The part includes 12-bit ADC (17 channels) and two 12-bit DACs, so analog-front-end designs can stay on-chip without external converters.","metaTitle":"ST STM32G071CBU3 ARM Cortex-M0+ MCU, 64 MHz, 128 KB Flash","metaDescription":"STMicroelectronics STM32G071CBU3 32-bit MCU, 64 MHz Cortex-M0+, 128 KB Flash, 36 KB RAM, -40 to 125°C, 48-UFQFPN.
