Product details
Overview
STM32F072VBH6TR from STMicroelectronics is a 32-bit Arm® Cortex®-M0 microcontroller in UFBGA100 package, operating up to 48 MHz with 128 KB Flash and 16 KB SRAM. It integrates crystal-less USB 2.0 Full-Speed, CAN 2.0B, dual 12-bit ADC (16-channel, 1.0 µs), dual-channel 12-bit DAC, and RTC with calendar and alarm-used in industrial HMI panels requiring embedded USB device connectivity, CAN bus diagnostics, and analog sensor interfacing.
For engineers reviewing the STM32F072VBH6TR datasheet, STM32F072VBH6TR pinout, STM32F072VBH6TR application, or STM32F072VBH6TR equivalent, key selection criteria include USB 2.0 FS timing autonomy (48 MHz internal oscillator with BCD/LPM), CAN interface compliance, 5V-tolerant I/O count (68 pins), VDDIO2 independent supply support, and capacitive touch sensing capability (24 channels).
Technical Context
The STM32F072VBH6TR implements a single-core Arm Cortex-M0 CPU with Harvard architecture, supporting Thumb-2 instruction set and NVIC with 32 interrupt lines. Its clock system includes four internal oscillators (HSI8, HSI14, HSI48, LSI) plus external 4–32 MHz HSE and 32.768 kHz LSE, with automatic HSI48 trimming via USB SOF synchronization for crystal-less USB operation.
Peripheral integration centers on real-time control and mixed-signal interfacing: one advanced-control timer (TIM1) for 6-channel PWM, seven general-purpose timers (including 32-bit TIM2), two I²C interfaces with Fast Mode Plus (1 Mbit/s), four USARTs (two with ISO7816/LIN/IrDA), two SPI/I²S, CAN 2.0B controller, and HDMI CEC wakeup capability.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F072CBT6 | LQFP48 package (48-pin), 64 KB Flash, same peripherals - lacks 19× VDDIO2 I/Os and 24-channel TSC | Suitable for space-constrained but lower-feature designs (e.g., basic USB-CDC dongles without touch or CAN) | Select when board layout requires QFP and analog/touch requirements are minimal |
| STM32F070CBT6 | No USB PHY, no CAN, no DAC, 36 KB Flash - retains 12-bit ADC and 68× 5V-tolerant I/Os | Targeted at cost-sensitive industrial I/O expanders or simple sensor nodes without USB/CAN | Choose only if USB and CAN are excluded from system architecture |
Compared with STM32F072CBT6, the VBH6TR adds 64 KB Flash, VDDIO2 flexibility, and full TSC-critical for HMI-rich designs; versus STM32F070CBT6, it delivers essential USB/CAN connectivity and dual DACs required for diagnostic and control functions.

FAQ
Does STM32F072VBH6TR support crystal-less USB operation?
Yes. It integrates an internal 48 MHz HSI48 oscillator with automatic trimming using USB Start-of-Frame (SOF) packets, enabling full-speed USB 2.0 device operation without an external crystal. This is confirmed in Section 3.6 and Table 43 of DS9826 Rev 6, with ±0.25% frequency accuracy under typical conditions.
What is the maximum number of 5V-tolerant I/Os on this device?
The STM32F072VBH6TR supports up to 68 I/Os with 5V tolerance, as specified in the "Features" section of DS9826 Rev 6. These are distributed across GPIO ports A–F and include all pins except those dedicated to analog functions (VREF+, VREF−, VBAT, etc.) and specific alternate functions like USB D+/D−.
Can the internal DAC drive standard audio line-level signals?
No. The dual 12-bit DAC outputs are rail-to-rail but lack built-in amplification or current drive capability for line-level audio (typically ±1 V or 2 Vpp into 10 kΩ). They require external op-amp buffering and level-shifting, as documented in Section 3.11 and Table 60 of DS9826 Rev 6, where output load is specified at ≤100 µA.
Is the CAN interface compatible with ISO 11898-2 high-speed CAN physical layer?
No. The integrated CAN controller supports ISO 11898-1 (data link layer) only. Physical layer compliance requires an external high-speed CAN transceiver (e.g., SN65HVD230) connected to PB8 (CAN_RX) and PB9 (CAN_TX), as shown in Figure 132 of DS9826 Rev 6 and confirmed in Section 3.20.
