ST's STM32G0 series is their mainstream low-cost platform, so volume allocation and lead times are generally stable through the authorized channel.","metaTitle":"STM32G031G4U6 ARM Cortex-M0+ MCU, 64 MHz, 16 KB Flash","metaDescription":"STMicroelectronics STM32G031G4U6 32-bit MCU with 64 MHz Cortex-M0+, 16 KB Flash, 8 KB RAM, 26 I/O, 1.7-3.6 V supply.","metaKeywords":null},"attributes":{"series":"STM32G0","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":"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, 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 17x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32G031","Program Memory Size":"16KB (16K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"28-UFQFPN (4x4)","Voltage - Supply (Vcc/Vdd)":"1.7V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.0600","priceTiers":[{"qty":1,"price":"$3.06000","currency":"USD"},{"qty":10,"price":"$2.74500","currency":"USD"},{"qty":25,"price":"$2.58960","currency":"USD"},{"qty":80,"price":"$2.20613","currency":"USD"},{"qty":230,"price":"$2.07152","currency":"USD"},{"qty":440,"price":"$1.81259","currency":"USD"},{"qty":945,"price":"$1.50185","currency":"USD"},{"qty":2940,"price":"$1.41240","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/9c76df672453926eff65e748ce93d981.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32G031G4U6/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between STM32G031G4U6 and STM32G031G8U6?","answer":"The STM32G031G8U6 doubles the Flash to 64 KB (64K x 8) while keeping the same 28-UFQFPN package, 26 I/O, and 64 MHz Cortex-M0+ core.
