The STMicroelectronics STM32H733ZGT6 is a single-core ARM Cortex-M7 MCU from the STM32H7 series, clocked at 550 MHz. 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.
