It is a QFP, so it is reworkable with hot air if you have a fine nozzle and steady hands — will it survive the hot air? Yes, but pre-bake the part if the tray has been open past MSL floor life. The exposed pad on this package is a thermal and electrical ground connection; make sure your PCB footprint includes a via-stitched thermal pad under the package to pull heat into the inner ground plane. ## Supply range and power-on behaviour The supply range is 2.0 V to 3.6 V, which covers both 3.3 V and 2.5 V logic rails. The internal POR (Power-On Reset) and voltage detect peripherals mean you can skip an external supervisor in many designs. The internal oscillator is available, but for USB operation you will want an external crystal — the internal RC does not meet the USB clock tolerance over temperature.","metaTitle":"STM32F105VCT6V ARM Cortex-M3 MCU, 72 MHz, 256 KB Flash","metaDescription":"STMicroelectronics STM32F105VCT6V 32-bit MCU with ARM Cortex-M3 core at 72 MHz, 256 KB Flash, 64 KB SRAM, USB OTG, CAN, industrial temp range -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":"72MHz","Series":"STM32F1","Package":"Tray","RAM Size":"64K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"DMA, POR, PWM, Voltage Detect, WDT","Connectivity":"CANbus, I²C, IrDA, LINbus, SPI, UART/USART, USB OTG","Mounting Type":"Surface Mount","Number of I/O":"80","Core Processor":"ARM® Cortex®-M3","Package / Case":"100-LQFP","Product Status":"Active","Data Converters":"A/D 16x12b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32F105","Program Memory Size":"256KB (256K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"100-LQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"2V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$9.8692","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/813271393bd0544f247ae965ea1bf2b0.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F105VCT6V/alternatives.json"},"ai":{"faq":[{"question":"Does STM32F105VCT6V support USB OTG?","answer":"Yes.
