Product details
Overview
STM32F072C8U6TR 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 precise analog signal handling - such as industrial sensor nodes and USB-connected human interface devices.
For engineers reviewing the STM32F072C8U6TR datasheet, STM32F072C8U6TR pinout, STM32F072C8U6TR application, or STM32F072C8U6TR equivalent, key selection considerations include its internal 48 MHz oscillator with automatic USB trimming, 5V-tolerant GPIOs (up to 68 pins), dual 12-bit DAC channels, and support for capacitive touch sensing across 24 channels - all in a compact UFQFPN48 package.
Technical Context
The STM32F072C8U6TR integrates a single-core Arm Cortex-M0 CPU with tightly coupled NVIC and SysTick timer, paired with a multi-source clock system including internal 48 MHz HSI48 (USB-trimmed), 8 MHz HSI, 40 kHz LSI, and external 4–32 MHz HSE/32.768 kHz LSE oscillators. Its power architecture supports three low-power modes (Sleep, Stop, Standby) with VBAT backup for RTC and registers.
Peripheral integration centers on real-time control and connectivity: one advanced-control timer (TIM1) for six-channel PWM, seven general-purpose timers, two I²C interfaces (one with SMBus/PMBus), four USARTs (two with ISO7816/LIN/IrDA), two SPI/I²S interfaces, CAN 2.0B, and a full-speed USB 2.0 interface compliant with Battery Charging Detection (BCD) and Link Power Management (LPM).
Key Specifications

|---|---|
| CPU Core | Arm Cortex-M0, 48 MHz max - enables deterministic real-time execution with Thumb-2 instruction set and 3-stage pipeline. |
| Memory | 64 KB Flash + 16 KB SRAM with HW parity - sufficient for firmware with USB/CAN stacks and safety-critical data integrity. |
| USB Interface | Crystal-less USB 2.0 FS - eliminates external crystal cost and board space while maintaining ±0.25% accuracy via HSI48 auto-trimming. |
| Analog Peripherals | 1×12-bit ADC (16 ch, 1 µs), 2×12-bit DAC, 2×comparators - supports closed-loop control, sensor signal conditioning, and audio waveform generation. |

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, 6 KB SRAM, LQFP48 only | Lacks USB/CAN - suitable for cost-sensitive, non-connectivity applications like basic motor control | Select when USB/CAN are unnecessary and BOM cost is primary constraint. |
| STM32F072RBT6 | LQFP64 package, 128 KB Flash, 16 KB SRAM, same peripherals | Higher pin count and memory - enables larger firmware, more GPIOs, and complex peripheral routing | Choose for designs needing >37 I/Os or future-proofing with extra Flash for OTA updates. |
Compared with STM32F072C8U6TR, the STM32F070F6P6 sacrifices USB/CAN and memory for lower cost and smaller footprint, while the STM32F072RBT6 offers identical functionality in a larger package with double the Flash - making it ideal for scalable designs where pin expansion or firmware headroom is critical.

FAQ
Does STM32F072C8U6TR support crystal-less USB operation?
Yes. The device integrates an internal 48 MHz HSI48 oscillator with automatic trimming based on USB Start-of-Frame (SOF) synchronization, achieving ±0.25% accuracy without an external crystal. This is confirmed in Section 3.6 and Table 43 of DS9826 Rev 6.
What is the maximum number of 5V-tolerant I/Os on the UFQFPN48 package?
The STM32F072C8U6TR in UFQFPN48 supports 32 5V-tolerant I/Os, as specified in Table 14 (pin definitions) and Section 3.7 of DS9826 Rev 6. These include all pins except VDD/VDDA/VSS/VSSA, BOOT0, NRST, and the USB DP/DM pins.
Can the internal DAC outputs drive a 1 kΩ load directly?
No. Each DAC channel has a typical output impedance of 15 kΩ and is specified to drive loads ≥5 kΩ (Table 60). Driving a 1 kΩ load causes significant gain error and settling time degradation; an external op-amp buffer is required for low-impedance applications.
Is the STM32F072C8U6TR qualified for automotive applications?
No. The STM32F072C8U6TR is rated for industrial temperature range (–40 °C to +85 °C) and is not AEC-Q100 qualified. For automotive use, ST recommends the pin-compatible STM32F078xx series (AEC-Q100 Grade 2) or STM32G071xx (Grade 2), which share similar peripherals but meet automotive reliability standards.
