Description
STM32F103VDT7 is a 32‑bit MCU from STMicroelectronics in the STM32F1 family. Key points:
- Core: ARM Cortex‑M3 up to 72 MHz.
- Package: 100‑pin LQFP (VDT7 variant); memory size varies by device (hundreds of KB of flash, tens of KB of RAM are common in VD devices).
- Peripherals: USB 2.0 Full‑Speed, CAN, multiple USART/SPI/I2C, up to 16‑channel 12‑bit ADC, timers (including advanced timers), and PWM. Some variants include DAC.
- Power: operates around 2.0–3.6 V with several low‑power modes.
- Development: strong ecosystem (HAL/LL drivers in STM32CubeMX, wide IDE/tool support).
- Use cases: general purpose MCU for motor control, USB devices, embedded industrial/applications.
Note: exact memory sizes, peripheral counts, and features depend on the specific VD7 variant. Check the official datasheet and reference manual for precise specs.
