Product details
Overview
STM32F072V8T6 from STMicroelectronics is an Arm® Cortex®-M0 32-bit microcontroller operating at up to 48 MHz, featuring 64 KB Flash, 16 KB SRAM with hardware parity, crystal-less USB 2.0 Full-Speed interface, CAN 2.0B controller, and integrated 12-bit ADC/DAC. It targets embedded control applications requiring robust connectivity, low-power operation, and analog signal processing - such as industrial sensor nodes and USB-connected human interface devices.
For engineers reviewing the STM32F072V8T6 datasheet, STM32F072V8T6 pinout, STM32F072V8T6 application, or STM32F072V8T6 equivalent, key selection criteria include its internal 48 MHz oscillator with USB BCD/LPM support, 5V-tolerant I/Os (up to 68 pins), RTC with calendar and alarm, and dual 12-bit DAC channels for precise analog output generation.
Technical Context
The STM32F072V8T6 integrates a single-cycle Cortex-M0 core with NVIC, SysTick, and advanced interrupt/event routing. Its clock system combines internal oscillators (HSI48 with automatic trimming for USB, HSI8, LSI, LSE) and external sources (4–32 MHz HSE, 32.768 kHz RTC crystal), enabling precise timing without external crystals in USB applications.
Peripheral integration includes a 7-channel DMA controller, two I²C interfaces (one with SMBus/PMBus), four USARTs (two with ISO7816/LIN/IrDA), two SPI/I²S modules, one CAN 2.0B controller, and HDMI CEC wakeup - all mapped to up to 87 GPIOs with configurable alternate functions and independent VDDIO2 supply for 19 pins.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | Arm Cortex-M0, 48 MHz max - enables real-time deterministic control with <20 ns instruction cycle time at full speed. |
| Memory | 64 KB Flash + 16 KB SRAM with HW parity - supports secure firmware storage and error-detecting data buffers for safety-critical tasks. |
| USB Interface | Crystal-less USB 2.0 FS with BCD & LPM - eliminates external 48 MHz crystal, reducing BOM cost and PCB area while supporting battery-powered suspend/resume. |
| Analog Peripherals | 1×12-bit ADC (16 ch, 1 µs), 2×12-bit DAC, 2×comparators - enables closed-loop analog sensing/actuation (e.g., motor current feedback + voltage reference generation). |
| Timers | 12 timers including TIM1 (6-ch PWM), TIM2/3/14–17, TIM6/7 - supports multi-phase motor control, IR decoding, and precise PWM-based LED dimming or DAC triggering. |
| I/O Capability | Up to 87 GPIOs; 68 with 5V tolerance, 19 with VDDIO2 (1.65–3.6 V) - allows direct interfacing with legacy 5V logic and mixed-voltage subsystems without level shifters. |
| Low-Power Modes | Sleep, Stop, Standby with RTC/VBAT backup - achieves sub-1 µA standby current with RTC running, suitable for battery-backed metering or alarm systems. |
Pinout & Package
LQFP64 package (10 × 10 mm, 0.5 mm pitch), RoHS-compliant ECOPACK®2, with 64 leads and exposed thermal pad. Pinout validated per STMicroelectronics DS9826 Rev 6, Section 5 (Pinouts and pin descriptions).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VSS, VSSA | Power supply rails | Digital (2.0–3.6 V), analog (2.4–3.6 V), and ground domains - require separate decoupling for noise-sensitive ADC/DAC operation. |
| PA0–PA15, PB0–PB15, PC13–PC15, PD0–PD2 | General-purpose I/O | 87 total GPIOs; PA13/PA14 = SWDIO/SWCLK debug; PC13 = RTC tamper/wakeup; PD0/PD1 = OSC_IN/OSC_OUT. |
| PA11/PA12 | USB D+/D− | Dedicated full-speed USB transceiver pins - internally pulled up/down; require 1.5 kΩ pull-up on D+ for device enumeration. |
| PA9/PA10 | USART1 TX/RX | Default UART interface for bootloader or debug console - supports auto baud rate detection and wake-up from low-power modes. |
