216 MHz Cortex-M7 with 1 MB Flash — the compute and memory ceiling
The STM32F765ZGT6 is a 32-bit ARM Cortex-M7 microcontroller running at 216 MHz, backed by 1 MB of on-chip Flash and 512 KB of SRAM. That memory budget — 1 MB for code and constant data, 512 KB for stack, heap, and DMA buffers — covers a full RTOS footprint, a TCP/IP stack, and a real-time control loop without external memory.
144-LQFP footprint — board integration and thermal path
At the low end, 1.7 V operation near the threshold means the brown-out detector (BOR) must be configured to the correct trip level to avoid spurious resets during power-up.
Active lifecycle — no obsolescence watch for this code
RoHS3 compliant (2011/65/EU + 2015/863) per the manufacturer's declaration.
