The DMA controller offloads peripheral-to-memory transfers, keeping the Cortex-M0 free for loop code. Peripherals include PWM timers, a watchdog timer, POR, and I²S audio interface — the I²S block is useful for audio playback or codec communication in a simple voice prompt system.","metaTitle":"ST STM32F051C4T6 ARM Cortex-M0 MCU, 48 MHz, 16 KB Flash","metaDescription":"STMicroelectronics STM32F051C4T6 32-bit MCU, 48 MHz ARM Cortex-M0, 16 KB Flash, 8 KB SRAM, 48-LQFP, -40 to 85°C.
