It packs 36 I/O lines, USB OTG, and a full peripheral set (I²C, SPI, UART, I²S, PWM, DMA) into a 49-WLCSP package measuring 3×3.19 mm — one of the smallest footprints in the STM32F4 value line. The 1.7 V to 3.6 V supply range and −40 to 85 °C operating temperature make it suitable for compact, battery-operated or thermally constrained designs in consumer, industrial, and IoT edge nodes. ## 100 MHz Cortex-M4 — what the speed buys you The 100 MHz core, combined with the single-cycle DSP extensions and FPU of the Cortex-M4, handles real-time control loops, sensor fusion, and audio processing. The 512 KB Flash and 128 KB RAM support RTOS and application code. The 49-WLCSP (3×3.19 mm) is a wafer-level chip-scale package with solder balls directly on the die pads. It saves PCB real estate but demands a controlled solder-paste stencil and reflow profile.","metaTitle":"ST STM32F411CEY6UTR ARM Cortex-M4 MCU, 100MHz, 512KB Flash","metaDescription":"STMicroelectronics STM32F411CEY6UTR — 32-bit ARM Cortex-M4 MCU at 100MHz, 512KB Flash, 128KB RAM, 36 I/O, USB OTG, 49-WLCSP, -40 to 85°C.
