The 48-LQFP package (7x7 mm) gives 39 accessible I/O, enough for a modest sensor array, a small TFT display, or a CAN node. ## Peripheral set and power rail fit ## Industrial temperature grade, no automotive qualification For factory automation, motor drives, and HVAC controllers where the ambient stays below 85°C, the grade is a direct fit. ## Memory sizing and firmware staging A bare-metal control loop, a simple Modbus RTU slave, or a sensor-fusion algorithm with a few hundred bytes of state fits. If the application needs a TCP/IP stack, a GUI library, or over-the-air update staging, the designer should look at the STM32F103 or STM32F4 series with larger Flash and SRAM. The 4 KB SRAM is the real constraint — runtime heap and stack must be carefully sized, and DMA buffers cut into the available pool.","metaTitle":"ST STM32F031C6T6 ARM Cortex-M0 MCU, 48 MHz, 32 KB Flash","metaDescription":"STM32F031C6T6 32-bit MCU from STMicroelectronics, ARM Cortex-M0 core at 48 MHz, 32 KB Flash, 4 KB SRAM, 39 I/O, 48-LQFP.","metaKeywords":null},"attributes":{"series":"STM32F0","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"48MHz","Series":"STM32F0","Package":"Tray","RAM Size":"4K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"DMA, I²S, POR, PWM, WDT","Connectivity":"I²C, IrDA, LINbus, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"39","Core Processor":"ARM® Cortex®-M0","Package / Case":"48-LQFP","Product Status":"Active","Data Converters":"A/D 13x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32F031","Program Memory Size":"32KB (32K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"48-LQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"2V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.4500","priceTiers":[{"qty":1,"price":"$3.45000","currency":"USD"},{"qty":10,"price":"$3.09900","currency":"USD"},{"qty":25,"price":"$2.92960","currency":"USD"},{"qty":80,"price":"$2.53888","currency":"USD"},{"qty":250,"price":"$2.40868","currency":"USD"},{"qty":500,"price":"$2.16130","currency":"USD"},{"qty":1000,"price":"$1.82279","currency":"USD"},{"qty":2500,"price":"$1.73165","currency":"USD"},{"qty":5000,"price":"$1.66655","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/7127f169a82fed95ea2bf9d385a9c5f9.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F031C6T6/alternatives.json"},"ai":{"faq":[{"question":"What is the STM32F031C6T6's core clock speed?","answer":"The core processor runs at 48 MHz, which is the maximum clock for the ARM Cortex-M0 in this STM32F0 variant. The firmware engineer must set the flash wait state to 1 when the system clock exceeds 24 MHz, or the part will fault on the first instruction fetch from Flash."},{"question":"Can I use the STM32L151CBU6A as a direct replacement for the STM32F031C6T6?","answer":"No, the STM32L151CBU6A is not a pin-compatible or direct second-source. It uses an ARM Cortex-M3 core (vs M0), runs at 32 MHz (vs 48 MHz), and comes in a UFQFPN-48 package (vs LQFP-48). The peripheral mix differs — the L151 adds USB and 2x12-bit DAC but removes I²S. A board redesign and firmware port would be required; the two parts are not drop-in interchangeable."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32F031C6T6","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32F031C6T6 when reusing this data.
