That is enough for a basic motor current loop or a sensor fusion filter, but if you need floating-point or heavy DSP, step up to the Cortex-M4 siblings. That means you can run the MCU from a single 1.8 V rail (common in battery-powered designs) or from a 3.3 V rail (standard in industrial 24 V systems with a regulator). The dual-range also allows level-shifting-free connection to 1.8 V peripherals. Dropout on the internal regulator is not specified here, but the 1.65 V minimum gives about 150 mV headroom on a 1.8 V supply — tight, so keep the rail clean. The 48-UFQFN package with exposed pad helps junction-to-ambient thermal performance, but at 85°C ambient the internal regulator derates — keep the I/O current per pin under the datasheet limit (not repeated here) to stay inside the SOA. For dual-sourcing resilience, the STM32F0 series has pin-compatible density variants — the STM32F058C6 (32 KB Flash) and STM32F058R8 (64 KB Flash, 64-pin) — but no official second source outside ST.","metaTitle":"STM32F058C8U6 ARM Cortex-M0 MCU, 48 MHz, 64 KB Flash","metaDescription":"STMicroelectronics STM32F058C8U6 32-bit MCU with 48 MHz Cortex-M0 core, 64 KB Flash, 8K x 8 RAM, industrial temp -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"48MHz","Series":"STM32F0","Package":"Tray","RAM Size":"8K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"DMA, I2S, POR, PWM, WDT","Connectivity":"HDMI-CEC, I2C, IrDA, LINbus, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"38","Core Processor":"ARM® Cortex®-M0","Package / Case":"48-UFQFN Exposed Pad","Product Status":"Active","Data Converters":"A/D 13x12b; D/A 1x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32F058","Program Memory Size":"64KB (64K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"48-UFQFPN (7x7)","Voltage - Supply (Vcc/Vdd)":"1.65V ~ 1.95V, 1.65V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.0538","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9309b175f3e411804b84eed58ea37e31.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F058C8U6/alternatives.json"},"ai":{"faq":[{"question":"What is the flash memory size of STM32F058C8U6?","answer":"That is enough for moderate firmware with a real-time OS, communication stacks, and application logic, but not for large GUI or file-system images."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32F058C8U6","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32F058C8U6 when reusing this data.
