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.
