It comes in a 100-LQFP package (14x14 mm) with 80 general-purpose I/Os, making it a mid-density workhorse for industrial control, motor drives, and embedded systems that need a balanced mix of processing throughput and peripheral integration.
Peripheral set and connectivity — what is on the chip
On-chip peripherals include DMA, multiple PWM channels (including motor-control PWM), a temperature sensor, and voltage supervisors (PDR, POR, PVD). 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.
