The 64K x 8 SRAM supports moderate data buffering and a real-time OS footprint. If your firmware image is pushing past 300 KB, this part keeps you out of external memory territory. ## 100-LQFP — layout and reflow considerations The 100-LQFP (14x14 mm) package is a standard industrial MCU footprint. The 0.5 mm pitch requires a controlled impedance stackup if you're routing USB or CAN at full speed, but the pin-to-pin spacing is forgiving for two-layer boards with careful trace routing. No exposed pad — all thermal dissipation goes through the leadframe, so keep the ambient airflow in mind if the part is running near 105°C with most I/O switching. ST lists this part as Active.","metaTitle":"STM32F103VDT7 ARM Cortex-M3 MCU, 72MHz, 384KB Flash","metaDescription":"STMicroelectronics STM32F103VDT7 32-bit ARM Cortex-M3 MCU, 72MHz core, 384KB Flash, 64K x 8 RAM, 80 I/O, -40 to 105°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, Motor Control PWM, PDR, POR, PVD, PWM, Temp Sensor, WDT","Connectivity":"CANbus, I²C, IrDA, LINbus, SPI, UART/USART, USB","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":"STM32F103","Program Memory Size":"384KB (384K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 105°C (TA)","Supplier Device Package":"100-LQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"2V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.0588","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/72e2217711e2aa33719949448f146656.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F103VDT7/alternatives.json"},"ai":{"faq":[{"question":"What is the core processor of STM32F103VDT7?","answer":"The core processor is an ARM Cortex-M3, 32-bit single-core, running at 72 MHz."},{"question":"What are the differences between STM32F103VDT7 and STM32F103VET7?","answer":"The STM32F103VET7 is a higher-density variant in the same package and pinout, with 512 KB Flash and 64K x 8 SRAM.
