That core speed, paired with 1 MB dual-bank Flash and 564 KB SRAM, targets applications needing real-time DSP or motor-control loops without stepping to a dual-core part. ## Memory and peripheral allocation The 1 MB Flash is dual-bank, which allows live firmware updates over Ethernet or CAN while the application continues running from the other bank. The 564 KB SRAM is split across multiple blocks — enough for a real-time OS heap plus several large DMA buffers. The 18-channel 16-bit ADC array and two 12-bit DACs handle multi-axis current sensing and analog output without external converters. Brown-out detect and POR are integrated, so the external supervisor can be a simple resistor-capacitor pair. The 144-LQFP (20×20 mm) footprint is a standard hand-solderable QFP; no BGA reflow required for prototyping or low-volume production.","metaTitle":"STM32H733ZGT6 STM32H7 ARM Cortex-M7 MCU, 550 MHz","metaDescription":"STMicroelectronics STM32H733ZGT6: 32-bit ARM Cortex-M7 at 550 MHz, 1 MB Flash, 564 KB SRAM, 112 I/O, Ethernet MAC, CAN, USB OTG, -40 to 85°C, 144-LQFP.
