Product details
Overview
STM32G050K6T6 from STMicroelectronics is an Arm® Cortex®-M0+ 32-bit microcontroller in TSSOP20 package, delivering up to 64 MHz operation, 64 KB Flash, and 18 KB SRAM. It integrates dual USARTs with LIN/IrDA support, a 12-bit ADC (0.4 µs conversion), seven-channel DMA, and RTC with alarm-targeting cost-sensitive industrial control and smart sensor nodes.
For engineers reviewing the STM32G050K6T6 datasheet, STM32G050K6T6 pinout, STM32G050K6T6 application, or STM32G050K6T6 equivalent, key selection criteria include its 20-pin TSSOP footprint, 2.0–3.6 V supply range, 5 V-tolerant I/Os, low-power Stop/Standby modes, and dual I²C interfaces with Fast-mode Plus (1 Mbit/s) capability.
Technical Context
The STM32G050K6T6 implements an Arm Cortex-M0+ core with MPU, supporting TrustZone-like memory protection and deterministic real-time execution. Its clock system combines 4–48 MHz HSE, 32 kHz LSE with calibration, and internal 16 MHz RC with PLL for flexible timing synthesis.
Peripheral interconnect uses a hierarchical AHB/APB bus matrix enabling concurrent DMA transfers and peripheral access. The 14-timer suite includes two 128 MHz-capable advanced timers for motor control, plus dedicated low-power timers for RTC wakeup and periodic event generation.
Key Specifications

FAQ
Does STM32G050K6T6 support USB device functionality?
No. The STM32G050K6T6 lacks a USB PHY and dedicated USB controller. It does not support native USB device or host operation. Connectivity relies on external transceivers via USART (e.g., CP2102 for USB-to-UART bridging) or SPI/I²C peripherals. USB capability begins with higher-density G0 variants like STM32G071.
What is the maximum operating frequency of the internal 16 MHz RC oscillator?
The internal 16 MHz RC oscillator (HSI16) operates at 16 MHz ±1% over temperature and voltage, as specified in Section 5.3.8 of DS13514 Rev 3. When used with the PLL, it can generate system clocks up to 64 MHz. No external trimming is required-the factory calibration value is stored in system memory and automatically applied at startup.
Can PA11 and PA12 be used as USB DP/DM on this part?
No. PA11 and PA12 on the STM32G050K6T6 are configured exclusively as USART1_CK and USART1_DE, respectively-not as USB DP/DM. USB functionality is absent from this variant's silicon; those pins have no USB alternate function mapping in the device's AFIO register set or pin description table (Section 4, Table 12).
Is the 12-bit ADC capable of differential input measurements?
No. The STM32G050K6T6's ADC supports only single-ended input configuration across its 16 external channels (e.g., ADC_IN0–ADC_IN15). It does not implement differential pair inputs or programmable gain amplifier (PGA) stages. Differential measurement requires external signal conditioning or migration to G07x/G0Bx series with dual-sampling ADCs.
