An internal lifecycle flag marks this as eol_hot, yet the official manufacturer status is Active. This part may be in a quiet phase-out window — not yet formally discontinued, but not aggressively stocked by franchised distributors. ## Connectivity and peripherals in 6 I/O The STM32G031J4M6 includes I2C, SPI, and UART/USART interfaces — enough for a small sensor hub or a LIN-bus node in automotive auxiliary systems. The 8-channel 12-bit ADC shares pins with the digital I/O, so you trade ADC channels for serial pins depending on the application.","metaTitle":"ST STM32G031J4M6 ARM Cortex-M0+ MCU, 64 MHz, 16 KB Flash, 8-SOIC","metaDescription":"STM32G031J4M6 32-bit MCU, 64 MHz Cortex-M0+, 16 KB Flash, 8K x 8 RAM, I2C/SPI/UART, 8-SOIC.
