Product details
Overview
STM32F072V8H6 from STMicroelectronics is an Arm® Cortex®-M0 32-bit microcontroller with 64 KB Flash, 16 KB SRAM, crystal-less USB 2.0 Full-Speed interface, CAN 2.0B controller, and integrated 12-bit ADC/DAC-designed for industrial control, smart sensors, and USB-connected embedded devices operating at 2.0–3.6 V.
For engineers reviewing the STM32F072V8H6 datasheet, STM32F072V8H6 pinout, STM32F072V8H6 application, or STM32F072V8H6 equivalent, key selection criteria include USB clocking autonomy (48 MHz internal oscillator with trimming), 5V-tolerant I/O count (up to 68 pins), CAN+USB coexistence in a single chip, and RTC with calibration and wakeup from Stop/Standby modes.
Technical Context
The STM32F072V8H6 integrates a 48 MHz Arm Cortex-M0 core with hardware CRC, memory protection unit (MPU), and nested vectored interrupt controller (NVIC). It supports dual-clock domains: high-speed (HSE/HSI48/PLL) for USB and CPU, and low-speed (LSE/LSI) for RTC and watchdogs.
Its peripheral set includes one 12-bit ADC (16-channel, 1 µs conversion), two 12-bit DAC channels, seven 16-bit timers plus one 32-bit timer and one advanced-control timer (TIM1) with six PWM outputs, and full-duplex communication stacks: 4× USART (2 with ISO7816/LIN/IrDA), 2× I²C (Fast Mode Plus), 2× SPI/I²S, CAN 2.0B, and USB 2.0 FS with BCD and LPM support.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M0, up to 48 MHz - enables real-time deterministic control with Thumb-2 instruction set and <100 ns interrupt latency. |
| Memory | 64 KB Flash + 16 KB SRAM with HW parity - supports firmware updates in-field and data integrity for safety-critical variables. |
| USB Interface | Crystal-less USB 2.0 Full-Speed - eliminates external 48 MHz crystal, reducing BOM cost and PCB area while maintaining ±0.25% frequency accuracy via internal HSI48 auto-trimming. |
| CAN Interface | CAN 2.0B controller - provides robust automotive-grade serial bus communication with message filtering, FIFO buffering, and automatic retransmission. |
| Analog Peripherals | 12-bit ADC (16 ch, 1 µs), 2× 12-bit DAC, 2× analog comparators - enables closed-loop analog sensing, waveform generation, and threshold detection without external components. |
| I/O Capability | Up to 87 fast I/Os, 68 with 5V tolerance - allows direct interfacing with legacy 5V logic and industrial sensors without level shifters. |
| Power Management | Three low-power modes (Sleep/Stop/Standby), programmable voltage detector (PVD), VBAT backup supply - supports battery-backed RTC and ultra-low-power wake-on-event operation down to 0.3 µA in Standby. |
Pinout & Package
STM32F072V8H6 uses a 100-pin LQFP package (14 × 14 mm, 0.5 mm pitch) with ECOPACK®2 RoHS-compliant finish. Pin functions are defined per STM32F072x8/xB datasheet Section 5 (Pinouts and pin descriptions), including dedicated USB D+/D−, CAN RX/TX, and multiple alternate-function remappable GPIOs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD/VSS | Digital power/ground | Primary 2.0–3.6 V supply domain for core and digital peripherals; requires local decoupling per datasheet layout guidelines. |
| VDDA/VSSA | Analog power/ground | Independent 2.4–3.6 V analog supply for ADC/DAC/comp/RTC; must be filtered and separated from digital ground to maintain SNR > 70 dB. |
| PA11/PA12 | USB D+/D− | Dedicated full-speed USB transceiver pins; require 1.5 kΩ pull-up on D+ for device enumeration; no external PHY needed. |
| PB8/PB9 | CAN RX/TX | Direct connection to external CAN transceiver; support dominant/recessive bit timing compliant with ISO 11898-1. |
| PC13/PC14/PC15 | RTC oscillator inputs | Support 32.768 kHz crystal for calendar RTC; PC14/PC15 have built-in load capacitors (12.5 pF) to reduce external component count. |
