STM32F103VEH6TR

STM32F103VEH6TR is a 32‑bit ARM Cortex‑M3 microcontroller from ST’s STM32F1 family. It runs a Cortex‑M3 core up to 72 MHz and integrates a broad set of peripherals for embedded control: GPIOs, timers (TIMx), ADCs (12‑bit), USART/UART, SPI, I2C, CAN, USB Full‑Speed on applicable variants, RTC, watchdogs, and DMA channels. It operates from 2.0 to 3.6 V and is provided in a 100‑pin LQFP package with tape‑and‑reel packaging (TR). Memory size (Flash/RAM) and exact peripherals depend on the specific silicon revision within the VE family, so consult the datasheet for precise figures. Typical uses include motor control, USB devices, data acquisition, and general embedded control. Development is supported by STM32CubeMX for configuration and the HAL or Standard Peripheral Library, with toolchains such as Keil MDK, IAR, or GCC.

Equivalent ST parts to STM32F103VEH6TR are:
- STM32F103VET6
- STM32F103ZET6
These are the closest ST equivalents (same Cortex-M3, 100-pin LQFP, 72 MHz, similar flash/RAM). The TR suffix is only packaging (tape-and-reel). For exact cross-references and packaging, use ST’s product cross-reference tool.
