The Cortex-M4 core includes a single-precision floating-point unit (FPU) and DSP instructions, so you can run sensor fusion, motor-control loops, or audio filtering without a separate math coprocessor. Program memory is 512 KB of Flash, with 96 KB of SRAM for data and stack — enough headroom for a real-time OS and a moderate application image.
The LQFP footprint is straightforward for two-layer boards, unlike finer-pitch BGA packages.
The STM32F401RET7 is available to order through independent distribution.
The STM32F401RET7 and STM32F401RE share the same base product number (STM32F401) and the same 512 KB Flash and 96 KB SRAM. The T7 suffix specifically denotes the 64-pin LQFP with extended temperature range.
The STM32F401RET6 and STM32F401RET7 are functionally identical in core, memory, and peripherals. If your application operates within the RET6's range, the RET7 is a drop-in replacement.
