~125°C(TA)","Supplier Device Package":"32-UFQFPN (5x5)","Voltage - Supply (Vcc/Vdd)":"1.7V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.2200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3acc4c90a212caed0ac76df97b7ae54a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32G071KBU3/alternatives.json"},"ai":{"faq":[{"question":"Can STM32G071KBU3 replace STM32G071KBU6?","answer":"The STM32G071KBU3 and STM32G071KBU6 share the same base product number STM32G071 and the same 32-UFQFPN 5x5 mm package, but the suffix difference may indicate a different temperature grade or other variant-specific parameter.
