Product details
Overview
STM32F072C8T6TR from STMicroelectronics is a 32-bit Arm® Cortex®-M0 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. It operates from 2.0–3.6 V, supports up to 48 MHz CPU frequency, and targets embedded control applications requiring mixed-signal integration and robust communication in space-constrained industrial and consumer designs.
For engineers reviewing the STM32F072C8T6TR datasheet, STM32F072C8T6TR pinout, STM32F072C8T6TR application, or STM32F072C8T6TR equivalent, key selection considerations include USB FS timing autonomy (48 MHz internal oscillator), CAN+USB coexistence capability, 5V-tolerant I/O count (68 pins), and capacitive touch sensing support for HMI interfaces.
Technical Context
This MCU integrates a single-cycle Cortex-M0 core with tightly coupled peripherals including dual DMA channels, nested vectored interrupt controller (NVIC), and clock recovery system (CRS) enabling precise USB frame synchronization without external crystal. Its power architecture includes independent VDDA (2.4–3.6 V) and VDDIO2 (1.65–3.6 V) rails for analog integrity and flexible I/O voltage domains.
The peripheral set is optimized for real-time control: one advanced-control timer (TIM1) delivers six-channel PWM with dead-time insertion; two 12-bit converters (ADC + dual-channel DAC) enable closed-loop analog signal generation and acquisition; and the USB-CAN combo supports automotive diagnostics and industrial gateway functions within a single chip.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M0, 48 MHz max - enables deterministic real-time execution with <100 ns interrupt latency. |
| Memory | 64 KB Flash / 16 KB SRAM with HW parity - supports secure firmware storage and runtime data integrity checking. |
| USB Interface | Crystal-less USB 2.0 FS - eliminates external 48 MHz crystal, reducing BOM cost and PCB area. |
| CAN Interface | CAN 2.0B controller - provides robust automotive-grade serial bus communication with message filtering and FIFO buffering. |
| Analog Peripherals | 12-bit ADC (16 ch, 1 µs), dual 12-bit DAC - enables simultaneous sensor acquisition and analog output control in motor or power supply feedback loops. |
| I/O Capability | Up to 68 5V-tolerant GPIOs - allows direct interfacing with legacy 5V logic without level shifters. |
| Low-Power Modes | Sleep/Stop/Standby with RTC & backup registers - achieves sub-1 µA standby current for battery-backed applications. |
Pinout & Package
STM32F072C8T6TR is housed in a 48-pin UFQFPN (7 × 7 mm, 0.5 mm pitch) package compliant with ECOPACK®2 environmental standards. This compact, lead-free, thermally enhanced package supports reflow soldering and is suitable for high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VSS, VSSA | Power and ground rails | Separate digital/analog supplies ensure noise isolation; VDDA must be ≥2.4 V for full ADC/DAC accuracy. |
| PA11/PA12 | USB DM/DP | Dedicated full-speed USB transceiver pins with internal pull-ups; require no external crystal due to HSI48 + CRS calibration. |
| PB8/PB9 | CAN RX/TX | Direct connection to external CAN transceiver; support loopback mode for self-test without physical bus. |
| PA0–PA7, PB0–PB15, PC13–PC15 | General-purpose I/O | 68 pins are 5V-tolerant; PC13–PC15 reserved for LSE/RTC functions and support tamper detection. |
| PA4–PA5 | ADC1_IN4/ADC1_IN5 | Analog input channels mapped to internal temperature sensor and VREFINT for system monitoring. |
Key Features
| Feature | Design Value |
|---|---|
| Crystal-less USB | HSI48 oscillator trimmed via USB SOF packets - eliminates crystal, saves ~$0.15 BOM cost and 2 mm² board area. |
| Capacitive Touch Sensing | 24-channel TSC with built-in charge transfer - enables button/slider/rotary controls without external ICs or firmware overhead. |
| Independent Analog Supply | VDDA rail (2.4–3.6 V) decoupled from VDD - maintains ADC/DAC linearity and SNR even during digital switching noise. |
| Programmable Voltage Detector | PVD with 4-level threshold selection - triggers interrupt or reset on brown-out, supporting fail-safe shutdown in power-critical systems. |
| Advanced-Control Timer | TIM1 with complementary PWM outputs and programmable dead-time - directly drives half-bridge MOSFETs in motor or SMPS applications. |

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 crystal-less USB oscillator | Limited to basic control without bus connectivity or host interface | Select when CAN/USB are unnecessary and cost is primary constraint |
| STM32F072CBT6 | Same die, LQFP48 package (same pinout), identical specs | Identical functionality; differs only in package mechanicals and thermal performance | Choose for easier hand-soldering or legacy footprint compatibility |
Compared with STM32F072C8T6TR, the F070F6P6 lacks essential CAN/USB for diagnostic tools, while the F072CBT6 offers identical electrical behavior in a through-hole-compatible LQFP48 - making it a drop-in alternative where reflow constraints or thermal mass favor leaded packages.

FAQ
Does STM32F072C8T6TR support USB device mode without an external crystal?
Yes. It integrates a factory-trimmed 48 MHz HSI48 oscillator synchronized to USB Start-of-Frame (SOF) tokens via the Clock Recovery System (CRS), eliminating need for external crystal while maintaining ±0.25% USB timing accuracy across temperature and voltage ranges.
What is the maximum number of 5V-tolerant I/Os on this device?
STM32F072C8T6TR supports up to 68 5V-tolerant GPIOs across ports A, B, C, and D. These pins tolerate 5V inputs regardless of VDD level (2.0–3.6 V), enabling direct interface with legacy 5V peripherals without external level shifters.
Can the internal DAC drive a load directly, and what is its output compliance range?
The dual 12-bit DAC outputs (PA4/PA5) drive loads down to 5 kΩ with rail-to-rail output swing (0–VDD). Output impedance is ~15 kΩ; for low-impedance or precision applications, an external op-amp buffer is recommended per datasheet Section 6.3.17.
Is the CAN peripheral compatible with ISO 11898-1 (CAN 2.0B) and does it support automatic retransmission?
Yes. The integrated CAN controller fully complies with ISO 11898-1, supporting both standard (11-bit) and extended (29-bit) identifiers, programmable bit timing, and automatic retransmission on error frames - all without CPU intervention via dedicated transmit/receive FIFOs.
