The STM32F401RE is the STMicroelectronics microcontroller assembled on the NUCLEO-F401RE board as STM32F401RET6: an Arm Cortex core-based STM32 in a 64-pin LQFP64 package. The full ordering code encodes the pin count (R), flash size (E, 512 KB) and package (T, LQFP).
This page records only what the currently admitted official sources state about the chip itself. Core architecture details, maximum clock frequency, SRAM size and peripheral inventories live in the STM32F401 datasheet, which is not yet an admitted source here — those figures are left out rather than filled in from memory.
Capabilities
| Capability | What the sources say | Source |
|---|---|---|
| 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 |
