The peripheral list includes I²S, multiple SPI/UART/USART, USB, and HDMI-CEC — enough connectivity for a smart actuator, a USB-to-serial bridge, or a small IoT edge node. ## Package and mounting — 64-UFBGA (5x5) The 64-UFBGA (5x5 mm) package saves board area versus a 64-pin LQFP. Reflow-only assembly is required. ## Lifecycle and sourcing — EOL hot, sourced to order This part carries an EOL hot lifecycle status. That means ST has issued an end-of-life notice; the last-time-buy window may be closed or closing. For new designs, ST recommends migrating within the STM32G0 series — the base product number STM32G081 is the family anchor, and a pin-compatible variant with the same package and memory map may still be active. For existing BOM lines, we source this through independent distribution against an RFQ.","metaTitle":"ST STM32G081RBI6 ARM Cortex-M0+ MCU, 64 MHz, 128 KB Flash","metaDescription":"STMicroelectronics STM32G081RBI6 32-bit MCU, 64 MHz Cortex-M0+, 128 KB Flash, 36K x 8 RAM, 60 I/O, 64-UFBGA, -40 to 85°C.
