Product details
Overview
STM32G051G8U6TR from STMicroelectronics is a 32-bit Arm® Cortex®-M0+ microcontroller in UFQFPN28 package, featuring 64 KB Flash, 18 KB SRAM, dual USARTs with LIN/IrDA support, 12-bit ADC (0.4 µs conversion), and two 12-bit DACs. It operates from 1.7–3.6 V across –40°C to 125°C and targets compact industrial sensor nodes requiring integrated analog I/O and low-power connectivity.
For engineers reviewing the STM32G051G8U6TR datasheet, STM32G051G8U6TR pinout, STM32G051G8U6TR application, or STM32G051G8U6TR equivalent, key selection criteria include its 28-pin UFQFPN footprint, dual DAC + comparator analog subsystem, 125°C extended temperature rating, and support for ISO7816, LIN, and hardware oversampling-critical for battery-powered edge sensing and motor control interfaces.
Technical Context
The device integrates an Arm Cortex-M0+ core running up to 64 MHz with MPU, 7-channel DMA, and nested vectored interrupt controller (NVIC) supporting real-time deterministic response. Its memory subsystem includes 64 KB flash with securable area and 18 KB SRAM (16 KB with hardware parity), enabling robust firmware integrity and data reliability in safety-aware applications.
Peripherals are tightly coupled via an AHB/APB interconnect matrix: dual I2C (one Fast-mode Plus), two SPIs (32 Mbit/s), LPUART, RTC with calendar and alarm, and 14 timers-including two 128 MHz-capable advanced timers for motor control and two low-power timers for precise wake-up scheduling in Stop/Standby modes.
Key Specifications

Pinout & Package
STM32G051G8U6TR uses a 28-pin Ultra-Fine Pitch Quad Flat No-lead (UFQFPN28) package, 4 mm × 4 mm, 0.5 mm pitch, with exposed thermal pad. Pinout conforms to ST's standard G051x8 mapping for UFQFPN28 (A0B0 variant), supporting full GPIO remapping and multiple peripheral alternate functions per pin.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VSS | Power supply / Ground | Dual VDD/VSS pairs ensure stable core/peripheral rail decoupling; VSS pins adjacent to analog inputs reduce noise coupling. |
| PA0–PA15, PB0–PB11, PC13–PC15 | General-purpose I/O | 44 fast I/Os total; up to 28 available in UFQFPN28; all support external interrupts and 5 V-tolerance on selected pins (e.g., PA0–PA7). |
| PA2/PA3, PA9/PA10 | USART TX/RX | Dual USARTs: USART1 (PA9/PA10) supports ISO7816/LIN/IrDA; USART2 (PA2/PA3) adds auto-baud detection and wake-up capability. |
| PA4–PA7 | ADC IN1–IN4 | Four dedicated analog input channels mapped to PA4–PA7 - enables direct connection of resistive sensors or voltage dividers without external mux. |
| PA4, PA5 | DAC1_OUT, DAC2_OUT | Independent DAC outputs routed to PA4 (DAC1) and PA5 (DAC2) - allows differential analog output or independent signal generation. |
| PA1, PA0 | COMP1_INP, COMP2_INP | Comparator non-inverting inputs tied to PA0/PA1 - supports rail-to-rail analog window detection or zero-crossing sensing with programmable hysteresis. |
Key Features
| Feature | Design Value |
|---|---|
| Hardware CRC unit | Accelerates firmware image verification and communication frame checksums without CPU overhead. |

FAQ
What is the maximum operating frequency and supported voltage range?
The STM32G051G8U6TR runs at up to 64 MHz using its internal 16 MHz HSI oscillator with PLL, or external crystal sources. It operates across 1.7 V to 3.6 V supply voltage, with built-in programmable voltage detector (PVD) and brownout reset (BOR) to maintain reliable operation down to 1.7 V - validated per DS13303 Rev 4 Section 5.3.1.
Does this MCU support hardware encryption or secure boot?
It includes a securable flash area and readout protection (RDP) levels, enabling firmware IP protection and secure boot enforcement. While it lacks dedicated AES/SHA accelerators (unlike G071), its memory protection unit (MPU), option byte configuration, and 96-bit unique ID provide foundational security for device authentication and code integrity - detailed in Sections 3.2 and 3.3.1 of the datasheet.
How many analog-to-digital converter (ADC) channels are available, and what is their resolution?
The device integrates a single 12-bit ADC with up to 16 external input channels (e.g., PA0–PA7, PB0–PB1, PC0–PC5). Conversion time is 0.4 µs at maximum speed, and hardware oversampling extends effective resolution to 16 bits. Accuracy is ±1 LSB INL/DNL across –40°C to 125°C, per Table 59 in DS13303 Rev 4.
What debug interface does STM32G051G8U6TR support?
It supports Serial Wire Debug (SWD) via SWCLK and SWDIO pins (PA14/PA13), compliant with ARM CoreSight standards. This enables full JTAG/SWD debugging, flash programming, and real-time tracing using ST-LINK v2/v3 probes - confirmed in Section 3.24.1 and Table 12 of the datasheet.
