The POR (power-on reset) peripheral is built in, so external reset supervision is optional unless you need a precise brown-out threshold. For the ADC, a clean 3.3 V analog supply (VDDA) is recommended; the datasheet typical noise figures assume a decoupled analog rail.","metaTitle":"STM32F051K8U7TR ARM Cortex-M0 MCU, 48 MHz, 64 KB Flash","metaDescription":"STMicroelectronics STM32F051K8U7TR 32-bit ARM Cortex-M0 MCU, 48 MHz, 64 KB Flash, 8K x 8 RAM, 27 I/O, -40 to 105°C, 32-UFQFPN.","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":"Tape & Reel (TR) Cut Tape (CT)","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":"27","Core Processor":"ARM® Cortex®-M0","Package / Case":"32-UFQFN Exposed Pad","Product Status":"Active","Data Converters":"A/D 13x12b; D/A 1x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32F051","Program Memory Size":"64KB (64K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 105°C (TA)","Supplier Device Package":"32-UFQFPN (5x5)","Voltage - Supply (Vcc/Vdd)":"2V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.0100","priceTiers":[{"qty":1,"price":"$4.01000","currency":"USD"},{"qty":10,"price":"$3.59800","currency":"USD"},{"qty":25,"price":"$3.40160","currency":"USD"},{"qty":100,"price":"$2.94790","currency":"USD"},{"qty":250,"price":"$2.79676","currency":"USD"},{"qty":500,"price":"$2.50954","currency":"USD"},{"qty":1000,"price":"$2.11648","currency":"USD"},{"qty":3000,"price":"$2.01065","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/5b8222026032a8f6c67417def25d2d17.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F051K8U7TR/alternatives.json"},"ai":{"faq":[{"question":"What is the flash memory size of STM32F051K8U7TR?","answer":"64 KB (64K x 8) of Flash program memory, paired with 8K x 8 of SRAM."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32F051K8U7TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32F051K8U7TR when reusing this data.
