For a control loop or sensor-fusion task, that clock rate translates to roughly 64 DMIPS — enough to handle a 10 kHz PID loop with margin for communications overhead. The flash wait state needs configuring at this speed; the datasheet recommends one wait state above 24 MHz, so the boot code should set it before the PLL locks. ## Memory map: 64 KB Flash, 8 KB SRAM Program memory is 64 KB of Flash, organized as 64 K x 8. The 8 KB SRAM (8 K x 8) is modest but adequate for a single control loop, a small RTOS tick, and a few communication buffers. If the firmware needs a large lookup table or a display frame buffer, the 64 KB Flash boundary is the hard limit — no external memory interface on this part. The Flash endurance is rated for the STM32G0 family standard; sector erase granularity is 2 KB, which matters when planning an OTA update region. At 64 MHz the active current draw is typically in the 10–15 mA range, though the exact figure depends on peripheral usage. ## Package and I/O count All I/O are 5 V tolerant on this family, which simplifies level-shifting when interfacing to 5 V legacy peripherals. The 1.7 V minimum supply holds across the full temperature range, so battery-powered outdoor sensors can run down to the cell's end-of-life voltage without a regulator dropout.","metaTitle":"ST STM32G031C8T6 ARM Cortex-M0+ MCU, 64 MHz, 64 KB Flash","metaDescription":"STMicroelectronics STM32G031C8T6 32-bit MCU with 64 MHz Cortex-M0+ core, 64 KB Flash, 8 KB SRAM, 44 I/O, 12-bit ADC, 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":"44","Core Processor":"ARM® Cortex®-M0+","Package / Case":"48-LQFP","Product Status":"Active","Data Converters":"A/D 19x12b 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":"48-LQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"1.7V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.0200","priceTiers":[{"qty":1,"price":"$3.02000","currency":"USD"},{"qty":10,"price":"$2.70800","currency":"USD"},{"qty":25,"price":"$2.56000","currency":"USD"},{"qty":80,"price":"$2.21863","currency":"USD"},{"qty":250,"price":"$2.10488","currency":"USD"},{"qty":500,"price":"$1.88868","currency":"USD"},{"qty":1000,"price":"$1.59287","currency":"USD"},{"qty":2500,"price":"$1.51323","currency":"USD"},{"qty":5000,"price":"$1.45634","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/8450e95e2a0cc61f9ebc6d39a13e7004.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32G031C8T6/alternatives.json"},"ai":{"faq":[{"question":"What is the maximum operating frequency of STM32G031C8T6?","answer":"The STM32G031C8T6 runs at 64 MHz from the internal PLL, with the core clock sourced from the HSI or HSE oscillator."},{"question":"What package type does STM32G031C8T6 use?","answer":"It comes in a 48-LQFP (7x7 mm) surface-mount package with 44 I/O."},{"question":"What are the alternatives to STM32G031C8T6?","answer":"A functional peer is the STM32L151CBU6A, which uses an ARM Cortex-M3 core at 32 MHz and adds USB connectivity, but runs at half the clock speed and has a narrower supply range (1.8 V minimum).
