STMicroelectronics STM32G050C8T6TR

Overview

STM32G050C8T6TR from STMicroelectronics is a 32-bit Arm® Cortex®-M0+ microcontroller in LQFP48 package, operating up to 64 MHz with 64 KB Flash and 18 KB SRAM, supporting industrial control, smart sensors, and low-power IoT edge nodes via dual USARTs, 12-bit ADC (0.4 µs), and RTC with wakeup from Stop/Standby.

For engineers reviewing the STM32G050C8T6TR datasheet, STM32G050C8T6TR pinout, STM32G050C8T6TR application, or STM32G050C8T6TR equivalent, key selection criteria include 64 MHz CPU frequency, 2.0–3.6 V supply range, 44 fast I/Os (5 V-tolerant), dual I2C/Fast-mode Plus, and SWD debug support for rapid firmware validation.

Technical Context

The device integrates an Arm Cortex-M0+ core with MPU, supporting TrustZone-like memory protection and deterministic real-time execution. It features a multi-source clock system including 4–48 MHz HSE, 32 kHz LSE with calibration, 16 MHz HSI with PLL, and 32 kHz LSI - enabling precise timing control across Run, Sleep, Stop, and Standby modes.

Peripheral interconnect uses a hierarchical AHB/APB bus matrix with DMA controller (7 channels) and DMAMUX for flexible peripheral-to-memory transfers. Analog subsystem includes 12-bit ADC with hardware oversampling (up to 16-bit effective resolution), temperature sensor, VREFINT, and VBAT monitoring - all calibrated and specified over –40°C to +85°C.

FAQ

What is the maximum operating frequency and voltage range of the STM32G050C8T6TR?

The STM32G050C8T6TR operates at up to 64 MHz with a supply voltage range of 2.0 V to 3.6 V. This range supports direct connection to common 3.3 V power rails and single-cell Li-ion batteries (2.7–3.6 V nominal), while maintaining full peripheral functionality including ADC, timers, and communication interfaces across the entire voltage window.

Does the STM32G050C8T6TR support hardware CRC and memory protection?

Yes, it includes a dedicated CRC calculation unit supporting CRC-32 for firmware image verification and communication frame integrity. It also implements a Memory Protection Unit (MPU) that enforces privilege levels and memory access permissions - enabling secure partitioning of application code, bootloader, and critical data sections in safety-aware designs.

How many I/O pins are 5 V-tolerant, and which packages support them?

Up to 25 I/O pins on the STM32G050C8T6TR are 5 V-tolerant, confirmed in the LQFP48 package (pinout Figure 5 in DS13514 Rev 3). These include PA0–PA15, PB0–PB10, and PC13–PC15. Tolerance applies regardless of VDD voltage (2.0–3.6 V), allowing safe interfacing with 5 V peripherals without external level-shifting circuitry.

What low-power modes are available, and what is the lowest typical current consumption?

The device supports Sleep, Stop (0 and 1), and Standby modes. In Stop 1 mode with RTC running and VBAT supplied, typical current consumption is ≤0.33 µA at 25°C - verified in Table 28 of DS13514 Rev 3. This enables multi-year operation on CR2032 coin cells in applications like utility meters and remote sensors.
