The peripheral set includes DMA, motor-control PWM, a temperature sensor, and a watchdog timer — enough to implement a sensor-fusion node or a brushless DC motor drive with a single chip. The 16-channel 12-bit ADC samples at up to 1 µs per channel, adequate for current sensing in a motor phase loop or for reading a bank of analog sensors. The dual 12-bit DAC can generate analog setpoints or audio waveforms without an external converter. ST continues to manufacture this part, and there is no end-of-life notification or last-time-buy window on the horizon. ## Supply range and package — design-in notes The internal oscillator reduces external component count, though a precision crystal can be added for USB or CAN timing accuracy.","metaTitle":"STM32F103VGT6 ARM Cortex-M3 MCU, 72MHz, 1MB Flash, 100-LQFP","metaDescription":"STMicroelectronics STM32F103VGT6 32-bit MCU: 72MHz ARM Cortex-M3 core, 1MB Flash, 96KB SRAM, 80 I/O, -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":"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":"1MB (1M 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":"$14.3300","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/1e0a2899638e8adeb34943c703bd9a9b.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F103VGT6/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between STM32F103VGT6 and STM32F103VET6?","answer":"The STM32F103VGT6 has 1 MB of Flash memory, while the STM32F103VET6 has 512 KB.
