Product details

Active production Cortex-M4 for cost-sensitive control

The STM32F401CCU6TR is an STM32F4-series 32-bit ARM Cortex-M4 microcontroller clocked at 84MHz, with 256KB of Flash and 64K x 8 of SRAM. The 48-UFQFPN (7x7) package with exposed pad keeps the board footprint small while the pad aids thermal transfer under continuous load.

The base product number STM32F401 covers a range of Flash/RAM and package options, so a future density upgrade stays pin-compatible within the family.

TR suffix — tape-and-reel for volume assembly

The non-TR variant (STM32F401CCU6) ships in tray or tube; the silicon and firmware are identical. For a production BOM, the TR suffix is the correct choice to avoid manual handling.

Frequently asked questions

What is the difference between STM32F401CCU6 and STM32F401CCU6TR?

The difference is packaging only: STM32F401CCU6 ships in tray or tube, while STM32F401CCU6TR ships in Tape & Reel (TR) format for automated assembly. The silicon, firmware, and all electrical specifications are identical.

Does the STM32F401CCU6TR require an external oscillator?

No, it includes an internal oscillator sufficient for many applications. For precision timing (USB, high-speed communication), an external crystal can be added, but the internal oscillator allows a minimal BOM for basic control tasks.

What are the alternatives to STM32F401CCU6TR?

A lower-power alternative is the STM32L151CBU6A, which uses a Cortex-M3 core at 32MHz with similar peripheral set but lower active current. However, it lacks the DSP instructions and 84MHz throughput of the STM32F401CCU6TR, so it is not a direct pin-for-pin replacement — evaluate if your application can trade performance for battery life.
