Product details
Overview
STM32F072C8T7 from STMicroelectronics is a 32-bit Arm® Cortex®-M0 microcontroller with 64 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 sensor nodes, USB-connected HMI modules, and CAN-based building automation controllers.
For engineers reviewing the STM32F072C8T7 datasheet, STM32F072C8T7 pinout, STM32F072C8T7 application, or STM32F072C8T7 equivalent, key selection criteria include USB clocking autonomy (48 MHz internal oscillator with BCD/LPM), 5V-tolerant I/O count (up to 68 pins), CAN+USB dual-interface coexistence, and VDDIO2 support for mixed-voltage peripheral interfacing.
Technical Context
The STM32F072C8T7 integrates a single-cycle Cortex-M0 core running at up to 48 MHz, supported by an internal 48 MHz oscillator with automatic trimming via USB SOF synchronization - eliminating external crystal requirements for USB operation. Its memory subsystem includes 64 KB of Flash with error correction and 16 KB of HW-parity SRAM, enabling robust firmware execution in safety-aware applications.
Clock architecture combines multiple sources: 4–32 MHz HSE, 32 kHz LSE for RTC, 8 MHz HSI with x6 PLL, 40 kHz LSI, and the critical 48 MHz HSI48 tuned for USB timing compliance. Power management supports Sleep/Stop/Standby modes with VBAT backup for RTC and registers, and programmable voltage detector (PVD) for brown-out monitoring.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | Arm Cortex-M0, 48 MHz max - enables real-time control loop execution within 20.8 ns instruction cycle time. |
| Flash / SRAM | 64 KB Flash with ECC, 16 KB SRAM with hardware parity - supports IEC 61508 SIL-2 functional safety requirements. |
| USB Interface | Crystal-less USB 2.0 Full-Speed with BCD and LPM - eliminates 12 MHz crystal, reduces BOM cost and PCB area. |
| CAN Interface | CAN 2.0B controller with dedicated TX/RX pins and FIFO buffering - supports automotive body electronics and industrial fieldbus nodes. |
| Analog Peripherals | 12-bit ADC (16 ch, 1 µs), dual 12-bit DAC, 2 analog comparators - enables closed-loop analog signal conditioning without external ICs. |
| I/O Capability | 39 GPIOs (LQFP48 package), up to 68 with 5V tolerance, 19 with independent VDDIO2 supply - simplifies level-shifting for mixed-voltage sensors and logic. |
| Supply Range | VDD = 2.0–3.6 V; VDDA = VDD to 3.6 V; VDDIO2 = 1.65–3.6 V - supports flexible power domain partitioning in multi-rail systems. |
Pinout & Package
LQFP48 (7 × 7 mm, 0.5 mm pitch), RoHS-compliant ECOPACK®2 package with exposed thermal pad - optimized for compact industrial control boards and USB-C peripheral designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VSS, VSSA | Power and ground rails | Dual-supply separation ensures analog accuracy; VDDA must be ≥ VDD for ADC/DAC reference stability. |
| PA11/PA12 | USB DM/DP | Dedicated full-speed USB pins with internal transceivers - require no external PHY or termination resistors. |
| PA11/PA12 (alt) | CAN RX/TX | Shared alternate function allows CAN and USB on same pins only in non-simultaneous mode - requires software reconfiguration. |
| PA0–PA15, PB0–PB15, PC13–PC15 | General-purpose I/O | 39 total GPIOs in LQFP48; PC13–PC15 reserved for RTC oscillator and tamper - not usable as general I/O when RTC active. |
| NRST | Active-low reset input | Internal pull-up; accepts 1.65–5.5 V logic - compatible with 3.3 V and 5 V reset supervisors. |
| BOOT0 | Boot mode selection | Pulled low internally; external pull-up required for system memory boot - enables field firmware recovery via USART. |
Key Features
| Feature | Design Value |
|---|---|

| Integrated CAN 2.0B | Hardware message filtering, 14 receive FIFOs, and automatic retransmission - reduces CPU load in bus arbitration-heavy networks. |
| Capacitive Sensing Controller (TSC) | 24-channel touch sensing with built-in charge transfer and noise immunity - enables direct integration of touchkeys/rotary controls without external ICs. |
| Low-power RTC with VBAT | Calendar RTC + alarm + periodic wakeup from Stop/Standby - maintains timekeeping during main power loss using coin-cell battery. |
| Programmable Voltage Detector (PVD) | 7-level threshold selection (2.0–2.9 V) with interrupt generation - provides early warning of supply droop before brown-out reset triggers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F070F6P6 | No CAN, no USB, 32 KB Flash, no HSI48 oscillator | Cost-sensitive, non-USB/non-CAN control tasks only | Select only if USB/CAN functionality is excluded and BOM cost is primary constraint. |

FAQ
Does STM32F072C8T7 support USB device mode without an external crystal?
Yes. It features an internal 48 MHz HSI48 oscillator with automatic trimming based on USB Start-of-Frame (SOF) packets, achieving ±0.25% accuracy across temperature and voltage - fully compliant with USB 2.0 Full-Speed device specifications without external crystal or PLL.
What is the maximum number of 5V-tolerant I/Os on the LQFP48 package?
The STM32F072C8T7 in LQFP48 provides 39 GPIOs total, of which 37 are 5V-tolerant (all except PA13, PA14, and BOOT0). This enables direct interfacing with legacy 5V logic, sensors, and displays without level shifters.
Can CAN and USB operate simultaneously on STM32F072C8T7?
No. PA11 and PA12 serve dual roles as USB DP/DM and CAN RX/TX, but cannot function concurrently. Simultaneous CAN+USB operation requires external multiplexing or use of the STM32F072RBT6 (LQFP64) with dedicated pins for both interfaces.
Is the internal 12-bit DAC monotonic across its full range?
Yes. The dual-channel 12-bit DAC meets monotonicity specification per datasheet Table 60: INL ≤ ±1 LSB and DNL ≤ ±0.5 LSB across 0–VREF+, ensuring predictable analog output behavior in closed-loop control and waveform generation applications.
