DMA offloads the Cortex-M0 core during high-rate data transfers — the ADC can fill a buffer in SRAM without CPU intervention, leaving the core free for control arithmetic.","metaTitle":"STM32F051K6U6TR STM32F0 MCU, 48 MHz, 32 KB Flash, 32-UFQFPN","metaDescription":"STMicroelectronics STM32F051K6U6TR ARM Cortex-M0 MCU, 48 MHz, 32 KB Flash, 8 KB RAM, 27 I/O, 12-bit ADC/DAC, -40 to 85°C, 32-UFQFPN.
