It brings USB OTG, 10×12-bit ADC channels, and 36 I/O lines into a 49-WLCSP package measuring 3×3.19 mm — a footprint that fits wearable and sensor-node PCBs where every square millimetre counts. The 100 MHz core executes a single-cycle multiply-and-accumulate. The 512 KB Flash and 128 KB RAM support a FreeRTOS image with a double-buffered ADC buffer. ## USB OTG — host or peripheral on the same pin ## 49-WLCSP — board area vs assembly yield The 49-WLCSP (3×3.19 mm) is a wafer-level chip-scale package with no mould compound. It saves board area but demands a controlled solder-paste stencil and reflow profile.","metaTitle":"STM32F411CEY3TR STM32F4 ARM Cortex-M4 MCU, 100MHz, 512KB Flash","metaDescription":"STMicroelectronics STM32F411CEY3TR 32-bit ARM Cortex-M4 MCU, 100MHz, 512KB Flash, 128KB RAM, USB OTG, -40 to 125°C, 49-WLCSP.
