The core includes a double-precision FPU and a single-cycle multiplier, so the 216 MHz clock delivers sustained throughput for floating-point sensor fusion, audio processing, or driving a TFT display through the built-in LCD interface. ## Memory map and bus architecture — no dead cycles on the back-to-back read The 320 KB SRAM is split across multiple buses (ITCM, DTCM, AXI), so the Cortex-M7 can fetch instructions from Flash on the AXI bus while the DMA engine writes ADC data into DTCM — no arbitration stalls. The 512 KB Flash runs with ART Accelerator (adaptive real-time memory accelerator) that gives zero-wait-state execution up to 216 MHz for typical code. If your application needs more SRAM for frame buffers, the FMC (flexible memory controller) on the EBI/EMI interface can map external SDRAM or SRAM, though the BGA package limits prototyping options compared to an LQFP variant. The lifecycle record carries an EOL-hot flag alongside an Active status, which means production is still running but the end-of-life transition may be in progress.","metaTitle":"STM32F746NEH6 STMicroelectronics ARM Cortex-M7 MCU, 216MHz","metaDescription":"STM32F746NEH6 32-bit ARM Cortex-M7 MCU at 216MHz, 512KB Flash, 320KB SRAM, 168 I/O, Ethernet, USB OTG, -40 to 85°C, 216-TFBGA.
