概述

Description

STM32F103VDT7 is a 32‑bit microcontroller from STMicroelectronics in the STM32F1 family. It uses an ARM Cortex‑M3 core and runs up to 72 MHz. The “VDT7” suffix denotes the device/package variant (100‑pin LQFP in many listings) and related temperature range; exact pinout and memory vary by exact part, so check the datasheet for specifics.
Key features (typical of F1 devices):
- Cortex‑M3 core, up to 72 MHz
- Flash and RAM sizes vary by variant (hundreds of KB Flash, tens of KB RAM on many F1 parts)
- Rich peripherals: multiple USART/UART, SPI, I2C, CAN; USB FS on many variants; 12‑bit ADCs, timers/PWM, DMA, RTC
- Diverse power modes and clocks for flexibility
Development and tooling:
- Supported by STM32CubeMX/CubeIDE, HAL/LL libraries
- Debug with ST‑LINK or similar debuggers
Applications: motor control, data acquisition, sensors, industrial/consumer embedded systems.
Note: For exact specs (flash/RAM, USB yes/no, pins), refer to the STM32F103VDT7 datasheet and reference manual.

Features

STM32F103VDT7 features (concise):
- Core: 32-bit ARM Cortex-M3, up to 72 MHz.
- Memory: 128 KB Flash, 20 KB SRAM.
- Package: 100-pin LQFP (VDT7).

- Peripherals: USB 2.0 Full‑Speed device, CAN 2.0B, SPI (2), I2C (2), USART (3).
- Timers: TIM1 (16‑bit advanced), TIM2–TIM5 (general purpose).
- ADC/DAC: 12‑bit ADC with up to 12 channels (no DAC).
- DMA: Multi-channel DMA controller.
- Power: 2.0–3.6 V supply; operating temp typically -40 to 85°C.
- Low power: Sleep, Stop, Standby modes; RTC support.
- Debug/Boot: SWD/JTAG debug; in-system/boot from Flash.
- Other: Interrupt controller (NVIC), multiple external interrupts, watchdogs.
Note: exact RAM/ peripheral counts may vary slightly by subfamily; VD(T)7 denotes the 100-pin package variant of the F103 line.
