Product details
Overview
STM32F103VET6TR from STMicroelectronics is a high-density performance-line Arm® Cortex®-M3 microcontroller featuring 512 KB Flash, 64 KB SRAM, USB 2.0 full-speed interface, CAN 2.0B controller, and three 12-bit ADCs with 21 channels-used in industrial motor control systems requiring real-time PWM generation, analog sensing, and fieldbus communication.
For engineers reviewing the STM32F103VET6TR datasheet, STM32F103VET6TR pinout, STM32F103VET6TR application, or STM32F103VET6TR equivalent, key selection criteria include Flash/SRAM capacity, 72 MHz CPU frequency, 112 I/O count, USB/CAN dual-interface support, and LQFP100 package compatibility for PCB layout and thermal management.
Technical Context
The device integrates an Arm Cortex-M3 core running at up to 72 MHz with single-cycle multiplication and hardware division, coupled with nested vectored interrupt controller (NVIC) supporting 84 interrupt channels. Its memory subsystem includes 512 KB on-chip Flash with error correction and 64 KB SRAM, plus a flexible static memory controller (FSMC) supporting NOR/PSRAM/NAND and CompactFlash.
Peripheral architecture features three independent 12-bit ADCs (1 µs conversion, triple-sample-and-hold), two 12-bit DACs, 12-channel DMA, and 13 communication interfaces-including 5 USARTs, 3 SPIs (two with I2S), 2 I2C, USB 2.0 FS, CAN 2.0B, and SDIO-enabling concurrent high-bandwidth data acquisition, motor control, and host connectivity.

FAQ
What is the maximum operating frequency and associated power consumption in Run mode?
The STM32F103VET6TR operates at up to 72 MHz with typical active current of 36 mA at 72 MHz, 3.3 V, and 25°C when executing from Flash with all peripherals disabled. Measured values scale linearly with clock frequency and voltage; full peripheral activation increases current by ≤12 mA depending on enabled modules.
Does this MCU support USB device enumeration without external components?
Yes - the integrated USB 2.0 full-speed transceiver includes internal pull-up resistors on D+ and requires only a standard USB Type-A connector and ESD protection diodes. No external PHY, oscillator, or termination resistors are needed for CDC, HID, or MSC class implementations.
How many independent PWM outputs can be generated simultaneously?
Up to 16 independent PWM signals can be generated: four 16-bit general-purpose timers provide up to 16 channels (4 per timer), and two motor-control timers add six complementary outputs with programmable dead-time. All channels are fully configurable via TIMx_CCMR registers and support center-aligned mode.
Is the LQFP100 package RoHS-compliant and lead-free?
Yes - the STM32F103VET6TR uses an ECOPACK®-compliant LQFP100 package with lead-free terminations and halogen-free molding compound. It meets EU RoHS Directive 2011/65/EU and JEDEC J-STD-020 moisture sensitivity level MSL3 (floor life: 168 hours at 30°C/60% RH).
