The 128 KB Flash is sized for firmware images that include a bootloader, application code, and a small parameter storage area, while the 32 KB SRAM supports moderate data buffers and stack usage typical of motor control, sensor fusion, or human-machine interface nodes. ## Package and supply — design-in checklist The 48-LQFP footprint is common across the STM32F0 value-line density options, so a board layout can accommodate multiple Flash/RAM variants without a PCB spin.","metaTitle":"STM32F091CBT7 ARM Cortex-M0 MCU, 48 MHz, 128 KB Flash","metaDescription":"STM32F091CBT7 32-bit MCU with 48 MHz Cortex-M0 core, 128 KB Flash, 32 KB SRAM, CAN, 13-ch 12-bit ADC, -40 to 105 °C.
