Connectivity covers CANbus, I²C, SPI, UART/USART, USB, IrDA, and LINbus — enough for a multi-protocol field-device or a sensor hub. The data-converter block provides 16-channel 12-bit ADC and two 12-bit DAC channels. ## Temperature grade and supply — industrial range, single-rail operation Supply range is 2.0 V to 3.6 V on Vcc/Vdd, allowing a single 3.3 V rail or a 2.5 V battery-backed design. The 100-LQFP package and standard STM32F1 pinout make it straightforward to dual-source with other STM32F103VE variants if needed — the laser etch and date-code should match ST's factory marking conventions, something a buyer should verify on incoming inspection to avoid gray-market re-marked stock.","metaTitle":"STM32F103VET7 STM32F1 ARM Cortex-M3 MCU, 72 MHz","metaDescription":"STMicroelectronics STM32F103VET7 32-bit MCU with ARM Cortex-M3 core at 72 MHz, 512 KB Flash, 64 KB SRAM, 80 I/O, 100-LQFP.","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":"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":"512KB (512K 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":"$11.5900","priceTiers":[{"qty":1,"price":"$11.59000","currency":"USD"},{"qty":10,"price":"$10.64800","currency":"USD"},{"qty":25,"price":"$10.20680","currency":"USD"},{"qty":90,"price":"$8.99311","currency":"USD"},{"qty":270,"price":"$8.55170","currency":"USD"},{"qty":450,"price":"$7.99998","currency":"USD"},{"qty":990,"price":"$7.33791","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/72e2217711e2aa33719949448f146656.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F103VET7/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to the STM32F103VET7?","answer":"Within the STM32F103VE density tier, other devices in the same 100-pin LQFP footprint (such as the STM32F103VET6) share the same pinout and peripheral map, differing mainly in temperature grade or minor feature sets.