| NRST | Active-low reset | Asynchronous reset input with Schmitt trigger; accepts 1–10 µs pulse width; internal pull-up ensures reliable boot without external resistor. |
Key Features
| Feature | Design Value |
|---|---|
| Crystal-less USB 2.0 FS | Internal 48 MHz HSI48 oscillator with automatic trimming against USB SOF packet - eliminates crystal, saves ~$0.15 BOM cost and 2 mm² PCB area. |
| Capacitive Touch Sensing | 24-channel TSC supporting touchkey, linear, and rotary sensors - enables button/slider/knob UI without external ICs or firmware-intensive polling. |
| Advanced-Control Timer (TIM1) | 6-channel complementary PWM with dead-time insertion and fault protection - suitable for 3-phase motor control and digital power supply gate driving. |
| USB Battery Charging Detection (BCD) | Integrated USB BC 1.2 detection logic - identifies SDP/CDP/DCP ports and configures current limits (500 mA/1.5 A/Max) autonomously. |
| HDMI CEC Wakeup | Hardware CEC receiver with header-detection wakeup - allows low-power standby mode while monitoring HDMI remote commands without MCU active. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F072CBT6 | LQFP48 package (48-pin), 128 KB Flash, same peripherals - smaller footprint but fewer I/Os (37 vs. 87) and no CAN routing on available pins. | Suitable for space-constrained USB-only designs without CAN requirement; lacks PB8/PB9 routing for CAN transceiver. | Select when board area is critical and CAN is not required; verify USB and ADC channel availability in 48-pin mapping. |
| STM32F042K6T6 | LQFP32 package, 32 KB Flash, USB FS only (no CAN), 1× 12-bit ADC (10 ch), no DAC - lower cost but reduced integration. | Targeted at basic USB HID devices (keyboards, mice) or simple sensor nodes where CAN and dual DAC are unnecessary. | Choose for cost-sensitive, USB-centric applications with minimal analog needs; not drop-in compatible due to missing CAN and reduced memory/I/O. |
Compared with STM32F072CBT6 and STM32F042K6T6, the STM32F072V8H6 uniquely delivers CAN+USB coexistence in LQFP100 with full peripheral complement - making it the only option among the three for industrial USB-CAN gateways requiring ≥68 5V-tolerant I/Os and RTC+VBAT support.

FAQ
Does STM32F072V8H6 support USB device mode without an external crystal?
Yes. The device integrates an internal 48 MHz HSI48 oscillator with automatic trimming synchronized to USB Start-of-Frame (SOF) packets, achieving ±0.25% accuracy required for USB Full-Speed device operation - eliminating need for external 48 MHz crystal or oscillator.
What is the maximum number of 5V-tolerant I/Os on STM32F072V8H6?
The STM32F072V8H6 supports up to 68 5V-tolerant I/Os across its 100-pin LQFP package. These pins are explicitly marked in the datasheet's "Pin Definitions" table (Section 5) and include all GPIOs except those assigned to analog inputs (VREF+, VREF−), USB D+/D−, and BOOT0.
Can the internal RTC run from VBAT while the main supply is off?
Yes. The STM32F072V8H6 includes dedicated VBAT pin powering the RTC oscillator, calendar counters, and 32 backup registers. When VDD is removed, the RTC continues timekeeping and can generate alarms or periodic wakeups from Stop/Standby modes using the 32.768 kHz LSE or LSI clock source.
Is there hardware support for USB Battery Charging (BC) 1.2 detection?
Yes. The USB peripheral includes integrated Battery Charging Detection (BCD) logic compliant with USB BC 1.2 specification. It automatically detects SDP (Standard Downstream Port), CDP (Charging Downstream Port), and DCP (Dedicated Charging Port) and configures appropriate current limits (500 mA, 1.5 A, or max) without firmware intervention.
