Product details
Overview
STM32G051F8Y3TR from STMicroelectronics is a 32-bit Arm® Cortex®-M0+ microcontroller in a 20-pin TSSOP package, featuring 64 KB Flash, 18 KB SRAM, dual USARTs (one with LIN/ISO7816), two 12-bit DACs, and 12-bit ADC with hardware oversampling - deployed in industrial sensor nodes requiring low-power operation and integrated analog signal conditioning.
For engineers reviewing the STM32G051F8Y3TR datasheet, STM32G051F8Y3TR pinout, STM32G051F8Y3TR application, or STM32G051F8Y3TR equivalent, key selection criteria include its 64 MHz max CPU frequency, 1.7–3.6 V supply range, -40°C to 85°C operating temperature, and support for Stop/Standby low-power modes with RTC wakeup - critical for battery-powered edge devices.
Technical Context
The STM32G051F8Y3TR integrates an Arm Cortex-M0+ core with MPU, supporting TrustZone-like memory protection via readout protection (RDP) and securable flash area. Its clock system combines 4–48 MHz HSE, 32 kHz LSE with calibration, and internal 16 MHz HSI with PLL - enabling precise timing control across mixed-signal applications.
Peripheral interconnect uses a hierarchical AHB/APB bus matrix with DMAMUX routing; analog subsystem includes dual rail-to-rail comparators, VREFBUF, temperature sensor, and VBAT monitoring - allowing autonomous analog event detection without CPU intervention in low-power modes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M0+, 64 MHz max - delivers deterministic real-time response for control loops and protocol stacks. |
| Memory | 64 KB Flash (with securable area), 18 KB SRAM (16 KB with HW parity) - supports firmware updates and data logging with integrity checking. |
| Analog Peripherals | 12-bit ADC (16-channel, 0.4 µs conversion), two 12-bit DACs, two rail-to-rail comparators - enables closed-loop analog sensing and actuation. |
| Communication | Two USARTs (one ISO7816/LIN/IrDA capable), one LPUART, two I2C (Fast-mode Plus), two SPI (32 Mbit/s) - meets industrial serial interface requirements. |

Pinout & Package
STM32G051F8Y3TR is housed in a 20-pin TSSOP (Thin Shrink Small Outline Package) with 0.65 mm pitch, optimized for automated assembly and thermal performance in space-constrained designs.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32G031F8P6 | 32 KB Flash, no DAC, same TSSOP20 package and peripheral set | Lacks dual DACs and reduced SRAM (8 KB) - insufficient for analog waveform generation or multi-sensor buffering | Select when cost sensitivity outweighs need for DAC-based calibration or analog output features. |
| STM32G071F8Y3TR | 128 KB Flash, 36 KB SRAM, additional USB 2.0 FS interface, same pinout | Enables USB-CDC virtual COM port and larger firmware image storage - adds BOM cost and layout complexity | Choose when future-proofing for USB connectivity or larger application code size is required. |
Compared with STM32G031F8P6, the STM32G051F8Y3TR adds dual DACs and 10 KB more SRAM for analog-intensive tasks; versus STM32G071F8Y3TR, it trades USB and extra memory for lower cost and identical footprint - ideal for cost-sensitive, non-USB embedded control.

FAQ
What is the maximum operating frequency of the STM32G051F8Y3TR?
The STM32G051F8Y3TR operates at up to 64 MHz using its internal 16 MHz HSI oscillator with PLL multiplication or an external crystal. This frequency is fully supported across the entire 1.7–3.6 V supply range and -40°C to +85°C temperature grade, with timing verified per DS13303 Rev 4 Section 5.3.24.
Does this MCU support hardware encryption or secure boot?
The STM32G051F8Y3TR does not integrate AES or PKA accelerators, but supports secure boot via readout protection (RDP) Level 1/2, securable flash area, and 96-bit unique ID for key derivation. Bootloader authentication must be implemented in firmware using external crypto elements or software libraries.
Can the ADC and DAC operate simultaneously while the CPU is in Stop mode?
Yes - the ADC can perform single conversions triggered by LPTIM1 or RTC alarms in Stop mode, and DAC outputs remain active if powered. However, DMA transfer requires CPU wake; for autonomous operation, use comparator-triggered events with EXTI to minimize wake latency.
What debug interface does the STM32G051F8Y3TR use, and is JTAG supported?
The STM32G051F8Y3TR uses Serial Wire Debug (SWD) only - SWDIO and SWCLK pins support full programming, breakpoint setting, and real-time variable inspection. JTAG is not implemented; SWD provides equivalent functionality with fewer pins and lower PCB routing overhead.
