STMicroelectronics STM32G071R8T6

Overview

STM32G071R8T6 from STMicroelectronics is a 32-bit Arm® Cortex®-M0+ microcontroller with 64 MHz max CPU frequency, 128 KB flash, 36 KB SRAM, and integrated USB Type-C Power Delivery controller. It features dual 12-bit DACs, 12-bit ADC (0.4 µs conversion), four USARTs (two with ISO7816/LIN/IrDA), and operates across 1.7–3.6 V supply in industrial temperature range (−40°C to 105°C). Used in smart power adapters, USB-C PD sink controllers, and compact industrial HMI nodes.

For engineers reviewing the STM32G071R8T6 datasheet, STM32G071R8T6 pinout, STM32G071R8T6 application, or STM32G071R8T6 equivalent, key selection considerations include USB-C PD controller integration, 60 GPIOs with 5 V tolerance, low-power timer support for battery-backed RTC, and hardware CRC/MPU for secure firmware execution.

Technical Context

The STM32G071R8T6 implements an Arm Cortex-M0+ core with Memory Protection Unit (MPU) and supports TrustZone-like secure boot via readout protection (RDP) levels and securable flash area. Its clock system integrates four oscillators: 4–48 MHz HSE, 32 kHz LSE with calibration, 16 MHz HSI (±1%), and 32 kHz LSI (±5%).

Peripheral interconnect uses a multi-layer AHB/APB bus matrix enabling concurrent DMA transfers and peripheral access. The 14-timer suite includes two 128 MHz-capable advanced timers (TIM1/TIM17), one 32-bit general-purpose timer (TIM2), and two low-power timers (LPTIM1/LPTIM2) optimized for Stop/Standby wakeup with sub-microsecond latency.

FAQ

Does STM32G071R8T6 support USB-C Power Delivery sink functionality out of the box?

Yes. The integrated USB-C Power Delivery controller supports sink role operation per USB PD 3.1 specification, including CC line monitoring, SOP message handling, and VBUS discharge control. Firmware must implement policy engine using ST's X-CUBE-PD middleware, but no external PD PHY or transceiver is required.

What is the maximum operating temperature rating for STM32G071R8T6 in LQFP64 package?

The STM32G071R8T6 in LQFP64 package is qualified for industrial temperature range: −40°C to 105°C ambient. This is confirmed in Table 21 (DS12232 Rev 5, p.56) and applies to all LQFP64 variants regardless of flash density (x8/xB suffix).

Can the 12-bit DAC outputs drive a 1 kΩ load directly?

No. Each DAC output has a maximum source/sink capability of ±5 mA (per DS12232 Rev 5, Table 61). Driving a 1 kΩ load at 3.3 V requires 3.3 mA, which is within spec-but output impedance rises above 100 Ω beyond 2.5 V, so external op-amp buffering is recommended for precision applications.

Is the STM32G071R8T6 pin-compatible with other STM32G071 variants in LQFP64?

Yes. All STM32G071x8/xB devices in LQFP64 (e.g., STM32G071CB, STM32G071RB) share identical pinout and electrical characteristics. Flash size (64 KB vs 128 KB) and temperature grade (85°C vs 105°C) are the only functional differences-enabling drop-in replacement during design iteration.
