STM32F401RE 是装配在 NUCLEO-F401RE 板上的意法半导体微控制器（完整订货型号 STM32F401RET6）：基于 Arm Cortex 内核的 STM32，64 针 LQFP64 封装。完整订货码依次编码引脚数（R）、flash 容量（E，512 KB）与封装（T，LQFP）。
本页只记录当前已准入的官方来源对芯片本身的陈述。内核架构细节、最高时钟频率、SRAM 容量与外设清单属于 STM32F401 数据手册——它尚未在本站准入，因此这些数字留空，而不是凭记忆填补。

| LQFP64 package, 64 pins | “Arm Cortex core-based STM32 microcontroller in LQFP64 package”; the Nucleo-64 board is “designed around the STM32 microcontrollers in a 64-pin LQFP” (official wording). Same package for every Nucleo-64 variant; the R in STM32F401RE encodes the 64-pin count. | UM1724: STM32 Nucleo-64 boards (MB1136) user manual · Section 1 Overview; Section 7.12; Table 2 |
| 512 KB flash (ordering code E) | “E for 512 Kbytes” — flash-size letter of the STM32 ordering code explained in the codification table. The capacity is read from the official ordering-code scheme, not from a chip datasheet; no other chip figures are asserted here. | UM1724: STM32 Nucleo-64 boards (MB1136) user manual · Table 2: Codification explanation |
