Overview
STM32G050C6T6 from STMicroelectronics is a 32-bit Arm® Cortex®-M0+ microcontroller in LQFP48 package, operating up to 64 MHz with 32 KB Flash and 8 KB SRAM. It integrates dual USARTs (one with LIN/ISO7816), two I²C interfaces (Fast-mode Plus), two SPIs (32 Mbit/s), 12-bit ADC (16-channel), RTC with alarm, and 14 timers including advanced motor control timer TIM1. It targets cost-sensitive industrial sensor nodes and smart metering front-ends requiring low-power operation across -40°C to +85°C.
For engineers reviewing the STM32G050C6T6 datasheet, STM32G050C6T6 pinout, STM32G050C6T6 application, or STM32G050C6T6 equivalent, key selection criteria include Flash/RAM size, 5 V-tolerant GPIO count (up to 44), low-power mode wakeup time (≤3.5 µs from Stop), integrated analog peripherals (ADC + temperature sensor + VREFINT), and SWD debug support for rapid firmware validation.
Technical Context
The STM32G050C6T6 implements an Arm Cortex-M0+ core with MPU, supporting Thumb-2 instruction set and single-cycle multiplication. Its memory subsystem includes 32 KB of flash with readout protection and hardware CRC unit, plus 8 KB SRAM with optional parity checking.
Power management features POR/PDR, three low-power modes (Sleep, Stop, Standby), and VBAT supply for RTC/backup registers. Clock system combines 4–48 MHz HSE, 32 kHz LSE with calibration, 16 MHz HSI with PLL, and 32 kHz LSI - enabling precise timing control for real-time sensor sampling and communication scheduling.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32G030F6P6 | 24-pin TSSOP, 16 KB Flash, 4 KB SRAM, no VBAT, no RTC calendar | Lacks calendar RTC and backup registers - unsuitable for time-stamped logging or battery-backed operation | Select only for ultra-low-cost, space-constrained designs where timekeeping is handled externally. |
| STM32G070CBT6 | LQFP48, 128 KB Flash, 16 KB SRAM, USB 2.0 FS, more timers and ADC channels | Includes USB interface and larger memory - adds complexity and cost for non-USB applications | Choose when future firmware expansion or host connectivity is required; otherwise over-spec'd for basic control tasks. |
Compared with STM32G030F6P6, the STM32G050C6T6 adds calendar RTC and VBAT support for autonomous timekeeping; versus STM32G070CBT6, it reduces Flash/SRAM and omits USB to lower cost and power in fixed-function embedded controllers.

FAQ
What is the maximum operating frequency and supported voltage range?
The STM32G050C6T6 operates at up to 64 MHz with a supply voltage range of 2.0 V to 3.6 V. This allows direct compatibility with standard 3.3 V industrial rails and single-cell Li-ion batteries. The core uses an internal PLL fed by the 16 MHz HSI oscillator or external crystal sources, ensuring stable timing across temperature and voltage variations per DS13514 Rev 3 Section 5.3.9.
Does this MCU support hardware encryption or secure boot features?
No, the STM32G050C6T6 does not include hardware cryptographic accelerators (AES, SHA, PKA) or secure boot ROM. It offers readout protection (RDP) Level 1 and Level 2, memory protection unit (MPU), and option bytes for basic firmware security. For applications requiring certified secure boot or encrypted firmware updates, ST's STM32G0B1 or STM32L5 series are recommended alternatives.
How many I²C interfaces are available and what are their speed capabilities?
The STM32G050C6T6 integrates two I²C-bus interfaces, both supporting Fast-mode Plus (1 Mbit/s) with extra current sink capability. One interface supports SMBus/PMBus protocols and wakeup from Stop mode. These are implemented per Section 3.17 of DS13514 Rev 3 and verified in Table 8, enabling reliable communication with temperature sensors, EEPROMs, and power monitors without external bus buffers.
Is SWD debug supported and what pins are required?
Yes, serial wire debug (SWD) is fully supported using dedicated SWDIO (PA13) and SWCLK (PA14) pins. No additional pins are required - reset (NRST) is optional for debug initialization. This 2-pin interface enables full programming, real-time tracing, and register-level debugging per Section 3.20.1 of the datasheet, with no need for JTAG header footprint.
