STM32F401 in STM32 Family
The STM32F401 sub-family, manufactured by STMicroelectronics, represents the entry-level access point to the high-performance STM32F4 series. Built on the ARM Cortex-M4 core with a floating-point unit, these microcontrollers provide a balance of dynamic power consumption and processing performance. They are designed for applications requiring high computational throughput in a power-constrained profile, serving as a popular upgrade path from the Cortex-M3 series for DSP-heavy tasks.

| Part Number | I/O Pins | Package | Stock |
|---|---|---|---|
| STM32F401VET6 (STMicroelectronics) | 81 | LQFP-100 | 2,994 |
| STM32F401RE (STMicroelectronics) | 50 | LQFP-64 | 2,408 |
Variants within the STM32F401 family primarily differ based on their memory density and package footprint. Flash memory capacities range from 128 KB to 512 KB, while package options span from small UFQFPN48 and WLCSP configurations for space-constrained designs to larger LQFP100 packages that provide a higher number of available GPIOs and analog inputs. Temperature ratings also vary, with standard and extended ranges available for industrial environments.
