STMicroelectronics STM32G050C8T6

Overview

STM32G050C8T6 from STMicroelectronics is an Arm® Cortex®-M0+ 32-bit microcontroller with 64 KB Flash, 18 KB SRAM, dual USARTs supporting LIN/IrDA/ISO7816, 12-bit ADC (0.4 µs conversion), and 14 timers-including two 128 MHz-capable advanced timers-operating from 2.0–3.6 V across –40°C to +85°C. It serves as a cost-optimized main controller in smart sensors and industrial I/O modules requiring low-power operation and integrated communication.

For engineers reviewing the STM32G050C8T6 datasheet, STM32G050C8T6 pinout, STM32G050C8T6 application, or STM32G050C8T6 equivalent, key selection criteria include its 48-pin LQFP package, 64 MHz max CPU frequency, hardware parity-checked SRAM, dual Fast-mode Plus I²C interfaces, and support for Stop/Standby wakeup via RTC alarm or external interrupt on 5 V-tolerant GPIOs.

Technical Context

The device integrates an Arm Cortex-M0+ core with MPU, enabling memory protection for real-time deterministic execution in safety-aware edge nodes. Its clock system combines four oscillator sources-4–48 MHz HSE, 32 kHz LSE with calibration, 16 MHz HSI with PLL, and 32 kHz LSI-allowing dynamic switching between high-accuracy and ultra-low-power timing domains.

Peripheral interconnect uses a hierarchical AHB/APB bus matrix with DMA request multiplexer (DMAMUX), enabling concurrent data movement across ADC, SPI, USART, and memory without CPU intervention. The 7-channel DMA controller supports flexible peripheral-to-memory and memory-to-peripheral transfers with configurable priority and address increment modes.

FAQ

What is the maximum operating frequency of the STM32G050C8T6?

The STM32G050C8T6 runs at up to 64 MHz using its internal 16 MHz HSI oscillator with PLL multiplication or external crystal sources. This frequency is fully supported across the entire –40°C to +85°C temperature range and 2.0–3.6 V supply voltage, with all peripherals functional at rated speed per DS13514 Rev 3 Section 5.3.1.

Does the STM32G050C8T6 support hardware encryption or secure boot?

No-the STM32G050C8T6 does not integrate AES, PKA, or secure boot engines. It offers readout protection (RDP) Level 1 and Level 2, memory write protection, and option byte configuration for basic firmware confidentiality, but lacks cryptographic accelerators found in G07x/G08x variants.

Can the STM32G050C8T6 drive a 5 V logic interface directly?

Yes-multiple GPIO pins (including PA0–PA15, PB0–PB15, and PC13–PC15) are explicitly specified as 5 V-tolerant in the datasheet (Section 5.3.14). These pins accept input voltages up to 5.5 V while powered from 2.0–3.6 V, enabling direct connection to 5 V peripherals without external level shifters.

What debug interface does the STM32G050C8T6 use, and how many pins are required?

The STM32G050C8T6 uses Serial Wire Debug (SWD), requiring only two physical pins: SWDIO (PA13) and SWCLK (PA14). No NRST connection is mandatory for basic debug, though it enables more reliable reset-and-halt sequences during development and production programming.
