The 32-bit data path handles 32-bit arithmetic in one cycle, so a PID loop or a simple state machine fits without the overhead of a 16-bit core. ## Memory budget: 32 KB flash, 4 KB SRAM 32 KB of on-chip flash (32K x 8) and 4 KB SRAM (4K x 8) set the firmware ceiling. For a motor-control or sensor-hub application, the flash holds the application code plus a bootloader; the SRAM covers the stack, a few ring buffers, and the ADC conversion results. If the firmware exceeds 32 KB, step up to the STM32F038x6 or STM32F042 variants in the same package. ## Package and board-fit: 28-UFQFPN (5x5 mm) Housed in a 28-lead UFQFPN (5x5 mm) — a thin, fine-pitch QFN with an exposed pad. ## Peripherals and I/O 22 I/O lines, including a 10-channel 12-bit ADC, two I²C, two SPI, one UART/USART with LIN and IrDA support, plus a PWM timer and a watchdog. The DMA engine moves ADC results to memory without CPU intervention — useful for continuous sensor monitoring. The I²S interface handles audio streaming if needed.","metaTitle":"STM32F038G6U6 STM32F0 MCU, 48MHz, 32KB Flash, 28-UFQFPN","metaDescription":"STM32F038G6U6 ARM Cortex-M0 MCU, 48MHz, 32KB flash, 4KB SRAM, 28-UFQFPN (5x5mm).
