STM32H735ZGT6
Overview
The STM32H735ZGT6 is a high-performance STM32 microcontroller from STMicroelectronics based on an Arm Cortex-M7 core. It combines 1 MB of Flash and 564 KB of RAM, making it suitable for demanding embedded control, signal processing, and connected applications.
This device is typically used when a design needs substantial compute headroom, fast peripherals, and flexible firmware development on a mainstream MCU platform.
Why Choose This Part
This part gives you a strong balance of CPU performance, on-chip memory, and STM32 ecosystem support. The Cortex-M7 class core is a practical choice for applications that need both real-time behavior and more complex firmware, including DSP-like workloads and protocol handling. It is also a good fit if you want to stay within ST's widely used development and tooling ecosystem.
Applications
Getting Started
Common starting points include ST's Nucleo and Discovery boards in the STM32H7 family, along with STM32CubeIDE and the STM32CubeH7 firmware package. For debug and programming, an ST-LINK compatible probe is the usual entry point, and STM32CubeProgrammer is useful for flashing and basic device setup. If you are porting performance-sensitive code, pay close attention to clock tree configuration, cache settings, and RAM placement early in the bring-up process.
