This part is the mainstream choice for motor drives, industrial PLCs, building automation, and any application needing a balanced mix of processing headroom, memory, and peripheral integration without moving to a higher-cost family. 768 KB Flash (768K x 8) and 96 KB SRAM (96K x 8). ## 80 I/O and the peripheral set — what the motor-control PWM and DMA mean for your BOM With 80 I/Os in a 100-pin LQFP, you have enough pins to drive a parallel LCD, interface to an external memory bus, and still have room for a dozen sensor inputs and actuator outputs. The motor-control PWM timer with complementary outputs and dead-time insertion is a hardware feature that offloads the core — no software bit-banging for three-phase inverter control. The DMA engine moves ADC results, UART data, and SPI frames without CPU intervention, which keeps the 72 MHz core free for the control algorithm. The 16-channel 12-bit ADC samples at up to 1 µs per channel, adequate for current sensing in motor drives at typical PWM frequencies. The internal POR/PVD circuits handle power-on reset and supply-drop detection, saving an external supervisor in many designs.","metaTitle":"STM32F103VFT6 STM32F1 ARM Cortex-M3 MCU, 72 MHz","metaDescription":"STMicroelectronics STM32F103VFT6 32-bit MCU with ARM Cortex-M3 core at 72 MHz, 768 KB Flash, 96 KB RAM, 80 I/O, CAN/USB/SPI, -40 to 85°C.","metaKeywords":null},"attributes":{"series":"STM32F1","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"72MHz","Series":"STM32F1","Package":"Tray","RAM Size":"96K 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":"768KB (768K 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":"$11.9900","priceTiers":[{"qty":1,"price":"$11.99000","currency":"USD"},{"qty":10,"price":"$11.02100","currency":"USD"},{"qty":25,"price":"$10.56440","currency":"USD"},{"qty":90,"price":"$9.30800","currency":"USD"},{"qty":270,"price":"$8.85119","currency":"USD"},{"qty":450,"price":"$8.28013","currency":"USD"},{"qty":990,"price":"$7.59489","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/1e0a2899638e8adeb34943c703bd9a9b.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F103VFT6/alternatives.json"},"ai":{"faq":[{"question":"What are equivalent parts to STM32F103VFT6?","answer":"Within the STM32F1 series, the STM32F103VET6 (512 KB Flash, 64 KB RAM) is a drop-in pin-compatible alternative if you can accept less memory.
