Product details
Overview
STM32F072VBT6TR from STMicroelectronics is a 32-bit Arm® Cortex®-M0 microcontroller in LQFP100 package, operating up to 48 MHz with 128 KB Flash and 16 KB SRAM. It integrates crystal-less USB 2.0 FS, CAN 2.0B, one 12-bit ADC (16-channel, 1 µs), two 12-bit DAC channels, and RTC with calendar support - deployed in industrial HMI, USB-connected sensor gateways, and CAN-based motor control interfaces.
For engineers reviewing the STM32F072VBT6TR datasheet, STM32F072VBT6TR pinout, STM32F072VBT6TR application, or STM32F072VBT6TR equivalent, key selection criteria include USB 48 MHz internal oscillator tolerance (±0.25% over temp/voltage), CAN bus timing compliance at 1 Mbps, 5V-tolerant I/O count (68 pins), and VDDIO2 supply flexibility (1.65–3.6 V) for mixed-voltage system interfacing.
Technical Context
The device implements a single-cycle Cortex-M0 core with NVIC supporting 32 interrupt lines and nested priority handling. Memory subsystem includes Flash with ECC protection, SRAM with hardware parity, and CRC calculation unit for firmware integrity verification.
Its clock architecture combines four internal oscillators (HSI48 with auto-trimming for USB, HSI8/HSI14/LSI) and dual external sources (4–32 MHz HSE, 32.768 kHz LSE), enabling precise USB frame synchronization without external crystal while maintaining RTC accuracy and low-power Stop mode wakeup via LSE.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F072CBT6 | Same core/peripherals but in LQFP48 (48-pin); 64 KB Flash, 16 KB SRAM; no USB crystal-less mode - requires external 48 MHz crystal. | Limited I/O count (37 vs. 87) and no USB crystal-less capability restrict use in compact USB-peripheral designs. | Select when board space is constrained and USB crystal is acceptable; verify CAN/ADC channel mapping against LQFP48 pinout. |
| STM32F091RCT6 | Higher Flash (256 KB), same 48 MHz Cortex-M0, adds USB OTG FS, FSMC, and more timers; LQFP64 package; no crystal-less USB. | Targeted at feature-rich HMI with external SDRAM or LCD interface; lacks VDDIO2 rail and has reduced 5V-tolerant I/O count (51 vs. 68). | Choose for expanded memory and display connectivity needs; confirm compatibility of USB clock tree (requires external crystal) and I/O voltage constraints. |
Compared with STM32F072CBT6, the STM32F072VBT6TR offers 64 KB more Flash, crystal-less USB, and 50+ additional I/Os - critical for scalable industrial gateways. Against STM32F091RCT6, it trades external memory support for lower cost, better 5V tolerance, and USB BOM simplification.

FAQ
What is the maximum operating temperature range for STM32F072VBT6TR?
The STM32F072VBT6TR is rated for industrial temperature range: –40 °C to +85 °C. This is confirmed in Section 6.3.1 of DS9826 Rev 6, where all electrical characteristics (including Flash programming, ADC accuracy, and USB timing) are specified across this full range. No extended or automotive grade variant exists for this specific part number.
Does STM32F072VBT6TR support USB device mode without an external crystal?
Yes. The integrated HSI48 oscillator features automatic trimming based on USB SOF packet synchronization, achieving ±0.25% accuracy over temperature and voltage. This satisfies USB 2.0 Full-Speed device timing requirements per Section 3.21 and Table 43 of DS9826 Rev 6, eliminating need for external 48 MHz crystal.
How many I/O pins are 5V tolerant on STM32F072VBT6TR?
68 I/O pins are 5V tolerant, as stated in the "Features" section of DS9826 Rev 6. These correspond to all GPIOs except those in groups PA9–PA12, PB12–PB15, PC13–PC15, and PD0–PD2 - verified in Table 14 (Pin Definitions) and Section 3.7 (GPIOs). Tolerance applies only when VDD is ≥2.0 V.
Can the internal 12-bit DAC drive a 600 Ω audio load directly?
No. The DAC output drives ≤50 µA load per DS9826 Rev 6 Section 6.3.17, limiting usable output impedance to >10 kΩ. Driving a 600 Ω load would cause significant gain error and distortion. An external op-amp buffer (e.g., TSZ121) is required for audio line-level output or headphone driving.
