STMicroelectronics STM32F103VDH6TR

Overview

STM32F103VDH6TR from STMicroelectronics is a high-density performance-line Arm® Cortex®-M3 microcontroller featuring 384 KB Flash, 64 KB SRAM, USB 2.0 full-speed interface, CAN 2.0B controller, and triple 12-bit ADCs (21 channels, 1 µs conversion). It operates at up to 72 MHz with 1.25 DMIPS/MHz performance and supports industrial motor control, PLC I/O modules, and USB-CDC-based embedded gateways.

For engineers reviewing the STM32F103VDH6TR datasheet, STM32F103VDH6TR pinout, STM32F103VDH6TR application, or STM32F103VDH6TR equivalent, key selection criteria include Flash/SRAM size, USB+CAN dual-interface capability, 112 I/O count with 5 V tolerance, and LFBGA100 package suitability for space-constrained industrial PCB layouts.

Technical Context

This MCU integrates a single-core Cortex-M3 with tightly coupled NVIC, 12-channel DMA supporting concurrent ADC/DAC/USB transfers, and a flexible static memory controller (FSMC) enabling direct NOR/PSRAM/NAND interfacing. Its clock system combines 4–16 MHz external crystal support, factory-trimmed 8 MHz RC, and 40 kHz RC with RTC calibration.

The peripheral set includes two 12-bit DACs, three 12-bit ADCs with temperature sensor and triple-sample-and-hold, four 16-bit general-purpose timers with quadrature encoder input, two motor-control PWM timers with dead-time generation, and five USARTs with LIN/IrDA/ISO 7816 support - all mapped across 112 I/O pins with programmable pull-up/down and interrupt vectoring.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating temperature range for STM32F103VDH6TR?

The STM32F103VDH6TR is rated for industrial temperature range: –40 °C to +85 °C ambient, verified per datasheet Section 5.3.1. Thermal resistance (θ_JA) is 30 °C/W for LFBGA100 package on 4-layer PCB with 1 oz copper and 20% copper pour - derating required above 70 °C ambient in sealed enclosures.

Does STM32F103VDH6TR support USB device mode without external components?

Yes - it integrates a full-speed USB 2.0 transceiver with internal pull-up resistor control on PA12 (USB_DP). Only a 1.5 kΩ pull-up to 3.3 V on PA12 is required for device enumeration; no external PHY or resistors needed for basic CDC or HID class operation per Section 2.3.24 of DS5792.

How many independent PWM channels can be generated simultaneously?

Up to 28 independent PWM outputs: four 16-bit general-purpose timers (TIM2–TIM5) provide up to 4 channels each (16 total), plus two advanced-control timers (TIM1/TIM8) deliver 6 channels each (12 total), all with configurable polarity, dead-time, and synchronization - confirmed in Table 4 and Section 2.3.17 of DS5792 Rev 13.

Is the LFBGA100 package RoHS-compliant and lead-free?

Yes - STM32F103VDH6TR uses ECOPACK®-compliant LFBGA100 packaging with lead-free (Pb-free) terminations and halogen-free molding compound, certified per EU RoHS Directive 2011/65/EU and REACH SVHC regulations, as stated in Section 1.2 and Table 75 of DS5792 Rev 13.
