The 64 MHz clock gives it a comfortable margin over the 32 MHz STM32L151CBU6A for code that needs tighter loop execution — think PID updates at 20 kHz or polling multiple UART channels at 115200 baud without dropping bytes. ST lists this part as Active and current-production. No last-time-buy window has been announced, and the STM32G0 series is a mainstream portfolio line with long-term supply commitment. ## Industrial temp grade and compact package The 32-UFQFN package with exposed pad (5x5 mm footprint) saves board area and, with proper via stitching under the paddle, keeps the junction cool even at full 64 MHz throughput. ## Peripherals and connectivity for mixed-signal control On-chip peripherals include an 18-channel 12-bit SAR ADC, brown-out detect, DMA, I²S, PWM, and a full set of watchdog timers.","metaTitle":"STM32G031K8U6 ARM Cortex-M0+ MCU, 64 MHz, 64 KB Flash","metaDescription":"STMicroelectronics STM32G031K8U6 32-bit MCU with 64 MHz Cortex-M0+, 64 KB Flash, 8 KB RAM, industrial temp -40°C to 85°C.","metaKeywords":null},"attributes":{"series":"STM32G0","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"64MHz","Series":"STM32G0","Package":"Tray","RAM Size":"8K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, I²S, POR, PWM, WDT","Connectivity":"I²C, IrDA, LINbus, SPI, SmartCard, 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 18x12b SAR","Oscillator Type":"External, Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32G031","Program Memory Size":"64KB (64K 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":"$2.8600","priceTiers":[{"qty":1,"price":"$2.86000","currency":"USD"},{"qty":10,"price":"$2.57100","currency":"USD"},{"qty":25,"price":"$2.42560","currency":"USD"},{"qty":80,"price":"$2.06675","currency":"USD"},{"qty":230,"price":"$1.94061","currency":"USD"},{"qty":490,"price":"$1.69804","currency":"USD"},{"qty":980,"price":"$1.40695","currency":"USD"},{"qty":2450,"price":"$1.30991","currency":"USD"},{"qty":4900,"price":"$1.26140","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/8450e95e2a0cc61f9ebc6d39a13e7004.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32G031K8U6/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between STM32G031K8U6 and STM32G031K6U6?","answer":"The difference is Flash density: STM32G031K8U6 has 64 KB, while the K6 variant has 32 KB.
