Product details
Overview
STM32G071KBT6TR from STMicroelectronics is a 32-bit Arm® Cortex®-M0+ microcontroller in LQFP32 package, operating up to 64 MHz with 128 KB Flash, 36 KB SRAM, and integrated USB Type-C Power Delivery controller. It features two 12-bit DACs, 12-bit ADC (0.4 µs conversion), four USARTs (including ISO7816/LIN support), and operates across 1.7–3.6 V supply at -40°C to 125°C for industrial motor control and smart power interface applications.
For engineers reviewing the STM32G071KBT6TR datasheet, STM32G071KBT6TR pinout, STM32G071KBT6TR application, or STM32G071KBT6TR equivalent, key selection criteria include its dual DAC capability, USB Type-C PD controller integration, 125°C extended temperature rating, and LQFP32 footprint compatibility with space-constrained embedded power management designs.
Technical Context
The device implements an Arm Cortex-M0+ core with Memory Protection Unit (MPU), supporting TrustZone-like secure execution isolation. Its clock system integrates four oscillators: 4–48 MHz HSE, 32 kHz LSE with calibration, 16 MHz HSI (±1%), and 32 kHz LSI (±5%), enabling precise RTC operation and low-power wakeup timing.
Peripheral interconnect uses a hierarchical AHB/APB bus matrix with DMA request multiplexer (DMAMUX) and flexible GPIO remapping. The 14-timer suite includes two 128 MHz-capable advanced timers (TIM1/TIM17), one 32-bit general-purpose timer, and two low-power timers (LPTIM1/LPTIM2) optimized for Stop/Standby mode operation with sub-microsecond wakeup latency.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32G081KBT6 | 128 KB Flash, 36 KB SRAM, same package - adds AES-128 accelerator and additional 2x USARTs. | Required for firmware encryption or multi-protocol communication (e.g., simultaneous Modbus RTU + USB-C PD). | Select when cryptographic acceleration or extra serial interfaces are mandatory; otherwise identical footprint and code compatibility. |
| STM32F072CBT6 | 48 MHz Cortex-M0, 128 KB Flash, 16 KB SRAM, LQFP48 - lacks USB-C PD controller and 125°C rating. | Suitable for cost-sensitive industrial HMI where USB-C negotiation is absent and ambient temperature stays ≤85°C. | Choose only if USB-C PD is unnecessary and thermal constraints permit lower temperature grade; requires PCB redesign due to LQFP48 vs LQFP32. |
Compared with STM32G071KBT6TR, the STM32G081KBT6 adds security features without sacrificing footprint, while the STM32F072CBT6 trades USB-C PD integration and extended temperature for lower cost and legacy peripheral compatibility - making the G071 optimal for space-constrained, thermally demanding USB-C power systems.

FAQ
What is the maximum operating frequency and voltage range of the STM32G071KBT6TR?
The STM32G071KBT6TR operates at up to 64 MHz using its internal 16 MHz HSI oscillator with PLL multiplication. Its supply voltage range is strictly 1.7 V to 3.6 V across all operating temperatures; operation outside this range risks functional failure or permanent damage per Section 5.2 Absolute Maximum Ratings in DS12232 Rev 5.
Does the STM32G071KBT6TR support USB-C Power Delivery communication without external components?
Yes - it integrates a dedicated USB Type-C Power Delivery controller with hardware SOP message handling, VCONN switching logic, and fault monitoring circuitry. No external PD PHY or transceiver is required; only passive magnetics and ESD protection diodes are needed for full USB-C PD 3.0 compliance in sink/source roles.
How many analog-to-digital converter channels does the STM32G071KBT6TR provide, and what is its sampling speed?
The device features a single 12-bit ADC with up to 16 external input channels and 3 internal channels (temperature sensor, VREFINT, VBAT). Its maximum sampling rate is 2.5 MSPS (0.4 µs conversion time) at full resolution, confirmed in Section 3.14 and Table 58 of DS12232 Rev 5, with hardware oversampling extending effective resolution to 16 bits.
Is the STM32G071KBT6TR pin-compatible with other STM32G0-series MCUs in LQFP32 package?
No - while the LQFP32 footprint is shared across several G0 devices (e.g., STM32G031K8T6, STM32G041K8T6), pin functions differ significantly. For example, PA4/PA5 serve as DAC outputs on the G071KBT6TR but as standard GPIOs on the G031K8T6. Always verify alternate function mapping per Table 12 in DS12232 Rev 5 before substitution.
