STMicroelectronics STM32G050F6P6

Overview

STM32G050F6P6 from STMicroelectronics is an Arm® Cortex®-M0+ 32-bit microcontroller in TSSOP20 package, operating at 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, a 12-bit ADC (0.4 µs conversion), RTC with alarm, and supports 2.0–3.6 V supply. It targets cost-sensitive industrial control and smart sensor nodes requiring compact footprint and low-power operation.

For engineers reviewing the STM32G050F6P6 datasheet, STM32G050F6P6 pinout, STM32G050F6P6 application, or STM32G050F6P6 equivalent, key selection considerations include its TSSOP20 packaging, 20-pin I/O count with 5 V-tolerant capability, integrated hardware CRC, SWD debug support, and low-power Stop/Standby modes with RTC wakeup-critical for battery-backed embedded systems.

Technical Context

The device 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 ECC on SRAM) and 8 KB of SRAM (6 KB with parity). The clock system combines internal RC oscillators (16 MHz HSI, 32 kHz LSI), external crystal options (4–48 MHz HSE, 32.768 kHz LSE), and a PLL for precise frequency synthesis.

Peripheral interconnect uses AHB/APB buses with DMA controller (7 channels) and flexible remapping. Analog functions include temperature sensor, VREFINT, and VBAT monitoring. Power management enables Sleep, Stop (with RTC/backup register retention), and Standby modes, with POR/PDR and VBAT supply for RTC backup.

FAQ

What is the maximum operating frequency of the STM32G050F6P6?

The STM32G050F6P6 operates at up to 64 MHz using its internal 16 MHz HSI oscillator with PLL multiplication or an external crystal source. This frequency is fully supported across the full −40°C to +85°C temperature range and 2.0–3.6 V supply voltage, enabling deterministic real-time execution for control loops and communication stacks.

Does the STM32G050F6P6 support hardware encryption or secure boot?

No, the STM32G050F6P6 does not include hardware cryptographic accelerators (AES, SHA, PKA) or secure boot ROM. It provides readout protection (RDP) Level 1 and write protection for flash sectors, but lacks dedicated security peripherals found in the STM32G07x or STM32L5 series-making it suitable for non-security-critical applications where firmware confidentiality is managed externally.

Can the STM32G050F6P6 drive a standard 5 V LCD display directly?

No, the I/Os are 5 V-tolerant on input but output only up to VDD (max 3.6 V). To drive a 5 V LCD, external level-shifting circuitry (e.g., discrete MOSFETs or dedicated level translators like TXB0108) is required for data/control lines. However, its 5 V-tolerant inputs safely accept 5 V signals from the display's status or touch interface.

Is SWD debug supported on all pins, or only specific ones?

SWD debug is supported exclusively on PA13 (SWDIO) and PA14 (SWCLK); these pins are dedicated and cannot be remapped to other functions. They require 10 kΩ pull-up resistors on SWDIO and no external loading on SWCLK for reliable programming and debugging via ST-LINK or compatible probes.
