Product details
Overview
STM32F072VBH6 from STMicroelectronics is an Arm® Cortex®-M0 32-bit MCU with 128 KB Flash, 16 KB SRAM, crystal-less USB 2.0 FS interface, CAN 2.0B controller, and integrated 12-bit ADC/DAC - deployed in industrial HMI, USB-connected sensor gateways, and CAN-based building automation controllers.
For engineers reviewing the STM32F072VBH6 datasheet, STM32F072VBH6 pinout, STM32F072VBH6 application, or STM32F072VBH6 equivalent, key selection criteria include USB clocking autonomy (48 MHz internal oscillator with trimming), 5V-tolerant I/O count (68 pins), CAN+USB coexistence capability, and RTC with VBAT-backed alarm/wakeup in Stop mode.
Technical Context
The device integrates a single-cycle Cortex-M0 core running at up to 48 MHz, supported by a multi-source clock system: 4–32 MHz external crystal, 32 kHz LSE for RTC, and a factory-trimmed 48 MHz HSI48 oscillator enabling full-speed USB without external crystal. Its power architecture includes independent VDDA (2.4–3.6 V) and VDDIO2 (1.65–3.6 V) rails for analog and selective I/O domains.
Peripheral integration centers on real-time control and connectivity: one advanced-control timer (TIM1) delivering six-channel PWM, two I²C interfaces (one Fast Mode Plus), four USARTs (two with ISO7816/LIN/IrDA), dual SPI/I²S, CAN 2.0B, and a crystal-less USB 2.0 FS PHY with BCD and LPM support - all accessible via 87 GPIOs, 68 of which are 5V tolerant.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | Arm Cortex-M0, 48 MHz max - enables deterministic real-time control with <100 ns interrupt latency |
| Memory | 128 KB Flash + 16 KB SRAM with HW parity - supports secure firmware updates and robust data logging |
| USB Interface | Crystal-less USB 2.0 Full-Speed - eliminates external 48 MHz crystal, reducing BOM cost and PCB area |
| CAN Interface | CAN 2.0B controller - enables direct connection to automotive or industrial fieldbus networks without transceiver logic |
| ADC | 12-bit, 1.0 µs SAR ADC (16 channels, 0–3.6 V range) - supports fast sampling of analog sensors with separate VDDA supply |
| DAC | 12-bit dual-channel DAC - provides precise analog output for calibration signals or actuator control |
| I/O Count | 87 GPIOs, 68 5V-tolerant - simplifies interfacing with legacy 5V peripherals and industrial logic levels |
| Supply Range | VDD = 2.0–3.6 V, VDDA = VDD–3.6 V - allows single-rail design while maintaining analog accuracy |
Pinout & Package
STM32F072VBH6 uses a UFBGA100 (7 × 7 mm, 0.5 mm pitch) package with 100 terminals. Pin functions are defined across five GPIO ports (A–E) plus dedicated peripheral pins for USB, CAN, RTC, and reset. All I/Os support remappable alternate functions via AFR registers.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VSS | Digital power/ground | Primary 2.0–3.6 V supply domain; decoupling required per STM32 layout guidelines |
| VDDA, VSSA | Analog power/ground | Isolated 2.4–3.6 V rail for ADC/DAC/comp/RTC - must be filtered and separated from digital ground |
| PA11/PA12 | USB DM/DP | Dedicated full-speed USB differential pair; internal pull-ups enabled in device mode |
| PB8/PB9 | CAN RX/TX | Direct connection to external CAN transceiver; supports loopback and silent modes |
| PC13/PC14/PC15 | RTC_OUT/OSC32_IN/OSC32_OUT | Supports 32.768 kHz crystal or external clock for calendar RTC with calibration |
| NRST | Active-low reset | Asynchronous reset input with internal pull-up; accepts 1.65–3.6 V logic levels |
| BOOT0 | Boot mode select | High at power-on selects system memory bootloader; requires external pull-down for main Flash execution |
Key Features
| Feature | Design Value |
|---|---|
| HSI48 oscillator with auto-trimming | Enables crystal-less USB operation with ±0.25% frequency stability over temperature/voltage |
| Capacitive sensing controller (TSC) | 24-channel touch-sensing engine supporting touchkey, linear, and rotary sliders without external components |
| Programmable voltage detector (PVD) | Monitors VDD in 8 user-selectable thresholds (2.0–2.9 V) to trigger interrupts before brownout |
| Low-power modes (Stop/Standby) | Retains SRAM and register state in Stop mode (2.3 µA typical); RTC + backup registers active in Standby (0.8 µA) |
| Serial wire debug (SWD) | 2-pin debug interface supporting full run-control, breakpoints, and memory access - no JTAG overhead |
| 96-bit unique ID | Factory-programmed serial number used for secure device authentication and license binding |

FAQ
Does STM32F072VBH6 require an external crystal for USB operation?
No. The device integrates a factory-trimmed 48 MHz HSI48 oscillator with automatic synchronization to USB SOF packets, enabling full-speed USB 2.0 operation without any external crystal - verified per DS9826 Rev 6 Section 3.6 and Table 43.
What is the maximum operating temperature range for STM32F072VBH6?
The STM32F072VBH6 is rated for industrial temperature range: –40 °C to +85 °C ambient, as specified in Section 6.3.1 of DS9826 Rev 6. It meets JEDEC J-STD-020 moisture sensitivity level MSL3 and supports reflow soldering per standard profile.
How many I/O pins support 5V tolerance, and are they configurable per pin?
68 GPIOs are 5V tolerant (as listed in Section 3.7 and Table 14 of DS9826), including all pins except those assigned to USB, RTC, and analog inputs. Tolerance is hardware-defined per pin group (PA–PE) and cannot be disabled or reconfigured in software.
Can the internal 12-bit DAC drive a 1 kΩ load with full-scale accuracy?
Yes - the DAC output maintains 12-bit monotonicity and ±1 LSB INL up to 1 mA load (equivalent to ≥3.3 kΩ at 3.3 V), per Table 60. Driving 1 kΩ causes ~1.5% gain error due to output impedance (~15 kΩ typical), requiring external buffer for precision applications.
