Memory sizing and peripheral headroom
512 KB Flash and 320 KB SRAM place the STM32F745ZET6 in the mid-density tier of the STM32F7 family. That is enough for a TCP/IP stack, a small file system, and a control loop without paging.

Frequently asked questions
What is the operating frequency of STM32F745ZET6?
The STM32F745ZET6 runs at 216 MHz, which is the maximum core clock for this ARM Cortex-M7 device. That clock rate, combined with the Cortex-M7's dual-issue pipeline and single-precision FPU, gives it enough throughput for real-time control loops and communications processing without needing an external DSP.
Can STM32F745ZET6 replace STM32F746ZET6?
The STM32F745ZET6 and STM32F746ZET6 are pin-compatible in the same 144-LQFP package and share the same core architecture and peripheral set, but the STM32F746 adds a TFT LCD controller and a hardware JPEG codec. If your design does not use the display controller or JPEG accelerator, the STM32F745ZET6 is a functional drop-in replacement at a lower memory tier. Verify the firmware memory map — the STM32F746 carries 1 MB Flash versus 512 KB on this part.
