Product details
Overview
STM32F103VDT6TR from STMicroelectronics is a high-density performance-line Arm® Cortex®-M3 microcontroller featuring 384 KB Flash, 64 KB SRAM, 72 MHz CPU frequency, USB 2.0 full-speed interface, and CAN 2.0B controller. It integrates three 12-bit ADCs (21 channels), two 12-bit DACs, 11 timers including motor-control PWM units with dead-time generation, and operates across –40°C to +85°C industrial temperature range. Used in motor control systems requiring real-time PWM coordination and dual communication bus redundancy.
For engineers reviewing the STM32F103VDT6TR datasheet, STM32F103VDT6TR pinout, STM32F103VDT6TR application, or STM32F103VDT6TR equivalent, key selection criteria include Flash/SRAM size matching, LQFP100 package compatibility, CAN+USB co-integration, 72 MHz deterministic timing, and industrial-grade thermal operation - all confirmed for this specific orderable variant.
Technical Context
This MCU implements a tightly coupled Arm Cortex-M3 core with Harvard bus architecture, supporting single-cycle multiplication and hardware divide. Its memory subsystem includes 384 KB of embedded Flash with error correction, 64 KB SRAM, and a flexible static memory controller (FSMC) supporting NOR/PSRAM/NAND with up to four chip selects.
The peripheral set is synchronized via APB1 (36 MHz) and APB2 (72 MHz) buses, enabling concurrent high-speed USB packet handling, CAN frame arbitration, and 1 µs ADC sampling - all managed by a 12-channel DMA controller with configurable priority levels and peripheral request mapping.

FAQ
What is the exact Flash and SRAM capacity of STM32F103VDT6TR?
STM32F103VDT6TR contains 384 KB of embedded Flash memory and 64 KB of SRAM. This is confirmed in ST's DS5792 Rev 13 datasheet Table 1 and Section 2.3.2, where "V" in the part number denotes the 384 KB Flash density variant within the STM32F103xD series.
Does STM32F103VDT6TR support USB and CAN simultaneously?
Yes. The device integrates a USB 2.0 full-speed interface (PA11/PA12) and a CAN 2.0B controller (PB8/PB9) that operate independently on separate clock domains. Both peripherals are active concurrently in run mode, verified in Section 2.3.24 and 2.3.23 of the datasheet.
What is the maximum operating frequency and associated power supply requirement?
The maximum CPU frequency is 72 MHz, requiring a 2.0–3.6 V VDD supply. At 72 MHz with all peripherals active, typical current consumption is 36 mA (DS5792 Table 14), and operation is guaranteed across the full industrial temperature range (–40°C to +85°C).
Is the LQFP100 package of STM32F103VDT6TR RoHS-compliant and lead-free?
Yes. STM32F103VDT6TR uses an ECOPACK®-compliant LQFP100 package, explicitly stated in the datasheet Features section and confirmed in ST's official product page and packaging documentation - fully lead-free and RoHS 2011/65/EU compliant.
