The 4 KB RAM limits buffering, so this part is not suited for heavy data logging or TCP/IP stacks. The 28-UFQFN package (4x4 mm) is a fine-pitch, leadless land-grid array — it requires a well-controlled reflow profile and X-ray inspection of solder joints. The 13-channel 12-bit ADC handles analog inputs like temperature sensors or potentiometers without an external converter.","metaTitle":"ST STM32F031G4U7TR ARM Cortex-M0 MCU, 48MHz, 16KB Flash","metaDescription":"STMicroelectronics STM32F031G4U7TR 32-bit MCU with ARM Cortex-M0 core at 48MHz, 16KB Flash, 4KB RAM, 23 I/O, -40 to 105°C.