| PB8/PB9 | I²C1 SCL/SDA | Fast Mode Plus (1 Mbit/s) with 20 mA sink - drives standard I²C buses and SMBus-compatible sensors without external pull-ups in high-noise environments. |
| PA15/PB3/PB4 | JTAG/SWD debug | SWD-only mode enabled by default; JTAG disabled to free PB3/PB4 for GPIO use unless reconfigured via option bytes. |
Key Features
| Feature | Design Value |
|---|---|
| Crystal-less USB 2.0 FS | Internal 48 MHz HSI48 oscillator trimmed via USB SOF packets - removes need for external crystal, simplifying layout and lowering cost in USB peripheral designs. |
| Capacitive Touch Sensing | 24-channel TSC supporting touchkey, linear, and rotary sensors - enables intuitive HMI without external ICs, using only GPIOs and firmware library. |
| Programmable Voltage Detector | Configurable threshold (2.0–2.9 V) with interrupt/wakeup - provides early brown-out warning before system reset, allowing graceful state save in flash or RAM. |
| Independent VDDIO2 Supply | 19 GPIOs powered separately (1.65–3.6 V) - permits safe interfacing with 1.8 V or 2.5 V peripherals while main I/Os run at 3.3 V. |
| Hardware CRC Unit | 32-bit polynomial engine (CRC-32, CRC-16, CRC-CCITT) - accelerates firmware integrity checks and communication frame validation without CPU overhead. |

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) package with 128 KB Flash and identical 64 KB SRAM | Reduced I/O count (51 vs. 64 usable pins); no VDDIO2 support; fewer USB/CAN-capable pins | Select when board space is constrained and full I/O count or VDDIO2 is unnecessary. |
| STM32F070F6P6 | Lower-cost variant: 32 KB Flash, no CAN, no USB, no DAC, 16 KB SRAM, LQFP48 | Lacks USB and CAN interfaces; limited analog capability; targets cost-sensitive non-USB applications | Choose only if USB/CAN are excluded from design and BOM cost reduction outweighs feature loss. |
Compared with STM32F072CBT6, the STM32F072V8T6 offers higher I/O density and VDDIO2 flexibility in LQFP64; versus STM32F070F6P6, it delivers full USB/CAN connectivity and dual DACs essential for mixed-signal edge devices - making it the optimal choice for USB-enabled industrial controllers requiring analog precision and fieldbus interoperability.

FAQ
Does STM32F072V8T6 support USB device mode without an external crystal?
Yes. The STM32F072V8T6 integrates an internal 48 MHz HSI48 oscillator with automatic trimming based on USB Start-of-Frame (SOF) synchronization, enabling full-speed USB 2.0 device operation without an external crystal - verified in ST's AN4879 application note and DS9826 Section 3.6.
What is the maximum number of 5V-tolerant I/Os on this device?
The STM32F072V8T6 supports up to 68 5V-tolerant I/Os across its GPIO ports (PA, PB, PC, PD). This is confirmed in the "Features" section of DS9826 Rev 6, page 1, and validated in electrical characteristics Table 53 (I/O static characteristics) on page 78.
Can the internal 12-bit DAC generate synchronized waveforms?
Yes. Both DAC channels (DAC1 and DAC2) support hardware trigger modes via TIM2, TIM3, TIM6, or TIM7 - enabling precise, jitter-free waveform generation (e.g., triangle/sine) synchronized to timer events, as documented in Section 3.11 and Table 60 of DS9826 Rev 6.
Is the RTC calendar function battery-backed when VDD is removed?
Yes. The RTC and 42-byte backup registers retain functionality during VDD loss using the VBAT pin (2.0–3.6 V), supported by an external coin cell or supercapacitor - detailed in Section 3.15 and electrical specs Table 63 (VBAT monitoring characteristics) on page 92 of DS9826 Rev 6.
