Product details
Overview
STM32G071EBY6TR from STMicroelectronics is a 32-bit Arm® Cortex®-M0+ microcontroller in UFQFPN48 package, operating up to 64 MHz with 128 KB Flash, 36 KB SRAM, and integrated USB Type-C Power Delivery controller. It supports -40°C to 125°C operation, features two 12-bit DACs, 12-bit ADC with hardware oversampling, and four USARTs - used in industrial power adapters and smart USB-C PD sink implementations.
For engineers reviewing the STM32G071EBY6TR datasheet, STM32G071EBY6TR pinout, STM32G071EBY6TR application, or STM32G071EBY6TR equivalent, key selection criteria include its USB-C PD controller integration, 125°C extended temperature rating, dual DAC support for analog control loops, and 60 fast I/Os with 5 V tolerance - critical for compact, thermally constrained embedded power systems.
Technical Context
The device implements an Arm Cortex-M0+ core with MPU, supporting TrustZone-like memory protection via securable flash area and readout protection levels. Its clock system combines 4–48 MHz HSE, 32 kHz LSE with calibration, and ±1% internal 16 MHz RC with PLL - enabling precise timing for USB-C PD negotiation and real-time motor control.
Peripheral interconnect uses flexible routing via DMAMUX and GPIO alternate function mapping, allowing simultaneous use of multiple communication interfaces (e.g., I2C + SPI + LPUART) without resource conflict. The 14-timer suite includes two 128 MHz-capable advanced timers for high-resolution PWM and two low-power timers for RTC-alarm-triggered wakeups from Stop/Standby modes.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32G071CBT6 | LQFP48 package, same core/peripherals but no USB-C PD controller; 100-pin variant lacks UCPD pins. | Requires external PD IC for USB-C compliance; suitable only for non-PD applications like motor control or sensor hubs. | Select when USB-C PD is not required and LQFP48 mechanical fit is preferred over UFQFPN48. |
| STM32G081RBT6 | Same package and peripherals, but adds AES-128 crypto accelerator and true random number generator (TRNG). | Better suited for firmware signing, secure boot, and encrypted communication in certified PD implementations. | Choose when FIPS-compliant cryptography or secure key storage is mandated by end-product certification (e.g., UL 62368-1 Annex Q). |
Compared with STM32G071CBT6, the STM32G071EBY6TR saves board space and firmware effort via integrated PD controller; versus STM32G081RBT6, it trades cryptographic acceleration for lower cost and identical analog/motor control capability - ideal for cost-sensitive, high-volume USB-C PD sink designs.

Its internal 16 MHz RC oscillator has ±1% accuracy with PLL support, and the device maintains full functionality across its specified -40°C to 125°C ambient temperature range - validated per ST's DS12232 Rev 5 electrical characteristics tables (Sections 5.3.1, 5.3.8, 5.3.9).
Does the STM32G071EBY6TR support hardware-based USB-C Power Delivery without external components?
Yes - it integrates a dedicated USB-C Power Delivery controller with BMC transceiver logic, CC line monitoring, VCONN switching, and policy engine hardware. No external PD PHY or protocol IC is required; only passive components (resistors, capacitors) and a USB-C connector are needed to implement full PD 3.0 sink/source functionality per Section 3.24 and Table 2 of the datasheet.
How many analog-to-digital converter (ADC) channels does this MCU provide, and what is its effective resolution?
The STM32G071EBY6TR features a single 12-bit ADC with up to 16 external input channels and hardware oversampling that achieves up to 16-bit effective resolution. Conversion time is 0.4 µs, and the ADC supports differential mode, injected conversions, and automatic calibration - detailed in Sections 3.14 and 5.3.18 of DS12232 Rev 5.
What debug interface does the STM32G071EBY6TR support, and is SWD compatible with standard J-Link probes?
The device supports Serial Wire Debug (SWD) via dedicated SWDIO and SWCLK pins (PA13/PA14), fully compliant with ARM CoreSight standards.
