The exposed pad is not present on this QFP variant, so thermal dissipation goes through the leads — keep the copper pour on the board to help with junction temperature if running the core and peripherals near maximum.","metaTitle":"STM32F051R8T6 ARM Cortex-M0 MCU, 48 MHz, 64 KB Flash","metaDescription":"STMicroelectronics STM32F051R8T6 32-bit MCU with 48 MHz Cortex-M0 core, 64 KB Flash, 8 KB SRAM, 55 I/O, industrial temp -40°C to 85°C.","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":"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":"55","Core Processor":"ARM® Cortex®-M0","Package / Case":"64-LQFP","Product Status":"Active","Data Converters":"A/D 19x12b; 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 ~ 85°C (TA)","Voltage - Supply (Vcc/Vdd)":"2V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.5100","priceTiers":[{"qty":1,"price":"$4.51000","currency":"USD"},{"qty":10,"price":"$4.04700","currency":"USD"},{"qty":25,"price":"$3.82560","currency":"USD"},{"qty":160,"price":"$3.31544","currency":"USD"},{"qty":320,"price":"$3.14544","currency":"USD"},{"qty":480,"price":"$2.82240","currency":"USD"},{"qty":960,"price":"$2.38032","currency":"USD"},{"qty":2400,"price":"$2.26131","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/5b8222026032a8f6c67417def25d2d17.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F051R8T6/alternatives.json"},"ai":{"faq":[{"question":"Can STM32F051R8T6 be programmed using ST-Link/V2?","answer":"Yes, the STM32F0 series uses the standard SWD debug interface, which the ST-Link/V2 supports.
