Product details

Cortex-M4 at 84 MHz — what the core clock buys you

The STM32F401RET6JTR: The Cortex-M4 core runs at 84 MHz with a single-precision FPU and DSP instructions.

Fifty I/O lines in the 64-LQFP package give enough GPIO for a mixed-signal control board with parallel LCD or external memory interface.

The base product number STM32F401 covers a range of density and package options, so if a future design needs more Flash or a smaller footprint, the migration path stays within the same family without a full software port.

Frequently asked questions

What is the difference between STM32F401RET6 and STM32F401RET6JTR?

The STM32F401RET6 and STM32F401RET6JTR are electrically and functionally identical. The suffix 'JTR' denotes Tape & Reel packaging for automated assembly, while the base STM32F401RET6 typically ships in trays or tubes. The silicon, firmware, and pinout are the same.

What is the maximum operating frequency of STM32F401RET6JTR?

The maximum core clock speed is 84 MHz. At this frequency the Cortex-M4 FPU and DSP extensions provide single-cycle MAC operations, making the part suitable for real-time control and audio processing tasks.
