It includes USB, UART/USART, I²C, SPI, LINbus, and HDMI-CEC interfaces. ## 48 MHz clock — timing margin for the bus 48 MHz is the ceiling for the Cortex-M0 core and the AHB/APB bus matrix. At this speed the part can service USB full-speed (12 Mbps) without external PHY, handle a 12-bit ADC sample sequence across 13 channels, and run a PWM loop with sub-microsecond resolution. The STM32F078CBU6 has an Active product status. The base number STM32F078 shares the same pinout across package variants.","metaTitle":"ST STM32F078CBU6 ARM Cortex-M0 MCU, 48MHz, 128KB Flash","metaDescription":"STM32F078CBU6 by STMicroelectronics: 32-bit ARM Cortex-M0, 48MHz, 128KB Flash, 16KB RAM, USB, -40°C to 85°C.
