STM32F411CEU6

STM32F411CEU6 is the STMicroelectronics STM32F411CE access-line microcontroller in UFQFPN-48 (7 x 7 x 0.55 mm) — Arm Cortex-M4 with DSP and FPU at up to 100 MHz, 512 Kbytes of Flash and 128 Kbytes of SRAM, powered from 1.7 V to 3.6 V, listed Active with a 10-year longevity commitment on st.com (datasheet DS10314 Rev 8). Run current is 100 µA/MHz with peripherals off. The selection point is the package and temperature code: the U6 suffix is the -40 to +85 °C industrial grade in the 48-pin footprint — the U7 code raises the limit to +105 °C in the same footprint and the CEY codes move to a 49-bump WLCSP — so match the full code to the board footprint and thermal design, not just the STM32F411CE base name. Selection advice: the same family in LQFP-64 uses the STM32F411RE order codes; pin count is not interchangeable, so verify the exact code on st.com before layout.
