Product details
Overview
STM32G071CBT6TR from STMicroelectronics is a 32-bit Arm® Cortex®-M0+ microcontroller with 128 KB Flash, 36 KB SRAM, and integrated USB Type-C Power Delivery controller. It operates from 1.7–3.6 V, supports -40°C to 125°C extended temperature range, and delivers up to 64 MHz CPU frequency. Used in smart power adapters, industrial sensor nodes, and battery-powered USB-C PD controllers where compact footprint and low-power operation are critical.
For engineers reviewing the STM32G071CBT6TR datasheet, STM32G071CBT6TR pinout, STM32G071CBT6TR application, or STM32G071CBT6TR equivalent, key selection criteria include its dual 12-bit DACs, 14-timer suite (including two 128 MHz-capable advanced timers), 4x USARTs with ISO7816/LIN support, 12-bit 0.4 µs ADC with hardware oversampling, and LQFP64 package compatibility for high-pin-count control tasks.
Technical Context
The STM32G071CBT6TR integrates an Arm Cortex-M0+ core with MPU, supporting memory protection and secure boot via securable flash area. 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 a flexible AHB/APB matrix with 7-channel DMA and DMAMUX routing. Analog subsystem includes two rail-to-rail comparators, voltage reference buffer (VREFBUF), temperature sensor, and VBAT monitoring - all validated for operation across full industrial temperature range and supply voltage swing.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32G071RBT6 | LQFP64 same pinout, but rated only to 85°C ambient - lacks extended temperature qualification. | Suitable for commercial-grade consumer adapters, not industrial or automotive under-hood use. | Select when cost sensitivity outweighs extended temp requirement and no VBAT/RTC backup is needed. |
| STM32G081RBT6 | Same package and pinout, adds AES-128 crypto accelerator and true random number generator (TRNG). | Required for FIPS-compliant secure boot, encrypted OTA, or PKI-based device identity in regulated markets. | Choose when cryptographic acceleration and hardware entropy are mandatory for security certification. |
Compared with STM32G071CBT6TR, the RBT6 variant trades extended temperature for lower cost in benign environments, while the G081RBT6 adds cryptographic IP at higher unit cost - making the CBT6TR optimal for thermally demanding USB-C PD and motor control where security is secondary to analog performance and thermal resilience.

FAQ
What is the maximum operating frequency and voltage range for STM32G071CBT6TR?
The STM32G071CBT6TR operates at up to 64 MHz CPU frequency across a 1.7–3.6 V supply range. Its internal voltage regulator supports dynamic voltage scaling, and all electrical characteristics - including ADC accuracy and timer jitter - are guaranteed across this full voltage and temperature (-40°C to +125°C) envelope per DS12232 Rev 5.
Does STM32G071CBT6TR support USB-C Power Delivery without external components?
Yes - it integrates a complete USB-C Power Delivery 3.0 controller including CC logic, BMC physical layer, and protocol engine. Only passive components (resistors, capacitors) and a USB-C connector are required; no external PD controller IC or level-shifting circuitry is needed for standard 5–20 V profile negotiation.
How many analog inputs does the 12-bit ADC support, and what is its conversion speed?
The integrated 12-bit ADC supports up to 16 external channels with 0.4 µs conversion time (2.5 MSPS), plus internal channels (temperature sensor, VREFINT, VBAT). Hardware oversampling extends resolution to 16 bits at reduced effective sampling rate - validated in DS12232 Section 3.14 and Table 58.
Is the LQFP64 package of STM32G071CBT6TR lead-free and RoHS compliant?
Yes - the LQFP64 package is ECOPACK2-compliant, meeting RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Lead-free matte tin finish, halogen-free molding compound, and fully traceable material declarations are provided in ST's official product change notifications and packaging datasheets.
